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.

Important Safety Information

Be Aware of Signal Words

Signal words designate a degree or level of hazard seriousness.

DANGER indicates an imminently hazardous situation 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 indicates a potentially hazardous situation 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 indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices.

Transport Machinery Safely

Maximum transport speed for implement is 20 mph. Some rough terrains require a slower speed. Sudden braking can cause a towed load to swerve and upset.

▲ Do not exceed 20 mph. Never travel at a

speed which does not allow adequate control of steering and stopping. Reduce speed if towed load is not equipped with brakes.

▲ Comply with state and local laws.

▲ Do not tow an implement that, when fully

loaded, weighs more than 1.5 times the weight of towing vehicle.

▲ Carry reﬂectors or ﬂags to mark drill in case of

breakdown on the road.

▲ Keep clear of overhead power lines and other

obstructions when transporting. Refer to transport dimensions under “Speciﬁcations and Capacities,” page 59.

Important Safety Information

cal ﬁre.

▲ Store or dispose of unused chemicals as

speciﬁed by chemical manufacturer.

Use A Safety Chain

▲ Use a safety chain to help control drawn

machinery should it separate from tractor drawbar.

Important Safety Information

▲ 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.

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

Rephasing 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 rephase the cylinders, raise drill completely and hold tractor hydraulic lever on for a few seconds to give cylinders time to rephase.

Each time drill is raised out of ground momentarily reverse hydraulic lever immediately after rephasing to allow cylinders to retract about 1/2 inch. This will help in maintaining a level drill.

NOTE: Understand that having cylinders become gradually out of time is different than having air trapped in the system from improper bleeding. Each condition is corrected differently.

Bleeding Hydraulics

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 injured, seek medical assistance from a doctor that is familiar with this type of injury.

Check that tractor hydraulic reservoir is full.

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

Preparation and Setup

1. Check hydraulic ﬂuid in tractor reservoir and ﬁll reservoir to proper level. Drill-system capacity is about 1 gallon. 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, unpin cylinders from gauge wheel arms and frame. Turn cylinders "rod end up". Wire or otherwise safely support rod ends higher than base ends.

NOTE: In order to prevent trapped air pockets, rod end must be higher than any other part of cylinder during bleeding operation.

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.

150-131M

Page 22

1205NT

6. Repin 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.

NOTE: After the drill is raised, a slight settling will occur due to the action of the rephasing cylinders.

Leveling Drill

See Figure 8.

1. Loosen locknuts (2) and adjust cylinder eyebolts (1) so there is initially about 3 1/16 inch of threads above mounting plate.

2. Raise drill with hydraulics until openers and coulters are 1 to 2 inches off the ground.

3. Measure height of coulter tube from ground on both ends of drill.

4. Adjust eyebolt to level drill from end to end.

5. Tighten nuts on eyebolts when drill is level.

Marker Operation

Optional marker attachments are available from your Great Plains dealer. Before operating markers, make sure hydraulics are properly bled as described under “Marker Adjustments”, page 38.

Dual markers equipped witha sequence valve are powered off the same hydraulic circuit. The markers cycle in the following sequence:

1. right up, left up

2. right down, left up

3. right up, left up

4. right up, left down

You can adjust marker folding speed. Refer to “Marker Adjustments”, page 38, and adjustfolding speed to a safe rate. Folding markers at high speed can damage markers.

Operating Instructions

Transporting

Loss of Control Hazard:

Towing the drill 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. Check that your tractor has enough ballast to handle the weight of the drill. Refer to your tractor operator’s manual for ballast requirements.

Loss of Control Hazard:

Failure of hydraulic cylinders during transport will cause drill to drop suddenly, which could lead to serious road accidents, injury or death. To prevent an accident, always install cylinder locks before transporting drill.

Before transporting the drill, follow and check these items:

Lock Cylinders. Cylinder locks (1) are located on both hydraulic cylinders. With drill fully raised swing lock up over rod of cylinder and snap into place, see Figure 10.

NOTE: The cylinder locks can be engaged or disengaged only after the drill is fully raised.

Page 26

1205NT

Unload drill box. The drill can be transported

with a full box of grain, but the added weight will increase stopping distance and decrease maneuverability. Unload drill box before transporting if at all possible.

Clearance. Remember that the drill is wider that the tractor. Allow safe clearance.

Road rules. Comply with all federal, state and local safety laws when traveling on public roads.

Lock-out Hub. Make sure drive lock-out hub on left side of drill is disengaged before transporting, see Figure 11. This will prevent excessive wear of drive system during transport.

Transporting with Markers

Always transport markers in the folded position.

Parking

Perform the following steps when parking the drill. Refer to “Storage”, page 48, to prepare for longterm storage.

