SAFE OPERATION

SAFE OPERATION

TRACTOR

Careful operation is your best insurance against an
accident.
Read and understand this manual carefully before
operating the tractor.
All operators, no matter how much experience they may
have, should read this and other related manuals before
operating the tractor or any implement attached to it. It is
the owner's obligation to instruct all operators in safe
operation. 

1. Know your equipment and its limitations. Read this

entire manual before attempting to start and operate
the tractor. 

2. Pay special attention to the danger, warning and

caution labels on the tractor. 

3. Do not operate the tractor or any implement attached

to it while under the influence of alcohol, medication,
controlled substances or while fatigued.

4. Carefully check the vicinity before operating tractor or

any implement attached to it. Do not allow any
bystanders around or near tractor during operation.

5. Before allowing other people to use your tractor,

explain how to operate and have them read this
manual before operation. 

6. Never wear loose, torn, or bulky clothing around

tractor. It may catch on moving parts or controls,
leading to the risk of an accident. Use additional safety
items, e.g. hard hat, safety boots or shoes, eye and
hearing protection, gloves, etc., as appropriate or
required.

7. Do not allow passengers to ride on any part of the

tractor at anytime. The operator must remain in the
tractor seat during operation. 

8. Check brakes, linkage pins and other mechanical

parts for improper adjustment and wear. Replace worn
or damaged parts promptly. Check the tightness of all
nuts and bolts regularly. (For further details, see
"PERIODIC SERVICE OF THE TRACTOR" section.)

9. Keep your tractor clean. Dirt, grease, and trash build

up may contribute to fires and lead to personal injury.

10.Use only implements meeting the specifications listed

under "IMPLEMENT LIMITATIONS" in this manual or
implements approved by KUBOTA. 

11.Use proper weights on the front or rear of the tractor to

reduce the risk of upsets. When using the front loader,
put an implement or ballast on the 3-point hitch to
improve stability. Follow the safe operating
procedures specified in the implement or attachment
manual. 

12. Do not modify the tractor. Unauthorized modification

may affect the function of the tractor, which may result
in personal injury.

C

CAB, ROPS

1. KUBOTA recommends the use of a CAB or Roll Over

Protective Structures (ROPS) and seat belt in almost
all applications. This combination will reduce the risk
of serious injury or death, should the tractor be upset.
Check for overhead clearance which may interfere
with a CAB or ROPS.

2. Set parking brake and stop engine. Remove any

obstruction that may prevent raising or folding of the
ROPS. Do not allow any bystanders. Always perform
function from a stable position at the rear of the tractor.
Hold the top of the ROPS securely when raising or
folding. Make sure all pins are installed and locked.

3. If the CAB or ROPS is loosened or removed for any

reason, make sure that all parts are reinstalled
correctly before operating the tractor.

4. Never modify or repair any structural member of a

CAB or ROPS because welding, bending, drilling,
grinding, or cutting may weaken the structure.

5. A damaged CAB or ROPS structure must be replaced,

not repaired or revised.

6. If any structural member of the CAB or ROPS is

damaged, replace the entire structure at your local
KUBOTA Dealer.

7. If the tractor is equipped with a foldable ROPS it may

be temporarily folded down only when absolutely
necessary for areas with height constraints.
(There is no operator protection provided by the ROPS
in the folded position. For operator safety the ROPS
should be placed in the upright and locked position
and the seat belt fastened for all other operations.)

8. Always use the seat belt if the tractor has a CAB or

ROPS.
Do not use the seat belt if a foldable ROPS is down or
there is no ROPS. Check the seat belt regularly and
replace if frayed or damaged.

1. BEFORE OPERATING THE TRACTOR

SAFE OPERATION

-

2

Operator safety is a priority. Safe operation, specifically
with respect to overturning hazards, entails understanding
the equipment and environmental conditions at the time of
use. Some prohibited uses which can affect overturning
hazards include traveling and turning with implements
and loads carried too high etc. This manual sets forth
some of the obvious risks, but the list is not, and cannot
be, exhaustive. It is the operator's responsibility to be alert
for any equipment or environmental condition that could
compromise safe operation.

C

Starting

1. Always sit in the operator's seat when starting engine

or operating levers or controls. Adjust seat per
instructions in the operating the tractor section. Never
start engine while standing on the ground. 

2. Before starting the engine, make sure that all levers

(including auxiliary control levers) are in their neutral
positions, that the parking brake is engaged, and that
the Power Take-Off (PTO) is disengaged or "OFF".
Fasten the seat belt if the tractor has a CAB, a fixed
ROPS or a foldable ROPS in the upright and locked
position.

3. Do not start engine by shorting across starter

terminals or bypassing the safety start switch.
Machine may start in gear and move if normal starting
circuitry is bypassed. 

4. Do not operate or idle engine in a non-ventilated area.

Carbon monoxide gas is colorless, odorless, and
deadly. 

5. Check before each use that operator presence

controls are functioning correctly. Test safety systems.
(See "Checking Engine Start System" and "Checking
OPC System" in "EVERY 50 HOURS" in "PERIODIC
SERVICE OF THE TRACTOR" section.)
Do not operate unless they are functioning correctly.

C

Working

1. Pull only from the hitch. Never hitch to axle housing or

any other point except hitch; such arrangements will
increase the risk of serious personal injury or death
due to a tractor upset. 

2. Keep all shields and guards in place. Replace any that

are missing or damaged. 

3. Avoid sudden starts. To avoid upsets, slow down

when turning, on uneven ground, and before stopping. 

4. The tractor cannot turn with the differential locked and

attempting to do so could be dangerous.     

5. Do not operate near ditches, holes, embankments, or

other ground surface features which may collapse
under the tractor's weight. The risk of tractor upset is
even higher when the ground is loose or wet. Tall
grass can hide obstacles, walk the area first to be sure.

6. Watch where you are going at all times. Watch for and

avoid obstacles. Be alert at row ends, near trees, and
other obstructions. 

7. When working in groups, always let the others know

what you are going to do before you do it. 

8. Never try to get on or off a moving tractor. 
9. Always sit in the operator's seat when operating levers

or controls. 

10. Do not stand between tractor and implement or trailed

vehicle unless parking brake is applied.

C

Safety for children

Tragedy can occur if the operator is not alert to the
presence of children. Children generally are attracted to
machines and the work they do.
1. Never assume that children will remain where you last

saw them.

2. Keep children out of the work area and under the

watchful eye of another responsible adult.

3. Be alert and shut your machine down if children enter

the work area.

4. Never carry children on your machine. There is no safe

place for them to ride. They may fall off and be run
over or interfere with your control of the machine.

5. Never allow children to operate the machine even

under adult supervision.
