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.

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 attention
from a physician familiar with this type of injury.
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.
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 when
folding/unfolding, raising/lowering markers,
raising/lowering openers, and transporting.
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 and cart.
Check for Overhead Lines
Seed auger or implement markers contacting overhead
electrical lines can introduce lethal voltage levels on
implement, cart and tractor frames. A person touching
almost any metal part can complete the circuit to ground,
resulting in serious injury or death. At higher voltages,
electrocution can occur without direct contact.
Avoid overhead lines during seed loading/unloading and
marker operations.

2020-08-05 Table of Contents Index 160-037M
Transport Machinery Safely
Maximum transport speed for implement is 20 mph
(32 kph). Some rough terrains require a slower speed.
Sudden braking can cause a towed load to swerve and
upset.
Do not exceed 20 mph (32 kph). 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 national, regional and local laws.
Follow your tractor manual recommendations for
maximum hitch loads. Insufficient weight on tractor
steering wheels will result in loss of control.
Carry reflectors or flags to mark implement and cart 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” on
page 58.
Handle Chemicals Properly
Agricultural chemicals can be dangerous. Improper use
can seriously injure persons, animals, plants, soil and
property.
Do not use liquid treatments with implement.
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.
Shutdown and Storage
Clean out and safely store or dispose of residual
chemicals.
Secure implement using blocks and transport locks. Lower
openers if not locked up.
Store 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.
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.
Disconnect battery ground cable (-) before servicing or
adjusting electrical systems or before welding on
implement.
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.
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.
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 cart and implement functions.
Operate machinery from the driver’s seat only.
Do not leave implement unattended with tractor engine
running.
Do not dismount a moving tractor. Dismounting a moving
tractor could cause serious injury or death.
Do not stand between the 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.

Safety Decals
Safety Reflectors and Decals
Your implement comes equipped with all lights, safety
reflectors and decals in place. They were designed to
help you safely operate your implement.
Read and follow decal directions.
Keep lights in operating condition.
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.
To install new decals:
1. Clean the area on which the decal is to be placed.
2. Peel backing from decal. Press firmly on surface,
being careful not to cause air bubbles under decal.

raised/lowered or are in the raised position.
Keep others away.
