Important Safety Information

Look for Safety Symbol

The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety involved and extra safety precaution must be taken. When you see this symbol, be alert and carefully read the message that follows it. In addition to design and conﬁguration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.

Be Aware of Signal Words

Signal words designate a degree or level of hazard seriousness.

DANGER, and the color Safety Red, indicate an imminent hazard which, if not avoided, will result in death or serious injury. This signal word is limited to the most extreme situations, typically for machine components that, for functional purposes, cannot be guarded.

WARNING, and the color Safety Orange, indicate a potential hazard which, if not avoided, could result in death or serious injury, and includes hazards that are exposed when guards are removed. It may also be used to alert against unsafe practices.

CAUTION, and the color Safety Yellow, indicate a potential hazard which, if not avoided, may result in minor or moderate injury. It may also be used to alert against 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, hospital

and 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 illegible

decals.

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 cause

hearing impairment or hearing loss, wear suitable hearing protection such as earmuffs or earplugs.

▲ Because operating equipment safely requires your full

attention, avoid wearing entertainment headphones while operating machinery.

Handle Chemicals Properly

Agricultural chemicals can be dangerous. Improper use can seriously injure persons, animals, plants, soil and property.

▲ Do not use liquid seed treatments with the 3P606NT or

606NT.

▲ 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 by

chemical manufacturer.

▲ Dispose of empty chemical containers properly. Laws

generally 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 before disconnecting

hydraulic lines.

▲ Use a piece of paper or cardboard, NOT BODY PARTS, to

check for suspected leaks.

▲ Wear protective gloves and safety glasses or goggles when

working with hydraulic systems.

Great Plains Manufacturing, Inc. Table of Contents Index Important Safety Information 3

Use an Adequate Tractor

Model 3P605NT or 3P606NT only:

▲ Ensure that the tractor is rated for, and correctly ballasted

for the drill’s 3-point loading. Check that drill plus ballast does 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

(including the weight of any Options and materials).

▲ Avoid transport with material loaded in boxes.

⁄3(67%) of the drill

Use A Safety Chain

(Model 605NT or 606NT only)

▲ Use a safety chain to help control drawn machinery should

it separate from tractor drawbar.

▲ Use a chain with a strength rating equal to or greater than

the gross weight of towed machinery.

▲ Attach chain to tractor drawbar support or other speciﬁed

anchor location. Allow only enough slack in chain to permit turning.

▲ Replace chain if any links or end ﬁttings are broken,

stretched or damaged.

▲ Do not use safety chain for towing.

Keep Riders Off Machinery

Riders obstruct the operator’s view. Riders could be struck 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 Devices

Slow-moving tractors and towed implements can create a hazard when driven on public roads. They are difﬁcult to see, especially at night.

▲ Use ﬂashing warning lights and turn signals whenever

driving on public roads.

▲ Use lights and devices provided with implement

Transport Machinery Safely

Maximum transport speed for the implement on its own tires is 20 mph (30 kph). Rough terrain may require a slower speed. Sudden braking can cause a towed load to swerve and upset.

▲ Do not exceed 20 mph (30 kph). Travel only at a speed

which allows adequate control of steering and stopping.

▲ Comply with state and local laws.

▲ Carry reﬂectors or ﬂags to mark drill in case of breakdown

on the road.

▲ 3-point implements reduce weight on steering tires. Verify

that tractor is correctly ballasted. Watch for signs of poor steering traction.

Shutdown and Storage

▲ Park on level ground.

▲ Unhitch and store the drill in an area where children

normally do not play.

Tire Safety

Tire changing can be dangerous and should be performed by trained personnel using correct tools and equipment.

▲ When inﬂating tires, use a clip-on chuck and extension hose

long enough for you to stand to one side–not in front of or over tire assembly. Use a safety cage if available.

▲ When removing and installing wheels, use wheel-handling

equipment adequate for weight involved.

Introduction

Great Plains welcomes you to its growing family of new product owners. Your 6-Foot No-Till Drill has been designed with care and built by skilled workers using quality materials. Proper setup, maintenance, and safe operating practices will help you get years of satisfactory use from the machine.

