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. The signal words are:

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.

Keep Riders Off Machinery

Riders obstruct the operator’s view. Riders could be struck by foreign objects or thrown from machine.

▲ Never allow riders on implement. ▲ Never allow children to operate

equipment.

For Your Protection

▲ Thoroughly read and understand

Safety Decals, page 4. Read all instructions noted on decals.

OFF

Shutdown and Storage

▲ Lower machine to ground, put

tractor in park, turn off engine, and remove key.

▲ Detach and store implement in an

area where children normally do not play. Secure implement with blocks and supports.

Handle Chemicals Properly

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

▲ Wear protective clothing. ▲ Handle all chemicals with care. ▲ Follow instructions on container

label.

▲ Avoid inhaling smoke from any

type of chemical ﬁre.

▲ Store or dispose of unused chem-

icals as speciﬁed by chemical manufacturer.

Use Safety Lights and Devices

Slow-moving tractors, self-propelled equipment 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 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 that does not

allow adequate control of steering and stopping.

▲ Comply with state and local laws. ▲ Reduce speed if towed load is not

equipped with brakes.

▲ Do not tow an implement that,

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

Use A Safety Chain

▲ Use a safety chain to help con-

trol drawn machinery should it separate from tractor drawbar.

▲ Use a chain with a strength rat-

ing equal to or greater than 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.

Practice Safe Maintenance

▲ Understand procedure before

doing work. Use proper tools and equipment. Refer to this manual for additional information.

▲ Work in a clean, dry area. ▲ Lower implement to ground, put

tractor in park, turn off engine, and remove key before performing maintenance.

▲ Allow implement to cool completely. ▲ Inspect all parts. Make sure parts

are in good condition and installed properly.

▲ Remove buildup of grease, oil or

debris.

▲ Remove all tools and unused

parts from implement before operation.

Prepare for Emergencies

▲ Be prepared if a ﬁre starts. ▲ Keep a ﬁrst-aid kit and ﬁre extin-

guisher handy.

▲ Keep emergency numbers for

doctor, ambulance, hospital and ﬁre department near phone.

911

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 radio headphones while operating machinery.

Avoid High Pressure Fluids Hazard

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

▲ Avoid the hazard by relieving

pressure before disconnecting hydraulic lines.

▲ Use a piece of paper or card-

board, not body parts, to check for suspected leaks.

▲ Wear protective gloves and safety

glasses or goggles when working with hydraulic systems.

▲ If an accident occurs, see a doc-

tor immediately. Any ﬂuid injected into the skin must be surgically removed within a few hours or gangrene may result.

Safety at All Times

Thoroughly read and understand this manual before operation. Refer to Safety Decals, page 4. Read all instructions noted on decals.

▲ Be familiar with all implement

functions.

▲ Operate implement from driver’s

seat only.

▲ Do not leave tractor or implement

unattended with engine running.

▲ Do not dismount a moving tractor.

Dismounting a moving tractor could cause serious injury or death.

▲ Do not stand between tractor and

implement during hitching.

▲ Keep hands, feet and clothing

away from power-driven parts.

▲ Wear snug-ﬁtting clothing to avoid

entanglement with moving parts.

▲ Watch out for wires, trees, etc.,

when raising implement. Make sure all persons are clear of working area.

▲ Do not turn tractor too tight, caus-

ing implement to ride up on wheels. This could result in injury or equipment damage.

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

▲ When removing and installing

wheels, use wheel-handling equipment adequate for weight involved.

Introduction

Great Plains Mfg., Inc.

Great Plains welcomes you to its growing family of new product owners. This implement 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 NTA 2000D is a pull-type seeding implement. The implement has No-till coulters and openers intricately connected on a center pivot. No-till coulters mounted on the front frame zone-till strips for seed furrows. Straight-arm openers on the rear frame prepare seedbeds and place the seed. The pivoting action of the frames allows drill openers to track the coulters. A contact-drive tire powers the seed meter from a transport tire. The tongue cylinder and transport tires control the coulter and opener depth. Transport cylinders raise the drill for turns and transport.

Intended Usage

Use this implement for seeding production-agriculture crops only. Do not modify implement for use with attachments other than those specified by Great Plains. Use implement in no till or minimum tillage.

