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 25 kph. Some rough terrains
require a slower speed. Sudden
braking can cause a towed load to
swerve and upset.
▲ Do not exceed 25 kph. 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 tow-
ing.
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.

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 2000 is a pull-type seeding implement. The
implementhas 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.
The drill is equiped with hydraulic brakes which work in
conjuction with the tractor brakes. There is a seperate
park brake lever which locks the brake when appllied.

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 7.5 liters (2
gallons).
If drill is folded:
1. Makesure theopener foldlock pins arein place. Loosen the fittings at the rod endof 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. Makesure theopener foldlock pins arein place. Loosen the fittings at the base end of each coulter fold cylinder and at the rod end of each opener foldcylinder.
Supplyoil as tofoldthe drill. As oilbegins to seepfrom
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.

2. Withtractor idling, activatetractor hydraulicvalveuntil
oilseeps out around a loosenedfitting. Tighten that fitting.
IMPORTANT: JIC fittings do not require high torque. JIC
and O-ring fittingsdo 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
threetimes to completely purge airfrom 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
Tofold properly, the marker hydraulics must be freeof 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.
Markersmayfall quickly and unexpectedlyif the hydraulics fail.
Neverallow anyonenear the drill when folding or unfolding the
markers.
Check that tractor hydraulic reservoir is full. Marker hydraulic capacity is 5.8 liters (1 1/2 gallons).

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 25 kph (20 mph).
• 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 sufficient tractor. Refer to Hitching Tractor to Implement,
“Preparation and Setup,” Page 9. Makesure safety
chain is secured to tractor.
2. Unload seed box before transporting if atall 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 49.
4. Know implement dimensions in transport position.
Choose a route that provides adequate clearance
from all obstructions. Refer to “Specifications and
Capacities,” page 43, for dimensions.
5. Plug light-harness lead into tractor connector. Always
use warning lights when transporting drill.
6. Release parking brake.
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
downpressure by addingtractor weights toframe. Refer to Added Weight, page 25.
• 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
aheadof eachopener onthe drill.The coulterscut 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 23, for informationon these
adjustments.
The amount of coulter down pressure needed to cut a soil
groove varies with soil conditions. Adding weight orshortening the coulter spring increases coulter down pressure
and cutting force. Refer to Coulter Down Pressure, page
25, 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 canbe changed. Refer
to Opener Depth, page 26, for information on these
adjustments.
The amount of opener down pressure needed to cut and
widen the coulter grooveand tofirm the seed into the soil
varies with soil conditions. Openerdown pressurecan be
adjusted for all openers or individual openers. Refer to
Opener Down Pressure, page 27, for information on how
to make these adjustments.

Coulter Depth
Adjust coulters to run 13mm to 25mm (1/2” to 1”) 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. Retracttonguecylinder totransferthetractor weightto
the coulter toolbar.

Refer to Figure 23
2. Lowerthe 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 levelwith the ground when
the coulters and openers are at the desired depth.
