Important Safety Information
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 32 kph (15 mph). Some
rough terrains require a slower
speed. Sudden braking can cause a
towed load to swerve and upset.
▲ Do not exceed 25 kph (15 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.

Introduction
Introduction
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 1000 and NTA 1300 is a pull-type seeding implement. The implement is mounted on a center-pivot hitch.
The hitch and drill are integrally connected. No-till coulters
are mounted on the hitch to zone-till strips for seed furrows. Straight-arm openers on the drill prepare seedbeds
and place the seed. The pivoting action of the hitch helps
drill openers track the coulters. A contact-drive tire on the
drill powers seeding from a hitch tire. The tongue cylinder
and transport tires control the coulter depth and 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.

Hydraulic Hook-up
!
WARNING!
Escaping fluid under pressure can have sufficient force to penetrate the skin. Check all hydraulic lines and hoses before applying pressure. Fluid escaping from a very small hole can be
almost invisible. Use paper or cardboard, not body parts, to
check for suspected leaks. If injured, seek medical assistance
from a doctor that is familiar with this kind of injury. Foreign
fluids in the tissue must be surgically removed within a few
hours or gangrene will result.
Great Plains hydraulic hoses are colour coded to help
you hook-up hoses to your tractor outlets. Hoses that go
to the same remote valve are marked with the same colour.

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
The lift system is equipped with rephasing hydraulic cylinders that require a special procedure for bleeding air from
the system. Read and follow the procedure carefully.
1. Check hydraulic fluid level in tractor reservoir and fill to
proper level. Add fluid to system as needed while cycling new cylinders. LIft hydraulic capacity is 23 liters
(6.1 gallons).
2. Lower drill to ground.
3. Unpin rod ends of wheel cylinders. Pivot cylinders up
and wire or otherwise safely support rod ends higher
than base ends. You may need to remove the transport wheel cylinders from the mainframe so you can
orient them with rod ends higher than base ends.
Bleeding Tongue Cylinder
8. Check hydraulic fluid in tractor reservoir and fill to
proper level. Add fluid to system as needed. Tongue
cylinder capacity is 1.89 litres (one-half gallon).
9. Raise and safely support hitch, transport frame and
front tongue.
10. Unpin rod end of tongue cylinder. Block, wire or otherwise safely support cylinder so when rod end is fully
extended it does not contact anything.
11. Cycle cylinder completely in and out at least three
times to purge air from cylinder and hoses.
12. Fully extend cylinder and repin rod end.
13. Recheck tractor reservoir and fill to proper level.
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 5.6 liters (1.5 gallons). If drill fold cylinders have not been extended:
1. Crack fittings at base end of cylinders. Extend cylinders to purge air from system.
2. Crack fittings at rod end of cylinders. Retract cylinders
to purge remaining air from system.
3. Tighten all fittings. Extend cylinders and pin to drill
lugs.
If drill cylinders have been extended:
1. Unfold drill so that fold cylinders are completely extended. Lower drill to ground. Unpin rod ends of fold
cylinders.
2. Crack fittings on rod end of cylinders. Purge air from
cylinders by retracting cylinder rods.
3. Crack fittings at base end of cylinders. Extend cylinders to purge remaining air from system.
4. Tighten all fittings. Repin cylinders to drill.
4. With the tractor engine at idle speed, energize the lift
hydraulics. When the cylinders have extended completely, hold the remote lever on for one minute. Check
all hydraulic hoses, cylinders and fittings for leaks.
5. Retract the cylinder rods. Extend the rods again and
hold the remote lever on for one more minute. Repeat
this step two more times.
6. Again, check all hydraulic hoses, cylinders and fittings
for leaks. Recheck the tractor hydraulic reservoir. Fill
to the proper level.
7. Repin all cylinders.

CAUTION!
You may be injured if hit by a folding or unfolding marker.
Markers may fallquickly andunexpectedly ifthe 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 1.2 liters (.32 gallons).
1. With both markers lowered into field position, loosen
hydraulic-hose fittings at rod and base ends of marker
cylinders. If applicable, loosen fittings on back side of
sequence valve.
IMPORTANT: Never bleed an O-ring fitting. Instead,
bleed a nearby pipe or JIC fitting.
2. With tractor idling, activate tractor hydraulic valve until
oil seeps out around a loosened fitting. Tighten that fitting.
Preparation and Set-Up
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.