Bleeding Hydraulic Systems

WARNING!

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. Foreign ﬂuids in the tissue must be surgically removed within a few hours or gangrene will result.

Note: For safe and smooth operation, the hydraulic systems must be free of air. The hydraulic systems should be bled during initial implement set-up. If they were not bled, or if you replace a hydraulic component during the life of the drill, bleed the hydraulics.

Bleeding Lift Hydraulics

1. Check hydraulic ﬂuid level in tractorreservoir and ﬁll to proper level. Add ﬂuid to system as needed while cycling new cylinders. LIft hydraulic capacity is 2 gallons (7.5 liters).

2. Lower drill to ground.

3. Loosen the ﬁttings at the base end of each transport lift cylinder. Supply oil to the base ends of the cylinders until oil seeps from loosened ﬁttings. Tighten those ﬁttings.

4. Supply oil to the base ends and completely extend the cylinders. Insert transport lock channels.

5. Loosen the ﬁttings at the rod end of each transport lift cylinder. Supply oil to the rod ends of the cylinders until oil seeps from loosened ﬁttings. Tighten those ﬁttings.

6. Remove transport lock channels and cycle drill up and down three times.

Bleeding Tongue Cylinder

1. Check hydraulic ﬂuid in tractor reservoir and ﬁll to proper level. Add ﬂuid to system as needed. Tongue cylinder capacity is 1/2 gallon (1.9 litres).

2. Raise and safely support hitch, transport frame and front tongue.

3. Unpin rod end of tongue cylinder. Block, wire or other-

wise safely support cylinder so when rod end is fully extended it does not contact anything.

4. Cycle cylinder completely in and out at least three times to purge air from cylinder and hoses.

5. Fully extend cylinder and repin rod end.

6. Recheck tractor reservoir and ﬁll to proper level.

CAUTION!

You may be injured or killed by a folding or unfolding opener or coulter frame.

Bleeding Fold Hydraulics

Check hydraulic fluid level in tractor reservoir and fill to proper level. Add fluid to system as needed while cycling new cylinders. Fold hydraulic capacity is 2 gallons (7.5 liters).

If drill is folded:

1. Make sure the opener fold lock pins are in place. Loosen the ﬁttings at the rod end of each coulter fold cylinder and at the base end of each opener fold cylinder. Supply oil as to unfold the drill. As oil begins to seep from the loosened ﬁttings, tighten those ﬁttings. Do not unfold the wing sections at this time.

2. Make sure the opener fold lock pins are in place. Loosen the ﬁttings at the base end of each coulter fold cylinder and at the rod end of each opener fold cylinder. Supply oil as to fold the drill. As oil begins to seep from the loosened ﬁttings, tighten those ﬁttings. Continue supplying oil as to completely fold the drill for at least ﬁve seconds.

3. Remove the fold lock pins and unfold the drill.

CAUTION!

Use extreme caution because some sudden dropping of the wings may occur if a small amount of air still remained in the cylinders.

4. Fold and unfold the drill three more times.

9/13/2006

NTA 2000D 148-632M

Page 18

If drill is unfolded:

1. Make sure the wing sections are on the ground. Loosen the ﬁttings at the base end of each coulter fold cylinder and at the rod end of each opener fold cylinder. Supply oil as to fold the drill. As oil begins to seep from the loosened ﬁttings, tighten those ﬁttings. Do not fold the wing sections yet.

2. Make sure the wing sections are still on the ground. Loosen the ﬁttings at the rod end of each coulter fold cylinder and at the base end of each opener fold cylinder. Supply oil as to unfold the drill. As oil begins to seep from the loosened ﬁttings, tighten those ﬁttings. Continue supplying oil as to completely unfold the drill for at least ﬁve seconds.

3. Fold the drill.

CAUTION!

Use extreme caution because some sudden dropping of the wings may occur if a small amount of air still remained in the cylinders.

Great Plains Mfg., Inc.

2. With tractor idling, activate tractor hydraulic valve until oil seeps out around a loosened ﬁtting. Tighten that ﬁtting.

IMPORTANT: 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 cracking hydraulic fittings from over tightening, do not use plastic sealant tape.