Description of Unit

The 3P605NT and 3P606NT are 3-point seeding implements. The 605NT and 606NT are towed seeding implements. This drill has a working width of 7.5 feet (1.9 m). The drill has straight arm, double disc 05 or 06 Series openers. The opener discs make a seed bed, and seed tubes mounted between the discs place seed in the furrow. Press wheels following the opener discs close the furrow and gauge opener seeding depth. A T-handle on the opener body makes seeding depth adjustments.

The metering system is driven from the gauge wheel (3-point), or from the left end wheel (pull-type). Seeding rates are set by rate adjustment handles and a Drive Type gearbox for the main seed box.

Adjusting 3-Point Height

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

Note: Do not lower coulters to aid in penetrating hard soil.

Instead, increase coulter down-force (page 32). This may require adding optional weight (page 30).

Refer to Figure 10

Height Setup: Model 605NT or 606NT

Set Tool Bar Height

Refer to Figure 11 and Figure 12

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

The suggested initial tool bar operating height is:

243⁄4in. (62.9 cm) from the base of the opener tool bar to the ground, when lowered in ﬁeld conditions (opener discs in ground).

1. Use the tractor remote circuit to raise the drill to the

full extension of both lift cylinders. Hold the drill raised for several seconds to re-phase the cylinders. Remove any transport locks.

2. In ﬁeld conditions, lower the drill to the desired tool

bar 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 stop

weldment to the cylinder rod.

4. Slide the weldment up the rod until it contacts the

valve actuator , then slide it up another

⁄8in. (3 mm). Tighten the bolt.

5. Start the tractor. Raise and lower the drill. Pull

forward in ground. The lowering stops when the weldment moves the actuator a short distance. Shut off the tractor and verify the tool bar height.

Note: If further adjustment is required, the drill height

changes at approximately half the change in weldment position. For example, raising the drill another1⁄8in. (3 mm) would require moving the weldment up another1⁄4in. (6 mm).

Level Model 605NT or 606NT

Refer to Figure 13

1. Use hitch turnbuckle to level drill.

2. Lower unit to take weight off of drill. Do not adjust

with unit in raised position.

3. Loosen jam nuts on hitch turnbuckle.

4. Turn turnbuckle to shorten or lengthen until top of

drill frame is parallel to the ground being careful not to extend clevises beyond turnbuckle.

5. Retighten jam nuts on turnbuckle.

Operation Instructions

This section covers general operating procedures. Experience, machine familiarity and the following information will lead to efﬁcient operation and good working habits. Always operate farm machinery with safety in mind.

Pre-Start Checklist

High Pressure Fluid Hazard:

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

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

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

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

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

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

6. Check hydraulic hoses, ﬁttings and cylinders for leaks. Repair or replace faulty parts before going to the ﬁeld.

7. Rotate both drive wheel to verify that the drive and meters are working properly and free from foreign material.

WARNING

Falling Hazard:

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

2014-02-10 Table of Contents Index 151-061M

To avoid serious injury or death:

Watch your step when climbing ladder or walking on walkboard.

Transporting 3P605NT or 3P606NT

Transport considerations are different for 3-point and pull-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 dangerously reduce steering authority, particularly during acceleration and ascending hills. You can lose directional control entirely, which could result in a major accident, serious injury, or death. Adding too much ballast could lead to brake or other mechanical failures, tire failures and loss of control.

▲ Ensure that the tractor is rated for, and correctly ballasted

for the drill’s 3-point loading. Check that drill plus ballast does not exceed the tractor’s capability.

▲ If the drill has accessory weight brackets, consider moving

any tractor weights present to the tractor during transport.

▲ Avoid transport with material loaded in boxes.

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

Use Transport Locks

Transport Hazard:

Failure of hydraulic cylinders during transport causes drill to drop suddenly, which could lead to a serious accident, injury or death. To prevent an accident, always install cylinder locks before 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 wheel hydraulic lift cylinders.

1. Raise drill completely. Set circuit to Neutral.

2. Remove lock channels from storage locations.

3. Place lock channels over rod of cylinder.

4. Install cylinder lock pins and retainer clips .

Note: The cylinder lock can be secured or removed only

after the drill is fully raised.

5. Unload drill box. The drill can be transported with a full box of grain, but the added weight increases stopping distance and decreases maneuverability. Unload drill box before transporting if at all possible.

Transport Cautiously

Keep 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 laws when traveling on public roads.

Reduce speed on rough roads.

