CHAPTER 4

SAFETYThe above Safety Alert Symbol means ATTENTION!BECOME ALERT! YOUR SAFETY IS IN-VOLVED! It stresses an attitude of ‘‘Heads Up forSafety’’ and can be found throughout this Operator’sManual and on the machine itself.

BEFORE YOU ATTEMPT TO OPERATE THISEQUIPMENT, READ AND STUDY THE FOL-LOWING SAFETY INFORMATION. IN ADDI-TION, MAKE SURE THAT EVERY INDIVIDUALWHO OPERATES OR WORKS WITH THISEQUIPMENT, WHETHER FAMILY MEMBEROR EMPLOYEE, IS FAMILIAR WITH THESESAFETY PRECAUTIONS.

Our Company ALWAYS takes the operator and his/hersafety into consideration when designing its machineryand guards exposed moving parts for his/her protection.However, some areas can not be guarded or shielded inorder to assure proper operation. This Operator’sManual, and decals on the machine, warn of additionalhazards and should be read and observed closely.

DANGER‘‘DANGER’’ indicates an imminently hazard-ous situation which, if not avoided, will resultin death or serious injury.

WARNING‘‘WARNING’’ indicates a potentially hazard-ous situation which, if not avoided, could re-sult in death or serious injury.

CAUTION‘‘CAUTION’’ indicates a potentially hazardoussituation which, if not avoided, may result inminor or moderate injury. It may also alertagainst unsafe practices.

1. Disengage the tractor PTO.

2. Shut off the tractor engine, place the tractortransmission in park and/or lock brake ped-als to prevent any tractor movement.

3. On Auto-Electric control equipped balers,BEFORE leaving the tractor seat to performany function or maintenance, push “POW-ER” keypad to turn off power to the control.

4. Remove the starter switch key and take itwith you when leaving the tractor seat.

5. Wait for all movement to stop.

6. Remove the telescoping drive and ALL powerconnections from the tractor.

ONLY when you have taken these precautions canyou be sure it is safe to proceed. Failure to followthe above procedure could lead to death or seriousbodily injury.

MANDATORY SAFETY SHUTDOWNPROCEDUREBEFORE unclogging, cleaning, adjusting, lubri-cating or servicing the unit:

ADDITIONAL SAFETY REMINDERS

Some photographs, used in this manual, may showdoors, guards or shields open or removed for illustrationpurposes ONLY! BE SURE that all doors, guards andshields are in their proper positions and securelyattached BEFORE operating this unit!

ALWAYS wear safety glasses with side shields whenstriking metal against metal! In addition, it is recom-mended that a softer (non-chipable) material be used tocushion the blow. Failure to heed could result in seriousinjury to the eyes or other parts of the body!

NEVER use your hands to search for hydraulic fluidleaks; use a piece of cardboard. Escaping fluid underpressure can be invisible and penetrate the skin causingserious injury! If any fluid is injected into your skin, seea doctor at once! Injected fluid MUST BE surgicallyremoved by a doctor familiar with this type of injury organgrene may result.


SAFETY(Continued)

ALWAYS follow state and local regulations regardinguse of a safety chain and transport lighting when towingfarm equipment on public highways! A safety chainshould always be used to retain the connection betweenthe towing and towed machines, in the event ofseparation of the primary attaching system! BE SUREto check with local law enforcement agencies for yourown particular regulations. Unless otherwise prohib-ited, use a Slow–moving Vehicle (SMV) emblem.

Only a safety chain (NOT an elastic or nylon/plastic towstrap) should be used to retain the connection betweenthe towing and towed machines, in the event ofseparation of the primary attaching system. Refer to theOptional Features & Accessories chapter for safetychain.

Good safety practice dictates that you NEVER tow animplement that does not have brakes, unless the towingvehicle weighs at least one-and-one half (1-1/2) timesthe weight of the towed implement and its load. For anypublic highway travel and to be in compliance with thisrule, BE SURE that your tractor is heavy enough tocounterbalance the weight of the baler and a full-sizedbale.

Limit towing speed to 20 mph (32 km/h).

Always use adequate lights or safety warnings whentransporting the machine on public roads and after dark.Check with the local law enforcement agencies forspecific requirements.

BE SURE that the telescoping PTO drive rotates freelyinside the drive shield tubes at all times. Balers are

provided with two different types of telescoping drives;one drive has metal shield tubes and the other has plasticshield tubes. The drive with plastic shield tubes must beanchored to a hole in a part of the baler frame with thetie-down chain provided. The drive with metal shieldtubes MUST NOT be anchored.

Bales made with the Round Baler are LARGE, CYLIN-DRICAL and HEAVY. Serious personal injury orproperty damage could result if the bales are notcarefully and properly handled. NEVER eject or storebales where they could possibly roll downhill.

To ensure continued safe operation, replace damaged orworn-out parts with genuine GEHL service parts,BEFORE attempting to operate this equipment.

Our Company does NOT sell replacement tires. Inaddition, tire mounting, service or inflation can bedangerous. Whenever possible, trained personnelshould be called to service and/or mount tires, followingthe tire manufacturer’s instructions. If you do not havesuch instructions, contact your tire dealer or ourCompany. In any event, to avoid possible fatal or seriousinjury, follow the specific directives given in the Servicechapter of this manual.

BE SURE to review and comply with ALL safetyrecommendations set forth in the tractor operator’smanual.

REMEMBER, it is the owner’s responsibility forcommunicating information on the safe use and propermaintenance of this machine.

FIRE EXTINGUISHER

WARNINGIf a fire occurs eject the bale from the baler IM-MEDIATELY, move the baler up-wind 30 feet(10 m) or more away from the ejected bale,shut off the tractor engine and proceed to putout the fire with a fire extinguisher.



There is always the possibility of fire whenhandling dry forage materials. GEHL Compa-ny recommends that to limit the damage to theBaler and/or tractor in case of a bale fire, a fivegallon or larger, pressurized water type, fireextinguisher should be mounted on the trac-tor or Baler, as a minimum protection.

NOTE: A five gallon extinguisher should be suf-ficient to put out small fires that are burning the drymaterial that remains in the Baler, after the bale isejected. However, this size extinguisher is insuffi-cient to put out even a small fire in the bale.

WARNINGThe pressurized water fire extinguisher DOESNOT replace the dry chemical fire extinguish-er on the tractor (if so equipped). NEVER usea water–type fire extinguisher on electrical orfuel fires. Furthermore, to reduce the possibil-ity of a fire, keep crop build-up to a minimum,especially on the roller ends, the chain drives(behind the hinged shields) and in the pickupdrive area.

HOW BALER FUNCTIONS(Figs. 22 & 23)Crop material is picked off the ground by the 4-Tinebar,Closed-style Pickup and delivered to the throat of theunit where it is pressed by the Packing Roller against theLower Roller. The Rollers then carry the crop to theback of the unit where the crop meets the Belts which aretraveling toward the front of the unit. The Belts carry thecrop forward and over the top of the lower incoming matof material until it comes in contact with the Bale StarterFingers. The Fingers deflect material down into theincoming mat of material to form a roll of crop materialor bale core.

As the round core of material gets larger in size, the BaleStarter is lifted from the area to avoid contact with thebale. As the bale increases in size, the additionalBelting, required to wrap the bale, is released by the BeltShuttle as it moves toward the rear of the Baler. Belttension and bale density control is governed by the TotalDensity Control (TDC) system. The windrow anddriving pattern of the Baler operator determines howwell the material is distributed across the bale.

NOTE: It may be necessary to weave from oneside of the windrow to the other in order to properlydistribute crop into the baling chamber.

On manual control models, when the Bale Size Indica-tor reaches the preferred size, the twine can be wrappedaround the bale. Once tied, the bale is ejected by openingthe Gate and the process of forming another bale can berestarted. The maximum bale size is “5” (for RB1475)or “6” (for RB1875),

NOTE: It may be necessary to back up severalfeet before ejecting the bale to allow room to closeand latch the tailgate without contacting the cropwindrow.

HOW TDC SYSTEM FUNCTIONS(Figs. 24, 25 & 26)The Belt Tension and subsequent bale density iscontrolled by the Total Density Control (TDC) system.The major components of this system include aReservoir, two Density Cylinders, an adjustable Pres-sure Relief Valve, and a Manifold with a Trip Mecha-nism. This unique TDC system is self-contained and iscompletely independent of the tractor hydraulic system.The TDC system supplies a tensioning force to the Beltswhich, in turn, exerts a compressive force on theforming bale.

During the initial bale forming stage, the force exertedby the Density Cylinders onto the Belts is directly

related to the air pressure in the Reservoir. As the baleincreases in size, the additional Belting required isreleased by the Belt Shuttle as it moves toward the rearof the Baler. This rearward travel of the Belt Shuttleextends the Density Cylinders and forces hydraulic fluidout of the Cylinders, through a Manifold and into theReservoir. This additional fluid further compresses theair in the Reservoir and causes an increase of pressureresulting in Belt tension.

As the Cylinders continue to extend, the Valve TripMechanism is contacted by the Trip Spacer on the TripArm of the right Density Cylinder Clevis. As the ValveTrip Mechanism is triggered, the free flow path throughthe Manifold is blocked off and the hydraulic fluid isredirected through the adjustable Pressure Relief Valveon its way to the Reservoir. The Relief Valve works tocreate a pressure differential between the DensityCylinders and the Reservoir. This means that the fluidpressure in the Density Cylinders has to reach a presetvalue above the pressure in the Reservoir before theRelief Valve will relieve and allow the fluid to passthrough to the Reservoir.



As the bale continues to grow and the Cylinders continueto extend, the TDC system continues to function in themanner previously described. When the bale is ejectedfrom the Baler, the pressure in the line from the DensityCylinders to the Relief Valve drops below the pressurein the Reservoir. This causes a reverse flow of hydraulicfluid from the Reservoir back into the Density Cylin-ders. The Cylinders are retracted which in turn restoresthe Shuttle, the Belts and the Valve Trip Mechanism totheir original positions. The TDC system is once againready to start forming another bale.

Optimum Conditions & BaleDensity (Fig. 27)

Optimum haying conditions are a combination of cropmaturity and moisture content. Because of changingweather conditions, NOT all hay can be baled underideal circumstances. The TDC system enables the Balerto adapt to these less than ideal conditions. In particular,the density of the bales can be adjusted to be morecompatible with baling conditions.

As moisture content increases, the bale density can bedecreased. Using the illustration and table provided fora reference, several types of bales can be formed byaltering either or both the Trip Spacer on the Trip Armwhich is connected to the right Density Cylinder or theRelief Valve pressure setting. Changing the Trip Spacerlocation to one of the other lower holes, progressivelyincreases the core diameter by delaying activation of theValve Trip Mechanism.

Bale density can be adjusted for different crop condi-tions and moisture contents by adjusting the ReliefValve setting. Turning the End Disc assembly clockwiseinto the Valve Body increases the Relief Pressure andbale density. The adjusted setting can then be locked inplace by turning the Locking Ring clockwise until it issnug against the Valve Body.

Bale Handling & Storage

WARNINGBales made with a Round Baler are LARGE,CYLINDRICAL and HEAVY! Serious personalinjury or property damage could result ifthe bales are not carefully and properly han-dled. MAKE SURE the bale will not roll whenejected from the baler. BE SURE that thetractor used with any bale handler is largeenough to safely handle the weight of thebales. Front or rear counter-weights maybe required. Using a bucket–style front endloader to move bales creates a hazard, be-cause the bale can roll out of the bucketand down the loader arms onto the operator.Generally, agricultural tractor Roll-over Pro-tective Structures (2–Post ROPS) are notintended to protect against falling bales. DoNOT lift round bales with the standard loaderunless you have proper bale restraining de-vices.

Because the bales are cylindrical and very heavy, specialcare MUST be exercised when ejecting them andstoring them to keep them from starting to roll. Whenthe bales are moved, make sure that the original bottomof the bale stays at the bottom. When moving bales to astorage area, observe the following recommendations tominimize crop loss:

1. Select a well-drained area with complete exposureto the sunlight.

2. Place the axis of the bales north and south so thesun can dry out the cylindrical surface of the baleas it travels from east to west.

3. Where space allows, set several bales in a rowwith their ends pushed tightly together to form along cylinder. Make sure that you do NOT form awater dam using too many bales in a row withoutskipping a space. Make sure to always maintain aclear path for the water to travel away from thebales.

4. Keep the rows of bales far enough apart so that onerow will NOT overshadow the adjoining row andcut down on exposure to full sunlight.

5. When bales are stored outside in conditions of ex-ceptionally high rainfall (especially drivingrains), spoilage due to water penetration can be re-duced by placing the shingled cylindrical surfaceof the bale in the direction of prevailing rain orwind. The shingled surface can be determined byrunning your hand along the edge of the bale. Onthe shingled surface, your hand will slide smooth-ly. The unshingled surface will offer more resis-tance to your hand movement.

BalingAfter transporting the Baler to the field, adjust thePickup height according to crop conditions and landcontour; refer to the Pickup Flotation topic in theAdjustment chapter of this manual for details. TheBaler Pickup should be run as high off the ground aspossible while still being able to completely pick up allof the crop.