1. Park drill on a level, solid area.

2. Lower drill until openers are resting on the ground.

3. Securely block tires to prevent rolling.

4. Remove tongue jack from storage stob. Pin jack on side of tongue. If ground is soft, place a board or plate under jack. Refer to Figure

12.

5. Extend jack until tongue weight is off tractor drawbar.

6. Unplug hydraulic hoses and wiring harness from tractor. Do not allow hose ends or harness ends to rest on the ground.

7. Remove hitch bolt and safety chain from tractor drawbar.

Adjustments

Coulter Adjustments

A no-till coulter (1), Figure 13, 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 coulters are mounted on the drill frame so coulter cutting depth changes as the drill is raised and lowered.

To set drill seeding depth, you must:

1. Set coulter depth with hydraulic stop.

2. Set opener depth with T-handles on press wheels.

Adjustments

3. If soil conditions make it necessary, increase coulter down pressure by adding weights.

If necessary, adjust individual coulters or openers to seed in tire tracks, refer to page 26.

Coulter cutting depth is controlled by a depth control valve.

The amount of coulter down force needed to cut a soil groove varies with soil conditions. Adding weight or shortening the coulter spring increases coulter down pressure and cutting force.

Coulter Depth Control

The master-slave lift cylinders on your drill control the depth of the coulters. A depth valve regulates the retracted length of these cylinders.

1. See Figure 14. Slightly raise drill with depth stop engagement arm on the rock shaft not touching the valve.

2. Turn the depth control knob clockwise. Each rotation lowers the coulters approximately 1/4 inch.

Figure 13

Coulter

13985

3. Raise and lower drill a few times to recheck depth.

NOTE: Changing depth of coulters will effect planting depth of openers. Press wheels will need to be adjusted accordingly.

Coulter Down Pressure Weights. If more weight is required for your soil

conditions, add weights to weight brackets located on box frame. No more than 1200 pounds (600 pounds per side) should ever be added. Add an equal amount of weight to each end of drill. See Ta bl e 1 .

Spring Length. Coulter springs are preset at 10 inches, giving coulters an initial operating force of 400 pounds. This setting is adequate for many difﬁcult no-till conditions.

Equipment Damage Risk:

Resetting coulter-spring length shorter than 9 3/4 inches may contribute to premature failure of parts and warranty will be voided. If additional force is needed, add weights to drill.

Weight Chart

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 2.

Individual Coulter Adjustment

Individual coulters can be lowered if coulters follow in tractor tire tracks and do not give satisfactory depth. To do so:

1. Loosen 5/8 inch jam nuts on 5/8 inch square head set screws. Then loosen set screws.

2. Lower coulter to desired depth.

3. Tighten set screw on side of coulter clamp ﬁrst. This squares coulter bar in clamp.

4. Tighten set screw on front of coulter clamp. Then tighten both 5/8 inch jam nuts on each set screw.

Opener Adjustments

Opener Down Pressure

Opener springs provide the down pressure necessary for opener disks 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 penetrating hard soil and for planting in tractor tire tracks.

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, see Figure 16.

Adjustments

12103

Opener Seeding Depth

A press wheel attached to each opener body controls seeding depth. To maintain consistent depth, the relationship between the bottom of the opener disks 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 disks encounter obstructions or hard soil.

Set opener seeding depth by adjusting presswheel height. To adjust, ﬁrst raise drill slightly, then lift and slide T-handles on top of openers as shown in Figure 17.

• For shallower seeding, slide T-handles toward drill.

• For deeper seeding, slide T-handles away from drill.

Disk Scraper Adjustment

To keep opener disks turning freely, dirt scrapers are mounted between disks to clean as the disks 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.

To adjust scrapers, loosen 3/8 inch bolt shown in Figure 18 and move scraper as needed.

Scraper bolt

Gauge Wheel Idler Adjustment

Located inside the left hand gauge wheel arm is two idler sprockets which should be readjusted after the ﬁrst 100 acres of drill use. From then on, readjust at the beginning of each season.

To adjust, move front idler sprocket on top of chain down by loosening jam nut and screwing in adjustment stud. Refer to Figure 19.

Retighten jam nut to maintain idler position.

NOTE: Do not over-tighten chains. To do so will cause excessive wear.

Seeding Rate

Calibrating the seeding rate requires four steps:

1. selecting one of four drive types,

2. setting the seed-rate handle,

3. positioning the feed-cup door, and

4. checking the seed rate.

Refer to the seed rate charts beginning on page

31. These charts list the proper drive type and seed-rate-handle settings for various seeds and seeding rates.

The seed rate charts are based on cleaned, untreated seed of average size and test weight. The rates are based on 295/75/R22.5 rib implement tires. Many factors will affect seeding rates including foreign material, seed treatment, seed size, ﬁeld conditions, tire pressure and test weight. Minor adjustments likely will be needed. Set and check the seeding rate using the procedures on page 30, then adjust the rate as necessary.