Loss of Control Hazard:

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

Loading Seed

Possible Chemical Hazard:

Take all prescribed material safety precautions.

Fully loaded with dense seed, the drill weighs an additional 1155 lbs (529 kg). Include this weight when checking tractor capability.

The drill must be hitched for seed loading.

Load slightly more material than needed, because consumption rates can vary between compartments even though the furrow rates are identical.

1 2

Main Seed Box Loading

1. Check that all meter doors are positioned for the seed size, and not set for clean-out. See “Position Seed Cup Doors” in seed Rate Manual. If loading prior to transport, set them to position 1 (smallest seed).

2. Install or remove optional seed plugs as desired for the row spacing planned. Refer to Seed Rate Manual.

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

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

4. Load seed evenly into compartments.

To reduce wear on unused boxes that may also be present:

• Remove ﬁnal drive chain for Small Seed box.

• Remove any Native Grass chain.

Figure 19

Native Grass Box Open

28362

Loading Native Grass Box

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

2. Load seed evenly into compartments.

3. Add1⁄3cup (80 mL) graphite seed lubricant on top of the loaded seed. In humid conditions, double or triple this amount as needed.

Loading Small Seeds Box

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

2. Take all necessary materials safety precautions if the seed is treated.

3. The Small Seeds lid is held closed by two external rubber latches. Pull them up and to the rear to release the lid.

4. Load seed evenly into compartments.

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

151-061M Table of Contents Index 2014-02-10

Field Operation

1. 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 to re-phase lift cylinders. Set circuit to Neutral. Shut off tractor.

Refer to Figure 16 page 22 and Figure 15 on page 22

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 gauge wheel. Pull pin away from hub. Rotate 90°. Release into deeper notch pair.

Note: Pin may not seat fully immediately, but will at next

drill movement.

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

6. Load box with clean seed.

7. Raise drill. Using calibration crankaor 3-point gauge gauge wheel, operate the meter drive system. Check that feed cups, seed tubes and drives are working properly and free from foreign material by looking for seed 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 opener depth.

10. Begin seeding.

11. Always lift drill out of the ground when turning at row ends and for other short-radius turns. Seeding stops automatically as drill is raised.

Figure 20

Lock-Out Hub Engaged

Machine Damage Risk:

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

18480

Re-Phasing Cylinders

The lift cylinders may, after a period of time, get out of time or phase. The effects of this can be seen when one side of the drill is running too low or too high because its lift cylinder is either over extended or not retracted compared to the other lift cylinder.

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

Each time drill is raised out of ground momentarily reverse hydraulic lever immediately after re-phasing to allow cylinders to retract about1⁄2in. (2.5 cm). This helps maintain a level drill.

Note: Having cylinders become gradually out of time is

different than having air trapped in the system, a problem remedied by bleeding (page 46).

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

Acremeter Operation

An electronic acremeter is standard on Models 3P606NT and 606NT. It is available as an accessory for Models 3P605NT and 605NT. You may have any of three different meter styles.

The acremeter counts shaft rotations whenever the shaft is rotating - this is with the drill lowered and in motion or during crank operation. The meter is programmed to display rotations as acres or hectares, when using all rows, factory-speciﬁed tires and tire inﬂations.

Note: Unusual conditions and/or non-standard row

spacings can cause the acremeter tally to vary from actual acres planted.

Adjustments

To get full performance from your drill, you need an understanding of all component operations, and many provide adjustments for optimal ﬁeld results. Some of these have been covered earlier in this manual.

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

Planting Depth

Setting nominal planting depth, and achieving it consistently, is affected by multiple adjustable drill functions. 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 left end or center gauge wheel. Independent mechanisms control the rate for each box. Changing one rate does not 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 Rate Handle (drill rear).

Frame Weight Adjustment

In some challenging no-till conditions, the drill may not have enough weight to enable consistent coulter soil penetration. In such cases, additional weight may help.

An optional weight bracket kit is available. See page 59 for ordering information. The kit includes two brackets .

The kit itself adds 180 pounds (82 kg) to the drill. It accepts up to 600 pounds (272 kg) of standard tractor weights (300 pounds on each bracket), for a maximum of 780 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 for transport, particularly with a 3-point drill. Consider transporting without weights on the drill. A weight kit with maximum weights can increase empty drill weight by 34%.

