COMBINE MODIFICATIONS AND SETTINGS

Bulk harvesting is no longer the primary use of this combine. Modifications to the feeding, threshing,and cleaning areas of the combine have changed the operating and performance characteristics.The following section will describe the modifications and their results on machine performance and

operation. Different settings and field adjustments are required for maximum efficiency. Section 4N"Field Adjustments and Operation" of the New Holland Operator's Manual should be read andunderstood. However, you should disregard paragraphs about the cleaning system. Settings for themodified cleaning system as well as other adjustments that change because of combinemodifications or plot harvesting will also be listed. All recommended settings are only starting pointsFurther adjustments can be made as necessary to fit specific crop, soil, and weather conditions.

HEADA New Holland four row corn head is modified for harvesting two 2-row plots. The model 974 (steeldividers) or 996 and 96C (poly dividers) heads can be used.

The head is modified to reduce plot mixing, ear loss, and carry-over. The changes also improveperformance of the head while running at the high head speeds required for small cycle timesthrough the plots. Figure C-1Head Modifications

The first change adds dividers. A center divider (wide or narrow) keeps the left and right 2-row plotsfrom mixing. The front part of the wide divider is a snout extension that helps separate the plants asthey enter the head. The second part of the wide divider attaches to the center row cover. Thesnout and center cover can still be pivoted up for gathering chain and snapping roll access. The

wide divider can be removed during bulk harvest to keep downed stalks from hanging up. Thenarrow divider is a single plate that hinges up at the head frame. Linkage arms lock the divider upfor gathering chain and snapping roll access. The rear divider is a large plate that divides the headauger and completes the transition from the center divider to the feeder house front drum. The headauger has been lowered to improve cleanout and reduce amounts of shelled corn in the head.

The second change is ear saving parts. Row divider extensions on steel heads are installed (if notalready equipped) to keep ears from rolling down the snouts. ALMACO ear savers also replaceshorter New Holland savers on steel heads. Both styles of New Holland heads have filler plates tocover open areas on the ends of the auger and expanded metal covers keep the auger paddles fromthrowing ears out of the head.

The third change removes places for ears to sit. Covers are installed on the row dividers toeliminate the flat areas that hold ears. Poly heads may have teepees to eliminate flat spots at thefront of the row divider. Head auger flighting is extended to reach the ends of the auger trough orauger drive shields are installed on the right side. Horizontal stripper plates are extended to reachthe feeder house area. Covers are mounted above the stripper plates to keep ears from sitting inthis location.

WARNING!Crushing hazard. To prevent injury or death lower head to the ground or install cylinder locksbefore working on or under the head or feeder.

Removing And Attaching The Head (1996-2000)The head modifications change the way the head is removed and attached. The following stepsmust be performed before the New Holland procedures for removal. Failure to do the addedprocedures will cause severe machine damage.

1. Remove the expanded metal covers. The covers are bolted to the head top beam and thecenter divider plate.

2. Remove the center divider plate. The plate is bolted to the feeder cradle pivot cover and thehead auger trough. The plate must be removed because it is connected to both the headand the feeder.

3. Remove the feeder stripper plate covers. The covers are bolted to the front of the feeder.These must be removed so the feeder clears the extended stripper plates.

4. Follow the removal procedures in the New Holland Corn Head Operator's Manual. See thesafety warnings and figures for more information.

Reverse the removal steps to attach the head.

Removing And Attaching The Head (2001)For heads manufactured 2001 and later, use the instructions in the New Holland Corn HeadOperators Manual.

BASE COMBINE C-5

Figure C-2 Feeder Front Modifications

The feeder (and head) speed should match the fastest ground speed through the plot. This meansthe gathering chains in the head should run slightly faster than the stalks entering the head in themiddle of the plot. If the head runs too slowly, the gathering chains push the stalks forward andincrease the chances of plugging. If the head runs too fast, stalks are jerked into the stalk rolls

possibly knocking off ears or shearing off stalks. Fixed and variable speed feeders are available, socheck the machine and operator's manual for adjustments.

FEEDERThe drives, reverser, and adjustments all remain the same as a standard feeder house. NOTE: Thecompatibility between feeder reverser and corn head varies with model and serial number. Checkthe New Holland operator's manual to see if you can use the feeder reverser with your headRemoval of the modified feeder follows the same procedures as a standard feeder. Please seesection 4A "MAINTENANCE Feeder" in the New Holland Operator's Manual for more information.

