Important Safety Information

Look for Safety SymbolThe SAFETY ALERT SYMBOL indicates there is apotential hazard to personal safety involved and extrasafety precaution must be taken. When you see thissymbol, be alert and carefully read the message thatfollows it. In addition to design and configuration ofequipment, hazard control and accident prevention aredependent upon the awareness, concern, prudence andproper training of personnel involved in the operation,transport, maintenance and storage of equipment.

Be Aware of Signal WordsSignal words designate a degree or level of hazardseriousness.

DANGER, and the color Safety Red, indicate animminent hazard which, if not avoided, will result in deathor serious injury. This signal word is limited to the mostextreme situations, typically for machine componentsthat, for functional purposes, cannot be guarded.

WARNING, and the color Safety Orange, indicate apotential hazard which, if not avoided, could result indeath or serious injury, and includes hazards that areexposed when guards are removed. It may also be usedto alert against unsafe practices.

CAUTION, and the color Safety Yellow, indicate apotential hazard which, if not avoided, may result inminor or moderate injury. It may also be used to alertagainst unsafe practices.

Prepare for Emergencies Be prepared if a fire starts

Keep a first aid kit and fire extinguisher handy.

Keep emergency numbers for doctor, ambulance, hospitaland fire department near phone.

Be Familiar with Safety Decals Read and understand “Safety Decals” on page 6,

thoroughly.

Read all instructions noted on the decals.

Keep decals clean. Replace damaged, faded and illegibledecals.



Wear Protective Equipment Wear protective clothing and equipment.

Wear clothing and equipment appropriate for the job.Avoid loose-fitting clothing.

Because prolonged exposure to loud noise can causehearing impairment or hearing loss, wear suitablehearing protection such as earmuffs or earplugs.

Because operating equipment safely requires your fullattention, avoid wearing entertainment headphones whileoperating machinery.

Handle Chemicals ProperlyAgricultural chemicals can be dangerous. Improper usecan seriously injure persons, animals, plants, soil andproperty.

Do not use liquid seed treatments with the 3P606NT or606NT.

Read and follow chemical manufacturer’s instructions.

Wear protective clothing.

Handle all chemicals with care.

Avoid inhaling smoke from any type of chemical fire.

Never drain, rinse or wash dispensers within 100 feet(30 m) of a freshwater source, nor at a car wash.

Store or dispose of unused chemicals as specified bychemical manufacturer.

Dispose of empty chemical containers properly. Lawsgenerally require power rinsing or rinsing three times,followed by perforation of the container to prevent re-use.

Avoid High Pressure Fluids(Model 605NT or 606NT only)

Escaping fluid under pressure can penetrate the skin,causing serious injury.

Avoid the hazard by relieving pressure beforedisconnecting hydraulic lines.

Use a piece of paper or cardboard, NOT BODY PARTS, tocheck for suspected leaks.

Wear protective gloves and safety glasses or goggles whenworking with hydraulic systems.

If an accident occurs, seek immediate medical attentionfrom a physician familiar with this type of injury.



Use an Adequate TractorModel 3P605NT or 3P606NT only:

Ensure that the tractor is rated for, and correctly ballastedfor the drill’s 3-point loading. Check that drill plus ballastdoes not exceed the tractor’s capability.

Avoid transport with material loaded in boxes.

Model 605NT or 606NT only:

Ensure that the tractor weighs at least 2/3 (67%) of thedrill (including the weight of any Options and materials).


Use A Safety Chain(Model 605NT or 606NT only)

Use a safety chain to help control drawn machineryshould it separate from tractor drawbar.

Use a chain with a strength rating equal to or greater thanthe gross weight of towed machinery.

Attach chain to tractor drawbar support or other specifiedanchor location. Allow only enough slack in chain topermit turning.

Replace chain if any links or end fittings are broken,stretched or damaged.

Do not use safety chain for towing.

Keep Riders Off MachineryRiders obstruct the operator’s view. Riders could bestruck by foreign objects or thrown from the machine.

Never allow children to operate equipment.

Keep all bystanders away from machine during operation.

Use Safety Lights and DevicesSlow-moving tractors and towed implements can createa hazard when driven on public roads. They are difficultto see, especially at night.

Use flashing warning lights and turn signals wheneverdriving on public roads.

Use lights and devices provided with implement



Transport Machinery SafelyMaximum transport speed for the implement on its owntires is 20 mph (30 kph). Rough terrain may require aslower speed. Sudden braking can cause a towed loadto swerve and upset.

Do not exceed 20 mph (30 kph). Travel only at a speedwhich allows adequate control of steering and stopping.

Comply with state and local laws.

Carry reflectors or flags to mark drill in case ofbreakdown on the road.

3-point implements reduce weight on steering tires. Verifythat tractor is correctly ballasted. Watch for signs of poorsteering traction.