IMPORTANT: The Pickup assembly MUST becarried off the ground. Running the Pickup too lowto the ground will result in excessive Tine wear orbreakage and possible damage to the PickupStripper Bands and Headers, Cam and CamBearings.

Move the Baler into position with respect to thewindrow and BE SURE to check the path in front of thePickup and ahead of the Baler before starting to bale.Then, start the PTO, bring the tractor RPM up to thedesired operating speed and begin baling.



If the windrow has been prepared to less than the fullwidth of the Bale Chamber, it will be necessary to drivethe Baler in a weaving fashion to fill the Chamber andstart the bale core. If the windrow has been preparedfor the full width of the Pickup, either 45 to 52″ (1143to 1321 mm) for an RB1475 or 61 to 68″ (1549 to1727 mm) for an RB1875, the Baler can be drivenstraight down the windrow while observing that thebale starts and continues to form properly. To obtainthe most uniform bales, the windrow should, whereverpossible, be made at or slightly larger than the BaleChamber width.

When baling a windrow which is about 1/2 the width ofthe Bale Chamber and after the core has started, stop theweaving process and drive straight with the windrowentering the Pickup as far to one side as possible.Continue driving the Baler with the windrow enteringon one side until the rotating bale is approximately 3 to4″ (76 to 102 mm) higher on one side than the other.Then, quickly cross over so that the windrow enters onthe other side of the Pickup and continue filling that sideuntil it is 3 to 4″ (76 to 102 mm) higher than the otherside. Continue crossing over from side to side until afull-sized bale is formed.

When baling a windrow which matches the full width ofthe Bale Chamber, drive straight down the windrowuntil the desired full-sized bale is formed.

IMPORTANT: Continuous feeding of materialprovides for smoother starting and better baleformation. Avoid non-cylindrical bales and baleswith loosely packed outside edges. Bothconditions can allow the Belts to fall off the endsof the bale and possibly tear out the Belt LacingHooks. In addition, this type of bale will weatherpoorly. Proper material preparation is a veryimportant factor in making good-shaped bales.Refer to the Preparing for Field Operation chapterof this manual for further details.

Baylage (High Moisture Hay)(RB1475 Only)NOTE: Anyone experimenting with this typeof storage procedure, for the first time, shoulddo so with limited samples, to minimize potentiallosses.

NOTE: Due to the extremely HEAVY bale thatresults from high moisture baling, we recommendthat bale sizes be kept under a 4 ft (1.2 m) diame-ter. It is further recommended that Balage baling belimited to using only an RB1475 Baler and equip-ping it with an accessory Silage Scraper Kit. Referto the Optional Features & Accessories chapter forordering information.

BALE SIZE VISUAL INDICATOR(MANUAL & AUTOMATIC TWINECONTROL MODELS) (Fig. 28)

The Bale is full-size when it reaches 5 feet (1.5 m) indiameter for the RB1475 Baler or 6 feet (1.8 m) indiameter for the RB1875 Baler. As a matter of personalpreference, the bale forming process can be stopped atany time before this size. For this reason, the Bale SizeVisual Indicator is provided as a visual aid to formingconsistent sized bales.

OVERFILL PROTECTION(Figs. 22 & 23)

The Baler is designed with an Overfill Clutch mecha-nism which automatically stops the Pickup when thebale becomes oversized. If the bale becomes oversized,the Shuttle will activate the Overfill Clutch Actuatorwhich is linked by a Cable to the Pickup Drive to stopthe Pickup and prevent damaging the Baler. When thishappens, simply back the Baler out of the windrow andtie or wrap the bale in the normal manner.



MANUAL TWINE WRAP(Figs. 28 & 29)

NOTE: The procedure described is the manualsequence. The entire process of wrapping thebale with twine is done from the tractor seat.

The position of the Pointer on the Bale Size Indicatorcan be used as a fairly accurate gauge for forming thedesired size bale. When the desired size bale is formed,stop Baler forward travel. Then, swing the Twine Armso that it is straight back.

NOTE: The Twine Arm is actuated by movingthe Twine Arm Positioning Switch to the “FOR-WARD” position to move the Twine Arm from rightto left. Moving the Twine Arm Positioning Switch tothe “REV” (Reverse) position moves the TwineArm from left to right.

NOTE: By moving the Twine Arm to the middleof the Baler, appropriate lengths of twine arebrought out for starting to wrap a new bale.

Then, drive forward again to take in a small amount ofmaterial to start feeding the twine into the Baler.

DANGERNEVER attempt to clean or manually feed thebaler when it is running. Material feeds intothe baler faster than you can react to releaseit. You may become entangled in movingbelts, pick-up or rollers. Failure to heed canresult in death or serious injury.

When the twine can be seen moving into the Twine Arm,stop Baler forward travel. Allow the twine to make atleast one full wrap in this location and then move theTwine Arm to the left side.

NOTE: Moving the Twine Arm all the way to theleft engages and locks the Twine Cutoff Jaws in theopen position.

NOTE: Normally, the bale can be adequatelytied with two wraps of twine on the left side, severalwraps across the center of the bale and two wrapson the right side. If the material being baled is slip-pery, it will be beneficial to place two wraps of twineon the center of the bale before moving to the leftside in order to prevent the twine from sliding off theend of the bale. It may also be necessary to adjustthe positions of the end wraps depending on thecrop being baled.

When the Twine Arm returns all the way to the right, theTwine Jaws will snap closed and the twine will be cut.The wrapped bale can now be ejected from the Baler andbaling can resume.

AUTOMATIC TWINE WRAP SYSTEM

FeaturesThe Auto Twine Wrap Control System exhibits thefollowing features and characteristics:

1. AUTO/MANUAL Mode Selection - fully auto-matic tie system or manual tie system.

2. Continuous moving Twine Arm distributes twinein a helical pattern across the bale.

3. A daily bale counter which can be reset to Zero (0)

4. A lifetime bale counter which cannot be reset

5. The error message “SEt” is displayed when thetwine wrapping system is not functioning proper-ly (Refer to the Troubleshooting chapter).



6. Two spaced audible tones are sounded when thetie cycle starts.

7. The message “tIE” is displayed while the systemis in the twine tie sequence.

8. One audible tone is sounded and the message“OPEn” “GAtE” is displayed when the tie se-quence is through and the Baler is ready for thebale to be discharged. The message “OPEn”“GAtE” remains displayed until the bale is dis-charged.

9. One audible tone is sounded when the Tailgate isfirst opened and then repeated every eight secondswhile the Tailgate remains open.

10. Two quick audible tones are sounded when theTailgate is closed and latched.

OperationThe Control Module is a monitor and controller for theTwine Arm. When a bale is formed, a sequence is startedthat drives the Twine Arm across the face of the bale.The twine is applied in a predetermined helical patternacross the face of the bale and is designed to apply extratwine on each bale end.

Bales can be tied in a manual or fully automatic mode.The Control Module also keeps a daily and lifetimecount of bales made.

NOTE: This Auto Twine Control is NOT in-tended for use on Balers equipped with QuickWrap.

Operating System

The following are the typical Keypad selections toactivate and operate the Electronic Bale Wrap ControlSystem:

NOTE: If, after initial “Power Up”, the display onthe Tractor Module lights up and goes blank withina few seconds:

1. Check that the power cord from the Baler isconnected to the tractor and all connectionsare clean and tight.

2. Faulty Implement Module. See Dealer.

After “Power Up”, the system will automatically de-fault to the settings as they were before “PowerDown”. Keypad activations always require that theKeypad be pressed and temporarily held until abeep is heard and/or the Display changes.

“Power” Key

Press and hold the “Power” Key to power up (turn on)the control system.

To power down (turn off) the control system, press the“Power” Key. This will cause the display to go blank andthe control system will not accept any signals from thecab module or any sensors. However, bale wrappinginformation is preserved in memory (see Note, below).

NOTE: It is recommended to power down (turnoff) the control system by pressing the “Power” Keyanytime an interruption to the control system pow-er is anticipated. This will preserve the current balesize information by storing it in memory; if the con-trol system power is interrupted without poweringdown or in any other way (such as power loss dueto starting the tractor engine or disconnecting thePower Cable), the current bale size informationand the Bale Size Bar Graph will be lost.

NOTE: As noted above, pressing the “Power”Key will make the control system inoperable. How-ever, this does NOT eliminate all power consump-tion. If the Baler is going to be idle for a week ormore and remain hitched to the tractor, it is recom-mended that the Power Cord between the tractorand the Baler be separated to prevent draining ofthe tractor battery.

“Enter” Key

Whenever a key is pushed within the top two rows(Command Keys) of the keypad, a corresponding iconwill flash in the display. If no further commands areentered by pressing a key on the keypad within 5seconds, the flashing icon will stop and the system willreturn to its previous settings. In order for the system tounderstand and remember a new command, the com-mand must be followed by pushing the “ENTER” key.If the “ENTER” key is not pushed within 5 seconds, thesystem will return to its previous setting.



Pressing the “ENTER” key will also mute the audiblealarm when an error message is displayed. Muting thealarm will NOT clear the display of the error code untilthe error is corrected. Once the error is corrected,pressing the “ENTER” key will clear the display.

“Bale Size” Key

OR

To adjust the bale diameter:

1. Press the “BALE SIZE” key

The current programmed bale size will beshown on the display and the word “SIZE”will be flashing on and off at the lower lefthand side of the display.

2. Press the “+” key to increase bale size or press the“–” key to decrease bale size.

The Bale diameter shown in the display willrespond to key entries and will increase ordecrease in 6″ increments. Likewise, thelimiting icon on the Bar Graph will move upand down and align itself with the selectedbale size diameter.

3. Press the “ENTER” key to save the programmingchange made to the bale size.

“Twine/Net” Key

NOTE: The current mode of wrapping can beidentified by the icon in the top right center of the

display; either for NET mode or for TWINEmode.

To alternate between TWINE and NET modes formaking changes:

1. To enact a change in the wrapping mode, press the“TWINE/NET” key. The alternate wrappingmode should begin flashing in the top right centerof the display.

2. Verify that the flashing icon represents the desiredwrapping mode. If it does, press “ENTER” tosave. The flashing icon should have switched tosolid.

NOTE: The control will not switch from twine tonet if it is not programmed with the correct code fora Quick Wrap baler. See Machine OperatingCodes topic in this chapter for Baler codes.

Amount of Wraps

The values for wrapping a bale are different for twinethan they are for net. When adjusting the number ofwraps, you are only changing the value of wraps thatpertain to the wrapping mode for which you areprogrammed. For example, if programmed to twine,only the number of twine wraps change. If programmedto net, only the number of net wraps change. If thecontrol is switched from twine to net, the system willremember any previous setting for the number of netwraps. The same holds true when switching from net totwine.



OR

To adjust the number of wraps (Auto Mode Only), presseither the “+” or “–” key. A numeric value will appearin the display along with the flashing icon “WRAPS”.To increase the numeric value (number of wraps),continue to push the “+” key. To decrease the number ofwraps, push the “–” key.

When in the “TWINE” Mode, the numeric value is theapproximate number of wraps of twine placed across thecircumference of the bale. The value increases anddecreases by increments of 1 between 1 and 10, with 10being the greatest amount of twine.

NOTE: Settings 4 and 5 will apply the sameamount of wraps (approximately four wraps)across the bale. However, a setting of 4 or lower willplace approximately 2-1/2 end wraps while a set-ting of 5 or higher will place approximately 3-1/2end wraps. On Settings 1 and 10, the Twine Armwill NOT stop when travelling from the left side tothe right side when applying twine.

When in the “NET” mode, the numeric value on thedisplay is the approximate number of times the net iswrapped around the circumference of the bale (Onewrap equals one time around the bale). The system canbe adjusted in 0.25 wrap increments between 1.25 and9.75.

“Cycle” Key

To start the wrapping cycle early (Auto Mode Only):

1. Press the “CYCLE” key. The flashing cycle iconshould be visible in the upper right hand corner ofthe display. This indicates that the control systemhas been switched to the wrapping mode.

2. Press the “ENTER” key. This confirms that youwant to start the wrapping cycle. The actuators foreither the netting or twine arm should have startedand continued in the automatic wrapping cycle.

Bale Count (Daily)To clear the daily count, press and hold the “–” key andthe “+” key simultaneously until a “0” appears on thedisplay.

Press and Holdfor 5 Seconds

Bale Count (Lifetime)To check the lifetime count, press the “ENTER” key andhold it until the first number (1000’s digit) is displayed.Then, release the “ENTER” key before the secondnumber (hundreds) is displayed.



NOTE: The display will alternate between twosets of numbers. For a count under 1000, the dis-play will first show “0” (the 1000’s digit) and the se-cond display will be the count under 1,000. Forcounts over 1,000, the 1st display will be the num-ber of 1000’s and the second display will be thecount under 1,000.

Example:A lifetime count of 13,568 would alternatelydisplay as 13 (for the 1000’s count) and 568 (forthe count under 1,000).

2ndFlashedCount

NOTE: The maximum lifetime count can be999,999. To clear the display of the lifetime countmode, press “ENTER” while the second set ofnumbers (hundreds) is on the display.