The Terrain-Tracer tilt cylinders (if so equipped) have been replaced with manual turnbuckles. Theturnbuckles level the head with the feeder house and keep the divider plate transition from twistingStripper plates on the front of the feeder are longer to improve material flow.

The feeder house is split down the middle with a steel plate to keep the plots separate as they movefrom the head to the threshing area. Filler ramps between the head auger and front drum keep earsfrom hanging up. The fillers also contact the sounding board for the electronic stone trap (if soequipped).

Figure C-3 Feeder Inside Modifications

The front drum and stone roll are modified to seal around the divider plate. Two sets of drag chainsare utilized and care must be used when adjusting chain tension. Both sides should be adjustedequally to keep the chains the same length. Due to inconsistencies in the lower drum and sprocketpitch diameters, ALMACO has added adjusters to compensate for unequal length chains. Theseadjusters should be used to adjust the individual chains so the drag chain bars are parallel with thefloor of the feed housing.

INTERIORThreshingThe splitting of the combine interior starts with a transition plate between the feeder house and therotor inlet. This plate keeps the material separate regardless of head position. The only modificationto the rotor/concave area is the addition of steel and rubber seals down to the grain pan.

Figure C-4 Rotor Area Modifications

The threshing area was originally designed to run full continuously. In plot harvesting, the threshingarea gets plots of crop material intermittently. Some incomplete threshing may occur at the

beginning and end of the plot. This is due to the threshing area filling up and emptying out. Therotor speed and concave setting should be set for the middle of the plot when the threshing area isfull. As described in the New Holland operator's manual, a slower rotor speed and wider concaveclearance work together for corn. An average setting is required to match changing crop conditionsfrom plot to plot. ALMACO recommends an initial rotor speed of 650 rpm and a concave setting of12. See your New Holland dealer for options to increase or decrease concave aggressiveness.

SeparatingThe grain pan dividers are centered and rake assemblies are removed. The rakes are replaced withramps to get the threshed material further into the cleaning fan air stream. Curtains are added todeflect the initial spray of grain from the separation grates onto the sieve. TR89 models use stock

rake assemblies and no curtains. Beater grate covers are installed to reduce the chance of plotmixing in the discharge beater area. See the New Holland operator's manual for beater grate anddeflector settings.

Most of the separating occurs in the threshing area. If a large amount of crop material is in theseparation areas (grain pan and discharge beater), there is a possibility that the material is under-threshed.

CleaningThe cleaning area is modified in the following ways. The chaffer (upper) and sieve (lower) areremoved and dual adjusters are added (if not already equipped). Only the chaffer (upper) position isused. The sieve has smaller openings and is typically used in the chaffer position. However, cropand harvest conditions vary and the larger openings of the chaffer may be needed. Rubber flashing

is added below the center of the sieve direct material away from the lower shoe divider.

Figure C-5 Sieve Modifications

Splitting modifications have changed the cleaning area from 2-stage to 1-stage cleaning with noreturns. Only 1 sieve (or chaffer) and chaffer extension is used in the upper position to remove chaffand trash from the grain sample. Only using one sieve changes the performance characteristics andadjustments of the cleaning system. ALMACO recommends initially using the cleaning (lower) sieveand not the chaffer (upper) sieve.

The cleaning fan regulates the amount of air passing through the sieve. If fan rpm is too high, grain

will blow out over the sieve. If fan is too low, losses will occur due to trash matting on the sieve.ALMACO recommends an initial fan speed of 650-750 rpm. Note: Only adjust fan rpm whileseparator is running.Dual adjusting levers on the sieve (and chaffer) allow the front third of the sieve to be adjustedseparately. Typically, the front section would be opened wider than the rest of the sieve. Thisallows more air through the sieve where the grain pan dumps. If the sieve opening is too small,grain will be lost out the back. If the sieve opening is too large, grain samples will have excessiveamounts of trash. The front section should have a 1/2" opening and main section should have a 3/8"opening. Increasing the sieve angle will also cause more material to pass through the sieve. Therear of the sieve should start in the middle position.