Shutdown and Storage Park on level ground.

Unhitch and store the drill in an area where childrennormally do not play.

Tire SafetyTire changing can be dangerous and should beperformed by trained personnel using correct tools andequipment.

When inflating tires, use a clip-on chuck and extensionhose long enough for you to stand to one side–not in frontof or over tire assembly. Use a safety cage if available.

When removing and installing wheels, use wheel-handlingequipment adequate for weight involved.

Practice Safe Maintenance Understand procedure before doing work. Use proper

tools and equipment. Refer to this manual.

Work in a clean, dry area.

Lower the drill, put tractor in park, turn off engine, andremove key before performing maintenance. If workmust be performed with implement raised, use blocks orjackstands rated for the drill weight.

Make sure all moving parts have stopped and all systempressure is relieved.

Allow drill to cool completely.

Disconnect battery ground cable (-) before servicing oradjusting electrical systems.

Welding: Disconnect battery ground. Avoid fumes fromheated paint.

Inspect all parts. Make sure parts are in good conditionand installed properly.

Remove buildup of grease, oil or debris.

Remove all tools and unused parts from drill beforeoperation.



Safety At All TimesThoroughly read and understand the instructions in thismanual before operation. Read all instructions noted onthe safety decals.

Be familiar with all drill functions.

Operate machinery from the driver’s seat only.

Height and Leveling the DrillHeight Setup: Model 3P605NT or 3P606NTRefer to Figure 9 and Figure 10

1. Initially adjust drill so opener tool bar runs 243/4 in. (62.9 cm) above ground when drill is lowered inthe field.

2. The drive wheel should be in the fourth mountinghole from the top (factory setting).

The drive may need to be adjusted due to groundconditions.

3. Level drill with top 3-point link.

Adjusting 3-Point Height

Raising the gauge wheel spindle provides deeper coulterdepth. Lowering the wheel provides shallower depth.

Do not lower coulters to aid in penetrating hard soil.Instead, increase coulter down-force (page 33). Thismay require adding optional weight (page 31).

Refer to Figure 10

1. Determine new coulter depth desired. With newdiscs, the axle holes provide these depths:

2. Raise drill, unless wheel is already off groundsufficiently to allow wheel spindle relocation.

3. Relax chain idlers.

4. Remove wheel bolts. Move spindle to new hole pair.Re-install wheel bolts.

5. Re-engage chain idlers.

Height Setup: Model 605NT or 606NTSet Tool Bar Height

Refer to Figure 11 and Figure 12

Tool bar height is controlled by a depth stopassembly on the left lift cylinder.

The suggested initial tool bar operating height is:243/4 in. (62.9 cm)

from the base of the opener tool bar to the ground, whenlowered in field conditions (opener discs in ground).

1. Use the tractor remote circuit to raise the drill to thefull extension of both lift cylinders. Hold the drillraised for several seconds to re-phase the cylinders.Remove any transport locks.

2. In field conditions, lower the drill to the desired toolbar height. Pull forward to put openers in ground.Set the remote to Neutral. Shut off the tractor.

3. Loosen the nut and bolt that secure the stopweldment to the cylinder rod.

4. Slide the weldment up the rod until it contacts thevalve actuator , then slide it up another 1/8 in. (3 mm). Tighten the bolt.

5. Start the tractor. Raise and lower the drill. Pullforward in ground. The lowering stops when theweldment moves the actuator a short distance.Shut off the tractor and verify the tool bar height.

If further adjustment is required, the drill heightchanges at approximately half the change inweldment position. For example, raising the drillanother 1/8 in. (3 mm) would require moving theweldment up another 1/4 in. (6 mm).

Level Model 605NT or 606NT

Operation Instructions

This section covers general operating procedures.Experience, machine familiarity and the followinginformation will lead to efficient operation and goodworking habits. Always operate farm machinery withsafety in mind.

Pre-Start Checklist

High Pressure Fluid Hazard:Escaping fluid under pressure can have sufficient pressure topenetrate the skin. Check all hydraulic lines and fittings beforeapplying pressure. Fluid escaping from a very small hole canbe almost invisible. Use paper or cardboard, not body parts,and wear heavy gloves to check for suspected leaks. If anaccident occurs, seek immediate medical assistance from aphysician familiar with this type of injury.

1. Carefully read “Important Safety Information”starting on page 1.

2. Lubricate drill per “Lubrication and ScheduledMaintenance” starting on page 48.

3. Check all tires for proper inflation. See “TirePressures” on page 60.

4. Check all bolts, pins and fasteners. See “TorqueValues Chart” on page 61.

5. Check drill for worn or damaged parts. Repair orreplace faulty parts before going to the field.

6. Check hydraulic hoses, fittings and cylinders forleaks. Repair or replace faulty parts before going tothe field.

7. Rotate both drive wheel to verify that the drive andmeters are working properly and free from foreignmaterial.

Falling Hazard:Watch your step when walking on drill steps and walkboard.Falling from drill could cause severe injury or death.

