Introduction
The Great Plains 3P1006NT drill is a two-point
mounted no-till drill with lift-assist wheels for
operation and transport.
The standard 3P1006NT model has a main seed
box. A second seed box (dual seed), fertilizer, native
grass, and/or small seed capability may be added.
Intended Use Statement
The 3P1006NT drill with standard equipment and/or
authorized attachments and options is intended to be
used as a seeding implement when operated
according to instructions and safety precautions in
this manual, machine decals, or other information
provided with the machine.
Use this drill to seed grasses or production-
agriculture crops, or to seed over existing grass
stands. Use on terrain that is flat to semi-flat or gently
rolling.
Any other use, for example, using the machine as a
grader or cultivator tool, is not permitted. The
manufacturer and dealers are not liable for damage
caused by improper use.
The straight arm, double-disk openers disks make a
seed bed. Seed tubes mounted between the disks
place seed in the furrow. Press wheels following the
opener disks close the furrow and gauge the opener
seeding depth.
The seed metering system is driven from one or both
front gauge wheels. Seeding rates are set by a
gearbox, rate adjustment handles, and/or sprocket
selection.
Right-hand and left-hand side are determined by
facing the direction of forward travel.
Prohibited Use

Great Plains | 151-144U | 2019/03/14 3
Safety Information
The safety symbol indicates a potential safety
hazard to persons operating or near the
machine and advises on how to avoid it.
The notice symbol indicates a potential for
machine or property damage from operator
error and advises on how to avoid misuse.
The information symbol indicates useful - but
not crucial - information for machine
operation, assembly, or adjustment.
Before Getting Started
1. Read this manual in its entirety before attempting
to start and operate the machine.
2. Only use operators that are thoroughly trained by
the owner or trained by someone with the
owner’s consent. The operator must be familiar
with all functions of the tractor and attachments,
and be able to handle emergencies quickly.
3. Maintain attention on operation at all times. Do
not operate if using a smart phone, tablet, or
similar electronic device, and never operate
machine while impaired by alcohol, medication,
any controlled substance, or while fatigued.
4. Do not ever allow passengers to ride the machine
at any time, for any reason.
5. Before operation, make sure that all tractor cab
levers are in their neutral positions and that the
parking brake is engaged.
6. Check brakes, link pins, and other mechanical
parts for wear before using machine.
7. Never wear loose or bulky clothing around
machine. Use additional safety equipment, such
as hard hats, eye and ear protection, safety
boots, etc., as needed.
8. Do not modify the machine. Unauthorized
modification can result in unsafe conditions that
lead to machine damage or personal injury.
Operation
1. Always stop the tractor, put in Park and turn off
engine before leaving the cab. Dismounting from
a moving tractor can cause serious injury or
death.
2. Consider turning radius of tractor and implement
in the field. Turning tractor too tight can cause
hitched implement to ride up on wheels which
can result in injury or equipment damage.
3. Pull machine only from the hitch at the end of the
tongue. Never pull from jack stand, safety chain,
or any point other than the hitch.
4. Never leave the tractor cab unattended while the
implement is running. Remove key and turn off
tractor before exiting the tractor cab.
5. Watch your surroundings at all times. Do not
operate with bystanders nearby, and avoid
contacting overhead obstructions.
6. Check that all guards and shields are
undamaged, installed, and secure before
operating implement.
7. Keep children out of the work area. Do not
operate or turn on machine while children are in
the area.
8. Do not operate near ditches, holes, steep slopes,
embankments, or other surfaces which may
collapse under the machine’s weight or tip the
machine over.
9. Never stand between tractor and implement
unless parking brake is applied.