Tractor Damage / Field Results Risks:

With weights installed, re-check that the tractor is adequate to pull the drill aﬁeld. A tractor that was marginal with the standard drill may provide inadequate performance with accessory weights.

Always install equal weight on each bracket. Unbalanced weights causes uneven furrow and seeding depth across the drill.

Note: The maximum number of tractor weights may vary

by weight style and supplier.

After installing weights, re-check frame height and level (page 17), coulter depth (page 31) and opener disc depth (page 38).

Coulter Adjustments

Refer to Figure 29

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

The coulter is designed to operate with its spring at full extension. The spring is brieﬂy compressed as the disc encounters and rides over difﬁcult obstructions.

Coulter Depth

Great Plains recommends operating at a tool bar height

⁄4in. (62.9 cm). Small adjustments may be

of 24 required for unusual seeding depths and as coulter discs wear. If the coulters are not reaching desired depth (and the springs are uncompressed), the drill may need more weight (page 30).

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

Note: When the opener frames are running level, the

opener disc depth is depth.

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

Refer to Figure 29 and Figure 30

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

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

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

3. Measure the current spring bar length , from bottom of tool bar to bottom of spring bar. For reference, the factory setting is:

121⁄2±1⁄8in. (31.8±3 mm)

Determine the new bar length required.

4. Loosen the clamp bolts . Use a mallet to adjust the bar height. Re-tighten the clamp bolts to Grade 5 torque speciﬁcation.

Machine Damage Risk:

Resetting coulter-spring length shorter than 93⁄4in. (24.8 cm) inches may contribute to a premature failure of parts not covered by warranty. If additional force is needed, add weights to drill (page 30).

For lighter no-till conditions where rocks or other obstructions are a problem, you can lengthen coulter springs to protect coulters from impact. Refer to table at right.

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 a mechanical-release, jaw-style design. You may need to adjust the clutch for proper engagement and disengagement.

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

To adjust, loosen bolts on clutch tab . Slide tab up or down to change point at which cam plates meet. When satisﬁed with adjustment, retighten bolts on clutch tab.

05/06 Series Row Unit Adjustments

Refer 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 with it on the tool bar. See “Coulter Adjustments” on page 31.

2. Opener Discs (standard) Row-unit double disc openers create the seedbed furrow. They have adjustments for spacing. See “Disc Blade Adjustments” on page 35.

3. Main Seed Hose (standard) Seed released by the metering cups is gravity fed by the hose to the seed tube (not shown) between the opener discs. The hose and seed tube require no adjustments.

4. Down-Pressure Springs (standard) Two springs per row provide the primary force on the opener discs. The spring setting may need adjustment for challenging soil conditions and/or for changes in coulter depth. See “Opener Spring” on page 34

5. Inside Scraper (standard) This feature helps prevent soil buildup on the inside surfaces of the opener discs, allowing them to meet sharply and prepare a crisp seed furrow. See “Disc Scraper Adjustment” on page 36.

6. Seed Firmer (seed ﬂap standard) A seed ﬁrmer conﬁnes seed bounce and can press the seed into the furrow. The standard seed ﬂap requires Replacement” on page 45. Optional Keeton® or Seed-Lok®ﬁrmers do have adjustments. See “Seed Firmer Adjustments” on page 37.

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 or aft of the springs. The Small Seeds tube may be reversed if desired. See “Seed Firmer Adjustments” on page 37.

8. Press Wheel Height (standard) The T-handle is primary control for seeding depth. See “Opener Depth (Press Wheel Height)” on page 38. The press wheels have no other adjustments, but a choice of press wheel styles and sizes is available. Consult your dealer.

Opener Spring

Opener springs provide the down pressure necessary for opener discs to open a seed trench. The springs allow the openers to ﬂoat down into depressions and up over obstructions.

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 spring pre-compression needs to be changed to compensate for the change in row unit operating height.

Refer to Figure 34 and Figure 35

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

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

Do not set row force higher on all rows. Instead use coulter adjustments (page 31) and frame weight adjustments (page 30).

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

Disc Blade Adjustments

Raise drill and block it up or lock it up.

Opener Disc Spacing

Sharp Object Hazard:

Be careful working around and handling disc blades. Wear gloves. Edges of both new and well-worn blades can be sharp.