WARNINGTo avoid serious injury or death:

Watch your step when climbing ladder orwalking on walkboard.

838-102C



Transporting 3P605NT or 3P606NTTransport considerations are different for 3-point andpull-type models. For pull-type, see page 21.

Use an Adequate Tractor (3-Point)

Loss of Control Hazard:Insufficient weight on tractor steering tires can dangerouslyreduce steering authority, particularly during acceleration andascending hills. You can lose directional control entirely,which could result in a major accident, serious injury, ordeath. Adding too much ballast could lead to brake or othermechanical failures, tire failures and loss of control.

Ensure that the tractor is rated for, and correctly ballastedfor the drill’s 3-point loading. Check that drill plus ballastdoes not exceed the tractor’s capability.

If the drill has accessory weight brackets, considermoving any tractor weights present to the tractor duringtransport.


The total drill weight and center of gravity varyconsiderably with drill configuration and material load.See table below.

Transporting 605NT or 606NTTransport considerations are different for 3-point andpull-type models. For 3-point, see page 20.

Use an Adequate Tractor (Pull-Type)

Loss of Control Hazard:Insufficient tractor weight can dangerously reduce steeringauthority, and increase braking loads beyond the capability ofthe tractor. You can lose directional control entirely, whichcould result in a major accident, serious injury, or death.

Ensure that the tractor weighs at least 2/3 (67%) of thedrill (including the weight of any Options and materials).


The total drill weight varies considerably with drillconfiguration and material load. See table below.



605NT or 606NT Example Weights

Use Transport Locks

Transport Hazard:Failure of hydraulic cylinders during transport causes drill todrop suddenly, which could lead to a serious accident, injuryor death. To prevent an accident, always install cylinder locksbefore transporting drill.

Before transporting the drill, check these items:

Cylinder Locks

Refer to Figure 14 or Figure 15, and Figure 16

A cylinder lock is provided for both gauge wheelhydraulic lift cylinders.

Transport CautiouslyKeep Clearance in Mind

Remember that the drill may be wider than the tractor.Allow safe clearance.

Observe Road Rules

Comply with all national, regional and local safety lawswhen traveling on public roads.

Reduce speed on rough roads.

Loading Seed

Possible Chemical Hazard:Take all prescribed material safety precautions.

Fully loaded with dense seed, the drill weighs anadditional 1155 lbs (529 kg). Include this weight whenchecking tractor capability.

The drill must be hitched for seed loading.

Load slightly more material than needed, becauseconsumption rates can vary between compartmentseven though the furrow rates are identical.

Main Seed Box Loading1. Check that all meter doors are positioned for the

seed size, and not set for clean-out. See “PositionSeed Cup Doors” in seed Rate Manual. If loadingprior to transport, set them to position 1 (smallestseed).

2. Install or remove optional seed plugs as desired forthe row spacing planned. Refer to Seed RateManual.

If loading prior to transport, and calibration has not yetbeen done, set Seed Rate Handle to 0. At 0, and with thedoors at 1, no seed can leak during transport.

3. The main seed box lid handle is also a latch. It needsto pivot up to release the lid.

4. Load seed evenly into compartments.

To reduce wear on unused boxes that may also bepresent:

• Remove final drive chain for Small Seed box.

• Remove any Native Grass chain.

Loading Native Grass Box1. The main seed box lid handle is also a latch. It needs

to pivot up to release the lid.


3. Add 1/3 cup (80 mL) graphite seed lubricant on top ofthe loaded seed. In humid conditions, double or triplethis amount as needed.

Loading Small Seeds Box1. If loading prior to transport, and calibration has not

yet been done, set Seed Rate Handle to 0. At 0, noseed can leak during transport.

2. Take all necessary materials safety precautions if theseed is treated.

3. The Small Seeds lid is held closed by two externalrubber latches. Pull them up and to the rear torelease the lid.


5. To reduce wear, remove main shaft drive chains formain seed boxes.

Loss of Control Hazard:Towing at high speeds or with a vehicle that is not heavyenough could lead to loss of vehicle control. Loss of vehiclecontrol could lead to serious road accidents, injury and death.To reduce the hazard, do not exceed 20 mph (30 kph).

Field Operation1. Hitch drill to a suitable tractor (page 14).

For model 3P605NT or 3P606NT, continue at step 5.