3. Reactivate tractor hydraulic valve until oil seeps out around another loosened ﬁtting. Tighten that ﬁtting. Repeat process until all loosened ﬁttings have been bled and tightened.

4. Cycle both cylinders completely in and out at least three times to completely purge air from cylinders and hoses.

5. Repin cylinders and cycle markers at least three times.

4. Fold and unfold the drill three more times.

Bleeding Marker Hydraulics

To fold properly, the marker hydraulics must be free of air. If the markers fold in jerky, uneven motion, follow these steps.

CAUTION!

You may be injured if hit by a folding or unfolding marker. Markers may fallquickly and unexpectedly if the hydraulics fail. Never allow anyone near the drill when folding or unfolding the markers.

Check that tractor hydraulic reservoir is full. Marker hydraulic capacity is 1 1/2 gallons (5.8 liters).

1. With both markers lowered into ﬁeld position, unpin rod end of each cylinder andblock cylinder up so it can be extended and retracted safely and without contacting anything. Loosen hydraulic-hose ﬁttings at rod and base ends of marker cylinders. Loosen ﬁttings on back side of sequence valve.

IMPORTANT: Never bleed an O-ring fitting. Instead, bleed a nearby pipe or JIC fitting.

Opener Operation

Never back up with openers in ground. If you do, check all openers to be sure none are clogged or damaged.

For information on seeding depth and opener adjustments, refer to Seeding Depth,“Adjustments,” page 26. For more information on troubleshooting opener problems, see “Troubleshooting,” page 39.

Fan Operation

Refer to Figure 4

The selector valve diverts the folding circuit to the fan circuit.

The fan must be operated with the return oil line connected to a low back pressure sump return on the tractor. Check with tractor manufacturer for proper connection of oil sump return line. A low back pressure quick disconnect is supplied with the drill for ease of connection to the tractor sump return line.

Use tractor remote hydraulic valve flow control to set fan speed.

Run fan for at least 15 minutes before seeding. Hydraulic fluid must be warm before fan will operate properly.

Watch monitor and adjust fan speed by increasing or decreasing hydraulic flow from tractor.

Use the fan speed chart as a guide. Actual fan speeds will vary with seeding rates, seed weights and seed size. Increase fan speed for heavier seeding rate or seed. Reduce fan speed for lighter seeding rates and seed more prone to cracking.

Set the fan speed for the type of seed and seed rate being planted. Refer to “Seed Rate Charts,” page 48. Operating the fan at higher than recommended speeds can cause seeds to be blown out of the opener seed trench.

Note: Do not operate fan above 4500 RPM.

Transporting

WARNING!

Towing the implement at high speeds or with a vehicle that is not heavy enough can lead to loss of vehicle control. Loss of vehicle control can lead to serious road accidents, injury and death. To reduce the hazard:

• Do not exceed 20 mph (25kph).

• Do not tow an implement that, when fully loaded, weighs

more than 1.5 times the weight of the towing vehicle.

1. Check that implement is securely hitched to a sufﬁ-

cient tractor. Refer to Hitching Tractor to Implement, “Preparation and Setup,” Page 13. Make sure safety chain is secured to tractor.

2. Unload seed box before transporting if at all possible.

The implement can be transported with a full box of grain, but added weight will increase stopping distance and decrease maneuverability.

3. Check that tires are properly inﬂated. Refer to Tire In-

ﬂation Chart,“Appendix,” page 53.

4. Know implement dimensions in transport position.

Choose a route that provides adequate clearance from all obstructions. Refer to “Speciﬁcations and Capacities,” page 47, for dimensions.

5. Plug light-harness lead into tractor connector. Always

use warning lights when transporting drill.

Comply with all laws when travelling on public roads.

Adjustments

Seeding Depth

To set drill seeding depth, you must:

• Set coulter depth with tongue cylinder and gauge wheels.

• Set opener depth with T-handles on press wheel.

• If field conditions make it necessary, increase coulter

down pressure by adding tractor weights to frame. Refer to Added Weight, page 29.

• If necessary, adjust individual coulters or openers to seed in tire tracks.

The following is an introduction to how the coulters and double-disk openers are designed to control seeding depth.