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 20.
For more information on troubleshooting opener problems, see “Troubleshooting,” page 27.
Pivot Lock Tubes
Refer to Figure 8
The pivot-lock tubes are behind the stabilizer cylinders on
each side of implement.
Refer to Figure 9
During normal fieldoperation, operate hitch with pivot-lock
tubes unsecured so hitch can pivot and drill openers can
properly track coulters.
Refer to Figure 10
When drilling on steep slopes or while transporting,
secure pivot-lock tubes. To lock tubes, turn tubes so they
are horizontal with hitch frame.
You can adjust spring tension on pivot-lock tubes. Refer to
Pivot Lock Tube Adjustment, “Adjustments,” page 26.
Marker Operation
Optional markers are on their own hydraulic circut. They
operate through a sequence valve which alternates lower
and lift cycles between the right hand and left hand
marker.
Fan Operation
Refer to Figure 11
The selector valve diverts the fan circuit to the fold cylinders. This pertains to the NTA 1300 only.
Transport Lift Cylinders
The transport-lift cylinders are rephasing hydraulic cylinders. After a period of normal use, the cylinders may get
out of sequence. If this happens, the hitch will lift unevenly
or one set of tires will not retract from the soil.
To rephase cylinders, raise drill completely and hold
hydraulic lever on for a few seconds to allow cylinders time
to rephase.

Adjustments
Seeding Depth
To set drill seeding depth, you must:
• Set coulter depth with tongue cylinder and guage
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.
• 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 hitch 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 guage wheels. You also can change the depth of
individual coulters by changing coulter-mounting height.
Refer to Coulter Depth, page 21, 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
21, 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 22, 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 23, for information on how
to make these adjustments.
Adjustments
NTA 1000 and NTA 1300 148-528M 5/26/2006

Page 23
Great Plains Mfg., Inc.
Coulter Depth
Adjust coulters to run 13 to 25 mm (1/2 to 1 inches) 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.
Refer to Figure 21
2. Set tongue cylinder so coulters are at desired depth.
Note 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 22
3. With coulters and drill lowered to desired seeding
depth, check that hitch frame runs parallel with
ground.
Refer to Figure 23
4. If the hitch frame is not level, remove or replace spacers from transport-lift-cylinder rods until hitch is level.

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 clampsand adjustcoulter todesired
height. Do not lower coulter spring bar below top ubolts on coulter clamp.
Refer to Figure 24
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 25
In hard soil conditions where coulter penetration is limited,
you can add suitcase weights to brackets on the hitch
frame. Adding weight on the hitch frame provides the best
weight distribution for no-till drilling.You can add up to
450kg (1000 lbs, on a 3 meter drill) or 590kg (1300lbs, on
a 4 meter drill) of additional weight. Place an equal amount
of weight on each weight bracket.
Coulter Springs
Refer to Figure 26
Coulter-spring length is preset at the factory to 254 mm
(10 inches), giving coulters an initial operating force of 181
kg (400 pounds). 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 tothe followingchart for adjusting coulter
down pressure.

Opener Down Pressure
Refer to Figure 29
To adjust down pressure on individual openers that run in
tire tracks, change opener-spring length. To increase
down pressure, loosen the jam nut at lower end of opener
spring, then turn flange nut. Each additional 6 mm (1/4inch) of spring compression adds about 6 kg (13 pounds)
of pressure. After adjusting flange nut, tighten jam nut.
IMPORTANT: Do not compress spring more than 25
mm (one inch). Compressing spring more than 25 mm
(one inch) could cause opener damage.
Disk Scraper Adjustment
Refer to Figure 30
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.
To adjust, loosen 3/8-inch bolt and raise or lower scraper
as needed.

Harrow Adjustment
Refer to Figure 31
The illistration shows a successful harrow position for
no-till 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.
Refer to Figure 31
1. To adjust the frame, loosen the eight hex nuts (1)
on the u-bolts and rotate the frame tube (2) as
necessary.
Refer to Figure 32
2. To adjust the tines, loosen the 1/2-inch hex nuts
(3) on the 1/2-inch u-bolts that attach the tine
tubes to the harrow frames . Rotate tine tubes (4)
so the tines are against the stop bushings andare
angled back as necessary. Re-tighten hex nuts
on u-bolts.
Leaf Spring Adjustment
Refer to Figure 33
A leaf spring is located just ahead of the vertical pivot.
The spring is designed to provide just enough force to
keep the hitch 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.
To adjust properly, square tongue with transport
frame and adjust 3/8-inch u-bolts (1) on each side
until leaf-spring rollers (2) just make contactwith roller
pads (3) on transport frame. Make sure both right and
left sides are adjusted equally.

adjustment screws by markings stamped in valve body.
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.
After adjusting the folding speed, tighten jam nuts on hex
adjustment screws to hold settings.
Disk Adjustments
Refer to Figure 35
If mark left by marker disk is not easy to see, change disk
angle to make a wider mark. Loosen two 1/2-inch 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. Loosen 1/2-inch bolts (2) and rotate marker
mount until marker disk is square with ground.
To adjust where the disk marks, loosen u-bolt (3) and slide
marker-mount tube in or out as necessary. Re-tighten ubolt.

falling implement. Always have transport locks in place and
frame sufficiently blocked up when working on implement.
Maintenance and Lubrication
!
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.
1. After using implement for several hours, check all
bolts to be sure they are tight.
2. Inflate tires as specified on Tire Inflation Chart,“Ap-
pendix,” page 37.
3. Replace any worn, damaged or illegible safety decals.
Obtain new decals from your Great Plains dealer. Refer to Safety Decals,“Important Safety Information,”