Opener disc angle and stagger is not adjustable, but disc-to-disc spacing is, and may need attention as discs experience normal wear. Spacers must be reset when blades are replaced.

Refer to Figure 36

The ideal spacing causes the blades to be in contact for about one inch. If you insert two pieces of paper between the blades, the gap between them should be

0 to 1.75 in. (0 to 4.4 cm) If the blades do not touch, they should at least be close enough so that a business card encounters some friction when passing between them.

If the contact region is signiﬁcantly larger or the gap too wide, it needs to be adjusted by moving one or more spacer washers. If the contact region varies with blade rotation, one or both blades is likely bent and in need of replacement. If removing all spacers cannot bring the blades into contact, they are worn out and need replacing.

Adjusting Disc Contact

Refer to Figure 37

1. Remove the bolt retaining the opener disc on one

side. Carefully remove the disc, noting how many spacers are outside the disc and inside the disc. Do not lose the hub components and dust cap .

Note: It is not necessary to remove the hub ﬂange or

bearing for this adjustment.

2. To reduce the spacing between the discs (the normal

case), move one spacer washer from the inside to

the outside of the disc. It may be necessary to loosen the scraper (page 36) to reduce disc-to-disc spacing.

3. Re-assemble and check disc contact.

4. Re-adjust scraper.

Disc Scraper Adjustment

To keep opener discs turning freely, dirt scrapers are mounted between discs to clean as the discs rotate. As ﬁeld conditions vary, scrapers may need to be adjusted. In damp conditions, scrapers may need to be lowered. If openers are not turning freely, scrapers may need to be raised.

Re-adjust scrapers when replacing discs or adjusting disc spacing.

Refer to Figure 38

To adjust scrapers, loosen3⁄8inch bolt shown in and

move scraper as needed.

Seed Firmer Adjustments

Standard 05/06 Series row units include a seed ﬂap. An optional Seed-Lok ordered separately.

The seed ﬂap requires no adjustment, but may need to be replaced if worn, and may need to be shortened if an optional seed ﬁrmer is added after initial delivery. See also “Seed Flap Replacement” on page 45.

Sharp Object Hazard:

Use caution when making adjustments in this area. Row unit disc blades may be sharp. To adjust the Keeton lower the drill until the discs of the row units are resting on the ground.

Seed-Lok® Lock-Up (Option)

Optional Seed-Lok® ﬁrming wheels provide additional seed-to-soil contact. The wheels are spring loaded and do not require adjusting. In some wet and sticky conditions the wheels may accumulate soil. To avoid problems associated with this, you can lock-up the ﬁrmers.

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 engineered polymer shape that slides down the seed trench. It traps seeds as they exit the seed tube and ﬁrms them into the bottom of the furrow “V”.

Refer to Figure 40

The Firmer is provided with a preset tension which is recommended for using the ﬁrst year. The tension screw can be tightened in subsequent years according

to your needs. Firmers should provide just enough tension 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 seed placement may be achieved by rotating the seed tube to face forward.

This orientation is suggested only if the seed ﬁrmer is a seed ﬂap. If a Keeton falls on the ﬁrmer and may be scattered rather than placed deeper.

or Seed-Lok® is present, seed

Opener Depth (Press Wheel Height)

A press wheel attached to each opener body controls seeding depth . To maintain consistent depth, the relationship between the bottom of the opener discs and press wheel is ﬁxed upwardly by an adjustable stop on each opener.

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

To adjust, ﬁrst raise openers slightly, then lift and slide T handles on top of openers Adjust all press wheels to the same height.

• Each increment of the handle adjusts the seeding depth by approximately1⁄8in. (6.3 mm). The range is approximately 0 to 31⁄2in. (0-89 mm) seeding depth.

• For more shallow seeding, slide T handles forward toward implement.

• For deeper seeding, slide T handles backward away from implement.

If moving the T handle backward doesn’t cause the opener to achieve desired depth, adjust the opener frame down-force (page 34).

Maintenance and Lubrication

Maintenance

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

Always turn off and remove the tractor key before making 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 injured or 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 heavy gloves to check for suspected leaks. Escaping ﬂuid under pressure 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 a physician familiar with this type of injury.

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

1. Securely block drill before working on it.

2. Lubricate areas listed under “Lubrication and

Scheduled Maintenance” on page 48.