Handling and Disposing of Chemicals
Agricultural chemicals can be dangerous. Improper
use can seriously injure persons, animals, plants, soil
and property.
1. Read chemical manufacturer’s instructions
carefully, and then take appropriate precautions
before use.
2. Wear protective clothing.
3. Wash hands and face before eating after working
with chemicals. Shower as soon as application is
completed for the day.
4. Apply only with acceptable wind conditions.
Make sure wind drift of chemicals will not affect
any surrounding land, people or animals.
5. Dispose of unused chemicals and chemical
waste as specified by the manufacturer. Observe
all the local ordinances and regulations in your
area.
Operation Noise Hazard
1. Use proper ear protection like headphones or
earplugs while working.
PTO
1. Wait until all moving components have
completely stopped before adjusting, cleaning, or
servicing any PTO driven equipment.
2. Before installing or using PTO driven equipment,
read the tractor manual and review the safety
labels attached to the equipment.
3. When operating stationary PTO driven
equipment, always apply the parking brake and
place chocks behind wheels.
4. Stay clear of and never step over any rotating
parts.
Maintenance
1. Understand procedure before doing work. Use
proper tools and equipment.
2. Work in a clean, dry area.
3. Lower the implement. Put tractor in Park, turn off
engine. To prevent unauthorized starting, remove
key before performing maintenance or service
work.
4. If work must be performed with wings raised, set
the wing tilt locks to the road position.
5. Make sure all moving parts have stopped and all
system pressure is relieved.
6. Relieve hydraulic pressure before disconnecting
hydraulic lines or performing any work on the

is necessary, secure implement with stands or
suitable blocking beforehand.
8. Disconnect electronic monitor and lighting
harness from the tractor before servicing or
adjusting electrical systems.
9. Before welding, disconnect electronic monitor

High Pressure Fluids
1. Escaping fluid from holes in hydraulic lines is
difficult to spot. Do not use your hands or bare
skin to search for suspected leaks; instead, use a
piece of cardboard or wood. If injured by
escaping hydraulic fluid, see a medical
professional immediately. Exposure can result in
gangrene or severe allergic reaction.
2. Check that hydraulic fittings are tight and all
hydraulic hoses and lines are in good condition
before applying pressure to the system.
3. Wear protective gloves and safety glasses or
goggles when working with hydraulic systems.
Transporting
1. As with transporting any piece of heavy
machinery, comply with all local laws and
regulations before and during transport process.
2. Transport only at recommended transport speed
for implement. Some rough terrains require a
slower speed. Sudden braking can cause a
towed load to swerve and upset.
3. Before towing implement on roads, make sure to
empty out all material from the hoppers or boxes.
4. Know transport height and width of implement.
5. Do not tow an implement that, when fully loaded,
weighs more than 1.5 times the weight of towing
vehicle.
6. Keep clear of overhead power lines and other
obstructions when transporting.
7. Do not fold or unfold the implement while the
tractor is moving.
8. Reduce speed when turning, and make as wide
a turn as possible. Turning tractor too tight can
cause implement to tip over.
9. When towing on a trailer, secure implement with
tie downs and chains.
10. When towing on a trailer, sudden braking can
cause a trailer to swerve and upset. Reduce
speed if trailer is not equipped with brakes.
Safety Chain
1. Use a chain with a strength rating equal to or
greater than the gross weight of towed
machinery.
2. Replace chain if any links or end fittings are
broken, stretched or damaged.
3. Do not use safety chain for towing.
Safety Lights and Devices
1. Always use safety lighting. Slow-moving tractors
and towed machinery can create a hazard when
driven on public roads. They are difficult to see,
especially at night.
2. If equipped, use flashing warning lights and turn
signals whenever driving on public roads.
3. Use safety devices provided with implement.
4. Keep safety lights and signs clean and visible
from front and rear of machine.
5. Keep lights in operating condition.
Shutdown and Storage
1. Park the tractor and implement on a solid, level
surface where children normally do not play.
2. Fold and tilt wings.
3. Put tractor in park or set the parking brake. Turn
off engine and remove switch key to prevent
unauthorized starting.
4. Wait for all components to come to a complete
stop before leaving the operator’s seat.
5. Turn lockout valve and wing lock levers to locked
position to prevent the wings from lowering.
6. Detach the tractor. Secure the implement using
blocks.
Proper Waste Disposal
1. Dispose of waste properly to avoid threatening
the environment and ecology. Potential harmful
waste includes oil, fuel, filters, and batteries.
2. Use a leak-proof container for draining fluids. Do
not use a food or beverage container that may be
mistaken for a consumable product.
3. Do not drain or pour waste onto the ground,
down a drain, or into any water source.
4. Contact your local environmental or recycling
center for the proper way to recycle or dispose of
waste.