SWITCHING FROM AUTO TOMANUAL MODE

Through the course of daily operation in the “AUTO-matic” mode, it may become necessary to switch to the“MANUAL” mode to perform a troubleshooting se-quence, an adjustment or restart the system after aparticular Error Message has been acknowledged andrectified. To change from “AUTO” to “MANUAL”,power-up (if NOT already power-up), press the“MANUAL/AUTO” key, hear a single beep andobserve that the Display shows the MAN Icon flashing.Then, press the “ENTER” key to lock-in the “MANU-AL” mode.

Operation in the Manual ModeThe primary function of the Manual Mode is tomanually control the extension and retraction of thetwine arm actuator or Quick Wrap actuator. Typically,this is required to route twine through the twine arm orservice the baler.

The Manual Mode can be used when building andwrapping a bale, should the Auto Mode becomeenabled. When operating in the Manual Mode, many ofthe monitoring sensors on the baler are electronicallyswitched off. The Manual Mode will allow the operatorto select twine or net, change bale size, and count bales.The bale size Bar Graph will function the same as in theAuto Mode as will the tailgate open and close icon withthe go arrow.

NOTE: If the bale size sensor or the tailgatesensor were to become disabled, the display willnot function properly. However, it will still be pos-sible to operate the actuators manually, providingthere is sufficient power to the implement controlmodule and the actuators.

The Manual Mode does not notify the operator when thewrapping is started. The flashing cycle icon will neverstay on solid. The flashing icon is only used as anindicator to inform the operator that the manual tiesystem is in process and that the actuator is not in thehome position.

Manual Mode Twine Arm Extension& Retraction

When in the “MANUAL” mode, the following steps canbe carried out to extend and retract the Twine Arm inorder to facilitate twine routing or whatever needs to bemanually accomplished:



1. Press and hold the (+) “EXTEND” key, hear abeep, and observe that the “CYCLE” Icon comeson and continues to flash as the Twine Arm contin-ues to move away from the “home” position. Re-lease the key to stop Twine Arm movement.

2. Press and hold the (–) “RETRACT” key, hear abeep, and observe that the “CYCLE” Icon comeson and continues to flash as the Twine Arm contin-ues to move toward the “home” position. Releasethe key to stop Twine Arm movement.

NOTE: The Twine Arm must have stalled in theHome Position before the flashing cycle icon willdisappear. The system will not accept any furthercommands until the “CYCLE” icon is cleared fromthe display.

Manual Quick Wrap Activation& De-activation

When in the “MANUAL” mode, the following steps canbe carried out to extend and retract the Wrap ControlActuator whenever this needs to be manually accom-plished:

1. Press and hold the (+) “EXTEND” key, hear abeep, and observe that the “CYCLE” Icon comeson and continues to flash as the Wrap Control Ac-tuator Shaft continues to move out. Release thekey to stop Actuator movement.

2. Press and hold the (–) “RETRACT” key, hear abeep, and observe that the “CYCLE” Icon comeson and continues to flash as the Wrap Control Ac-tuator Shaft continues to retract. Release the keyto stop Actuator movement.

NOTE: The Net Wrap Actuator must havestalled in the Home Position before the flashingcycle icon will disappear. The system will not ac-cept any further commands until the “CYCLE” iconis cleared from the display.

% Of Net Left

When operating in the Net Mode, the control systemwill keep track of the amount of net being consumed,which takes into account the number of wraps and balediameter. The system works best when using thesuggested net supplied by Gehl dealers. Reset the % ofnet left value shown each time you add a new roll of net.To do this, push the “CYCLE” key twice and hold for 5seconds the second time.

To show the % of net left on the display, push the cycletwice. The value on the display will represent theamount of net left on the net roll.

MANUALLY BUILDING A BALE TOTEST AUTO–ELECTRIC CONTROLSYSTEM

PreparationUnder certain conditions it may be necessary to test theAuto–Electric Control System by manually simulatingthe building of a bale. To simulate building a bale,proceed as follows:

1. Secure the Baler in a safe, stable and level locationto avoid any inadvertent repositioning of the ma-chine. The Tailgate should be in the closed andlatched position.

2. Disconnect the Baler Driveline from the tractorand place the tractor end of the Driveline onto theDriveline Support provided on the Baler.

Required Equipment3. The following equipment is need to be able to per-

form the simulated bale:

a. A 12 Volt DC power supply capable of de-livering a 20 ampere flow.

b. Two people capable of spinning the TwineWheels.

c. One small magnet.

4. Connect the Auto–Electric Control System to the12 Volt DC power supply. Check that all WiringHarnesses are securely fastened.

5. Become familiar with the Auto–Electric ControlSystem as described in the Operation chapter ofthis Operator’s Manual. Refer to the Operationand Troubleshooting chapters of this manual ifproblems occur during the following procedure.

6. Power up the Auto–Electric Control System bypressing and holding the Power Key.

Machine Operating Codes7. Check that the Control System is programmed for

the correct Baler model. Press “+” and“MANUAL/AUTO” simultaneously (NOTE: +will increase the code and – will decrease thecode). Select “+” or “–” until the correct code thatmatches your Baler appears in the display. See thefollowing table to determine the correct code.Press “ENTER” Key.

Code # Baler Model & Wrap System

cd1 1475 with Twine Wrap ONLY

cd2 1475 with both Twine & Quick Wrap

cd5 1875 with Twine Wrap ONLY

cd6 1875 with both Twine & Quick Wrap

Select “AUTO” Mode

8. If the word “AUTO” does not appear on the top ofthe display, select the “MANUAL/AUTO” Key.After the flashing “AUTO” icon appears on thedisplay, select the “ENTER”Key. The displayshould appear as follows;

NOTE: It is important to have an arrow dis-played in front of the “BALER” icon to indicate thateverything is functioning properly.

Program “BALE SIZE”

9. Select the “BALE SIZE” Key. The words “BALESIZE” should appear flashing in the lower portionof the display. Push “+” or “–” (“+” to increase,“–” to decrease) until 3.00 appears in the display.Press the “ENTER” Key within 5 seconds to savethe 3.00 foot bale diameter value.

Select Wrapping System

10. If the Twine icon is not showing on the top of thedisplay, push the “TWINE/NET” Key and theTwine icon should appear on the top of the display.Press the “ENTER” Key within 5 seconds to savethe Twine Tieing mode.

Program Twine Wrap Density

11. Press the “–” Key. This will display the currentvalue for the twine application and a flashing“WRAP” icon will appear on the bottom of thedisplay. Use the “–” Key to toggle the twinedensity to 1. Press the “ENTER” Key within 5seconds to save the value.



Building a Bale12. If the “GO ARROW” appears in the front of the

Baler icon, you can proceed to build a bale. Tobuild a bale, toggle the Bale Size Sensor up anddown. The Bale Size Sensor is located on the leftside of the Baler in the top front corner. The Sensorpivots about the Shuttle Stabilizer Sprocket. Eachtime the red light on the cord end of of the Sensorflashes, a count is being registered. After 9 counts,the Bar Graph on the display should begin to grow.Continue to toggle the Sensor. When the BarGraph reaches the 2-1/2 foot mark, one (1) audiblesignal will sound and the the Bar Graph will flashon and off. Keep toggling the Bale Size Sensoruntil three (3) audible signals are sounded and aflashing “CYCLE” icon appears in the upper righthand corner of the display (the “GO ARROW”will also disappear). At this point, the Twine Armshould extend and point directly to the back of theBaler while pausing.

13. The Twine Arm will remain at the pause positionuntil one of the following conditions occur:

a. If both twines have started on the bale (ac-complished only when both Twine Wheelshave rotated simultaneously), the TwineArm will advance to the left side of the Balerto apply end wraps and then proceed to“home” while making intermittent stops.

b. If, within 15 seconds, only one twine startson the bale (accomplished when only oneTwine Wheel rotated), the Twine Arm willstill wrap the bale, but with only one string.Once the wrapping mode is completed, anE–1 error code will display on the control in-dications that the bale was wrapped withonly one twine. The operator then has theoption to correct the problem and rewrap thebale by pressing the “CYCLE” and “EN-TER” keys or to eject the bale with only asingle twine.

c. If, after 15 seconds, neither twine has startedon the bale (accomplished when neitherTwine Wheel rotated), an E–3 error messagewill display on the control and the TwineArm will return to the home position.

Open Tailgate

14. Simulate opening the Tailgate by passing amagnet past the Tailgate switch. The“TAILGATE” icon should appear and thendisappear when the magnet is removed. The BaleSize Bar Graph should have also disappeared, theBale Count incremented by one, and the “GOARROW” icon should have reappeared in front ofthe “BALER” icon.

15. Repeat Steps 12., 13. & 14., if desired.



QUICK WRAP GENERALINFORMATION (Fig. 40)By design, either 1475 or 1875 Auto-Electric Balers canbe operated with either the Quick Wrap System or theTwine Tie (Wrap) System.

NOTE: In either case, only one or the other balewrapping system can be operated at a time. Refer tothis Operator’s Manual for Twine Tie System opera-tional information.

QUICK WRAP OPERATION

Principle of OperationWhile operating the Baler to build the bale, the wrappingsystem is NOT operating. When the bale reaches 6″(152mm) before the predetermined size, the TractorModule Bale Size Bar Graph will flash and a single beepwill be heard. Continue baling until the Bale Size BarGraph becomes a solid line and the System beeps threetimes. Stop forward travel IMMEDIATELY and back upa few feet. After shifting the tractor to park or neutral,continue to run the PTO. The Tractor Module Go Arrowwill disappear and the “CYCLE” icon will begin toflash.

NOTE: Forward travel MUST be stopped IM-MEDIATELY to prevent the crop from being placedon the outside of the Net material.

When the wrapping cycle begins, the Electric Actuatorwill extend causing the Knife Blade Holder to rotate theBlades away from the Front Guide assembly and releasethe end of the Netting. In addition, as the Blade Holderrotates, it drives the Rubber Drive Roller by means of aone-way overrunning clutch, to advance the Nettingtowards the Feeder Belts. The Feeder Belts willsandwich the Netting between the (bale forming) Beltsand the Feeder Belts and carry the Netting toward thebale. The “CYCLE” icon will go solid. As the net isfeeding onto the bale, the one-way clutch will beoverrunning on the blade holder shaft. The last 1-1/2″(37 mm) of the Actuator stroke will cause the Pivot Plateto compress the Spring on the Brake Tension Arm. TheBrake will then increase the drag on the Drive Roll andincrease the Netting tension. There is also a Sensormounted on the right side of the Steel Drive Roll whichmeasures the amount of Netting placed on the bale.When the correct amount of Netting has been distrib-uted, the Actuator will be retracted. While the Actuatoris being retracted, the Strap (Fig. 43) will hold Springtension to maintain proper Netting tension. At the endof the Actuator retraction cycle, the Brake will bereleased, the Blade will cut and hold the Netting and the“CYCLE” icon Indicator will extinguish and the Systemwill beep twice indicating the tying cycle is completed.

NOTE: It may be necessary to back up severalfeet before ejecting the bale to allow room to closeand latch the Tailgate without contacting the cropwindrow.

The bale can now be ejected and the bale formationprocess can be restarted. As the End Gate is opened and



the bale is ejected, the “BALER” icon displays an openEnd Gate. As the End Gate is closed, the “BALER” icondisplays a closed End Gate. When the System isrecycled and ready to bale, the “BALER” icon willdisplay the Go Arrow and the System will beep once.

The Baler can be operated with either a conventionalTwine Tie system or the Quick Wrap system. For theTwine Tie system, refer to information provided in theAuto-Electric Control topic of the Operation chapter ofthis Operator’s Manual.

Wrapping The Bale

At least two complete wraps should be used for normalbaling conditions. More wraps may be required fordifferent conditions or to increase bale weatherability. Toadjust the number of wraps, depress the “+” or “–” key onthe Tractor Module. A numeric value indicating theapproximate number of wraps will appear in the displayalong with the flashing “WRAPS” icon. To increase thenumber of wraps per bale, depress the “+” key, followedby the “ENTER” key. To decrease the number of wraps perbale, depress the “–” key followed by the “ENTER” key.The amount of wraps per bale can be adjusted from 1.25to 9.75 wraps in 0.25 wrap increments.

When the bale size is changed, it WILL NOT benecessary to adjust the amount of wraps to compensatefor the change in size. The system automaticallycompensates for the changes in bale size and PTOspeed.

Use the following charts as a guide for selecting thenumber of wraps for a given crop:

2. Locate the source of the plugging. The most likelyplace to look is in the area of the Quick Wrap DriveRoller and Knife. If Netting should wrap aroundthe Rubber Drive Roller, the Actuator should be inthe fully retracted position before attempting tounwrap the Rubber Drive Roller. It is best to cutthe Netting the entire length of the Rollers. BESURE NOT to cut into or damage the RubberDrive Roller. After the Netting is cut, rotate theRubber Drive Roller by hand while pulling the cutNetting free from the Roller. It may also be neces-



sary to remove the Knife Shield (Fig. 41) and RearGuide Assembly to access the plugged area.Check to make sure that the Chute area, betweenthe Drive Rollers and the Feeder Belts, is free fromobstructions, allowing the Netting to drop down tothe Feeder Belts. If necessary, re-install the Net-ting following the Quick Wrap Roll Installationprocedure in this chapter.

