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 indicates an imminently hazardous situation
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 indicates a potentially hazardous situation
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 indicates a potentially hazardous situation
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 5,
thoroughly.
Read all instructions noted on the decals.
Keep decals clean. Replace damaged, faded and illegible
decals.

1206NT Table of Contents Important Safety Information 2
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
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 assistance
from a physician familiar with this type of injury.
If an accident occurs, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a
few hours or gangrene can result.
Handle Chemicals Properly
Read and follow chemical manufacturer’s instructions.
Wear protective clothing.
Handle all chemicals with care.
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
Inhaling smoke from any type of chemical fire is a serious
health hazard.
Store or dispose of unused chemicals as specified by the
chemical manufacturer.
Immediately and thoroughly flush any area of the body
that is contaminated by chemicals.
If chemical is swallowed, carefully follow the chemical
manufacturer’s recommendations and consult with a
doctor.
If persons are exposed to a chemical in a way that could
affect their health, consult a doctor immediately with the
chemical label or container in hand. Any delay could
cause serious illness or death.
Dispose of empty chemical containers properly. By law
rinsing of the used chemical container must be repeated
three times. Puncture the container to prevent future use.
An alternative is to jet-rinse or pressure rinse the
container.
After working with chemicals, wash hands and face before
eating. Shower when application is completed for the day.
Never wash out the tanks within 100 feet (30m) of any
freshwater source or in a car wash.
Rinse out the tank. Apply rinse water on last field treated.

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
Transport Machinery Safely
Maximum transport speed for implement is20 mph
(32 km/h). Some rough terrains require a slower speed.
Sudden braking can cause a towed load to swerve and
upset.
Do not exceed 20 mph (32 km/h). Never travel speeds
which do not allow adequate control of steering and
stopping. Reduce speed if towed load is not equipped with
brakes.
Comply with state and local laws.
Do not tow an implement that, when fully loaded, weighs
more than 1.5 times the weight of towing vehicle.
Carry reflectors or flags to mark drill in case of
breakdown on the road.
Keep clear of overhead power lines and other
obstructions when transporting. Refer to transport
dimensions in the Operator’s Manual.

Lower drill, put tractor in park, turn off engine, and
remove the key.
Secure drill using blocks and supports provided.
Detach and store drill in an area where children normally
do not play.Use A Safety Chain
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.
Tire Safety
Tire changing can be dangerous and must 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 for additional
information.
Work in a clean, dry area.
Lower the drill, put tractor in park, turn off engine, and
remove key before performing maintenance.
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 or before welding on drill.

Trucking network. To ease the assembly task and

manual before assembling or setting up new equipment.
Description of Unit
The 1206NT No-Till Drill is a 12' grain drill of end wheel
design which couples Great Plains spring mounted
coulter with a straight arm design of our solid stand
opener to achieve no-till drilling capabilities. The end
wheel design keeps the ground-working components in
line with the end wheels for accurate coulter depth and
seed placement over uneven terrain and allows the unit
to follow field curves without side-loading the openers.