2. Raise drill. Hold at raised for several seconds tore-phase lift cylinders. Set circuit to Neutral. Shut offtractor.

Refer to Figure 16 page 23 and Figure 15 on page 23

3. Remove transport lock channels from cylinder rods.Move them to storage and re-pin. See page 22.

Refer to Figure 20

4. Engage drive with lock-out hub on the left gaugewheel. Pull pin away from hub. Rotate 90.Release into deeper notch pair.

Pin may not seat fully immediately, but will at next drillmovement.

5. Set seed population per rate chart and calibration,from Seed Rate manual.

6. Load box with clean seed.

7. Raise drill. Using calibration crank1 or 3-point gaugewheel, operate the meter drive system. Check thatfeed cups, seed tubes and drives are workingproperly and free from foreign material by looking forseed flow under each opener.

8. Lower drill. With a 3-point model, set hitch to Float.

9. Pull forward. Stop. Check tool bar height and openerdepth.

10. Begin seeding.

11. Always lift drill out of the ground when turning at rowends and for other short-radius turns. Seeding stopsautomatically as drill is raised.

Re-Phasing CylindersThe lift cylinders may, after a period of time, get out oftime or phase. The effects of this can be seen when oneside of the drill is running too low or too high because itslift cylinder is either over extended or not retractedcompared to the other lift cylinder.

To re-phase the cylinders, raise drill completely and holdtractor hydraulic lever on for a few seconds to givecylinders time to re-phase.

Each time drill is raised out of ground momentarilyreverse hydraulic lever immediately after re-phasing toallow cylinders to retract about 1/2 in. (2.5 cm). Thishelps maintain a level drill.

Having cylinders become gradually out of time isdifferent than having air trapped in the system, aproblem remedied by bleeding (page 46).

1. A calibration crank kit (page 53) is available for drills manufactured prior to 2005-10-01.

Machine Damage Risk:Never back up with openers in the ground. Seed tube andfirmer damage is likely. Seed tube plugging is almost certain.Always raise the drill when stopped and prior to reversing.

Acremeter OperationAn electronic acremeter is standard on Models 3P606NTand 606NT. It is available as an accessory for Models3P605NT and 605NT. You may have any of threedifferent meter styles.

The acremeter counts shaft rotations whenever the shaftis rotating - this is with the drill lowered and in motion orduring crank operation. The meter is programmed todisplay rotations as acres or hectares, when using allrows, factory-specified tires and tire inflations.

Unusual conditions and/or non-standard rowspacings can cause the acremeter tally to vary fromactual acres planted.

3P605NT, 3P606NT, 605NT & 606NT Table of Contents Index Adjustments 30

Adjustments

To get full performance from your drill, you need anunderstanding of all component operations, and manyprovide adjustments for optimal field results. Some ofthese have been covered earlier in this manual.

Even if your planting conditions rarely change, someitems need periodic adjustment due to normal wear.

Planting Depth

Setting nominal planting depth, and achieving itconsistently, is affected by multiple adjustable drillfunctions. From greatest to least effect they are:

• Opener depth (press wheel height)

• Coulter depth

• Opener down-pressure (spring)

• Opener frame down-force (optional weights)

• Row unit down-pressure spring

• Opener (tool bar) height

• Disc blade adjustments (as discs wear)

Seed Rates

Seeds are applied by fluted feed meters driven by the leftend or center gauge wheel. Independent mechanismscontrol the rate for each box. Changing one rate doesnot affect the rate of other boxes.

Rate setting details are in Seed Rate manual 151-122B.

Main Box seed rate is controlled by adjustments for:

• Drive Type gearbox lever

• Rate handle at seed box (drill front)

• Feed Cup Door handle (one each seed tube)Native Grass (Option) Seed rate is controlled by:

• Sprocket pairings at drill front

• Rate Reduction kit (if used)Small Seeds (Option) rate is controlled by a RateHandle (drill rear).

Frame Weight AdjustmentIn some challenging no-till conditions, the drill may nothave enough weight to enable consistent coulter soilpenetration. In such cases, additional weight may help.

An optional weight bracket kit is available. See page 59for ordering information. The kit includes two brackets .The kit itself adds 180 pounds (82 kg) to the drill. Itaccepts up to 600 pounds (272 kg) of standard tractorweights (300 pounds on each bracket), for a maximum of780 pounds (354 kg) additional weight.

See table at right for available down-force per coulter,with various drill and weight kit configurations.

Possible Transport Hazard:Re-check that the tractor or towing vehicle is adequate fortransport, particularly with a 3-point drill. Considertransporting without weights on the drill. A weight kit withmaximum weights can increase empty drill weight by 34%.

Tractor Damage/Field Results Risks:With weights installed, re-check that the tractor is adequate topull the drill afield. A tractor that was marginal with thestandard drill may provide inadequate performance withaccessory weights.

Always install equal weight on each bracket. Unbalancedweights causes uneven furrow and seeding depth across thedrill.