Coulters

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

Coulter cutting depth is controlled by the tongue cylinder and the gauge wheels. You also can change the depth of individual coulters by changing coulter-mounting height. Refer to Coulter Depth, page 27, for information on these adjustments.

The amount of coulter down pressure needed to cut a soil groove varies with soil conditions. Adding weight or shortening the coulter spring increases coulter down pressure and cutting force. Refer to Coulter Down Pressure, page 29, for more information on these adjustments.

Openers

Opener double disks travel in the coulter path to make a seed bed. Mounted on the rear of each opener is a press wheel. The press wheels control opener seeding depth and firms the seed into the soil.

To maintain a consistent seeding depth, upward press wheel movement is restricted by an independently adjustable stop on each opener. Moving this stop changes the depth at which seed is placed. The mounting height of openers that run in tire tracks also can be changed. Refer to Opener Depth, page 30, for information on these adjustments.

The amount of opener down pressure needed to cut and widen the coulter groove and to firm the seed into the soil varies with soil conditions. Opener down pressure can be adjusted for all openers or individual openers. Refer to Opener Down Pressure, page 31, for information on how to make these adjustments.

Great Plains Mfg., Inc.

NTA 2000D 148-632M 9/13/2006

Coulter Depth

Adjust coulters to run 1/2” to 1” (13 to 25 mm) below the drill openers. Coulter depth can be adjusted hydraulically for all coulters or manually for individual coulters.

Hydraulic Control

Make the following adjustment when drilling in level ground with the seed box half full.

1. Retract tongue cylinder to transfer the tractor weight to the coulter toolbar.

17218

Refer to Figure 23

2. Lower the drill and set tongue cylinder so coulters are at desired depth. Note the setting on cylinder gauge so you can return to the same depth.

NOTE: Use cylinder gauge only as a reference. Gauge does not measure actual coulter depth.

Refer to Figure 24

3. Adjust the cylinder spacers on the transport cylinders so the opener bodies are level with the ground when the coulters and openers are at the desired depth.

Figure 23

Cylinder Gauge

Coulter Wing Adjustment

Set the coulter wing frames so the wing coulters run at exactly the same depth as the center frame coulters. This is accomplished with two adjustments.

Refer to Figure 26

1. Add or remove spacer shims from behind coulter frame stop studs. The studs should allow the coulters to drop slightly below the desired operating depth to allow the coulter lock pins to be installed and removed easily.

Great Plains Mfg., Inc.

Refer to Figure 27

2. Adjust the lock link trunnion nuts so the wing coulters run exactly the same depth as the center frame coulters. The coulters must be lowered into the ground so soil pressure is forcing the wings upward to make sure the lock link trunnions are properly set.

Coulter Mounting Height

You can change the depth of individual coulters by adjusting coulter-mounting height. If you adjust coulter height, be sure to rebolt coulters vertically straight and correctly spaced. To raise or lower individual coulters:

1. Loosen mounting clamps and adjust coulterto desired height. Do not lower coulter spring bar below top Ubolts on coulter clamp.

Refer to Figure 28

2. To re-tighten clamps. Snug hex-head clamp bolts (1) just until U-bolts are tight on each side of spring bar.

3. Tighten nuts (2) on U-bolts.

4. Finish tightening hex-head clamp bolts (1).

NOTE: Even when coulter is held securely, there may be a gap between clamp halves.

Coulter Down Pressure

Added Weight

Refer to Figure 29

In hard soil conditions where coulter penetration is limited, you can add suitcase weights to brackets on the hitch frame. The weight brackets are locatedon each side of the drill fan. Adding weight on the hitch frame provides the best weight distribution for no-till drilling.You can add up to 2000lbs (907kg) of additional weight. Place an equal amount of weight on each weight bracket.

Coulter Springs

Refer to Figure 30

Coulter-spring length is preset at the factory to10” (254 mm), giving coulters an initial operating force of 400 pounds (181 kg). This setting is adequate for many difficult no-till conditions. For lighter no-till conditions where rocks or other obstructions are a problem, you can reduce coulter down pressure to give coulters better impact protection. Refer to the following chart for adjusting coulter down pressure.