The chaffer extension also has louver and angle adjustments. The louver opening should be thesame to slightly wider than the sieve opening (3/8" to 1/2'). The extension angle regulates flow ofmaterial off of the sieve. An angle of the extension slightly higher than the sieve angle isrecommended. Too much angle will retard flow and could plug the sieve.

Clean GrainNext, the lower shoe is modified so that the clean grain is delivered to the Sample HandlingSystems. A center divider panel is installed to keep the sides separate and to mount ramps tofunnel grain to the front or rear auger or air tube locations. Seals block crossover from cleaning fanair and flash the moving shoe from the stationary auger bed or metering wheel sump.

HYDRAULIC (REEL) DRIVE (see New Holland Manual)The Sample Handling Systems use the reel drive pump to power different styles of return andfountain augers. The auger speeds are set by chain drive sprocket ratios or hydraulic motordisplacement (on direct coupled applications) but can be adjusted with the reel speed control. Note:The reel speed knob must be turned clockwise (fast) for the Sample Handling System to keep up

during bulk harvesting. Combines equipped with Automatic Reel Speed Control must have theselector switch in the "manual" position.

WARNING!High-pressure fluids can cause serious injury. Release pressure before disconnecting orservicing hydraulic lines or components.

WIRINGThe electrical modifications provide isolated power to the Sample Handling and Data CollectionSystems. A 20-amp circuit breaker is added to the breaker panel in the engine compartment. Oneground and two +12V wires are routed to the cab. One +12V line powers the Seed Spector directly

and the other line powers the control boxes after an ignition relay.

The ignition relay and fuse block are located behind the combine monitor in the cab. Printers,handheld computers, video camera systems, lights, clutches, etc. are powered from the fuse blockand labeled with fuse size and location. Optional power ports can be added for handheldcomputers, cell phones, and other 12V accessories.

WARNING!Shock hazards can cause serious injury or death. Only qualified personnel should service electricasystems.

C-12 BASE COMBINE

FIELD OPERATION CHECKLISTSSeveral events must take place before you are ready to harvest. The "Field Operation Checklist"helps make sure everything is ready to go for the correct mode of operation. This list is intended asa start-up check. It is assumed that all necessary calibrations, adjustments, and maintenance

procedures have been performed and the combine is ready for operation.

Bulk Harvest Mode

1. Check the weigh hopper position. The weigh hoppers should be locked in the transport positionif bulk material will be harvested.

2. Start the engine. Sample handling electrical system comes on with the ignition switch. Indicatorlights should be on and doors in the closed position. The data collection system need not be onfor bulk harvesting.

3. Lock open the doors or Divert the Y valves. Switch holding hopper, test weigh hopper, andweigh hopper doors to the 'LOCKOPEN' position. If machine has y valves, switch the valves tothe 'LOCKOPEN' position to divert grain to the grain tank.

4. Engage the thresher clutch. The thresher clutch will start the mechanical drives of the samplehandling system. This includes cross augers, elevators, and holding hopper augers.

5. Engage the head and feeder clutch. The head and feeder clutch will engage the reel drivepump. The reel drive runs the hydraulic motors on the sump return augers and the fountainauger.

6. Adjust reel speed control. Make sure the reel speed control knob is turned clockwise forsufficient auger speed. Failure to do this could cause bottlenecks in the sample handlingsystem. Grain spillage and system damage could result.

7. Adjust engine rpm and begin harvesting. The combine must operate at full engine rpm for shaftspeeds to be correct. For more information on combine operation and field adjustments, see"Maintenance Field Adjustments and Operation" in the New Holland operators manual.

Plot Harvest Mode

1. Check the weigh hopper position. The weigh hoppers must be in the operating position. If not,the sample weights will not be measured correctly.

2. Start the engine. Sample handling electrical system comes on with the ignition switch. Indicatorlights should be on and doors in the closed position.

3. Turn on the data collection system. The Seed Spector, hand-held computer, printer, and anyother electronic equipment should be turned on and ready to go. See the "Data CollectionSystem" section of this manual for more information.

4. Engage the thresher clutch. The thresher clutch will start the mechanical drives of the samplehandling system. This includes cross augers, elevators, and holding hopper augers.

5. Engage the head and feeder clutch. The head and feeder clutch will engage the reel drivepump. The reel drive runs the hydraulic motors on the sump return augers and the fountainauger.