3P1006NT Table of Contents Index Preparation and Setup
Great Plains | 151-144U | 2019/03/14 11
Preparation and Setup
This section helps you prepare your tractor and drill
for use.
Preparation Checklist
Read and understand “Safety Information”
starting on page 3.
Check that all working parts are moving freely,
bolts are tight, and cotter pins are spread.
Check that all grease fittings are in place and
lubricated. See “Lubrication” on page 31.
Connect any seed or fertilizer hoses
disconnected for storage.
Check that all safety decals and reflectors are
correctly located and legible. Replace if
damaged. See “Safety Decals” starting on
page 6.
Inflate tires to pressure recommended and
tighten wheel bolts as specified. See “Tire and
Wheel Information” on page 53.
Serious Machine Damage Risk
Make sure that caster locks are not
engaged when operating machine in the
field. Serious damage can be done to the
machine if attempting to steer side-to-side
with caster locks engaged.
Hitching Drill to Tractor
Crushing Hazard
You may be severely injured or killed by
being crushed between the tractor and
drill. Do not stand or place any part of your
body between drill and moving tractor. Stop
tractor engine and set park brake before
installing hitch pins.
This drill is a semi-mounted 3-point category II hitch
implement.
Hitch Extension
Falling Object Hazard
There is no top link on the drill to prevent the
extension hitch from tipping forward with
risk of serious injury, or backward causing
machine damage.
Never mount an extension hitch by itself on
the drill.
If no hitch extension is required, skip to step 1.
On tractors with oversize tires, or unusual wheel
bases, the rear tractor tires may be too close to, or
touch drill components when directly hitched. A hitch
extension kit is available (page 56).
The extension hitch is compatible with most standard
quick hitches.
Equipment Damage Risk
Great Plains CPH, PFH or SSH accessory
hitches are not compatible with the
3P1006NT.
Mount the extension hitch on the tractor before
hitching to the drill.
1. Use a lift or hoist to bring the extension hitch
upright and lift it high enough to engage with the
lower arms of the tractor 3-point.
2. Align the top link (1) with the tractor top link arm,
and secure with a pin provided with the extension
hitch. The lift or hoist may be removed.
3. Adjust the tractor top link as needed, and swing
the extension until the lower links (2) are aligned
with the tractor’s lower arms. Secure with pins
provided with the extension hitch.
The rear top link (3) is unused. It provides a
lifting point. Use a lower hitch pin from the
drill as needed.

3P1006NT Table of Contents Index Preparation and Setup
Semi-Mounted Hitching
If a hitch extension is required, mount it on the tractor
before hitching the drill.
1. Raise or lower tractor 3-point arms, or hitch
extension, as needed and pin lower arms to drill.
Upper arm is unused.
2. Set your tractor 3-point draft control to float
position.
Equipment Damage Risk
Do not raise 3-point until after hydraulic and
electrical connections have been made.
Hydraulic Hose Hookup
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. Use paper or
cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. If
injured, seek immediate medical attention
from a physician familiar with this type of
injury.
Connect hydraulic system to tractor before lifting the
drill.
The hydraulic system of the drill has one dual-acting
lift-assist cylinder.The cylinder raises the rear of the
drill during lift (tractor 3-point lift arms raise the front).
There is a counterbalance valve in the system to
prevent sudden drops due to leaks or hose rupture.
1. Determine which tractor remote to use for lift
assist, and set the lever for that circuit to float (to
relieve any pressure).
2. Connect the lift hose to the extend port of the
tractor remote. Connect the return hose to the
retract port.
If lift is uneven, when the hydraulic system is first
charged, and if air is allowed in the system, bleed the
system. See “Bleed Hydraulics” starting on
page 30.
Great Plains hydraulic hoses are color coded to help
you hookup hoses to your tractor outlets. Hoses that
go to the same remote valve are marked with the
same color.
Electrical Connection
1. Make sure tractor is shut down with accessory
power off before making connections.
2. Connect lighting connector and any options or
after-market electronics to tractor outlets.
3. Tie up excess cable, allowing enough slack for
the drill to tilt back.
Make Electrical Connections
Make connections prior to machine
movement.
(1) #1 Yellow - LH Flashing Lights
(2) #6 Red - Brake Lights
(3) #5 Empty
(4) #4 Green - RH Flashing Lights
(5) #3 White - Ground
(6) #2 Blue - Aux Power
(7) #7 Brown - Tail Lights
Leveling the Drill
Crushing Hazard
To avoid serious injury, do not raise drill
higher than necessary to adjust wheels.
Level the drill in field conditions. If done on hard
ground or pavement, coulters and openers may
prevent correct drill level.
1. Make sure the caster locks are not engaged. See
“Caster Locks” on page 17.
2. Extend the lift-assist cylinders. See “Drill Raise
and Lower” on page 16.
3. Initially adjust the tractor 3-point lift arms so the
opener tube runs at the recommended initial
height of 62.9 cm (A) above the ground when the
drill is lowered in the field.

