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.
▲ Remove all tools and unused
parts from implement before operation.

▲ 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.

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
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.