6. Adjust reel speed control. Make sure the reel speed control knob is turned fully clockwise formaximum auger speed. Failure to do this could cause bottlenecks in the sample handlingsystem. Grain spillage and system damage could result.

7. Adjust engine rpm and begin harvesting. The combine must operate at full engine rpm for shaftspeeds to be correct. For more information on combine operation and field adjustments, see"Maintenance Field Adjustments and Operation" in the New Holland operator's manual.

ALMACO has designed and manufactured several types of sample handling systems. The followingsection covers the ALMACO systems only. If you have a different brand of system, please refer tothat system manual or manufacturer for information.

REAR BUCKETS ELEVATOR SYSTEM

This sample handling system mechanically moves grain from the cleaning area to the data collectionareas just in front of the rear wheel on each side to the grain tank. The grain moves from crossaugers below the cleaning shoe to elevators. The elevators lift the grain above the holding hoppers.Small augers move the grain from the elevators into the holding hoppers. Once the grain reachesthe holding hoppers, the plots are dumped into the weigh hoppers. The weigh hoppers dump thesample into return auger sumps. The right side sample moves into the clean grain elevator, throughthe bubble-up auger, and to the grain tank. The left side sample moves into the fountain auger thento the grain tank.

Figure D-1Rear Buckets System

The rear buckets system also has a bulk harvest mode. All doors and hoppers are locked openallowing grain to flow through the system directly into the tank. The system has been oversized toallow for the higher volume of grain. Normal harvest speed for a 4-row head is possible.

The following covers function and adjustment of various aspects of the rear buckets system.Figures may show guards removed for clarity. Read and follow all safety information whenoperating or performing any maintenance.

Cross AugersThe cross augers move the clean grain from the cleaning shoe and center fills the elevators. Seven-inch auger flighting is used to reduce tolerances and clean out the shoe area between plots. Theauger bottom covers are installed to reduce kernel damage. The left and right side chain drives (seebelow) turn the augers. The augers in turn drive the lower shaft of the elevators. The cross augers

should turn at 385 to 390 rpm.

Right Side DriveThe right side chain drive is located on the clean grain elevator lower shaft. The shaft rotation isreversed and then turns the front cross auger, the left elevator, and the left holding hopper auger.This drive utilizes the clean grain elevator ratcheting slip clutch in case of a plugged elevator orauger. The combine monitor shows an error on the clean grain elevator if a problem occurs with thisdrive.

Holding HoppersThe holding hoppers get grain from the holding hopper augers. The augers are mounted in theelevator head assemblies. The augers are driven from the elevator top shafts. The auger turnsabout 600 rpm. The drive chains are adjusted by moving chain idlers in mounting slots. SeeElevators in this section for holding hopper auger drive components.

The holding hoppers store the grain until the weigh hoppers are finished taking measurements. Awiper motor activates the holding hopper door. The door timing can be adjusted by rotating thewiper motor cam arm. Caution: turning the motor manually can cause internal damage. Make surethe motor is in the parked position, and then loosen the nut holding the cam arm on the wipermotor. Rotate the arm until the door is in the closed position. Tighten the nut holding the arm tothe motor shaft. Cycle the holding hopper door and adjust the arm as necessary to get the dooropen position to match the maximum stroke. A leaf-type microswitch stops the wiper motor whenthe door is in the open position. The arm on the motor touches the leaf and activates the switch.The switch location is fixed relative to the motor. Bending the leaf will change where the motorstops.

Grain SensorsThe holding hoppers can be modified to include grain sensors. The sensor is useful for detectingimproper functioning of the holding hopper door during plot harvesting, or a closed hopper doorduring bulk harvest. When grain reaches approximately half way up in the holding hopper it willcome in contact with the sensor. The sensor sounds an alarm in the cab and an indicator lightilluminates. The alarm can be disabled by turning the switch on the left side of the Sample HandlingCab Control Box to off. This disables the audible alarm, but the indicator light will still be illuminated.Once the problem is fixed turn the alarm switch back to the on position.

Weigh Hopper MountsThe weigh hoppers have both an operating and a transport mode. In the operating mode, two pinsconnect the hopper mount assembly (including load beam) to the hopper frame. In the transportmode, the top pin is removed and stored in a holder on the frame. The hopper rotates down untiltabs sit on the frame. Toggle clamps lock the tabs flat on the frame. This protects the load beams

from the shock and vibration associated with on-road travel, trailering and bulk harvesting. The tabsare adjustable to keep the toggle clamps from adding additional loads to the load beams. The tabsare set at the factory and should not need adjustment unless the weigh hoppers are removed.

