Important Safety Information
These are common practices that may or may not be applicable to the products described in
this manual.
Safety at All Times
Thoroughly read and understand
the instructions given in this
manual before operation. Refer to
the “Safety Label” section, read all
instructions noted on them.
Do not allow anyone to operate
this equipment who has not fully
read and comprehended this
manual and who has not been
properly trained in the safe
operation of the equipment.
The operator must not use drugs
or alcohol as they can change the
alertness or coordination of that
person while operating equipment.
The operator should, if taking over-
the-counter drugs, seek medical
advice on whether he/she can
safely operate the equipment.
Operator should be familiar with all
functions of the tractor and
attachments, and be able to
handle emergencies quickly.
Make sure all guards and shields
are in place and secured before
operating implement.
Keep all bystanders away from
equipment and work area.
Operator must start tractor and
operate controls from the driver’s
seat only. Never from the ground.
Do not leave tractor or implement
unattended with engine running.
Dismounting from a moving tractor
can cause serious injury or death.
Do not allow anyone to stand
between tractor and implement
while backing up to implement.
Keep hands, feet, and clothing
away from power-driven parts.
Watch out for fences, trees, rocks,
wires, etc., while operating and
transporting implement.
Turning tractor too tight may cause
hitched machinery to ride up on
wheels. This could result in injury
or equipment damage.
Look For The Safety Alert 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.
Tractor Shutdown & Storage
If engaged, disengage PTO.
Lower attached implement to
ground, put tractor in park or set
park brake, turn off engine, and
remove switch key to prevent
unauthorized starting.
Wait for all components to come to
a complete stop before leaving the
operator’s seat.
Detach and store implement in an
area where children normally do
not play. Secure implement using
blocks and supports.
OFF
REMOVE
Be Aware of
Signal Words
A Signal word designates a degree or
level of hazard seriousness. The
signal words are:
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.
!
DANGER
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.
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.
!
WARNING
!
CAUTION
For Your Protection
Thoroughly read and understand
the “Safety Label” section, read
all instructions noted on them.

Table of Contents
These are common practices that may or may not be applicable to the products described in
this manual.
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.
Flashing warning lights and turn
signals are recommended
whenever driving on public roads.
Use A Safety Chain
A safety chain will help control
drawn machinery should it
separate from the tractor drawbar.
Use a chain with the strength
rating equal to or greater than the
gross weight of the towed
machinery.
Attach the chain to the tractor
drawbar support or other specified
anchor location. Allow only
enough slack in the chain to
permit turning.
Do not use safety chain for towing.
Maximum transport speed for an
attached implement is 20 mph. DO
NOT EXCEED. Never travel at a
speed which does not allow
adequate control of steering and
stopping. Some rough terrains
require a slower speed.
As a guideline, use the following
maximum speed weight ratios for
an attached implement:
20 mph when weight of attached
implement is less than or equal to
the weight of machine towing the
implement.
10 mph when weight of attached
implement exceeds weight of
machine towing implement but
not more than double the weight.
IMPORTANT: Do not tow a load
that is more than double the weight
of the machine towing the load.
Transport
Machinery Safely
Comply with state and local laws.
Use towing vehicle and trailer of
adequate size and capacity.
Secure equipment towed on a
trailer with tie downs and chains.
Sudden braking can cause a trailer
to swerve and upset. Reduce
speed if trailer is not equipped with
brakes.
Avoid contact with any over head
utility lines or electrically charged
conductors.
Engage parking brake when
stopped on an incline.
Practice Safe Maintenance
Understand procedure before doing
work. Use proper tools and
equipment, refer to Operator’s
Manual for additional information.
Work in a clean dry area.
Lower attached implement to the
ground, put tractor in park, turn off
engine, and remove key before
performing maintenance.
Allow implement to cool before
working on it.
Disconnect battery ground cable (-)
before servicing or adjusting
electrical systems or before welding
on implement.
Do not grease or oil implement
while it is in operation.
Replace parts on this machine with
genuine Great Plains parts only. Do
not alter this machine in a way
which will adversely affect its
performance.
Remove buildup of grease, oil, or
debris.
Remove all tools and unused parts
from implement before operation.

Table of Contents
These are common practices that may or may not be applicable to the products described in
this manual.
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.
Keep Riders Off
Machinery
Never carry riders or use
machinery as a person lift.
Riders obstruct operator’s view.
Riders could be struck by foreign
objects or thrown from the
machine.
Never allow children to operate
equipment.
Avoid High
Pressure Fluids Hazard
Escaping fluid under pressure can
penetrate the skin causing serious
injury.
Avoid the hazard by relieving
pressure before disconnecting
hydraulic lines or performing work
on the system.
Make sure all hydraulic fluid
connections are tight and all
hydraulic hoses and lines are in
good condition before applying
pressure to the system.
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.
DO NOT DELAY. If an accident
occurs, see a doctor familiar with
this type of injury immediately. Any
fluid injected into the skin or eyes
must be treated within
a few hours or
gangrene may
result.
Tire Safety
Tire changing can be dangerous
and should be preformed by
trained personnel using the
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 and 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 the
weight involved.
Use Seat Belt and ROPS
Operate only tractors equipped
with Roll-Over Protective
Structure (ROPS) and seat belt.
Fasten seat belt snugly and
securely to help protect against
serious injury or death from falling
and tractor overturn.
Wearing protective equipment
such as safety shoes, safety
glasses, hard hat, and ear plugs is
highly recommended.
911
Wear
Protective Equipment
Wear protective clothing and
equipment appropriate for the job.
Clothing should be snug fitting
without fringes and pull strings to
avoid entanglement with moving
parts.
Prolonged exposure to loud noise
can cause hearing impairment or
hearing loss. Wear suitable
hearing protection such as
earmuffs or earplugs.
Operating equipment safely
requires the operator’s full
attention. Avoid wearing radio
headphones while operating
machinery.