Select Drive Type

The gearbox is designed to give you a variety of drive speeds for different types of seeds and rates. It is a linear shift pattern design with constant mesh gearing and totally sealed to keep the dirt out. No lubrication is required unless service is needed.

The gearbox brass indicator plate is positioned so the side with “1” is closest to the center of the drill.

To set the gearbox move the selector handle until the desired drive type appears in the window on the handle.

Position Feed-Cup Doors

See Figure 22. For wheat and other small seeds, move feed cup door handles to highest position. For soybeans and other large seeds, lower handles to second position. If excessive seed cracking occurs, lower handles to third position. Move handles to fourth, wide-open position, for seed cup clean out. Make sure all handles are in same position before drilling.

Feed-cup door handle

NOTE: Do not open cup to wide open position with seeds in the box unless complete clean out is desired.

Check Seed Rate

NOTE: For drills built after October 1, 2005, use the gauge wheel tire or supplied calibration crank to calibrate. For drills built before Octo- ber 1, 2005, use the gauge wheel to calibrate or order the calibration crank kit available through your Great Plains Dealer.

1. To calibrate, use either the left hand gauge wheel or the supplied calibration crank. If using the calibration crank, attach crank to coupler on gauge wheel jackshaft with retaining pin and disengage lockout on drive wheel.

2. Rotate left hand gauge wheel or calibration crank to see that feed cups and drive are working properly and are free from foreign matter.

3. To adjust seeding rate, decide which drive type (gearbox) setting you need from the seeding charts beginning on page 31. Set the gearbox. Rotate drive tire or calibration crank a few turns to conﬁrm gearbox has engaged.

Figure 22

Feed-cup Door Handle Adjustment

8. Check that the three seed cups have plenty of seed coming into them.

9. Weigh metered seed. Subtract initial weight of container. Divide by three. Multiply by the number of openers on your drill to determine total pounds seeded per acre. If this ﬁgure is different than desired, set your seed rate adjustment handle accordingly.

NOTE: You may want to repeat the calibration procedure if your results vary greatly from seed rate chart.

10. When drilling, check seeding rate by noting acres drilled, amount ofseed addedto drill and seed level in drill box. If you are seeding more or less than desired, adjust seeding rate slightly to compensate for ﬁeld conditions.

Equations for calibrating seed rate:

14744

150-131M

4. Record weight of an empty container large enough to hold seed metered for one acre.

5. Place several pounds of seed over three seed cups on an outside end of drill box. Pull seed tubes off of these three openers.

6. Turn drive gauge wheel or calibration crank several times to ﬁll seed cups with seed. Turn wheel or crank until seed falls to the ground from each cup.

7. Rotate drive gauge wheel or calibration crank 346 rotations. This is equal to one acre.

NOTE: You can also rotate the gauge wheel jackshaft by means of a wrench or socket. If rotating gauge wheel jackshaft, disengage the lockout on the drive wheel and use same number of rotations as for rotating drive wheel.

Small Seeds Attachment

To set and calibrate the seeding rate on the optional small seeds attachment, follow these steps:

NOTE: For drills built after October 1, 2005, calibrate using gauge wheel or supplied calibration crank. For drills built before October 1, 2005, calibrate using gauge wheel or order the calibration crank kit available through your Great Plains Dealer.

2. Rotate left hand gauge wheel or calibration crank to see that feed cups and drive are working properly and are free from foreign matter.

3. Fromthe small seeds seed rate chart on page 35 ﬁnd the setting number for desired feeding rate (and row spacing). Move the small seed cup adjustment lever to that setting number.

4. Record weight of an empty container large enough to hold seed metered for one acre.

5. Place several pounds of seed over three seed cups on an outside end of drill box. Pull seed tubes off of these three openers.

23386

1205NT Calibration Crank

Equations for calibrating seed rate:

measured seed - empty container

= pounds per seed cup

3 (number of seed cups measured)

pounds per seed cup x number of openers = pounds per acre

6. Turn drive gauge wheel or calibration crank several times to ﬁll seed cups with seed. Turn wheel or crank until seed falls to the ground from each cup.

7. Rotate drive gauge wheel or calibration crank 346 rotations. This is equal to one acre.

8. Check that the three seed cups have plenty of seed coming into them.

9. Weighmetered seed. Subtractinitial weight of container. Divide by three. Multiply by the number of openers on your drill to determine total pounds seeded per acre. If this ﬁgure is different than desired, set your seed rate adjustment handle accordingly.

NOTE: You may want to repeat the calibration procedure if your results vary greatly from seed rate chart.

