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.

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

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

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.

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.

Operating Instructions
This section covers general operation. Experience,
machine familiarity, and the following information will lead
to efficient operation and good working habits. Always
operate farm machinery with safety in mind.
Prestart Checklist
1. Carefully read “Important Safety Information,” be-
ginning on page 1.
2. Lubricate implement as indicated under Lubrication,
“Maintenance and Lubrication,” page 42.
3. Check all tires for proper inflation as indicated on Tire
Inflation Chart,“Appendix,” page 53.
4. Check all bolts, pins and fasteners. Torque as speci-
fied on Torque Values Chart,“Appendix,” page 53.
5. Check implement for worn or damaged parts. Repair
or replace before going to the field.
6. Check hydraulic hoses, fittings and cylinders for leaks.
Repair or replace before going to the field.
Field Operation
1. Hitch implement to a suitable tractor. Refer to Hitching
Tractor to Implement,“Preparation and Setup,” page
13.
2. Set seeding rate. Refer to “Checking the Seeding
Rate,” page 36.
3. Load box with clean seed.
4. Lower the drill and hydraulically adjust coulters to de-
sired depth. Note reference measurement on tonguecylinder gauge to help you achieve the same coulter
depth with each field pass. Refer to Coulter Depth,
“Adjustments,” page 27, for further adjustment instructions.
5. Retract transport cylinders until opener bodies are
level with the ground when the coulters are at the desired depth. Cylinder depth rings are provided to hold
the openers to the desired setting. Set opener depth
and begin seeding. Refer to Opener Depth,“Adjust-
ments,” page 30.
6. Always lift drill out of ground when turning at row ends
and for other sharp turns. Seeding will stop automatically as drill is raised and contact drive wheels lose
contact with drive tires.

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.

Follow the chart at the right as a guide. Actual fan speeds
will vary with seeding rates, seed weights and seed size.
Increase fan speed for heavier seeding rates or seed.
Reduce fan speed for lighter seeding rates and seed more
prone to cracking.
Marker Operation
Optional markers are on their own hydraulic circuit. They
operate through a sequence valve which alternates lower
and lift cycles between the right hand and left hand
marker.
