Important Safety Information
Look for Safety Symbol
The SAFETY ALERT SYMBOL indicates there is a
potential hazard to personal safety involved and extra
safety precaution must be taken. When you see this
symbol, be alert and carefully read the message that
follows it. In addition to design and configuration of
equipment, hazard control and accident prevention are
dependent upon the awareness, concern, prudence and
proper training of personnel involved in the operation,
transport, maintenance and storage of equipment.
Be Aware of Signal Words
Signal words designate a degree or level of hazard
seriousness.
DANGER, and the color Safety Red, indicate an
imminent hazard which, if not avoided, will result in death
or serious injury. This signal word is limited to the most
extreme situations, typically for machine components
that, for functional purposes, cannot be guarded.
WARNING, and the color Safety Orange, indicate a
potential hazard which, if not avoided, could result in
death or serious injury, and includes hazards that are
exposed when guards are removed. It may also be used
to alert against unsafe practices.
CAUTION, and the color Safety Yellow, indicate a
potential hazard which, if not avoided, may result in
minor or moderate injury. It may also be used to alert
against unsafe practices.
Prepare for Emergencies
Be prepared if a fire starts
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctor, ambulance, hospital
and fire department near phone.
Be Familiar with Safety Decals
Read and understand “Safety Decals” on page 6,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

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 entertainment headphones while
operating machinery.
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
Do not use liquid seed treatments with the 3P606NT or
606NT.
Read and follow chemical manufacturer’s instructions.
Wear protective clothing.
Handle all chemicals with care.
Avoid inhaling smoke from any type of chemical fire.
Never drain, rinse or wash dispensers within 100 feet
(30 m) of a freshwater source, nor at a car wash.
Store or dispose of unused chemicals as specified by
chemical manufacturer.
Dispose of empty chemical containers properly. Laws
generally require power rinsing or rinsing three times,
followed by perforation of the container to prevent re-use.
Avoid High Pressure Fluids
(Model 605NT or 606NT only)
Escaping fluid under pressure can penetrate the skin,
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic lines.
Use a piece of paper or cardboard, 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, seek immediate medical attention
from a physician familiar with this type of injury.

2018-06-06 Table of Contents Index 151-061M
Use an Adequate Tractor
Model 3P605NT or 3P606NT only:
Ensure that the tractor is rated for, and correctly ballasted
for the drill’s 3-point loading. Check that drill plus ballast
does not exceed the tractor’s capability.
Avoid transport with material loaded in boxes.
Model 605NT or 606NT only:
Ensure that the tractor weighs at least 2/3(67%) of the
drill (including the weight of any Options and materials).
Avoid transport with material loaded in boxes.
Use A Safety Chain
(Model 605NT or 606NT only)
Use a safety chain to help control drawn machinery
should it separate from tractor drawbar.
Use a chain with a strength rating equal to or greater than
the 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.
Keep Riders Off Machinery
Riders obstruct the operator’s view. Riders could be
struck by foreign objects or thrown from the machine.
Never allow children to operate equipment.
Keep all bystanders away from machine during operation.
Use Safety Lights and Devices
Slow-moving tractors 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

3P605NT, 3P606NT, 605NT & 606NT Table of Contents Index Important Safety Information 4
Transport Machinery Safely
Maximum transport speed for the implement on its own
tires is 20 mph (30 kph). Rough terrain may require a
slower speed. Sudden braking can cause a towed load to
swerve and upset.
Do not exceed 20 mph (30 kph). Travel only at a speed
which allows adequate control of steering and stopping.
Comply with state and local laws.
Carry reflectors or flags to mark drill in case of
breakdown on the road.
3-point implements reduce weight on steering tires. Verify
that tractor is correctly ballasted. Watch for signs of poor
steering traction.
Shutdown and Storage
Park on level ground.
Unhitch and store the drill in an area where children
normally do not play.
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 for you to stand to one side–not in front
of or over tire assembly. Use a safety cage if available.
When removing and installing wheels, use wheel-handling
equipment adequate for weight involved.
Practice Safe Maintenance
Understand procedure before doing work. Use proper
tools and equipment. Refer to this manual.
Work in a clean, dry area.
Lower the drill, put tractor in park, turn off engine, and
remove key before performing maintenance. If work must
be performed with implement raised, use blocks or
jackstands rated for the drill weight.
Make sure all moving parts have stopped and all system
pressure is relieved.
Allow drill to cool completely.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems.
Welding: Disconnect battery ground. Avoid fumes from
heated paint.

Introduction
Great Plains welcomes you to its growing family of new
product owners. Your 6-Foot No-Till Drill 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 605NT and 606NT are towed seeding implements.
This drill has a working width of 7.5 feet (1.9 m). The drill
has straight arm, double disc 05 or 06 Series openers.
The opener discs make a seed bed, and seed tubes
mounted between the discs place seed in the furrow.
Press wheels following the opener discs close the furrow
and gauge opener seeding depth. A T-handle on the
opener body makes seeding depth adjustments.
The metering system is driven from the gauge wheel
(3-point), or from the left end wheel (pull-type). Seeding
rates are set by rate adjustment handles and a Drive
Type gearbox for the main seed box.
Intended Usage
Use this implement to seed production-agriculture crops
in conventional or minimum tillage applications.
Models Covered
This manual applies to Great Plains drill models:
Standard 3P605NT, 3P606NT, 605NT or 606NT Models
have a main seed box. Native Grass and/or Small Seeds
capability may be added.

Hydraulic Hose Hookup (605NT or 606NT)
High Pressure Fluid Hazard:
Shut down tractor before making hydraulic connections. Only
trained personnel should work with system hydraulics.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Use paper or
cardboard, NOT BODY PARTS, to check for leaks. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. If an accident occurs, seek immediate
medical assistance from a physician familiar with this type of
injury.
Refer to Figure 7
Hydraulic hoses have directional handles and are color
coded to help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve pair are marked
with the same color.
To distinguish hoses on the same hydraulic circuit, refer
to the symbols on the handles. Hose under
extended-cylinder symbol feeds cylinder base ends.
Hose under retracted-cylinder symbol feeds cylinder rod
ends.
Electrical Connections
Refer to Figure 8
5. Plug drill electrical lead into tractor seven-pin
connector. If your tractor is not equipped with a
seven-pin connector, contact your dealer for
installation.