Return AugersThe return augers are located in the sumps under the weigh hoppers. The augers transfer the grainfrom the weigh hoppers to either the New Holland clean grain elevator or the ALMACO fountainauger. Cleanout doors are built into the bottom of the auger tubes. Hydraulic motors turn theaugers through a chain drive. Adjust the chain drive by loosening the mounting bolts for the moto

and sliding the motor in the slots.

CAB BUCKETS AIR DELIVERY SYSTEM

This sample handling system pneumatically moves grain from the cleaning area to the datacollection area on the right side of the cab. The cyclone blower generates the airflow that moves thegrain. The metering wheel assembly feeds grain from the cleaning system into the air delivery

tubes. The grain then moves through the diverting valves. The valves can divert grain to theoptional bulk harvest cyclone (bulk harvest) or to the holding hoppers (sample harvest). Once thegrain reaches the holding hoppers, the plots are dumped into the weigh hoppers while the divertingvalves vent the blower air. The weigh hoppers dump the sample into the return auger. The augermoves the samples into the New Holland bubble-up auger, which takes the grain to the grain tank.

Figure D-10Air Delivery System

The sample handling system (without a bulk harvest cyclone) also has a bulk harvest mode. Aldoors and hoppers are locked open allowing grain to flow through the system directly into the tankThe system has been oversized to allow for the high volume of grain. Normal harvest speed for a 4-row head is possible.

The following covers function and adjustment of various aspects of the air delivery system.Read and follow all safety information when performing any maintenance.


47/101



Cyclone BlowerThe cyclone blower generates the air streams for the air delivery system. The split impellerdevelops two separate air streams out of the split housing. The housing has an access door in thefront to reach the impeller fins for cleaning. The cyclone blower is driven by a v-belt from anadditional engine pulley. A gas shock loaded idler arm provides the correct belt tension. The

cyclone blower clutch is engaged with the New Holland threshing clutch switch.

Sump and Metering WheelsThe sump forms the transition between the cleaning system and the air delivery system. The sumpholds seals for the lower shaker shoe, air delivery tubes, metering wheels, and drive shafts. Themetering wheels control the amount of grain dropped into the air stream. The metering wheels arehex shafts with replaceable rubber paddles that move grain into the air tubes while keeping the air

out of the cleaning system. Removable end caps allow quick removal of the wheel assemblies.

Diverting ValvesThe diverting valves main function is to vent cyclone blower air from the holding hoppers so samplesdrop into the weigh hoppers quickly. The valves open at the same time as the holding hoppers. Thevalves can be closed two ways. If they close at the same time as the hopper, cyclone air may puffthe sample in the test weight chamber. The holding hopper closed switch can also be used to close

the diverting valves after the holding hopper door closes.

Linear actuators (or optional air cylinders) shift the valves. The valve door sets in pockets in thevalve body when fully shifted. This reduces crossover and allows for variation in the shiftingmechanism. Switches in the cab lock the valves closed for bulk harvest mode. The valves can beconnected to an optional bulk harvest cyclone so that grain goes directly to tank in bulk harvest

mode instead of through the weigh system and back to tank. See OPTIONS section for moreinformation.

Holding HoppersHolding Hoppers (also called cyclones on air delivery systems) hold the samples from the plotscurrently being harvested while the previously harvested plots are being measured in the weighhoppers (or other intrinsic property measuring device). The holding hoppers have removablescreened tops that vent cyclone blower air and allow access inside the hoppers. Quarter-turn

fasteners secure the lids. The holding hoppers have lights for night operation and viewing windowsfor visually confirming sample size and location.

Linear actuators (or air cylinders) open and close the holding hopper doors. If your holding hoppershave wiper motors, see REAR BUCKETELEVATOR SYSTEM Holding Hoppersfor operationand adjustment. To adjust the door, retract the actuator (door open). Move the actuator mount untilthe door opens far enough to eliminate any ledge. This gives the most spring pressure on the doorwhen closed. Moving the mount out further will reduce spring pressure and open the door more.