3. As required, the Rear Guide Assembly should bepositioned so that a 1/8 to 3/16″ (4 to 5 mm) gapexists between the Rubber Drive Roller and theRear Guide Assembly. Then, reinstall and rese-cure all Shields in their correct positions and, ifnecessary, adjust proper Pinch Roller Compres-sion Spring tension, on both ends of the Roller, be-fore resuming operation.

IMPORTANT: When removing the wrapped(plugging) material from the Rollers, NEVER cutinto Rubber Roller or Belts with a knife. Cuts inRoller or Belts will cause more frequent wrappingproblems and necessitate Roller and/or Beltreplacement.

Material Removal From PinchRollers (Figs. 43 & 44)Perform the following steps if the Pinch Rollers becomewrapped with Netting:

1. Remove the wrapped material by gathering theends in your hand and pulling.

2. Check the Rollers for any rough edges or protru-sions and file down, if necessary.

NOTE: It may be necessary to readjust theDrive Roller Chain if the Pinch Roller tension haschanged.

3. Reroute the Net end per the detailed informationprovided in Fig. 41 and on the decal located insidethe Tailgate cover.

4. Close all Shields and secure all Latches.

EJECTING THE BALE

WARNINGBales made with the Round Baler are LARGE,CYLINDRICAL and HEAVY! When ejected ona flat surface, the momentum of the bale com-ing off the bale discharge ramps, could carrythe bale as far as 10 feet (3 m) behind the baler.On a hill or incline, this distance could bemuch farther. Serious personal injury or prop-erty damage could result if the bale is ejectedtoward a sloping surface and allowed to rollaway uncontrolled!

The following procedure should be followed, in se-quence as described, for ejecting a bale:

1. Stop the PTO (if desired) and back the Baler ashort distance away from the windrow.

NOTE: Stopping the PTO, while opening theRear Gate, will result in a neater looking bale.

2. Activate the tractor hydraulic control lever andfully extend Gate Cylinders to open Rear Gate.

3. If necessary, engage the PTO at a very low RPMand the bale will roll off the lower Rollers.

4. With the PTO running at low RPM, drive the Balerahead and close the Rear Gate by retracting theGate Cylinders.



IMPORTANT: BE SURE to fully retract the GateCylinders to allow the Gate Latches to engage andlock. The PTO should be kept running while closingthe Gate to reduce the possibility of Belt damageand to help prevent the Bale Starter from hangingup on the Belts. Before proceeding to start forminganother bale, check to see that the Bale Starter isin the “down” position.

BALE COUNTER (Fig. 46)(Manual Twine Wrap System Only)

The Manual Control Baler is provided with a BaleCounter which indicates the number of times the Gatehas been opened to discharge a bale. The Bale Counteris located behind the large Hinged Covers on the rightside of the Baler.

UNPLUGGING & TRASH REMOVAL(Figs. 48, 49 & 50)

If the Baler becomes plugged, the following procedureMUST be used to safely clear the Baler:

1. Back out of the windrow.

2. Disengage the tractor PTO and open the Tailgate.


DANGERALWAYS exercise the MANDATORY SAFETYSHUTDOWN PROCEDURE before unpluggingor removing trash from the baler.

4. Lock Tailgate open by turning or depressing GateCylinder Lockout Valve (See Figs. 5 & 7).

5. Remove the Windguard. The Windguard is aquick disconnecting Guard that can be removedby pulling out and rotating the Windguard Retain-ing Lever 90°. The Windguard Retaining Lever islocated on each side of the Hitch.

6. Pull out loose material from on top of plugged ma-terial.

7. When the plug occurred, the Pickup probably con-tinued to run and balled up material on top of thePickup. Pull the material out from the underside ofthe in-going windrow between the windrow andthe Pickup.

8. When the material becomes hard to pull out/off ofthe Pickup, place the Reversing Wrench on theCross Shaft and press downwards on the Wrench(Fig. 49). This will rotate the Pickup and PackingRolls backwards, backing the material out of thepinch points between the Packing Roll and Pick-up.

9. If you have been successful in unplugging theBaler in Step 8., proceed to Step 10. Occasionallyyou may be unable to reverse the Baler by handusing the Reversing Wrench. In some cases, it willbe necessary to eject the partially completed balein order to gain access to the inside of the Baler.When this occurs, the following steps MUST befollowed:

a. Remove the Reversing Wrench and return itto its proper storage position.

b. Reconnect the PTO disconnected in Step 3.

c. Start tractor, engage PTO and eject thepartial bale that is formed in the Chamber.The partial bale can be unrolled andre–baled.

d. Again exercise the MANDATORYSAFETY SHUTDOWN PROCEDURE(Page 10).

e. With the baling chamber cleared, go underthe raised and locked Tailgate and remove asmuch material as possible from the rear ofthe Baler. Now, using a bar or long woodenpole, bump material from between thePacking Rolls, forward, toward the tractor.NEVER use your hands or feet to clear cropfrom this position.

WARNINGNEVER go under a raised tailgate without firstplacing the gate cylinder lockout valve in thelocked position. See Figs. 5 & 7 for details.

WARNINGDO NOT put your hands or feet betweenthe packing roll and lower feed roll. NEVERuse your hands or feet to dislodge cropfrom between the packing roll and lowerfeed roll. The packing roll is spring loadeddownward and will entrap you.

10. After material is unplugged from the PackingRoll/Pickup area, remove any trash that may havebuilt up on top of the belts or on top of the StarterFinger Assembly.

11. Rotate the Starter Finger Assembly upward byhand making sure that none of the Fingers makecontact with the Stripper Roll. If any of the Fin-gers touch the Stripper Roll, they MUST bestraightened BEFORE operation can continue.

12. AFTER unplugging, replace the Windguard,place the Gate Cylinder Lockout Valve in the openposition and return the Reversing Wrench to itsproper storage position.



WARNINGALWAYS remove the reversing wrench fromthe cross shaft and return it to its storage BE-FORE resuming baler operation.

13. Go through the proper start-up procedure, engagetractor PTO at a low RPM and close and latch theTailgate.

NOTE: If the Baler is equipped with an Auto-Electric Control System, the “GO ARROW” iconMUST be visible on the Tractor Control Module BE-FORE baling can resume. If the “GO ARROW” iconis NOT visible, with the PTO running, open andclose the Tailgate again.

CHAPTER 7ADJUSTMENTS

WARNINGBEFORE adjusting this unit, exercise theMANDATORY SAFETY SHUTDOWN PROCE-DURE (page 10).

AXLE HEIGHT (Fig. 51)

The Baler Axle height can be adjusted to four differentlevels by repositioning and/or rotating the Spindleassemblies. The factory set height shown is appropriatefor most normal field conditions. By rotating the Spindleassemblies 180°, the Baler can be lowered approximate-ly 3-3/4″ (95 mm). This setting may be useful when usinga tractor with a high drawbar ground clearance. TheBaler is shipped in the second highest possible setting.

BALE DISCHARGE RAMPS (Fig. 51)

Bale Discharge Ramps are mounted to the back of theBaler Axle and provided to facilitate ejecting a formedand tied bale. To accommodate different crop and fieldconditions, the Ramps can be mounted in either of fourlocations, using the holes provided. When baling certainwet crops, it may also be necessary to remove the Rampsto facilitate ejecting the bale.

WARNINGBales made with the Round Baler are LARGE,CYLINDRICAL and HEAVY! When ejected ona flat surface, the momentum of the bale, com-ing off the bale discharge ramps, could carrythe bale as far as 10 feet (3 m) behind the baler.On a hill or incline, this distance could bemuch farther. Serious personal injury or prop-erty damage could result if the bale is ejectedtoward a sloping surface and allowed to rollaway uncontrolled!

BALE STARTER (Figs. 52 & 53)The Bale Starter device is a set of Fingers that arelocated between the Belts and behind the PackingRoller. They deflect material and keep it from comingout over the top of and wrapping on the Packing Roller,when starting a bale. The Fingers are part of a movableassembly which is held by Pivoting Links and posi-tioned by a Roller. Springs on each side of the movableassembly return the assembly to a starting position aftereach bale is ejected. The Roller rides on the Belts and ispositioned by the bale.

IMPORTANT: Before starting to form each newbale, look back at the Baler to make sure the BaleStarter Assembly has returned to its startingposition. It is possible that material which iswedged in the Links and worn Pivot Bushings orbent linkages can cause the Starter to hang up.

NOTE: After Gate Stops have been adjusted, itmay also be necessary to readjust the Gate EndRoller position. Refer back to the Gate End Rollertopic in the next paragraph.

GATE END ROLLER (Fig. 58)

The Gate End Roller can be adjusted by means of the1/2″ Bolts (3 for 1475 or 2 for 1875) and (1) 5/16″ Bolton each side of the Gate. The 1/2″ Bolts are installed inslots and the 5/16″ Bolt can be positioned in any one ofa series of holes to vary the position of the Roller. TheRoller should be adjusted and maintained at a positionof 1/2 to 1″ (13 to 25 mm) from the 16″ Lower DriveRoller. This distance should be increased to 1 to 1-1/2″(25 to 38 mm) for Balers with the Quick Wrap.

NOTE: The Tailgate MUST be tight against thestops before making adjustment. (See Fig. 57)

IMPORTANT: BE SURE that the Roller is set tothe same position on both sides of the Gate, asdetermined by the 5/16″ Bolt pattern. Also, BESURE that the Right and Left Gate End RollerSupport Arms are kept parallel to each other toinsure proper Belt tracking.

OVERRUNNING CLUTCHSPROCKET (Fig. 59)The Scraper Roller Overrunning Clutch Sprocketassembly gives positive drive to the Roller whileallowing for slight differences in the Roller and Beltspeeds. To check for freedom of rotation, with the Balerempty, shuttle locks engaged, and Baler disconnectedfrom the tractor, use a 3/4″ wrench and rotate the capscrew clockwise. The Overrunning Clutch should rotatewithout rotating any of the other drives. The Clutch isa self-contained unit and can be removed by removingthe retaining cap screw.

NOTE: If the Clutch needs to be removed, blockGears on the opposite side of the Baler with a blockof wood.

PACKING ROLLER CLEARANCE(Figs. 59 & 62)The purpose of the Packing Roller is to compress thematerial which is entering between it and the 8″ LowerRoller. The Packing Roller is spring-loaded and drivenfrom the left side of the machine. Clearance between thelower 8″ Roller and the Packing Roller should be set at1/4″ (6 mm). This setting is made with the 1/2″ Bolts onthe end of the Packing Roller Roll Arms on both sidesof the Baler. This clearance should be checked on aroutine basis every 100 hours. The Packing RollerTension Spring lengths, on both sides of the machine,should be set to 9″ (229 mm). For lighter, fluffier crops,the clearance should be opened up and the spring tensionshould be reduced.

IMPORTANT: The Spring which places tensionon the Packing Roller is guided by a Rod with athreaded end. The threads are provided to enableSpring installation in a compressed state. Makesure that the Nut on the threaded Rod is NOTholding the Packing Roller open which could resultin damage to the Spring Bracket.

PICKUP (Fig. 60)

The Baler Pickup should be run as high off the groundas possible while still being able to completely pick upall of the crop. A Hand Crank is provided to raise andlower the Pickup. If a Hydraulic Lift Kit is installed, thelower limit of the Pickup is controlled by the HandCrank. To set clearance, lower the Hand Crank andHydraulic Lift Cylinder all the way. Set groundclearance with the manual Hand Crank. The Pickupheight can also be adjusted by repositioning the LiftRods (Fig. 63) into a different hole location. Thisadjustment may be required if the axle and HitchTongue have been positioned in the extreme higher orlower position.

NOTE: The Hand Crank setting overrides theHydraulic Lift Cylinder if the Lift Cylinder is re-tracted.

NOTE: The Pickup is raised by turning the HandCrank in a clockwise direction and lowered by turn-ing the Hand Crank in a counterclockwise direc-tion.

Overfill Clutch (Fig. 62)The Overfill Clutch mechanism is linked to the PickupDrive and serves to protect the Baler if it becomes filledbeyond design capacity. Readjustment of the Clutchmechanism may be required due to stretching of theV-Belt or Overfill Clutch linkage Cable. To make theadjustment, first make sure the Pickup is set to itsoperating height. Then, loosen the 3/8″ Hexagon Nutwhich clamps the Cable to the Pickup V-Belt Idler Arm.Pull on the Cable until the Idler moves and backs offslightly and then retighten the Nut.

Check to see if the Overfill Clutch linkage Cable is tooloose by pulling down on the Cable at the upper rear ofthe Baler. The Cable, when pulled down, should deflectdownward less than 2″ (51 mm) from the Frame channelbefore the Pickup V-Belt Idler has started to move away

from the V-Belt. If deflection is more than 2″ (51 mm),readjust Cable clamping point. Cable tension should bechecked on a routine basis every 50 hours of operation.