Opener Down Pressure

Refer to Figure 33

To adjust down pressure on individual openers that run in tire tracks, change opener-spring length.

1. To increase down pressure, loosen the jam nut at the lower end of opener spring, then turn ﬂange nut. Each additional 1/4” (6 mm) of spring compression adds about 13 pounds (6 kg) of pressure. After adjusting ﬂange nut, tighten jam nut.

IMPORTANT: Do not compress spring more than one inch (25 mm). Compressing spring more than one inch (25 mm) could cause opener damage and void the warranty.

Disk Scraper Adjustment

Refer to Figure 34

To keep opener disks turning freely, dirt scrapers are mounted between disks to clean as the disks rotate. As field conditions vary, you may need to adjust the scrapers.

2. To adjust, loosen 3/8” bolt and raise or lower scraper as needed.

Leaf Spring Adjustment

Refer to Figure 35

A leaf spring is located just ahead of the vertical pivot. The spring is designed to provide just enough force to keep the opener frame square and stable for turning at field ends and to add stability for drilling in rough field conditions. Proper leaf-spring adjustment is important for smooth implement operation.

1. To adjust properly, square the opener frame to the coulter frame and adjust 3/8” U-bolts (1) on each side until leaf-spring rollers (2) just make contact with roller pads (3) on opener frame. When the U-bolts are adjusted properly the opener frame should be square with the coulter frame when the drill is raised.

Harrow Adjustments

Refer to Figure 36

The illustration shows a successful harrow position for notill conditions. Because of different soil moisture, trash levels and trash types, you may need to reposition the tube frame or tines. Initially position the frame and tines as shown, then readjust as necessary.

1. To adjust the frames, loosen the hex nuts (1) on the U-bolts and rotate the frame tube (2) as necessary. Tighten nuts.

Refer to Figure 37

2. To adjust the tines, loosen the 1/2” hex nuts (3) on the 1/2” U-bolts that attach the tine tubes to the harrow frames.

3. Rotate tine tubes (4) so the tines are against the stop bushings and are angled back as necessary. Retighten hex nuts on U-bolts.

CAUTION!

Before working around the drill make sure it is properly hitched to the tractor and that the tractor is turned off and the transmission is in the park position. Make sure the drill is on level ground and the coulter and opener wing frames are in their unfolded position. For proper hitching and unfolding instructions refer to the operators manual for this drill.

Figure 36

Frame Adjustment

Great Plains Mfg., Inc.

19887

Refer to Figure 38

Note: The light bar brackets on the drill must be adjusted so the lights are just behind the wing opener press wheels and just ahead of the wing harrow when the drill is folded. Use extreme caution when folding the drill for the first time after the harrows are installed. Slide the light bar brackets forward or backward as necessary so the wing opener press wheels and wing harrows do not contact the lights.

4. To adjust the transport height of the center harrow section, raise the drill and install the transport lock channels on the transport cylinders and the tongue cylinder.

5. Remove the 7/16” lock nuts (1) and 7/16” x 2 3/4” bolts (2) from the center pull arms and the chain links on chain (3).

6. The center section must rest low enough in the transport position to allow the wing sections to fold over the top of the center section without contacting it. This position is slightly lower than the maximum down position of the wing sections.

7. Select a chain link to adjust the transport height of the center section. Carefully fold the drill to make sure the wing harrow sections do not contact the center section. Make adjustments as necessary to get the maximum center section transport height without wing section contact.

8. Make sure both chains are adjusted to the same length so the section raises and lowers evenly.

Marker Adjustments

Folding Speed

Refer to Figure 39

1. Adjust folding speed with hex adjustment screws on the sequence-valve body. There is one adjustment screw for raising speed (1) and one for lowering speed (2). Identify adjustment screws by markings stamped in valve body.

2. With tractor idling at a normal operating speed, adjust marker folding to a safe speed.Turn adjustment screws clockwise to decrease folding speed and counterclockwise to increase folding speed. Excessive folding speed could damage markers and void the warranty.

3. After adjusting the folding speed, tighten jam nuts on hex adjustment screws to hold settings.

Disk Adjustments

Refer to Figure 40

If mark left by marker disk is not easy to see, change disk angle to make a wider mark.