Once the actuator is set, adjust the microswitches. The microswitches sense open and closedpositions of the door. Adjust the switches by loosening the mounting screws and moving the switchbody relative to the door. The holding hoppers may also have optional grain level sensors. SeeREAR BUCKETELEVATOR SYSTEM Holding Hoppers Grain Sensor for more information.

Environmental EnclosureThe environmental enclosure protects the weigh hopper area and holds several components thatmake operation and maintenance user-friendly. A cab-style door opens up the entire weigh hopperarea. Lights and clear viewing panels make weigh hopper operations visible. Side station controlsare conveniently located for both operating and servicing weigh hoppers. Additional features are

listed below.Enclosure Door and LidThe enclosure door uses a cab-style latch and gas shocks to hold the door open for maintenanceand service. The right side mirror is relocated on the enclosure door. The lid keeps dirt andmoisture out of the holding hoppers during transport. The lid must be open during operation of theair delivery system. Unlatching the camlock opens the lid and gas shocks hold it in the operatingposition. Caution: Failure to latch the lid for transport could cause damage.

HIGH CAPACITY GRAIN GAGE ELEVATORS SYSTEM

This sample handling system mechanically moves grain from the cleaning area to the data collectionarea on the right side of the cab. The New Holland tailings cross auger (rear) now moves grain to

an extended tailings elevator on the outside of the machine. This elevator lifts grain to the right(outside) holding hopper on the High Capacity Grain Gage (HCGG). The New Holland clean grainelevator is removed. The New Holland clean grain cross auger (front) now moves grain to anextended tailings elevator inside the tailings elevator. This elevator lifts grain to the left (inside)holding hopper on the HCGG. Isolator valves on the elevator heads keep any trickling grain in theelevators while the HCGG is measuring. After the grain is measured, the grain is dumped into thereturn auger and carried to the New Holland bubble-up auger and to the grain tank.

Figure D-21HCGG Systems

The sample handling system also has a bulk harvest mode. All valves and hoppers are locked openallowing grain to flow through the HCGG directly into the tank. The system has been oversized to

allow for the high volume of grain. Normal harvest speed for a 4-row head is possible.

The following covers function and adjustment of various aspects of the sample handlingsystem. Read and follow all safety information when performing any maintenance.

Cross Augers (TR86-88)The cross augers move the clean grain from the cleaning shoe and center fills the elevators. Seven-inch auger flighting is used to reduce tolerances and clean out the shoe area between plots. Thesolid auger bottom covers are installed to reduce kernel damage. The returns elevator chain drive(see below) turns the augers. The augers in turn drive the lower shaft of the elevators. The cross

augers should turn at 385 to 390 rpm.

The drives use the returns elevator (tailings) drive to turn the rear cross auger and right elevator.The NH ratcheting clutch has been replaced with a torque limiter that slips in case of a pluggedelevator or auger. A second chain drive from the returns elevator drive turns the front cross augerand left elevator. The returns elevator sensor was moved up to the right elevator head and theclean grain elevator sensor is located at the left elevator head. This way, the combine monitorshows an error on the returns or clean grain elevators if a problem occurs with these auger andelevator drives.

Cross Augers (TR89)The cross augers on the TR89 also move the clean grain from the cleaning shoe and center fills theelevators. The stock augers are used but lowered to reduce tolerances and clean out the shoe areabetween plots. The solid auger bottom covers are installed to reduce kernel damage. The stock NHreturns elevator chain drive (see below) turn the augers. The augers in turn drive the lower shaft o

the elevators. The cross augers should turn at 385 to 390 rpm and use NH bearings.

The drives use the returns elevator (tailings) drive to turn the rear cross auger and right elevator.The stock NH ratcheting clutch drives the rear auger while a second ratcheting clutch was added todrive the front auger. The returns elevator sensor was moved up to the right elevator head and theclean grain elevator sensor is located at the left elevator head. This way, the combine monitorshows an error on the returns or clean grain elevators if a problem occurs with these auger andelevator drives.

ElevatorsThe elevators lift grain from the cross augers through the isolator valves and to the holding hoppersof the High Capacity Grain Gage. The solid bottom elevator covers are installed to reduce seeddamage in the pick up area. Both elevators are extended using NH tailings elevator sections andtailings elevator chains. The stock chains have 2 or 3 bolt-on elevator paddles. These paddles are

replaced with UHMW plastic paddles for faster cleanout. See the New Holland Operators Manual Grain Handling Systemfor chain adjustments and maintenance information.

