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.

Great Plains | 401-647M | 2019-06-11 Table of Contents Index 2
3PYPA Table of Contents Index Important Safety Information
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.
Avoid High Pressure Fluids
Escaping fluid under pressure can penetrate the skin,
causing serious injury. This planter requires a
Power-Beyond port, which is always under pressure
when the tractor is running.
Avoid the hazard by relieving pressure at other remotes,
and shutting down tractor before connecting,
disconnecting or inspecting 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.
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
Read and follow chemical manufacturer’s instructions.
Wear protective clothing.
Handle all chemicals with care.
Avoid inhaling smoke from any type of chemical fire.
Store or dispose of unused chemicals as specified by
chemical manufacturer.
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.

Great Plains | 401-647M | 2019-06-11 Table of Contents Index 3
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.
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 is 20 mph
(32 km/h).
Maximum speed in turns is 13 mph (22 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 (32km/h). Never travel at a speed
which does 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 planter in case of
breakdown on the road.
Keep clear of overhead power lines and other
obstructions when transporting. Refer to transport
dimensions under “Specifications and Capacities, 1 of 2”
on page 141.
Do not fold or unfold the planter while the tractor is
moving
Shutdown and Storage
Lower planter, put tractor in park, turn off engine, and
remove the key.
Secure planter using blocks and supports provided.
Detach and store planter in an area where children
normally do not play.

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 planter, 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 planter to cool completely.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on
planter.
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 planter before
operation.
Safety At All Times
Thoroughly read and understand the instructions in this
manual before operation. Read all instructions noted on
the safety decals.
Be familiar with all planter functions.
Operate machinery from the driver’s seat only.
Do not leave planter unattended with tractor engine
running.
Do not stand between the tractor and planter 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 folding and raising
planter. Make sure all persons are clear of working area.

Keep all safety decals clean and legible.
Replace all damaged or missing decals. Order new
decals from your Great Plains dealer. Refer to this
section for proper decal placement.
When ordering new parts or components, also request
corresponding safety decals.