1. Loosen two 1/2” carriage bolts (1) holding disk mount. Rotate disk mount as desired.

If the marker disk is not square with the ground when the marker is lowered in the field, or if marker arm tends to fold up while lowered in the field, change disk angle relative to ground.

2. Loosen 1/2” bolts (2) and rotate marker mount until marker disk is square with ground.

3. To adjust where the disk marks, loosen U-bolt (3) and slide marker-mount tube in or out as necessary. Retighten U-bolt.

Cylinder Lock Channel

Refer to Figure 41

The markers should be in transport position when opening a field or when drilling next to obstructions.

14048

Figure 39

Speed Adjustment, Sequence Valve

Figure 40

Disk Angle

Refer to Figure 42

1. For ﬁeld operation the cylinder lock channels must be placed on the cylinder rods so only the outer two sections of the markers fold. This speeds up marker cycle time and reduces wear on markers.

2. The markers have breakaway protection to keep them from being damaged if the marker strikes a solid object. The breakaway bolt should only be replaced with a 3/8-16 x 2” Gr 5 bolt (Great Plains P/N 802-143C) and two 3/8” nuts (Great Plains P/N 803-014C). It is important to use two nuts on the breakawaybolt. Extra bolts and nuts can be purchased and stored in the extra holes of the breakaway plate.

Feed Flaps

Spring loaded flaps, one below each roller allows the seeding of a wide range of seed sizes and are used to positively control the flow of small seeds to large seeds through the feed rollers without causing bruising or crushing. They also act as a safety devise for the feed rollers. The spring loaded flap “gives” to allow a stone or other obstructions through without damaging the rollers.

Refer to Figure 46

1. The ﬂaps under all the rollers are adjusted by a single lever at the right hand end of the hopper. A series of notches in the guide bracket set the lever to the required ﬂap opening. Position 1 is the upper setting at which the ﬂaps are closest to the feed roller.

Refer to Figure 47

Note: Each ﬂap should just touch the feed roller at position

1. This is factory set, however, if adjustment is required,

tighten or slacken the lock screw below the required ﬂap to keep all ﬂaps equal across the meter.

The recommended position for the Feed Flap lever setting for different seed types is as follows:

• Position 1: Small seeds e.g. rape, when the flap is closest to the feed roller.

• Position 2: Cereals e.g. wheat and barley.

• Position 3: Large seeds e.g. peas and beans.

Note: Refer to the seed rate charts for proper feed ﬂap setting.

Half Width Shut-Off

Refer to Figure 48

Half width shut-off provides for:

a. Seeding of a narrow width when ﬁnishing a ﬁeld to

prevent double seeding.

b. To start a ﬁeld in the correct sequence when tram-

lining.

To disengage, insert tool into clutch grooves and rotate the clutch until the two drive roll pins are in line. Slide clutch to the left until the right drive roll pin is disengaged. Rotate clutch one quarter turn back to lock it onto the left drive roll pin to prevent the clutch from reengaging.

Note: The left- hand side of the feed mechanism is disengaged. Re-engage by rotating the clutch from it’s lock position and allow it to slide back to the right.

NOTE: CHECK TO BE SURE THE CLUTCH HAS FULLY RE-ENGAGED.

Checking the Seeding Rate

The following procedure should be followed to calibrate the drill for different seed types. Note that the following factors may affect seeding accuracy:

• Errors in land area which are affected by wheel slip, operator judgement and by inaccurate knowledge of field size.

• Errors in metering which are affected by seed treatments, seed size, variety, moisture content and seed bulk density.

To calibrate the drill, an accurate set of scales will be required. Other equipment is supplied with the drill and includes calibration trays and handle.

Procedure

Refer to Figure 49

1. Release the two black plastic lock screws above each venturi unit by loosening, sliding the knob up and retightening.

2. Push the left and right venturi units forward to clear the feed units.

Refer to Figure 50

3. Remove calibration tray (a) from storage position above the feed rollers by loosening center knob (b) and sliding lock tab down.

Refer to Figure 51

4. Position the calibration trays under the feed rollers.

5. Refer to the “Seed Rate Charts,” page 48, for the seed to be sown. Set to the “High” or “Low” speed, adjust the ﬂaps below the feed rollers to the required position and adjust the variator lever to the setting indicated on the guide chart to give the target rate.