Isolator ValvesThe isolator valves are mounted to the discharge end of the elevators. The valves close while theHCGG cycles both holding hoppers. This makes the seed trickle uniform from side to side. Thevalves are controlled by the HCGG and operated by air cylinders. Assist springs hold the valvedoors shut when the electronics system is off and the compressed air system is locked out or at zero

pressure. This allows the HCGG to be rolled into its calibration (service) position.

HCGG MountThe High Capacity Grain Gage mounting system has 2 positions to make HCGG operation andcalibration easy. The operating position has an adjustable rubber stop pad and spring loadedlatches to hold the HCGG securely in place. The spring-loaded latches can be locked out and theHCGG rolls out to the calibration position on stainless steel precision drawer slides. Note: The

isolator valves and weigh hopper door must be closed when changing positions of the HCGG.Drawer slides may need to be blown out with compressed air occasionally to keep rollers and tracksfree from seed and debris.

PLATFORM AND LADDER (TR89 only)Because of the TR89s larger size, an optional platform may be installed to provide access to theHCGG in the operating position and increase serviceability. The platform ladder has a latch thatholds it up in the transport position. Lifting the latch while starting to lower the ladder will let the gasshock move it to the access position. Lift the ladder fully and the latch will automatically lock the

ladder for transport.

RETURN AUGERThe return auger is located in the sump under the HCGG mount. The auger transfers the grain tothe New Holland bubble-up auger. A cleanout door is built into the bottom of the auger tube. Ahydraulic motor is directly coupled to the auger. Adjust flighting clearance by loosening themounting bolts for the motor and sliding the motor in the slots. Poly flighting eliminates the need for

a bearing on the discharge end.

The reel drive pump drives the hydraulic motor. Note: the head must be engaged and the reel driveswitch must be in the manual mode for the auger to run. The rotary switch in the dash controls theauger speed. The auger speed should be just fast enough to move the grain without piling up in plotor bulk harvest modes. Excessive auger speed will cause premature wear.

DATA COLLECTION SYSTEMS E-3

There are several brands commercial and custom data collection systems. If you are using asystem not supplied by ALMACO, please refer to your system documentation for operation andcontrol information. For ALMACO supplied bucket systems, see below.

ALMACO WEIGH HOPPER SYSTEM

The manual operation of the Data Collection System uses the controls described in the followingsection. The automatic operation is controlled by various hardware and harvest software systems.See the applicable hardware (eg. Seed Spector) and software (eg. ALMACO Harvest Software)manuals for more information.

Cab ControlsThe cab remote control box allows complete system operation from the driver's seat. The systemcomes on with the ignition switch and immediately indicates striker and door positions. All doorsshould be closed in the "rest" position. Red LED's show fully closed and fully open positions forfunctions on both sides of the system. Functions on the control box are listed from top to bottom in

the same order the samples move through the system. The control box is connected to the SeedSpector. This allows some type of harvest software to control the data collection system.

The holding hoppers, test weight hoppers, and weigh hoppers have 3 position (on - off - momentaryon) toggle switches to operate the doors. The middle (off) switch position is 'AUTO'. The 'AUTO' (orrest) position is used when harvest software operates the sample handling system. The top(momentary on) position is 'MANUAL OPEN'. The door opens when the switch is pushed andreturns to "rest" when released. Manual door opening is used for clean out, manual cycling, and

diagnostic checks. The bottom (on) switch position is 'LOCK OPEN' and the door remains open untilswitched back to 'AUTO'. This position holds the door open for bulk harvesting. Note: All hopperdoors must be locked open in bulk harvesting mode (unless equipped with bulk harvest cyclone).

The strikers have a 2 position (off - momentary on) toggle switch. The bottom (off) switch position is'AUTO'. The 'AUTO' (or rest) position is used when harvest software operates the striker. Note: Thestriker switch is left in the 'AUTO' position for bulk harvest. The top (momentary on) position is'MANUAL'. The striker swipes the test weight chamber when the switch is pushed and returns to"rest" when released. The cab control box also has panel fuses for each side control box. Thefuses are located in the left face of the box and provide power for manual and automatic operation.