The maximum number of tractor weights may vary byweight style and supplier.

After installing weights, re-check frame height and level(page 17), coulter depth (page 32) and opener discdepth (page 39).

Coulter AdjustmentsRefer to Figure 29

A no-till coulter , is mounted directly ahead of eachopener on the drill. The coulters cut through heavy trashand make a groove in the soil for the openers.

The coulter is designed to operate with its spring at fullextension. The spring is briefly compressed as the discencounters and rides over difficult obstructions.

Coulter DepthGreat Plains recommends operating at a tool bar heightof 243/4 in. (62.9 cm). Small adjustments may berequired for unusual seeding depths and as coulter discswear. If the coulters are not reaching desired depth (andthe springs are uncompressed), the drill may need moreweight (page 31).

Drill-wide coulter depth is controlled by tool bar height.The coulters are mounted on the drill frame. Groupcoulter cutting depth changes as the drill height is raisedand lowered.

When the opener frames are running level, theopener disc depth is 1/4 in. (6 mm) above coulterdepth.

Tool bar height is set by the tractor hitch for 3-point drills,and by cylinder depth stop (page 18) for pull-type drills.Individual Coulter Depth


Individual coulter depth may be adjusted by raising andlowering the spring bar .

1. Determine the new coulter depth desired, and/or thedifference between that and the current depth.

2. Raise the drill until the coulter discs are just touchingthe ground. The press wheels are supporting somerow unit weight at this point.

3. Measure the current spring bar length , frombottom of tool bar to bottom of spring bar. Forreference, the factory setting is:

121/21/8 in. (31.83 mm)

Determine the new bar length required.

4. Loosen the clamp bolts . Use a mallet to adjust thebar height. Tighten the clamp bolts to Grade 5 torquespecification.

Coulter Down-ForceRefer to Figure 31

Coulter springs are preset at:10 in. (25.4 cm)

giving coulters an initial maximum operating force of400 pounds (181 kg). This setting is adequate for manydifficult no-till conditions.

Machine Damage Risk:Resetting coulter-spring length shorter than 93/4 in. (24.8 cm)inches may contribute to a premature failure of parts notcovered by warranty. If additional force is needed, add weightsto drill (page 31).

For lighter no-till conditions where rocks or otherobstructions are a problem, you can lengthen coultersprings to protect coulters from impact. Refer to table atright.

1. Measure current spring length.

2. Loosen or remove jam nut .

3. Rotate adjust nut to set spring length.

4. Tighten set jam nut.

Drive Clutch Adjustment(Models 606NT and 605NT only)

Refer to Figure 32

The main drive clutch on a pull-type drill is amechanical-release, jaw-style design. You may need toadjust the clutch for proper engagement anddisengagement.

When properly adjusted, the cam plates disengage theclutch jaws completely when the drill is raised. Whenlowered in field position, clutch jaws should be engaged.

To adjust, loosen bolts on clutch tab . Slide tab up ordown to change point at which cam plates meet. Whensatisfied with adjustment, tighten bolts on clutch tab.

05/06 Series Row Unit AdjustmentsRefer to Figure 31 (which depicts an 06 Series row unit populated with most optional accessories)

From front to back, an 05/06 Series row unit (opener)can include the following capabilities (some optional):

1. Coulter (standard)This is not part of the opener, but is co-mounted withit on the tool bar. See “Coulter Adjustments” onpage 32.

2. Opener Discs (standard)Row-unit double disc openers create the seedbedfurrow. They have adjustments for spacing. See“Disc Blade Adjustments” on page 36.

3. Main Seed Hose (standard)Seed released by the metering cups is gravity fed bythe hose to the seed tube (not shown) between theopener discs. The hose and seed tube require noadjustments.

4. Down-Pressure Springs (standard)Two springs per row provide the primary force on theopener discs. The spring setting may needadjustment for challenging soil conditions and/or forchanges in coulter depth. See “Opener Spring” onpage 35

5. Inside Scraper (standard)This feature helps prevent soil buildup on the insidesurfaces of the opener discs, allowing them to meetsharply and prepare a crisp seed furrow. See “DiscScraper Adjustment” on page 37.

6. Seed Firmer (seed flap standard)A seed firmer confines seed bounce and can pressthe seed into the furrow. The standard seed flaprequires1 no adjustments. See “Seed FlapReplacement” on page 44. Optional Keeton® orSeed-Lok® firmers do have adjustments. See “SeedFirmer Adjustments” on page 38.

7. Option Seed Hose(s) (optional)If Native Grass or Small Seeds options are installed,there will be one or two additional seed hoses at oraft of the springs. The Small Seeds tube may bereversed if desired. See “Seed FirmerAdjustments” on page 38.