3. Clean any ﬁttings that do not take grease.

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

page 60.

5. Inspect hydraulic hoses for cuts, cracks and aging.

Check ﬁttings for evidence of leaks.

6. Replace any worn, damaged or illegible safety

decals. Order new decals from your Great Plains dealer. See “Safety Decals” on page 6.

Drive Idler Adjustment (605NT or 606NT)

Two idler sprockets are located inside the left hand gauge wheel arm. They should be readjusted after the ﬁrst 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, tightening chain, by screwing in adjustment stud .

3. Retighten jam nut to maintain idler position.

Note: Do not over-tighten stud. Insufﬁcient slack causes

excessive wear and premature chain failure.

Seed Clean-Out

Main 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 moves the seed cup sprockets out of the seed path.

2. Position a tarp or bucket under each row or set of rows 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 down to position .

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

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

It is not necessary to operate the seed meter drive shaft for clean-out. With the Seed Rate set to zero, nothing moves inside the seed cups; however, an inspection of the ﬂutes for excess wear and damage does require shaft rotation.

Set the Seed Rate Handle to 100. Raise and lock-up the drill. Turn the seed meter jackshaft with the calibration crank, while another person inspects the ﬂutes from the open seed boxes.

Native Grass Box Clean-Out

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

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

1. Raise and lock up the drill. Place a tarp under the Native 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 drive system 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 may cause build-up of solidiﬁed residue. Filler material used in native grass mixes can also present problems.

Small Seeds Box Clean-Out

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

2. To recover remaining seed, place a collection tarp under 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 until no seed ﬂows.

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

Bleeding Hydraulics

Check that tractor hydraulic reservoir is full.

The drill lifting system is equipped with re-phasing type hydraulic cylinders that require a special procedure for bleeding air from the hydraulic circuits. Read and follow this procedure carefully. Re-phasing type cylinders will not function properly with air in hydraulic circuit.

1. Check hydraulic ﬂuid in tractor reservoir and ﬁll reservoir to proper level. Drill-system capacity is about 1 gallon (4.5 liters). Add ﬂuid to system as needed. A low reservoir level may draw air back into the system, causing jerky or uneven cylinder movements.

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

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

4. With tractor engine idling, engage tractor hydraulics to extend cylinder rods. When cylinder rods are completely extended, hold remote lever on for one minute.

5. Retract cylinders. Extend cylinders again and hold remote lever on for one more minute. Repeat this step two more times to completely bleed system.

6. Re-pin cylinders to drill frame and gauge wheel arm with transport cylinder locks in place. If any air still is trapped in either cylinder, the cylinder will have a spongy, erratic movement and drill will not raise evenly. If necessary, repeat bleeding process.

7. Reﬁll tractor hydraulic ﬂuid reservoir to its proper level.

High Pressure Fluid Hazard:

Note: In order to prevent trapped air pockets, rod end

must be higher than any other part of cylinder during bleeding operation.

Note: After the drill is raised, a slight settling will occur

due to the action of the re-phasing cylinders.

Chain Maintenance

Initially check the drive chains after the ﬁrst 10 hours of drill use. The slack of new chains tends to increase during 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 the span which does not run through the idlers).

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

⁄4in. per ft (21 mm/m)

Vertical short chains:

⁄4in. per ft (21 mm/m)

Horizontal short chains:

⁄2in. per foot (42 mm/m).

3. Measure the current slack :

Acting at a right angle to the chain span at the centre of the span, deﬂect the chain in both directions. The slack is the distance of the movement.

4. Adjust the idlers for ideal slack.

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

Refer to Figure 49 (arrow shows chain direction)

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

Gearbox Maintenance

The gearbox is lubricated and sealed at the factory. Under normal conditions, it does not require maintenance or lubrication.

If the gearbox has been opened for repair, repack all gears and around shaft bearings using at least 7 oz. (200 mL) of gear lube, Great Plains Part No.

788067.

Keep moisture and dirt out of gearbox. Inspect (replace if needed) the rubber seals on gearbox drive and shifter shafts.

Spread a small skim coat of anaerobic sealant (Loctite®a525 or equivalent) to gear case mating surfaces before bolting them back together.

Machine Damage Risk:

Use sealant sparingly. Excess sealant may squeeze off the intended surface and lock bearings or gears.