IMPORTANT: Excessive Cable tension willmean inadequate V-Belt tension and result inexcessive V-Belt wear and Pickup slippage. Toolittle Cable tension will cause the Overfill Clutch tomalfunction and thus NOT protect the Baler. Thefirst bale made, after the Overfill Clutchmechanism is adjusted, should be observed in itsfinal stages with a cautious eye to insure that themechanism is functioning properly.

WINDGUARD (Fig. 63)The Windguard for the Pickup has a Limit Stopadjustment. The Limit Stop adjustment consists of two5/8″ Hexagon Head Cap Screws located on either sideof the hitch frame. The Cap Screws are used to set theupper limits of Windguard travel. Normal settings willrestrict the Windguard Tines from being raised anyhigher than the center of the Packing Roller.

WARNINGNEVER operate the baler unless the wind-guard is in place and properly adjusted.

SCRAPER (Figs. 52 & 64)The Lower Drive (Scraper) Roller for the Belts isprovided with an adjustable full-width Scraper to helpprevent material build-up on the Roller. The ScraperMUST be set close to enable full-width cleaning. To



adjust the Scraper Blade, loosen the 5/16″ attachinghardware on the bottom of the Blade. Then, tap the Bladeinto contact with a 1/16″ (1.5 mm) piece of shim stockagainst the Roller. Then, tightly secure the 5/16″hardware. The Blade itself will wear and may requirereplacement after a period of extended Baler use.Contact your GEHL dealer for the replacement Bladepart number.

IMPORTANT: Inspect the Scraper adjustmenton a routine basis every 50 hours of operation. Ifthe Scraper is NOT adjusted correctly, material willbuild up on the Roller and cause excessivehorsepower requirements.

In certain short or very dry straws or grass conditions,bale starting may be improved by slackening the Beltsduring the core formation stage. The Shuttle Stops areprovided to enable slackening the Belts, when required.Rotate the Shuttle Stop Bolt on each end of the Shuttleassembly equally to move the Shuttle rearward. 1″(25 mm) of rearward Shuttle movement results inapproximately 4″ (102 mm) of slack in the Belts.

SQUARING BELT SHUTTLE(Figs. 62 & 65)It is essential that the Belt Shuttle be square with theBaler Frame and the Belt Tracking Roller be properlyadjusted (per topic titled “Belt Tracking & Alignment”)so that the Belts track evenly. To check for Shuttlesquareness, measure from a crossmember on the topfront of the Baler to the right and left end of one of theShuttle Roller Tubes. To square the Belt Shuttle, havethe Baler empty and the Rear Gate closed. Adjustsquareness with the Bolt on the left end of the Shuttle.If the Adjustment Bolt will NOT square the Belt Shuttle,it will be necessary to change the Index position of theKeyed Sprockets that connect the left and right DensityCylinder Loading Chains. Use the following procedurefor adjustment:

1. Determine the direction in which the CylinderLoading Chain needs to be adjusted. Rememberthat the two Sprockets for the Chain tension arekeyed to a common Shaft.

2. Depressurize the TDC system. Fully loosen or re-move the Valve Stem located on top of the Reser-voir. DO NOT retighten until ready to pressurize.

3. Remove the Trip Spacer from the Cylinder TripArm. This is done to prevent accidental actuationof the Valve Trip Mechanism (covered later in thischapter).

4. Advance the No. 60 Cylinder Loading Chain thenecessary amount and readjust belt to squareShuttle.

5. Replace and/or tighten Valve Stem and pressurizeto 140-150 PSI (980–1050 kPa).

6. Replace the Trip Spacer on the Trip Arm. Checkto make sure that it will contact the spring loadedValve Trip Mechanism when baling resumes.



TWINE TIE SYSTEM

Twine Placement (Figs. 66 & 67)

To adjust twine placement on the left-hand side of theBaler:

1. Extend the Actuator until the Twine Arm ap-proaches the left side.

2. Loosen the Jam Nut on the Stop Bolt located onthe left side of the Twine Tie Frame Assembly.

3. Extend the Stop Bolt to stop the Twine Arm closerto the center of the bale and retract the Stop Boltto allow the Twine arm to travel closer to the leftside of the bale.

4. Secure the adjustment by tightening the Jam Nut.

BALE FORMING BELTS

Tension Adjustment (Figs. 54 & 62)

The tension of the Belts and subsequent bale density iscontrolled by the hydraulic TDC system. Belt tensioncan be varied by changing the Relief Valve pressuresetting. Belt tension and bale density is increased byturning the Valve Cartridge End Disc clockwise into theCartridge.

When the Baler is manufactured, Belt tracking is set atthe factory. This setting, however, may require adjust-ment after the paint is worn off and the Belts are brokenin. After the Baler has made at least 50 bales, adjust Belttracking in the following manner:

1. Make sure Shuttle is square and Tailgate is closedand latched. Take note first, as the bale is forming,if all of the Belts tend to travel to one side. If theydo, form the next bale to about half-size and stopbaling. After exercising the MANDATORYSAFETY SHUTDOWN PROCEDURE (page10), reposition the Belt Tracking Roller. Makesure that, before proceeding, the half-size bale isuniform and NOT barrel or cone-shaped. Then, bya test and readjust process, reposition the TrackingRoller until all of the Belts are NO longer rubbingon the Belt Guides; lowering the right side of theRoller will cause the Belts to travel to the left. Af-ter each 1/8″ (3 mm) of Roller repositioning ismade, tighten the Retainer hardware and watchhow the Belts are tracking through at least 3 com-plete revolutions of the belts before stopping op-eration and continuing to readjust the Roller posi-tion.



2. Interchanging Belt positions may also improveBelt tracking. This process, however, is somewhatmore difficult since it requires removing the Beltsfrom the Baler in order to change Belt positionsrouted through the Belt Guide and around ap-propriate Rollers.

NOTE: Improper bale formation may give an er-roneous indication of faulty belt tracking. See “BaleFormation” topic in the Operation chapter for de-tails.

NOTE: Whenever Belt Lacings are uncoupled,BE SURE to re–couple the Belt so the end with ex-tra Hooks stays on the leading end as illustrated.

Rear Gate Belt Guide(Figs. 70, 73 & 74)

To help improve Belt tracking, both model Balers areprovided with a Rear Gate Belt Guide. The mountingposition of the 1475 Belt Guide is fixed (non-adjust-able). The 1875 Belt Guide is mounted in slotted holes.Therefore, the Belt Guide can be adjusted and securedin a position from 1/16 to 1/4″ (1.5–6 mm) away fromthe Belts as shown.

AUTOMATIC TWINE WRAP SYSTEMSWITCH ADJUSTMENTS

Bale Size Adjustment (AfterSN25000–1475 & SN17900–1875)(Fig. 75)While a bale is forming in the bale chamber, the ShuttleChain (4) causes the Cylinder Rod (3) to extend. As thebale approaches full size, the Magnet (2) comes close tothe Sensor Assembly (1). This closes the Sensor Switchcontacts and starts the bale tie sequence.

The size of the bale is determined by the position of theMagnet in the slotted Bracket (5). To make largerdiameter bales, loosen the Knurled Nut on the Magnetand slide the Magnet downward in the slot. Then tightenthe Nut.

2. Disconnect the Pause Switch from the Wiring Har-ness at the Connector (4). Then, using an ohmmeter(or equivalent), check the Switch continuity byplacing the test leads across the Connector termi-nals. Whenever the Magnet is close to the Switch,the Switch should close (have continuity).

Righthand End Wrap TwinePlacement Adjustment

1. Switch to “MANUAL” mode and extend the TwineArm until it is at the desired location for applyingtwine to the righthand side of the bale.

2. Disconnect the Pause Switch from the Wiring Har-ness at the Connector (Fig. 84, Ref. 4). Using anohmmeter (or equivalent), check the Switch conti-nuity by placing the test leads across the Connectorterminals.

3. Loosen the hardware (Fig. 85, Ref. 1) which se-cures the Trip Bracket (Ref. 2) to the Twine Arm.

4. Slide the Trip Bracket away from the Switch As-sembly so that the Switch is “closed” (has continu-ity).

5. Slowly slide the Trip Bracket toward the Push Le-ver (Ref. 3) until the Lever raises and the Switchjust “opens” (has no continuity). Then, tighten thehardware which secures the Trip Bracket to theTwine Arm.

This is the setting that will cause the the Twine Arm torepeatedly pause and apply end wraps to the right sideof the bale. To check this adjustment, proceed asfollows:

6. Switch to “MANUAL” mode and extend the TwineArm until it is beyond the desired End Wrap posi-tion.



7. Disconnect the Pause Switch from the Wiring Har-ness at the Connector (Fig. 84, Ref. 4). Using anohmmeter (or equivalent), check the Switch conti-nuity by placing the test leads across the Connectorterminals. The Switch should be “closed” (havecontinuity).

8. Retract the Twine Arm (move it toward the HOMEposition) until the Switch just “opens” (has no con-tinuity). The Twine Arm should now be at the de-sired position for applying the right End Wraps. Ifit is NOT correct, repeat Steps 1 through 5.

When the shuttle is fully returned and the TDC cylindersare retracted, the Shuttle Return Magnet must beadjusted so that the Magnet is centered opposite of theSensor Assembly. To adjust, loosen the Knurled Nut onthe Magnet and slide the Magnet opposite the Sensor inthe slot. Then tighten the Nut.

NOTE: As the belts stretch, the TDC cylindersshould be able to retract further without being re-stricted by the Shuttle Return Magnet Assembly.Additional adjustment may be required.

While a bale is forming in the bale chamber, the ShuttleChain causes the Cylinder Rod to extend. As the baleapproaches full size, the Overfill Magnet comes close tothe Sensor Assembly and closes the Sensor Switchcontacts and starts the wrapping cycle. The Magnet isdesigned to only act as overfill protection as bale size isgoverned by the Bale Size Sensor (see Fig. 83). TheOverfill Magnet Assembly should be adjusted so thatthe wrapping system will start before the Pickupdeclutches. This setting is nominally set at the factory to16-1/4″ (413 mm) for the 1475 and 22-1/2″ (572 mm)for the 1875 between the Overfill Magnet Assembly andthe Shuttle Return Switch. Driving conditions and cropconditions may require adjusting this setting to time thewrapping system ahead of the Pickup Declutch.

The Magnet is adjusted by its placement in the slottedSlide. To make larger diameter bales, loosen theKnurled Nut on the Overfill Magnet and slide theMagnet downward in the slot. Then tighten the Nut.

Shuttle Return Switch (Fig. 89)(Before SN25001-1475 &SN17901-1875)When the shuttle is fully returned and the TDC cylindersare retracted, the Clamp/Magnet Assembly must be sliddown the square tube until tight against the ShuttleReturn Switch Assembly. The Clamp/Magnet Assem-bly should be tightened onto the tube so that it can be slidalong the tube with 4 lbs. of force, but not vibrate or slidedown the tube while the TDC cylinder is extended.

NOTE: As the belts stretch, the TDC cylindersshould be able to retract further without being re-stricted by the Clamp/Magnet Assembly.

The Spacer Magnet Assembly is designed to start thewrapping system at the maximum bale size conditionand act as an overfill protection. The Spacer MagnetAssembly should be adjusted so that the wrappingsystem will start before the Pickup declutches. Thissetting is nominally set at the factory to 16-1/4″ (413

mm) for the 1475 and 22-1/2″ (572 mm) for the 1875between the Spacer Magnet Assembly and the ShuttleReturn Switch. Driving conditions and crop conditionsmay require adjusting this setting to time the wrappingsystem ahead of the Pickup Declutch.

To adjust, loosen the set screws in the set collar and slidethe set collar, compression springs, and the SpacerMagnet Assembly up or down the tube to the desiredposition and retighten set screw. Sliding the parts towardthe Switch Assembly will advance the start of thewrapping mode and away from the switch will delay thewrapping mode.

QUICK WRAP ADJUSTMENTS

Drive Roller Chain (Fig. 90)Occasionally, it may be necessary to readjust the twoDrive Roller Chains on the left-hand side of the PinchRollers and Knife assembly. Proceed as follows:

1. Loosen mounting hardware on Double SprocketIdler Bracket.

2. Adjust the tension of the Inner Chain (Knife as-sembly to Double Sprocket Idler) first by slidingthe Idler away (outward in the slots in End Pan-el).

3. Keeping the Inner Chain taut, rotate the Idler in aclockwise direction to tension the Outer Chain(Double Sprocket to Pinch Roller). Retighten themounting hardware.

Pinch Roller Mechanism(See Figs. 43 & 44)

The pressure on the Pinch Drive Roller against the IdlerRoller is adjusted by the Compression Spring andAdjusting Bolt on each side. Starting with the AdjustingBolt loose, set the pressure by equally tightening bothAdjusting Bolts just enough to allow rotation of the Idler(Steel) Roller. Equal pressure should be maintained onboth sides by measuring the Spring compressed dis-tance. This distance should be maintained at 1-3/4 to1-7/8″ (44 to 46 mm).

Feeder Belt Tension & Tracking(Figs. 91, 92 & 93)

NOTE: With different wrap materials in differentconditions, it may be necessary to increase the dis-tance between the Guides and Roller.