8. Press Wheel Height (standard)The T-handle is primary control for seeding depth.See “Opener Depth (Press Wheel Height)” onpage 39. The press wheels have no otheradjustments, but a choice of press wheel styles andsizes is available. Consult your dealer.

1. The seed flap may need to be shortened in length if an optional Keeton® or Seed-Lok® firmer is installed.

Machine Damage Risk:Never back up with row units on or in the ground. Seed tubeswill plug or be seriously damaged. Raise the drill for allreverse and short radius turns, and when stopping whilefacing up hill.

Opener SpringOpener springs provide the down pressure necessary foropener discs to open a seed trench. The springs allowthe openers to float down into depressions and up overobstructions.

Each opener spring can be adjusted for down pressure.This is useful when planting in tractor tire tracks.

If coulter depth is altered for a row, the springpre-compression needs to be changed to compensatefor the change in row unit operating height.


To adjust the pressure, remove “W” clip at bottom ofspring. Place “W” clip in a higher hole in spring rod formore pressure or in a lower hole for less pressure.

Use this adjustment only for a few rows, typically in tiretracks.

Do not set row force higher on all rows. Instead usecoulter adjustments (page 32) and frame weightadjustments (page 31).

Re-check drill level (page 17) after adjusting row force.

Disc Blade AdjustmentsRaise drill and block it up or lock it up.

Opener Disc Spacing

Sharp Object Hazard:Be careful working around and handling disc blades. Weargloves. Edges of both new and well-worn blades can be sharp.

Opener disc angle and stagger is not adjustable, butdisc-to-disc spacing is, and may need attention as discsexperience normal wear. Spacers must be reset whenblades are replaced.

Refer to Figure 36

The ideal spacing causes the blades to be in contact forabout one inch. If you insert two pieces of paper betweenthe blades, the gap between them should be0 to 1.75 in. (0 to 4.4 cm)

If the blades do not touch, they should at least be closeenough so that a business card encounters some friction when passing between them.

If the contact region is significantly larger or the gap toowide, it needs to be adjusted by moving one or morespacer washers. If the contact region varies with bladerotation, one or both blades is likely bent and in need ofreplacement. If removing all spacers cannot bring theblades into contact, they are worn out and needreplacing.

Adjusting Disc Contact

Refer to Figure 37

1. Remove the bolt retaining the opener disc on oneside. Carefully remove the disc, noting how manyspacers are outside the disc and inside the disc.Do not lose the hub components and dust cap .

It is not necessary to remove the hub flange orbearing for this adjustment.

2. To reduce the spacing between the discs (the normalcase), move one spacer washer from the inside tothe outside of the disc. It may be necessary toloosen the scraper (page 37) to reduce disc-to-discspacing.

3. Re-assemble and check disc contact.

4. Re-adjust scraper.

Disc Scraper AdjustmentTo keep opener discs turning freely, dirt scrapers aremounted between discs to clean as the discs rotate. Asfield conditions vary, scrapers may need to be adjusted.In damp conditions, scrapers may need to be lowered. Ifopeners are not turning freely, scrapers may need to beraised.

Re-adjust scrapers when replacing discs or adjustingdisc spacing.

Refer to Figure 38

To adjust scrapers, loosen 3/8 inch bolt shown in andmove scraper as needed.

Seed Firmer AdjustmentsStandard 05/06 Series row units include a seed flap.An optional Seed-Lok® or Keeton® seed firmer may beordered separately.

The seed flap requires no adjustment, but may need tobe replaced if worn, and may need to be shortened if anoptional seed firmer is added after initial delivery. Seealso “Seed Flap Replacement” on page 44.

Sharp Object Hazard:Use caution when making adjustments in this area. Row unitdisc blades may be sharp. To adjust the Keeton® Seed Firmer,lower the drill until the discs of the row units are resting on theground.

Seed-Lok® Lock-Up (Option)

Optional Seed-Lok® firming wheels provide additionalseed-to-soil contact. The wheels are spring loaded anddo not require adjusting. In some wet and stickyconditions the wheels may accumulate soil. To avoidproblems associated with this, you can lock-up thefirmers.

Refer to Figure 39 (shown with an opener disc removed for clarity - this task can be performed with discs mounted)

To lock up Seed-Lok® wheels:

1. Pull catch wire aside.

2. Pull firming-wheel arm up and release wire to catch arm.

Keeton® Seed Firmer Adjustment (Option)

The optional Keeton® Seed Firmer is an engineeredpolymer shape that slides down the seed trench. It trapsseeds as they exit the seed tube and firms them into thebottom of the furrow “V”.

Refer to Figure 40

The Firmer is provided with a preset tension which isrecommended for using the first year. The tensionscrew can be tightened in subsequent years accordingto your needs. Firmers should provide just enoughtension to push seeds to the bottom of the trench.