6. Ensure that the drill is not in a tramlining bout so that all the feed rollers turn when the seed shaft is rotating.

7. Fill the hopper with at least 110 lbs. (50 kg) of seed to ensure that all the feed rollers are covered throughout the test.

Refer to Figure 52

8. Position the crank handle on the input point of the Variator and rotate clockwise to “prime” the feed mechanism. It is important to turn the handle at least 50 turns before calibrating to ensure seed is ﬂowing correctly through the system. Empty the calibration trays before carrying out a full test.

9. Rotate the crank handle 41 turns. (For extra accuracy it is recommended to carry out a Calibrations for Num- ber of Turns, described on the next page).

10. Weigh the seed collected from both trays in pounds. Use an accurate set of scales. This amount is equivalent to 1/10th acre.

Seeding Rate (lb/ac)=Weight Collected (lb) x 10

11. If the result is different to the required rate, adjust the Variator to increase or decrease the seeding rate. Remember to re-prime the feed mechanism with at least 50 turns before re-calibrating.

Note: Always move the Variator handle down to zero then back up to the required setting.

Calibrations for Number of Turns

As indicated at the start of this section, accuracy in calibration can be affected by a number of factors not least of which is soil type, wheel slip and sinkage. The number of turns recommended for the calibration crank handle are based on “average” figures in normal field conditions. If farm conditions are very stony (so little sinkage) or very sandy (so greater sinkage) then using the recommended number of crank handle turns may be inaccurate.

To check the number of turns for individual field conditions:

Refer to Figure 53

1. Shut down the shut-off slide above each roller to prevent seeding.

2. Fill the drill half to two-thirds full of seed.

3. Mark out 218 feet of seedbed.

4. Position the calibration handle on the Variator input and rotate to the upright (12 o’clock) position to give a clear starting point.

5. Drive the distance marked-off in the seedbed and count the number of turns the calibration handle makes.

6. Note the number of turns and use this ﬁgure in the Checking the Seeding Rate procedure in the previous section in place of the standard.

Hopper Clean-out

Refer to Figure 54

The seed hopper has two slide gates connected to discharge hoses for cleaning out the bulk of the seed from the hopper. Each slide gate is controlled by a handle that extends out beyond the end of the meter assembly. The discharge hose can be directed into a bag or into the auger hopper.

Final meter clean-cut must be done using the calibration trays. Slide the venturi units forward and place the calibration trays under the feed rolls. Move the flap adjustment handle to the full open position and empty the remaining seed into the trays. The flap handle can be closed when the trays are emptied.

Refer to Figure 55

The air distribution chamber must be inspected and keep clean daily.

1. Remove end caps and visually inspect chamber.

2. To clean chamber, remove end caps and blow out chamber with the fan.

Make sure the area around the openings is clear and that no one will enter the area before starting fan.

Tramlining

The meter can automatically leave tractor track marks or “tramlines” in the correct position for subsequent accurate bout matching of spraying and fertilizing applications.

The system operates by stopping the drive to2+2feed rollers (two in the left side of the hopper for the left track mark and two in the right side of the hopper for the right track mark) as factory fitted, these will give a tramline track width of 3 times the drill row spacing.

Refer to Figure 56

Drive to the two feed rollers at the left end of each half of the meter assembly is disengaged by arms attached to an electric actuator. These feed rollers are marked with tractor tread decals on the back of the meter assembly.

Drive is automatically engaged/disengaged in the required sequence by the monitor control box positioned in the cab. A magnet and sensor on the contact drive record the bout count. See separate monitor instruction section for further information and programming instruction.

Setting up for Tramlines

The drill is set up to do “symmetrical tramlining” for 60 ft. applicator booms, or “asymmetrical right tramlining” for 40 ft. and 80 ft. applicator booms. See Tramlining instructions in the Monitor section of this manual. With the optional NTA2000 dual tramline controls kit, (Great Plains P/N 890-785C) the drill can be set up for 10 bout tramlining for 50 ft. applicator booms or 18 bout tramlining for 90 ft. applicator booms.