The Wrap Feeder Belts are preadjusted at the factory.Readjustment may be required after break-in has oc-curred. The Feeder Belts are friction-driven by the Baler(bale forming) Belts. BE SURE that the Baler Belts aretracking correctly. Refer to the Tracking & Alignmentsection in this chapter for additional information.

The Wrap Feeder Belt tension and tracking may beadjusted by repositioning the Idler Roller (See Item 1,Fig. 91). Loosen the mounting bolt in the ends of theIdler Roller. Using a suitable prying mechanism, tightenthe Feeder Belts equally on each side by moving the idlerrolled downward and retighten the mounting bolts.

Enough tension MUST be maintained in the Feeder Beltsto make the Belts track properly and prevent relativeslippage with the Baler (bale forming) Belts.

Operate the Baler and check the Belt tracking with theTailgate closed and locked. The Feeder Belts should beadjusted to track straight with minimal rubbing on theGuides while following the Baler (bale forming) Beltsrelatively close. Lowering the right side of the Rollerwill cause the Belts to travel to the left.

If the Feeder Belts still do NOT track satisfactorily, itwill be necessary to adjust the top Feeder Roller (SeeItem 1, Fig. 93). Start by loosening the idler roller andallow the Belts to go slack on both sides. The top FeederBelt Roller Shaft should be parallel with the Baler BeltTracking Roller before making the initial adjustmentfor Feeder Belt tracking. When doing the trackingadjustment, lowering the right side of the top FeederRoller will cause the Belt to track to the right. Usually,sliding the top Roller 1/8 to 1/4″ (3 to 6 mm) is anadequate adjustment. Proceed by tightening the LowerIdler Roller as outlined earlier in this section.

Feeder Belt Fingers (Figs. 94 & 95)

The Feeder Belt Fingers are provided to guide the Netting.In their positions next to the Lower Feeder Belt Roller, theFingers must not contact the sides of the belt. Heating ofthe guides by belt contact will melt the net as it is pulledtowards the bale. Also, in this area, the Fingers strip theNetting from the Feeder Belts. As the Netting is broughtalong by the (bale forming) Belts, the Fingers guide theNetting toward the bale, in the area of the Tailgate Roller.The Fingers should always be adjusted to and maintainedat a distance of 1/4″ (6 mm) away from the Rollers in bothpositions.

NOTE: BE SURE to check that all of the Fingersare secured on the left side of their respectiveMounting Tabs.

Brake (Net) Tension(Figs. 96, 97 & 98)The Quick Wrap Net tension is established and con-trolled by the Brake Tension on the right side of theQuick Wrap unit. To properly adjust the Brake andsubsequent Net tension, proceed as follows:

NOTE: Brake tension adjustment regulates theamount of Quick Wrap Net tension on the bale. Es-tablishing a measured tension of 130 to 160 in-lb(15 to 18 Nm) on the Rubber Drive Roller, with atorque wrench, will provide the correct amount ofNet tension. Too much tension will prevent the Netstarting onto the bale. Too little tension will causethe Net to be wrapped too loosely causing poorweathering and crop loss.

1. Fully extend the Actuator.

2. Adjust the Washer assembly on the Strap so theBushing will catch in the detent, just as the Actua-tor is fully extended. BE SURE the Bushing is freeto rotate on its mounting Bolt (See Item 2, Fig. 97).

3. Using the Set Screw and Jam Nut on the side of theBrake Caliper, adjust the Activation Arm so it isperpendicular to the Caliper Housing (Fig. 97).

4. Adjust the Spring length to 2–1/6″ (52 mm)(Fig. 96).

5. Manually retract the Actuator. As the Actuator isretracted, the Strap assembly should hold the Piv-ot Assembly still and prevent it from rotating withthe Actuator. (This maintains the same Brake ten-sion as when the Actuator is fully extended.)



6. Cycle the Actuator to make sure that the Strap iscatching the Detent at full Actuator extension.

7. Use a torque wrench to check the torque readingon the Rubber Drive Roller. The torque should be130-160 in-lb (15 to 18 Nm), when the Brake isfully applied. If the torque is NOT correct, adjustthe Spring length to obtain a reading of 130-160in-lb (15 to 18 Nm), to rotate the Rubber DriveRoller (Fig. 98).

8. Retract the Actuator to make sure that the Strap,catching the Detent, is releasing properly. Whenthe Actuator is approximately 2/3 fully retracted,the Washer (on end of Actuator Rod) should dis-engage the Strap assembly from the “detent” posi-tion and release the Brake.

NOTE: Drive Rollers should be able to be ro-tated by hand when Actuator is retracted.

CHAPTER 8LUBRICATION

GENERAL INFORMATION

WARNINGNEVER lubricate the machine when any partof the unit is in motion. ALWAYS exercise theMANDATORY SAFETY SHUTDOWN PROCE-DURE (page 10), BEFORE lubricating the ma-chine.

It is well to remember that a sufficient amount of oil orgrease will prevent excessive part wear and earlyfailure.

IMPORTANT: Whenever service is performedon hydraulic components (valves, cylinders,hoses, etc.) or Transmission, care must be takento prevent discharging fluid onto the ground.Catch and dispose of fluid per local waste disposalregulations.

TRANSMISSION LUBRICATION

The Transmission should be checked after every 100hours of operation and the oil level replenished asnecessary. The Transmission requires 1 quart (.95 liters)of SAE 80W90 EP Gear Lube.

The Transmission should be checked occasionally foroil drips and dust accumulation which indicates theSeals are leaking. Oil which is tan in color and foamsexcessively indicates that it has water present andshould be replaced.

The Transmission is drained by removing the lowerPlug on the Transmission or Dipstick pipe tee. All plugsare located on the right side of the Transmission and areaccessed beneath the Baler Cross Frame. Fill Transmis-sion with the proper type and amount of oil or until oilappears at the oil check hole or the proper mark on theDipstick. Replace all Plugs.

IMPORTANT: Do NOT overfill the Transmission.Only fill it to the bottom of the Inspection Plug holeor to the mark on the Dipstick (for those modelswith Dipsticks).

TDC HYDRAULICS SYSTEMMaintain the fluid level in the Sight Tube at NO higherthan the upper oil level Decal mark on the Reservoirwith the Density Cylinders fully retracted. The TDCsystem comes primed from the factory with a specialgrade of hydraulic oil capable of operating at lowerambient temperatures than normal hydraulic oils. If lowtemperatures and slow shuttle returns are not a problem,ATF (Dexron II) is an acceptable oil to use in the TDCsystem. During the baling season, the fluid level shouldbe checked before each day of operation (or at least onceevery 10 hours) and replenished if the fluid drops belowthe lower oil level decal mark with the DensityCylinders fully retracted.

OILINGLubricate all Drive Chains every 10 hours (or daily) ofoperation using a clean oil or a good grade of foamingaerosol lubricant. The recommended method is to spraythe entire length of Chain on the center of the Rollerssufficiently to allow the chain sidebars to be thoroughlylubricated. It is better to lubricate Chains when they arewarm (after use, rather than before).

NOTE: For a Baler equipped with an accessoryAutomatic Chain Oiler, fill the Oil Reservoir Tank asoften as necessary with a good grade of clean pe-troleum oil (SAE 20-40). Usually, a full Tank shouldprovide adequate lubrication for producing100-150 bales.

Apply oil or foaming aerosol lubricant to the threads ofthe Pickup Height Adjustment Crank every 100 hours(or monthly).

Apply oil or foaming aerosol lubricant on all BaleStarter Pivot Bushings at the end of each baling seasonor before storing Baler. Best results are obtained if oil isapplied at the end of day or when Bushings are warm.

IMPORTANT: Remove any stems or leaveswhich might be wrapped around shafts next toBearings. Wrapped debris buildup can bedamaging to the Bearing Seals.

GREASINGNOTE: Grease all fittings on a prescribed basis,at the intervals of operation listed, before and afterstoring the unit, and as otherwise indicated. Use agood grade of Lithium base grease.

Chapter 8 – Lubrication


Wipe dirt from the fittings before greasing to prevent thedirt from being forced into the Bearing or Pivot. Replaceany missing fittings, when noted. Force the grease intothe fitting until it comes out at the Bearing Seal or at theShaft. To minimize dirt buildup, avoid excessivegreasing.

IMPORTANT: In addition to the fittings, inspectand repack the Wheel Bearings at least once aseason. The Telescoping PTO Drive should alsobe separated and grease applied to the splines atleast three times during the harvesting season.Apply a light coat of grease on the Twine Knifefollowing each season and before placing the Balerinto storage.

QUICK WRAP LUBRICATIONThe Drive Roller Chains should be lubricated every 100hours using a good grade of foaming aerosol lubricant.The recommended method is to spray the entire lengthof Chain on the center of the Rollers sufficiently to allowthe chain sidebars to be thoroughly lubricated.

The only other required lubrication on the Quick Wrapunit is to apply oil or foaming aerosol lubricant to thevarious hinge or pivot points annually.

CHAPTER 9SERVICE

WARNINGBEFORE Servicing this unit, exercise theMANDATORY SAFETY SHUTDOWN PROCE-DURE (page 10).

NOTE: The following information is referred toin both the Troubleshooting Guide and the Mainte-nance Schedule chapters of this manual. It shouldalso be understood that all services covered in thischapter are Owner-Operator responsibilities.Where indicated, certain service routines shouldonly be carried out by an authorized GEHL Dealeror GEHL Company representative.

SEALED BALL BEARINGREPLACEMENT (Fig. 99)

Sealed Ball Bearings are used on various Shafts aroundthe unit. This type of Bearing is generally retained inplace with a Self-locking Eccentric Collar. The LockCollar has a counter bored recess, which is eccentricwith the Collar bore. This eccentric recess engages ormates with an eccentric end of the Bearing inner ring,when the Bearing is assembled on the Shaft. TheBearing is engaged, on the inner ring cam, by the Collar.This assembly grips the Shaft tightly with a positivebinding action that increases with use. The Collar SetScrew provides supplementary locking.

A Bearing can be removed from the Shaft by looseningthe Set Screw and tapping on a punch which is placed inthe drift pin hole, to loosen the Collar. Install Bearingswith self-locking Collars in the following manner:

1. Place the Bearing and Collar on the Shaft with thecam surfaces next to each other. Tighten the boltson the Bearing Retainers.

2. Mate the cam of the Lock Collar with the cam ofthe Bearing inner ring.

3. Press the Locking Collar against the Bearing wideinner ring and turn it, in the direction of Shaft rota-tion, until it tightly engages. Tighten the Collarfurther by tapping on a punch inserted in the driftpin hole.

NOTE: Avoid damaging the Collar by overtigh-tening it.

4. Last, tighten the Set Screw in the Locking Collar.

TOTAL DENSITY CONTROL(TDC) SYSTEM

WARNINGNEVER use your hands to search for hydrau-lic fluid leaks. Escaping fluid under pressurecan be invisible and penetrate your skin caus-ing serious injury! If any fluid is injected intoyour skin, see a doctor at once! Injected fluidMUST be surgically removed by a doctor fa-miliar with this type of injury or gangrene mayresult.

Reservoir Air Pressure (Fig. 105)

The TDC system comes primed from the factory with aspecial grade of hydraulic oil capable of operating atlower ambient temperatures than normal hydraulic oils.If low temperatures and slow shuttle returns are not aproblem, ATF (Dexron II) is an acceptable oil to use inthe TDC system. The system is to be pressurized to 150PSI (1050 kPa) by air pressure in the Reservoir. Fornormal operation, the Reservoir Pressure Gauge MUST



indicate a pressure reading of 140 to 150 PSI (980-1050kPa). If the reading is NOT within this range, either addAIR or bleed off AIR, as necessary, using the Tank Inletand Valve Stem at the top of the Reservoir.

WARNINGDO NOT pressurize the Reservoir to morethan 150 PSIG (1050 kPa) when adding air andNEVER pressurize with anything other thanAIR!

NOTE: When operating this machine duringtimes of extreme cold ambient temperatures and ifa faster shuttle return speed is desired, use only oilsupplied by Gehl in the TDC System. Refer to the“Draining and Repriming System” later in thisChapter for the proper draining procedure.

Reservoir (Fig. 105)The Reservoir fluid level should be checked before eachday of Baler operation (or at regular 10 hour intervals)using the Sight Tube located on the forward side of theReservoir. Proper fluid level can be determined whenboth Density Cylinders are fully retracted. In thiscondition, the level of fluid in the Sight Tube should beslightly below the level mark Decal.

NOTE: If the fluid level is below the bottom 1″(25 mm) level mark, add fluid BEFORE attemptingto operate the Baler. Refer to the “Adding Fluid toReservoir” topic below for proper refilling proce-dures.

WARNINGDO NOT remove any hydraulic lines or fittingsuntil you are sure that the system is depressu-rized and that there is no load on any hydrau-lic components. Failure to heed may result inpersonal injury.

Adding Fluid to Reservoir (Fig. 105)

WARNINGNEVER contaminate the reservoir fluid withany flammable liquid. ONLY use non-flam-mable cleaning solvents for cleaning compo-nents or containers used for storing, trans-porting or transferring the fluid. If the fluidshould become contaminated with a flam-mable liquid, the resulting mixture, whencombined with compressed air, can explodecausing death or serious injury.