Small Seeds Tube Adjustment (Option)Refer to Figure 41

On a drill with the Small Seeds option, deeper seedplacement may be achieved by rotating the seed tubeto face forward.

This orientation is suggested only if the seed firmer is aseed flap. If a Keeton® or Seed-Lok® is present, seedfalls on the firmer and may be scattered rather thanplaced deeper.

Opener Depth (Press Wheel Height)A press wheel attached to each opener body controlsseeding depth . To maintain consistent depth, therelationship between the bottom of the opener discs andpress wheel is fixed upwardly by an adjustable stop oneach opener.

The press wheels also close the seed trench and gentlypress soil over seed. To provide consistent soil firming,press wheels are free to move down from normaloperating position. This maintains pressing action even ifopener discs encounter obstructions or hard soil.

To adjust, first raise openers slightly, then lift and slideT handles on top of openers Adjust all press wheels tothe same height.

• Each increment of the handle adjusts the seeding

depth by approximately 1/8 in. (6.3 mm). The range

is approximately 0 to 31/2 in. (0-89 mm) seedingdepth.

• For more shallow seeding, slide T handlesforward toward implement.

• For deeper seeding, slide T handles backwardaway from implement.

If moving the T handle backward doesn’t cause theopener to achieve desired depth, adjust the openerframe down-force (page 35).

3P605NT, 3P606NT, 605NT & 606NT Table of Contents Index Maintenance and Lubrication 42

Maintenance and Lubrication

MaintenanceProper servicing and maintenance is the key to longimplement life. With careful and systematic inspection,you can avoid costly maintenance, downtime and repair.

Always turn off and remove the tractor key beforemaking any adjustments or performing any maintenance.

Crushing Hazard:Always have frame sufficiently blocked up when working on,and particularly under implement. You may be severely injuredor killed by being crushed under a falling implement.

High Pressure Fluid Hazard:Check all hydraulic lines and fittings before applying pressure.Use paper or cardboard, not body parts, and wear heavygloves to check for suspected leaks. Escaping fluid underpressure can have sufficient pressure to penetrate the skin.Fluid escaping from a very small hole can be almost invisible.If an accident occurs, seek immediate medical attention from aphysician familiar with this type of injury.

After using drill for several hours, check all bolts to besure they are tight.

1. Securely block drill before working on it.

2. Lubricate areas listed under “Lubrication andScheduled Maintenance” on page 48.

3. Clean any fittings that do not take grease.

4. Inflate tires as specified on “Tire Pressures” onpage 60.

5. Inspect hydraulic hoses for cuts, cracks and aging.Check fittings for evidence of leaks.

6. Replace any worn, damaged or illegible safetydecals. Order new decals from your Great Plainsdealer. See “Safety Decals” on page 6.



Drive Idler Adjustment (605NT or 606NT)Two idler sprockets are located inside the left handgauge wheel arm. They should be readjusted after thefirst 100 acres (40 hectares) of drill use. From then on,readjust at the beginning of each season.

Refer to Figure 43

1. Loosen jam nut .

2. Move front idler sprocket on top of chain, tighteningchain, by screwing in adjustment stud .

3. Tighten jam nut to maintain idler position.

Do not over-tighten stud. Insufficient slack causesexcessive wear and premature chain failure.

Seed Clean-OutMain Box Clean-Out

Refer to Figure 44, which depicts the seed cup door handle in a normal operating position.

1. Set the Seed Rate Handle to zero (0). This movesthe seed cup sprockets out of the seed path.

2. Position a tarp or bucket under each row or set ofrows to be cleaned out.

3. At the seed cup for that row, pull the door handle out of the operating detent range, and swing it downto position .

4. Open the main seed box and use a small brush tosweep seed toward seed cups set to clean-out. Ifseed does not flow freely, inspect seed cup, hoseand seed tubes for obstructions.

5. If a vacuum cleaner is available, use it to removeresidual matter.

It is not necessary to operate the seed meter drive shaftfor clean-out. With the Seed Rate set to zero, nothingmoves inside the seed cups; however, an inspection ofthe flutes for excess wear and damage does requireshaft rotation.

Set the Seed Rate Handle to 100. Raise and lock-up thedrill. Turn the seed meter jackshaft with the calibrationcrank, while another person inspects the flutes from theopen seed boxes.

Native Grass Box Clean-Out

If a suitable vacuum is available, open the Native Grassbox lid, and vacuum out remaining seed.

If too much seed remains for the vacuum, or no vacuumis available:

1. Raise and lock up the drill. Place a tarp under theNative Grass seed tubes.

2. Set the Native Grass (right gearbox) Drive Type to 4.Optionally install the smallest final Driven sprocket.

3. Install the calibration crank, and turn the drivesystem until no seed flows from Native Grass tubes.

4. Vacuum out any residual material from above.

Machine Damage Risk:Water wash-out is not recommended for the Native Grass box,particularly if seed lubricants have been used. Water maycause build-up of solidified residue. Filler material used innative grass mixes can also present problems.