Any seed hose can be connected to the tramline marked feed rolls on the air distribution chamber. For symmetrical tramlining, connect the right tramline marked feed rolls to the desired two rows right of center to leave a mark for the right sprayer track, and connect the left tramline marked feed rolls to the desired two rows left of center to leave a mark for the left sprayer track

Asymmetrical Right Tramlining

Asymmetrical right tramlining only requires the use of the right tramline marked feed rolls. The actuator arm to the left tramline marked feed rolls must be disconnected.

For asymmetrical right tramlining connect the right tramline marked feed rolls to the desired two rows at the right end of the drill to leave a mark for the sprayer tracks on two consecutive passes.

Refer to Figure 57

Disconnect the actuator arm at the left side of the meter assembly that operates the left feed roll tramline clutch. This arm will have to be tied over to the right so the “star shaped” teeth on the arm do not slide over and contact the feed roll clutch spring.

Note: With the optional NTA2000 dual tramline controls kit, (Great Plains P/N 890-785C) it will not be necessary to disconnect the actuator arm.

Multi-function Drill Control

Monitor

The multi-function drill monitor controls the operation and tramlining functi on of pneumatic type seed drills. The instrument has an illuminated 4 digit display with 6 display functions and alarm functions for forward

speed, fan rpm and seed distribution shaft rpm. The speed and area functions can be displayed in either metric or imperial units.

The instrument indicates:

• Forward Speed (plus low speed alarm)

• Part Area and Total Area worked

• The current bout number and tramline bouts for the selected tramlining sequence.

• Fan rpm (plus low/high speed alarm)

• Seed Distribution Shaft rpm (plus low speed alarm)

• Hopper level low

The tramlining function is the priority display. The instrument will default to this channel display 10 sec onds after selecting another display function (with the exception of displa ying an area t otal or when the drill is out of work).

It has two memory registers (Total 1 and Total 2) to record area worked. The area is accumulated to both memory registers. Area totals and all calibration data are automatically stored in memory when the instrument is powered off.

The instrument must be initially calibrated to suit the implement being co ntrolled. Three program mod es allow the default settings to be altered as required. Most of these settings do not need to be accessed in normal use.

Speed Sensor Calibration

The forward speed sensor is magnetically operated and senses the land wheel rotation. In order to display the correct spee d and accumulate area correctly, the instrument must be programmed with the correct Speed Sensor Factor (SSF). This is the distance traveled between two signal pulses received from the sensor.

The S.S.F. can be calculated theoreticall y and then manuall y programmed, or the instrument can automatically calculate it via the “Autocal” function.

If this action is forgotten, the alarm will be triggered and the instrument will default to the shaft speed channel

The display will now be ignored and the area accumulation reduced by 50%. The instrument will revert back to normal operation when either a shaft speed signal is

received (i.e. the seed shaft has been mechanically re-engaged for full width oper ation), or the instrument is unplugged and plugged back in again.

Disabling the Distribution Shaft Alarm

Alternatively, you can turn off the alarm by pressing and holding the button for 5 seconds with the shaft speed channel selected. The display will then show ‘OFF’ when this channel is selected. The alarm function will sta y off until the instrument is unplugged and plugged back in again.

Alarm Delay Time

Some crops – notably oilseed rape (canola) are drilled at very low rates so the seed shaft runs extremely slow and the instrument may sense that the shaft has actually stopped, thus triggering the shaft speed alarm. The programmable delay time can prevent the alarm being triggered need lessly in such a situation.

When drilling at higher rates, a long time dela y is equally undesirable. In this case a shorter time delay can be programmed.

Default delay time = 40 seconds Minimum delay time = 5 seconds

Hose Connection and Routing

1. Assemble the seed hoses from the seed box to the openers. Route each hose from the center of the box to the end opener. Follow the same manner of routing until the end, in which the hose from the outside opening of the seed box will be routed to the center opener. Use the hose brackets in routing the hoses from the seed box to the openers to keep hose up off the drill.

Note: Using the charts on the right, select the proper row spacing for your drill to determine the correct hose to use in each position.

Note: When allof themeter outlets are not used (i.e: 7 1/2”) it is best to leave the outside meters open.