To add fluid to the TDC System Reservoir, proceed asfollows:

1. Make sure TDC cylinders are fully retracted (Bal-er empty and tailgate closed and latched).

2. Clean the top of the Reservoir to prevent any con-tamination during draining or refilling.

3. Fully depressurize the system by loosening or re-moving (and retaining) the Valve Stem from theInlet at the top of the Reservoir.



4. Remove and retain the Relief Valve Adapter fromthe top of the Reservoir.

5. The TDC system comes primed from the factorywith a special grade of hydraulic oil capable of op-erating at lower ambient temperatures than nor-mal hydraulic oils. If low temperatures and slowshuttle returns are not a problem, ATF (Dexron II)is an acceptable oil to use in the TDC system. Addthe necessary amount of fluid through the ReliefValve Adapter opening to bring the level in theSight Tube in line with the lower level mark on theTDC Reservoir (both Density Cylinders MUSTbe fully retracted when using the lower levelmark).

6. After the proper amount of fluid has been added,reinstall and secure Relief Valve Adapter (andValve Stem, if removed) at top of the Reservoir.

7. Using AIR pressure ONLY, repressurize the sys-tem to 140-150 PSI (980-1050 kPa).

If the system has air in it (or gets air into it from openinga hydraulic line), it MUST be reprimed. Or, if the systemrequires complete draining (to change to a lighter orheavier fluid, for example), refer to the “SystemDraining and Repriming Procedure” for details.

System Draining and ReprimingProcedures (Fig. 105)1. Make sure TDC cylinders are fully retracted (Bal-

er empty and tailgate closed and latched).

2. Clean the top of the Reservoir to prevent any con-tamination during draining or refilling.

3. Fully depressurize the system by loosening or re-moving (and retaining) the Valve Stem from theInlet at the top of the Reservoir.

4. Remove and retain the Hardware securing the TripSpacer to the Trip Arm for the right side DensityCylinder and remove the Trip Spacer. This MUSTbe done to prevent accidental activation of theValve Trip Mechanism.

5. Fully extend both Density Cylinders by pulling onthe Belts at the back of the Baler (this will pull theShuttles back and extend the Cylinders) and thenblock them in the extended position so they willNOT retract.

6. Check the fluid level in the Reservoir. With bothDensity Cylinders fully extended, the fluid levelshould be in line with or slightly above the upperlevel mark on the Reservoir. If fluid has to be add-ed, go to Step 9.

If the fluid is going to be drained and replaced,continue with Step 7. If repriming is all that is required,go to Step 9.

7. Place a 2 gallon or larger container near the rightside Density Cylinder to catch the fluid duringdraining. Disconnect the TDC Reservoir Hydrau-lic Hose at the Manifold Disconnect and allow thefluid to drain into the container.

IMPORTANT: Whenever service is performedon hydraulic components (valves, cylinders,hoses, etc.), care must be taken to preventdischarging fluid onto the ground. Catch anddispose of fluid per local waste disposalregulations.

8. After draining is completed, reconnect the Hy-draulic Hose at the Manifold Disconnect.

9. Remove and retain the Relief Valve Adapter fromthe top of the Reservoir.

10. The TDC system comes primed from the factorywith a special grade of hydraulic oil capable of op-erating at lower ambient temperatures than nor-mal hydraulic oils. If low temperatures and slowshuttle returns are not a problem, ATF (Dexron II)is an acceptable oil to use in the TDC system. Addthe necessary amount of fluid through the ReliefValve Adapter opening to bring the level in theSight Tube in line with the upper level mark on theTDC Reservoir (both Density Cylinders MUSTbe fully extended when using the upper levelmark).

11. After the proper amount of fluid has been added,reinstall and secure Relief Valve Adapter (andValve Stem, if removed) at top of the Reservoir.

12. Check the Belts to MAKE SURE that they areNOT twisted and remove any blocking used tohold the Density Cylinders in the extended posi-tion.

13. Using AIR pressure ONLY, repressurize the sys-tem to 140-150 PSI (980-1050 kPa). Repressuriz-ing the Reservoir forces oil through the hydrauliclines and retracts the Density Cylinders.

14. Bleed any air that may have entered the DensityCylinders by carefully opening the Bleed Valve atthe top of each Density Cylinder.

NOTE: It may be necessary to repeat steps 3.,9., 10., 11., 12. and 13. several times in order tocompletely bleed the air from the Density Cylin-ders.



15. Reinstall the Trip Spacer and secure it to the TripArm. MAKE SURE that the Trip Spacer properlycontacts the Valve Trip Mechanism before resum-ing baling.

Pressure Relief Valve(Figs. 105 & 106)Faulty Valve OperationMalfunction of the Adjustable Pressure Relief Valve issuspected if one or more of the following conditionsarise while baling:

1. If desired density bale can NOT be produced, con-tamination may be keeping the Relief Valve Pop-pet from seating properly. To test this: first, fullydepressurize the system by loosening or removing(and retaining) the Valve Stem from the Inlet at thetop of the Reservoir. Then, remove the Pipe Plugfrom the top of the Adjustable Relief Valve Man-ifold and in its place, install a 1000 PSI (7000 kPa)MINIMUM pressure gauge. Next, loosen theLocking Ring on the Adjustable Relief Valve (turnit counterclockwise) and then, gently turn the EndDisc clockwise until it bottoms. Now, remove theTrip Spacer and rotate the Valve Trip Mechanismclockwise to its upper stop position. Make surethat there is sufficient fluid in the Reservoir andthen open the Gate to extend the Density Cylin-ders. The indicated pressure on the pressure gauge(installed above) MUST be at least 500 PSI (3500kPa), otherwise the Relief Valve Poppet is NOTseating properly.

2. If the Density Cylinders will NOT retract quickly,contamination may be blocking the Check Valveand preventing the hydraulic oil from flowingfreely through the Valve. To check this, turn theValve Trip Mechanism to its counterclockwisestop position when the Density Cylinders are ex-tended. If the Cylinders quickly retract, the CheckValve is malfunctioning.

3. If excess power is required for baling or if frequentBelt failure is experienced, contamination may beblocking the Relief Valve Poppet, thereby pre-venting free flow of fluid through the Valve. Totest this, use the same test procedures as for Step1 above and if the gauge reading rises above 700PSI (4900kPa), the Relief Valve may be blocked.

If any or all of the above situations occur, the PressureRelief Valve can be partially disassembled followingdetails in the next topic.

Relief Valve Removal & Replacement

If the Adjustable Pressure Relief Valve is suspected ofleaking or blockage, it can be partially disassembled inthe following manner:

WARNINGDO NOT remove any hydraulic lines, fittingsor components until you are sure that the sys-tem is depressurized and that there is no loadon any hydraulic components. Failure to heedmay result in personal injury. To fully depres-surize the system, loosen or remove (and re-tain) the valve stem from the inlet at the top ofthe reservoir (see Ref. 2, Fig. 108).

1. MAKE SURE the system is depressurized. Also,MAKE SURE the Density Cylinders are fully re-tracted and there is NO bale in the machine.

2. Carefully disconnect the Reservoir-to-ManifoldHose at the Manifold Disconnect Coupler.

3. Remove and retain all but one of the four ManifoldBracket mounting bolts so the Manifold assemblycan be swung clockwise as far as the Hose connec-tions will allow and temporarily secured (with theremaining screw). The Manifold should be rotatedto avoid excessive fluid loss.

IMPORTANT: Whenever service is performedon hydraulic components (valves, cylinders,hoses, etc.), care must be taken to preventdischarging fluid onto the ground. Catch anddispose of fluid per local waste disposalregulations.

WARNINGBE SURE to wear a face and eye protectionshield or goggles and position yourself sothat your face is away from the valve to pre-vent contact with the escaping fluid.

4. Carefully loosen the Adjustable Relief Valve andbleed off pressure from the system.

5. After pressure has been removed, the Valve can beremoved from the Manifold and the openingshould be plugged to prevent contamination.

6. Inspect the Cartridge for a leaky or blocked Pop-pet. Force the Poppet on the front end of the Car-tridge backward and, using a clean punch, rotatethe Poppet to dislodge any contamination.

7. After step 5 has been performed, check the twooutside O-rings for damage and then replace theCartridge into the Manifold.

8. With the Cartridge replaced, reattach the Man-ifold assembly into its original mounting positionand secure it.

9. Carefully and properly reconnect Quick coupler.

10. Check the Reservoir fluid level and pressurize to140-150 PSIG (980-1050 kPa) before attemptingto resume operation.

NOTE: If the Baler fails to operate properlyafter the above procedures have been carried out,contact your dealer for further directives. To orderreplacement Valve Cartridge, specify GEHL part#094191 (1475) and 127112 (1875).

To repair Cartridge specify GEHL part #094193 for SealKit. Replace Check Valve with part #119302.

TRANSMISSIONIMPORTANT: Internal Transmission componentrepairs and replacements should only beattempted by (or under the direction of) anauthorized GEHL equipment dealer.

To remove Transmission for service, proceed as follows:

1. Remove Windguard Assembly.

2. Remove Twine Tie System (5 bolts, 1 electricalconnection on Manual Tie, 2 electrical connec-tions on Auto-Electric models).

3. Release Drive Chain tension, break the DriveChain and loosen the Bearing attaching hardware.

4. Loosen 4 flangette mounting bolts on cross shaft.

5. Slide cross shaft off of transmission output shaft.

6. Remove the (4) fasteners securing the Transmis-sion Housing to the Crosstube.

7. Carefully remove the Transmission from the unit.

After service is performed, replace the Transmission inreverse order of removal. Then, replace the oil until itcomes out the Inspection Hole or reaches the full markon the Dipstick. The Transmission requires 3 U.S. pintsof SAE 80W90EP Gear Lube. Replace and readjust theDrive Chain.

Belt Tension (Fig. 108)If the Belts do NOT return or otherwise are NOTreturning fast enough after ejecting a bale, check out thefollowing items in the order listed to troubleshoot andcorrect the problem.

1. Check the Gauge pressure for the Reservoir whilethe Baler is empty. If the pressure reads less than140-150 PSI (980-1050 kPa), add air to bring thepressure up to 140-150 PSI (980-1050 kPa). If thepressure drops again after a short time, there ismost likely a leak at one of the fitting connections.To find the leak, apply a soapy water solution tothe fittings and watch for air bubbles to form. Asnecessary, tighten the fitting connection or replacethe fitting. Be careful NOT to overtighten the fit-tings and damage the threads.

2. Check the Reservoir hydraulic fluid level. Withthe Cylinders fully retracted, the fluid should bebetween 1″ (25 mm) from the bottom of the Reser-voir to just below the Oil Level Decal mark. Referto TDC System topic in this chapter under Reser-voir subtopic for additional information.

3. Check the plumbing arrangement and compareyour machine to the routing shown in the TDCHydraulic Circuit Diagram provided.

4. Check the operation of the Pressure Relief Valvefollowing details under the Pressure Relief Valvesubtopic contained within the TDC System in-formation in this chapter.

5. Check for sticking Density Cylinders. Release theReservoir air pressure. Remove the Trip Spacerfrom the Trip Arm and then fully extend both Den-sity Cylinders by pulling the Belts at the back ofthe Baler. Slowly pressurize the Reservoir to 25PSI (75 kPa). Cylinders should retract completelyand smoothly.

Cause of Belt FailureWhen a Belt fails, it will usually occur in the area ofLacing Hooks and will be caused by one or more of thefollowing:

1. Bale improperly formed.

2. Lacing wire worn or broken.

3. Belt not properly laced.

4. Belts not tracking properly.

5. Build-up on Roller(s) or Scraper.

6. Baling when conditions are too wet.

Splicing and Re–lacing (Fig. 109)

Belts are laced with #4-1/2HT Clipper Lacing Hooksand 3/32″ diameter Nylon-coated Cable. These materi-als and a 6″ (152 mm) Vice Lacer can be obtained asservice accessories; see the Optional Features & Acces-sories chapter of this manual.

To relace a Belt, the following additional items will beneeded: small square, ball–point pen, sharp knife,long-nose pliers, slip-joint pliers and a vice.

To re–lace a Belt, follow the procedure below:

1. Open the Rear Gate, engage the Shuttle Locksand completely close Gate to remove Belt tension.Then remove the Belt to be re–laced.

2. Mark the Belt with the small square and ball–pointpen just behind the old hooks or 5/8″ (16 mm)from the end of the Belt. Carefully cut the Beltwith a sharp knife. Check the squareness fromboth sides after cutting. Clip the corners as shown.

NOTE: Relace both ends of a pulled lacing joint.By limiting the amount of Belt cut to 5/8″ (16 mm)on each end, a Belt can be re–laced twice beforealternative action is required; see Maintaining BeltLength section for details.

3. Install #4-1/2HT Hooks with the Vice Lacer.Make sure the ends of the Hooks protrude throughthe Belt and are clinched over.

4. Make sure outside Hooks are on the leading Beltend. Install relaced Belt in the Baler.

5. Cut an 8″ (203 mm) long piece of Nylon-coatedCable. Bend a 3/4″ (19 mm) loop in one end of theCable. Install Cable in splice positioning loop asshown.