Small Seeds Box Clean-Out

1. Open lid of each box and scoop out as much seed aspossible.

2. To recover remaining seed, place a collection tarpunder the small seeds tubes at the openers.

3. Raise drill.

4. Set seed rate handle to 100.

5. Rotate calibration crank or ground drive wheel untilno seed flows.

6. If a vacuum cleaner is available, remove anyresidual seed from top of meters.

Seed Flap ReplacementCurrent Drill Model FlapRefer to Figure 46

To replace a seed flap , use needle nose pliers orsimilar tool to grasp “T” top of flap. Pull upward toremove flap from metal bracket .

Push new seed flap down through metal bracketuntil flap snaps into place with “T” top resting on top ofbracket.

If a Seed-Lok® or Keeton® seed firmer is also installed, itmay be necessary to shorten the flap.

Bleeding HydraulicsCheck that tractor hydraulic reservoir is full.

The drill lifting system is equipped with re-phasing typehydraulic cylinders that require a special procedure forbleeding air from the hydraulic circuits. Read and followthis procedure carefully. Re-phasing type cylinders willnot function properly with air in hydraulic circuit.

1. Check hydraulic fluid in tractor reservoir and fillreservoir to proper level. Drill-system capacity isabout 1 gallon (4.5 liters). Add fluid to system asneeded. A low reservoir level may draw air back intothe system, causing jerky or uneven cylindermovements.

2. With drill attached to tractor, jack drill up and supportframe at ends near gauge wheels.

3. With drill raised and supported, un-pin cylinders atboth gauge wheel arms and frame. Turn cylindersrod end up. Wire or otherwise safely support rodends higher than base ends.

4. With tractor engine idling, engage tractor hydraulicsto extend cylinder rods. When cylinder rods arecompletely extended, hold remote lever on for oneminute.

5. Retract cylinders. Extend cylinders again and holdremote lever on for one more minute. Repeat thisstep two more times to completely bleed system.

6. Re-pin cylinders to drill frame and gauge wheel armwith transport cylinder locks in place. If any air still istrapped in either cylinder, the cylinder will have aspongy, erratic movement and drill will not raiseevenly. If necessary, repeat bleeding process.

7. Refill tractor hydraulic fluid reservoir to its properlevel.

High Pressure Fluid Hazard:Escaping fluid under pressure can have sufficient pressure topenetrate the skin. Check all hydraulic lines and fittings beforeapplying pressure. Fluid escaping from a very small hole canbe almost invisible. Use paper or cardboard, not body parts,and wear heavy gloves to check for suspected leaks. If anaccident occurs, seek immediate medical assistance from aphysician familiar with this type of injury.

In order to prevent trapped air pockets, rod end mustbe higher than any other part of cylinder duringbleeding operation.

After the drill is raised, a slight settling will occur dueto the action of the re-phasing cylinders.



Chain MaintenanceInitially check the drive chains after the first 10 hours ofdrill use. The slack of new chains tends to increaseduring the first few hours of operation due to seating.Thereafter, check the chains every 100 hours.

Lubricate chains any time there is a chance of moisture,and when being stored at the end of the planting season.

Chain Slack

Refer to Figure 48, which, for clarity, greatly exaggerates slack, and omits the idlers.

1. Measure the span for allowable slack:Locate the longest span of each chain (usually thespan which does not run through the idlers).

2. Determine the ideal slack:Long chains (over 36 inches / 91 cm):

1/4 in. per ft (21 mm/m)Vertical short chains:

1/4 in. per ft (21 mm/m)Horizontal short chains:

1/2 in. per foot (42 mm/m).

3. Measure the current slack :Acting at a right angle to the chain span at the centerof the span, deflect the chain in both directions. Theslack is the distance of the movement.

4. Adjust the idlers for ideal slack.

Whenever mounting a chain, make sure the clip at theremovable link is oriented to minimize snags.

Refer to Figure 49 (arrow shows chain direction)

Install clip with open end facing away from direction ofchain travel (shown by gray or striped arrows in chainrouting diagrams).

Gearbox MaintenanceThe gearbox is lubricated and sealed at the factory.Under normal conditions, it does not requiremaintenance or lubrication.

If the gearbox has been opened for repair, repack allgears and around shaft bearings using at least7 oz. (200 mL) of gear lube, Great Plains Part No.788067.

Keep moisture and dirt out of gearbox. Inspect (replace ifneeded) the rubber seals on gearbox drive and shiftershafts.

Spread a small skim coat of anaerobic sealant(Loctite®1 525 or equivalent) to gear case matingsurfaces before bolting them back together.