10. When drilling, check seeding rate by noting acres drilled, amount of seed added to small seed box and seed level in small seeds box. If you are seeding more or less than desired, adjust seeding rate slightly to compensate for ﬁeld conditions.

Fertilizer Meter Rate

Fertilizer application rates will vary with fertilizer type, density and particle size. Relative humidity and ﬁeld conditions can also affect application rates. The chart on page 37 is based on material with a density of 65 pounds per cubic foot (1.04 kg/ L) and average particle size. Initially set rate according to the charts, then calibrate the drill to your material as described below.

NOTE: For drills built after October 1, 2005, calibrate using gauge wheels or supplied calibration crank. For drills built before October 1, 2005, cal- ibrate using gauge wheelsor ordercalibration crank kit available through your Great Plains Dealer.

1. To calibrate using gauge wheels, raise drill with tractor hydraulics so drive wheels are off the ground. To calibrate using supplied calibration crank, attach crank to coupler on gauge wheel jackshaft with retaining pin. Disengage lockout on the drive wheels.

2. Rotate drive wheels or calibration crank to see that metering system is working properly and free from foreign material.

1205NT Calibration Crank

Equations for calibrating seed rate:

measured seed - empty container

= pounds per seed cup

3 (number of seed cups measured)

pounds per seed cup x number of openers = pounds per acre

3. From the chart on page 37, ﬁnd the setting number for your row spacing and desired application rate. Rotate gate adjustment knob to the number obtained from the chart.

The fertilizer rate chart is for granular fertilizer with a density of 65 pounds per cubic foot (1.04 kg/L). If you are applying fertilizer with a different density, use the density conversion chart.

4. Check that gauge-wheel tires are the correct size and properly inﬂated. Refer to “Tire Inﬂation Chart”, page 61.

5. Record the weight of an empty container large enough to hold fertilizer metered for one acre.

6. Place several pounds of fertilizer over three fertilizer feed cups on outside end of drill box. Pull fertilizer tubes off these three openers.

7. Turn gauge wheels or calibration crank a few turns to ﬁll feed cups with material. Continue to turn until fertilizer drops to the ground from all three tubes.

8. Place a container under the three tubes to gather metered fertilizer.

9. Turn gauge wheel or calibration crank for approximately 346 rotations (one acre). Check that the three feed cups have plenty of fertilizer coming into them.

10. Weigh metered material. Subtract initial weight of the empty container. Divide by three. Multiply by the number of openers on your drill to determine total pounds-per-acre metered. If this ﬁgure is different than desired, reset adjustment knob accordingly.

NOTE: You may want to repeat the calibration procedure if your results vary greatly from the chart.

Adjustments

1. When drilling, check the rate by noting acres drilled, amount of fertilizer added to the drill and level of material in drill box. If you are applying more or less that desired, adjust the metering rate slightly to compensate for ﬁeld conditions.

Marker Adjustments

Bleeding Marker Hydraulics

The markers must be properly bled to displace air in the hydraulic system and for the sequence valve to work properly. Failure to do so could cause marker to drop quickly and cause damage to marker voiding the warranty.

Overhead and Crushing Hazard:

Keep others away when folding or unfolding markers. Markers may fall quickly and unexpectedly if hydraulics fail.

High Pressure Fluid Hazard:

Check that tractor hydraulic reservoir is full before bleeding the hydraulics. A low reservoir level may draw air back into the system, causing jerky or uneven cylinder movements.

JIC fittings do not require high torque. JIC and O-Ring fittings do not require sealant. Always use liquid pipe sealant when adding or replacing pipe thread fittings. To avoid possible danger of cracking hydraulic fittings from overtightening, do not use plastic sealant tape.

NOTE: Do not try to retract cylinder. The goal is to push air from the lines leading to the cylinder. The position of the sequence valve determines which cylinder will react ﬁrst.

6. When the air is expelled, oil will seep out

around a loosened ﬁtting. Tighten the hose ﬁtting.

7. Move tractor remote lever to fully extend cyl-

inder and hold for a few seconds. This will shift the sequence valve which will allow you to bleed the other cylinder.

Small Seeds Attachment

The small seeds attachment is designed to meter various small seeds. It is driven independently of the main seed box. The small seeds box is 0.24 bushel per foot (27.7 liters/meter) with a total capacity of 2.62 bushes (92.3 liters).

The small seeds attachment is available with two seed release point options: Y-tube release and press wheel release.

With the Y-tube release, seed metered out of the small seeds box is directed into the main seed tube, and drops between the disk blades at the bottom of the opener trench.

With the press wheel release, a separate small seed drop hose is installed on each opener. This releases the seed just ahead of the opener’s depth controlling press wheel.