6. Restore Belt tension by opening the Rear Gate andreturning the Shuttle Locks to storage.

7. Using the long-nose pliers, trim and bend the re-maining end of the Cable into a loop with a mini-mum of 3/4″ (19 mm) engagement into the lacing.

NOTE: To keep the belt splice in good operatingcondition, it is recommended that the LacingCables be replaced every 500 bales.

Maintaining Belt Length

The length of the Belts should be maintained within2-1/2″ (63.5 mm). This 2-1/2″ (63.5 mm) differencebetween Belt lengths can be achieved in either of twoways:

a. by switching Belts around to different posi-tions, or

b. by using Dutchman Splices.

a) Switching Belts

The lacing on the outside Belts is more likely to failbefore the inside Belt lacing. Outside Belts that havealready been relaced can be switched towards the centerof the Baler where less stress will be placed on thelacing.

NOTE: This practice of switching is the recom-mended procedure for purposes of expense andrepair time reduction.

b) Dutchman Splice

The original or matching Belt length can be restored byusing a Dutchman Splice on a Belt which has beenshortened excessively by repeated re–lacings, a diago-nal cut or a tear.

NOTE: It is important to keep an accurate re-cord of re–lacing for each Belt so that a Belt can bere–laced twice before the Belt is switched or aDutchman is necessary.

Dutchman Splice InstallationNOTE: The Dutchman Splice MUST be at least12″ (305 mm) in Belt length for ample lacing sepa-ration. If Lacings are staged too close together, theBelt Lacings will fail quicker. BE SURE to use thelongest Dutchman available as the piece that willbe cut off. The long Belt will (hopefully) be goodenough for more than 1 foot and then itself be us-able as a Dutchman. Refer to the Optional Fea-tures & Accessories chapter for Dutchmans avail-able.

RB1475 Belt (Fig. 110)Perform the following steps to restore a short or tornRB1475 Belt:

1. Cut one end off the long Belt as close to the dam-aged area as possible and without including thedamaged area. Relace this end.

2. Determine what overall length of Belt has to bedeveloped (Belt length only, NOT including Lac-ing). To determine the overall length, consider thefollowing:

a. A new Belt is 469″ (11 913 mm) long.

b. Belts should be maintained within 2-1/2″(63.5 mm) of each other.

c. Check your records as the Belt may alreadyhave been reduced in length due to previousLacing failures.

3. After the overall length required has been deter-mined, subtract the following:

a. Dutchman belt length

b. Extra gap necessary of 1/2″ (13 mm)

4. After the above measurements and calculationsare made, cut the long Belt to the appropriatelength determined and re–lace it.

5. Install the Cable Lacing Pin in one joint, reas-semble the Belt into the Baler and install the otherCable Lacing Pin.

Example

WHEELS & TIRES

NOTE: Our Company does NOT sell replace-ment Tires. In addition, Tire mounting, repair andreplacements should ONLY be attempted by aqualified tire manufacturer’s representative or byproperly trained personnel following the tiremanufacturer’s instructions. If you do not havesuch instructions, contact your tire dealer or ourCompany.

Check the Baler Tire pressure after every 50 hours ofoperation. Tires should be inflated to the 40 PSI (280kPa). Wheel Lug Nut torque should be checked afterevery 50 hours of operation and tightened to 90 ft-lb(124 Nm) torque.

WARNING

Inflating or servicing tires can be dangerous.Whenever possible, trained personnel shouldbe called to service and/or mount tires. Inaddition, DO NOT place your fingers on thetire bead or rim during inflation; serious injuryor amputation could result. In any event, toavoid possible death or serious injury, followthe safety precautions below:

• BE SURE the rim is clean and free of rust.

• Lubricate both the tire beads and rimflanges with a soap solution. DO NOTuse oil or grease.

• Use a clip-on tire chuck with a remotehose and gauge, which allows you tostand clear of the tire while inflating it.

• NEVER inflate beyond 35 PSI (240 kPa) toseat the beads. If the beads have notseated by the time the pressure reaches35 PSI, deflate the assembly, repositionthe tire on the rim, relubricate both partsand reinflate it. Inflation pressure be-yond 35 PSI with unseated beads maybreak the bead or rim with explosiveforce sufficient to cause death or seriousinjury.

• After seating the beads, adjust the infla-tion pressure to the recommended oper-ating pressure listed.

• DO NOT weld, braze, or otherwise at-tempt to repair and use a damaged rim.

Notes


CHAPTER 10PREPARING FOR FIELD OPERATION

PREPARING THE MATERIAL

Material to be baled should be clean and dry. Wetmaterial will cause overloading in the Baler resulting inhigh Side Sheet resistance, wrapping on the Rollers andhigh Belt tension. In addition to baling problems, wetmaterial when baled will have a tendency to spoil easieras well as be more prone to spontaneous combustion.

Hay being prepared for round baling should be wind-rowed into a 45″ or 24″ (1143 or 610 mm) windrow forthe RB1475 or, 61″ or 36″ (1549 or 914 mm) windrowfor the RB1875 Baler. Corn stalks should be severedfrom their roots. Corn stalks, straw and other brittlematerials should be raked into a full-width windrow,since these materials tend to break-up and deterioratedue to Side Sheet friction. In addition, the widerwindrow will reduce crop loss or trash build-up.

NOTE: Improper windrow widths result in bar-rel-shaped bales because of material overlap inthe center of the bale. Narrow windrow widths willrequire a weaving path across the windrow to as-sure even crop distribution as the bale is formed.

TRACTOR REQUIREMENTS &HITCH CONNECTIONS (Figs. 115 &116)

Tractor

The Round Baler MUST be operated by a tractor withthe following:

1. A minimum power output of 50 hp (37 kW)(RB1475) and 60 hp (45 kW)(RB1875) for levelground or 70 hp (52 kW)(RB1475) and 75 hp (56kW)(RB1875) for hilly terrain or high densitybales.

2. Having NON-tricycle type front wheels.

3. Having a minimum rear wheel inside dimension45″ (RB1475) or 61″ (RB1875).

4. Equipped with a PTO which runs at 540 RPM witha standard 1-3/8″ 6-tooth spline (1000 RPM op-tional conversion is available).

5. Equipped with at least one set of double acting hy-draulic outputs to operate Gate Cylinders.

6. Having standard PTO and hitch dimensions con-forming to ASAE Standard S203, as shown.

Figure 115 shows one of the two possible mountingpositions for tractors with drawbars having 13 to 17″(330 to 432 mm) high ground clearance. Figure 116shows one of the two possible mounting positions fortractors with drawbars having a ground clearancegreater than 17″ (432 mm) high.

WARNINGNEVER connect a 1000 RPM tractor to a balerequipped for a 540 RPM PTO drive.

WARNINGBecause dry material is being processed, thetractor should also be equipped with a sparkarrestor muffler, if the tractor emits sparks.

IMPORTANT: If this unit is connected to a tractorequipped with a Hammer Strap style drawbar, theHammer Strap parts shown in dashed lines MUSTbe removed to prevent damage to the unitDriveline. See Fig. 114 for details.

PTO CONNECTION (Figs. 115–119)

WARNINGDO NOT start the tractor until the locking de-vice is positively engaged to hold the tele-scoping drive couplings onto the tractor ptoshaft and baler transmission input shaft.Also, BE SURE that the drive shafts rotatefreely inside the drive shield tubes.

The Baler is equipped with a Constant VelocityTelescoping PTO Drive Shaft. This constant velocitycapability, while cornering, results in a smooth, quietrunning Drive Line, without power fluctuation.



NOTE: Whether in operation or NOT, the Maxi-mum Joint angle MUST NOT exceed 80°. Anyangle, greater than 80°, WILL result in damage tothe Joint. In addition, for continuous operation, themaximum Joint angle should be limited to 35°.Wide-angle Constant Velocity Joints are NOT de-signed for use as angled-gearboxes. Any continu-ous operation, at angles greater than 35°, will re-sult in shortening Joint life.

HYDRAULIC CONNECTIONS(Fig. 119)The Hoses for the Hydraulic Gate Cylinders areequipped with Pioneer ASAE S366.1 (SAE J1036, ISO5675) quick-disconnect couplers. The Baler is deliveredalready primed with Type F Automatic TransmissionFluid (ATF) in the Gate Cylinder control hydraulicsystem. This should be changed if this is incompatiblewith your tractor hydraulic fluid. BE CAREFUL whenhandling the Hoses and fittings to insure that they arekept free of dirt and contamination to avoid damage tothe Baler and/or tractor hydraulic system.

NOTE: The Baler comes with the Rear GateCylinder system filled with Hydraulic TransmissionFluid. MAKE SURE this fluid is compatible withyour tractor’s hydraulic system BEFORE connect-ing to the tractor. If the fluid is NOT compatible, thesystem will have to be drained and refilled with thefluid used in your tractor.

TWINE ROUTING (Figs. 120 thru124)To thread the Baler with twine, proceed as follows:

NOTE: Use the following twine routing proce-dure from each Twinebox through the Twine Tubesin the Baler Frame.1. Place up to three balls of twine in the Twinebox.

If continuous feeding is desired, route the twineend through the Guide above the twine ball on theTwinebox Cover, tie the twine ends together(always tie the outside twine end of the first ballto the inside twine end of the next ball forcontinuous feeding). On each side of the Baler,pull the end of twine from the center of the firstball and out through the hole in the side of theTwinebox.

2. Feed the twine through the Twine Tube in theFront Frame, through the Rope Guide (ManualControl models) or Twine Sensor (Auto-Electricmodels) on the Frame, through the Twine Tube onthe corner of the Hitch.

NOTE: The characteristics of the wrapping ma-terials used to wrap bales varies significantly.Therefore, the way in which the twine is routedaround the Twine Wheels (or through the RopeGuides on Manual Tie Models) is important. Toachieve optimum placement of the wrapping mate-rial on the bale. The plastic material should bewrapped around the Twine Wheels 1-1/2 times.The sisal style twine works best with a 1/2 wraparound the Twine Wheel. However, if the TwineWheel appears to be slipping, 1-1/2 wraps aroundthe Twine Wheel should be considered.

NOTE: The Twine Keeper is to be adjusted sothe Tab of the Keeper rests on the Twine Guidewhile the outside corners of the Twine Keeper areflush with the outside edges of the Twine Wheels.The Twine Keeper is to be centered between theflanges of the Twine Wheel.

1. Check for and remove any visible obstructions.

2. If windrows are very large, the Windguard can beforced into the path of the Twine Arm. Slow downground speed when full bale signal is given to re-duce the amount of crop going into the baler.

3. If E5 is displayed when the Twine Arm travelscompletely to the left side of the baler withoutpausing and then returns home:

a. The End Wrap Pause Switch is closing toolate. See manual for End Wrap Pause Switchadjustment.

b. End Wrap Pause Switch is sticking open. Tocheck for a faulty Switch, separate Harnessat Connector near the Switch. Check theSwitch continuity (using an ohmmeter orequivalent) by placing the tester leads oneach Terminal of the Leads coming from theSwitch. Whenever Magnet on the matingpart comes close to the Switch, the Switchshould close. As the Magnet moves awayfrom the Switch, the Switch should open.


d. The gap between the End Wrap PauseSwitch and magnet is too great. The air gapshould be 1/16 to 3/32″ (1.6–3.2 mm).

e. Twine Arm Stop Bolt (Fig. 66), used forstalling Actuator when applying end wrapsto left side of bale, is extended out too far.The Twine Arm Linkage is striking the StopBolt before allowing Twine Arm to pause atpause position.

f. Reset the Control System by disconnectingpower to the Implement Module. This canbe done by disconnecting the Power Chordbetween the Baler and tractor or by remov-ing and reinserting the Fuse in the BalerPower Harness.

4. If E5 is displayed when Twine Arm stalls at HomePosition:

a. The End Wrap Pause Switch is opening toolate. See manual for End Wrap Pause Switchadjustment.

b. Faulty End Wrap Pause Switch. To checkfor a faulty Switch, separate Harness at Con-nector near the Switch. Check the Switchcontinuity (using an ohmmeter or equiva-lent) by placing the tester leads on each Ter-minal of the Leads coming from the Switch.Whenever the Magnet on the mating partcomes close to the Switch, the Switchshould close. As the Magnet moves awayfrom the Switch, the Switch should open.


5. If E5 is displayed when Twine Arm stalls or hitsan obstruction while in the extending mode:

a. The Twine Arm will automatically return toHome Position.

b. Exercise the Safety Shutdown and removeobstruction.

c. Cycle tie system again.

NOTE: If Twine Arm encounters an obstructionbetween the pause position and the left side of theBaler, it will continue its normal wrapping opera-tion. However, the left portion of the bale will not bewrapped. This is usually caused by crops being fedinto the Baler too heavy while starting the twine.Slow down or stop ground speed when full bale sig-nal is given.

6. If E5 is displayed when Twine Arm stalls while inretracting position:

a. System switches to manual mode and TwineArm remains where obstruction occurred.Operator may have to manually control theTwine Arm away from the obstruction.

b. Remove obstruction.

c. Return Twine Arm to Home Position.