4. The drive wheel should be in the fourth mounting
hole (1) from the top. This is the factory
configuration.
The drive wheel axle height may need to be
adjusted due to ground conditions.
5. Check the level of the frame front-to-rear. If not
level, adjust the rear height with the stroke control
spacers.
Stroke Control Spacers
The height of the drill at the rear, when lowered, is
adjusted with a set of stroke control spacers (1). Five
snap-around spacers are stored on the storage rod
for a combined length of 165 mm.
If planting in rolling terrain, it may be necessary to
adjust the lift assist cylinder manually with the tractor
hydraulics to allow the machine to float backwards.
1. Remove the desired combination of stroke
control spacers from the storage rod (2) and
install on the cylinder rod (3). There is no factory
recommendation for this, as it depends on the
tractor used.
2. Lower the drill until the cylinders rest on the
stroke control spacers.
3. Pull the drill forward to put coulters and openers
in the ground. Make sure that lift-assist casters
are in trailing position. Set the tractor brakes.
4. When the correct level has been achieved, set a
stop, lock, or reference indicator on the tractor’s
hitch control to prevent lowering below drill level.
5. Check the level of the frame front-to-rear. If not
level, adjust the rear height with the stroke control
spacers. If changed, re-check the front tool bar
height, and re-adjust the tractor 3-point lift arms.
Repeat until level.

Distance from Center of Gravity
Observe the total weight, axle loads, tire load-bearing
capacity and minimum ballast specifications.
The front or rear attachment of machines must not
cause the tractor’s permissible total weight, its
permissible axle load, or its tire load-bearing capacity
to be exceeded. In order for steering capability to be
maintained, the front axle must bear at least 20% of
the tractor’s unladen weight.
By investing some effort in making the calculations,
you can determine the:
total weight
axle load
tire load-bearing capacity
minimum ballast
For this calculation, the following data is required:
Data from the tractor’s operator manual:
(A) Unladen weight in kg.
(B) Front axle load in kg.
(C) Rear axle load in kg.
Take into consideration any further weights, such as
water in the tires, additional equipment, etc.
Data from this operator manual:
(D) Total weight of the machine in the rear
attachment. For hitched machines, the
supporting load in kg.
(E) Total weight of the machine in the front
attachment in kg.
(F) Distance between the machine’s center of
gravity in the front attachment and front axle
midpoint in m.
(G) Distance between the lower link ball midpoint
and the machine’s center of gravity in the rear
attachment in m. With hitched machine:
Maximum empty (main seed box, dual seed or
native grass, and small seeds) - G=1.48 m.
Minimum empty (main seed box only) -
G=1.47 m.
Data to be measured:
(H) Tractor’s wheel base in m.
(I) Distance between the rear axle midpoint and
the lower link ball midpoint in m.
