SAFE OPERATION
-1SAFE OPERATION
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. BEFORE OPERATING THE TRACTOR
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. Before allowing other people to use your tractor,
explain how to operate and have them read this
manual before operation.
5. 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.
6. Do not allow passengers to ride on any part of the
tractor at anytime. The operator must remain in the
tractor seat during operation.
7. Check brakes, clutch, 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 "MAINTENANCE" section.)
8. Keep your tractor clean. Dirt, grease, and trash build
up may contribute to fires and lead to personal injury.
9. Use only implements meeting the specifications listed
under "IMPLEMENT LIMITATIONS" in this manual or
implements approved by KUBOTA.
10.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.
11. The narrower the tread, the greater the risk of a tractor
upset. For maximum stability, adjust the wheels to the
widest practical tread width for your application. (See
"TIRES, WHEELS AND BALLAST" section.)
(1) Rear wheels (A) Tread Width
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. If the CAB or ROPS is loosened or removed for any
reason, make sure that all parts are reinstalled
correctly before operating the tractor.
3. Never modify or repair any structural member of a
CAB or ROPS because welding, bending, drilling,
grinding, or cutting may weaken the structure.
4. A damaged CAB or ROPS structure must be replaced,
not repaired or revised.
5. If any structural member of the CAB or ROPS is
damaged, replace the entire structure at your local
KUBOTA Dealer.
6. Always use the seat belt if the tractor has a CAB or
ROPS. Do not use the seat belt if there is no CAB or
ROPS. Check the seat belt regularly and replace if
frayed or damaged.
SAFE OPERATION-2
(1) CAB
(2) Seat belt
C Working
1. Pull only from the drawbar. Never hitch to axle housing
or any other point except drawbar; such arrangements
will increase the risk of serious personal injury or death
due to a tractor upset.
2. OPERATING THE TRACTOR
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
both the clutch and the Power Take-Off (PTO) are
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" in "EVERY 50
HOURS" in "PERIODIC SERVICE" section.)
Do not operate unless they are functioning correctly.
(1) Drawbar
2. For trailing PTO-driven implements, set the drawbar to
the towing position.
3. Attach pulled or towed loads to the drawbar only.
4. Keep all shields and guards in place. Replace any that
are missing or damaged.
5. Avoid sudden starts. To avoid upsets, slow down
when turning, on uneven ground, and before stopping.
6. The tractor cannot turn with the rear wheel or 4-wheel
differential locked and attempting to do so could be
dangerous.
7. 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.
8. Watch where you are going at all times. Watch for and
avoid obstacles. Be alert at row ends, near trees, and
other obstructions.
9. When working in groups, always let the others know
what you are going to do before you do it.
10.Never try to get on or off a moving tractor.
11.Always sit in the operator's seat when operating levers
or controls.
12.Do not use "Bi-speed Turn" at high speed.
13."Bi-Speed Turn" enables short and fast turns,
therefore, become familiar with its performance before
operating in close or confined areas.
14.Do not stand between tractor and implement or trailed
vehicle unless parking brake is applied.
-3SAFE OPERATION
C Instructional seat (if equipped)
1. Always wear your seat belt and stabilize your body by
holding the handrail on the CAB frame.
2. It is not intended to carry children nor any other person
for any other purpose.
3. The left hand door must be closed at all time whenever
the instructional seat is occupied and the tractor is in
motion.
4. Do not permit others to ride, except on the designated
instructional seat.
5. Use caution to avoid the risks of obstructing operator's
view, falling from the machine and interfering with
controls.
6. Do not start and stop the tractor suddenly, nor take
sharp turn.
7. Do not use the instructional seat if the seat belt or the
door lock fails to function.
8. Do not use the instructional seat for transport.
9. When opening and closing the door from the
instructional-seat-sitting position, move the door
slowly. This is to prevent his or her hand(s) from
getting caught by the door or his or her body to hit
against the door.
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.
6. Never allow children to play on the machine or on the
implement.
7. Use extra caution when backing up. Look behind and
down to make sure area is clear before moving.
C Operating on slopes
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
All slopes require extra caution.
1. To avoid upsets, always back up steep slopes. If you
cannot back up the slope or if you feel uneasy on it, do
not operate on it. Stay off slopes too steep for safe
operation.
2. Driving forward out of a ditch, mired condition or up a
steep slope increases the risk of a tractor to be upset
backward. Always back out of these situations. Extra
caution is required with 4-wheel drive models because
their increased traction can give the operator false
confidence in the tractor's ability to climb slopes.
3. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed, direction or apply
brake and make sudden motions of the steering
wheel.
4. Avoid disengaging the clutch or changing gears speed
when climbing or going down a slope. If on a slope
disengaging the clutch or changing gears to neutral
could cause loss of control.
5. Special attention should be made to the weight and
location of implements and loads as such will affect the
stability of the tractor.
6. To improve stability on slope, set widest wheel tread
as shown in "TIRES, WHEELS AND BALLAST"
section.
Follow recommendations for proper ballasting.
7. To avoid free wheeling:
A Do not shift the shuttle lever while on a slope.
A Stop completely by using the brake and by
depressing the clutch pedal, then shift the shuttle
lever.
A Start off after selecting shuttle direction, by
releasing the clutch pedal.
C Driving the tractor on the road
1. Lock the 2 brake pedals together to help assure
straight-line stops. Uneven braking at road speeds
could cause the tractor to tip over.
(1) Brake Pedal (LH)
(2) Brake Pedal (RH)
(3) Brake Pedal Lock
(A) Whenever travelling on the road
2. Check the front wheel engagement. The braking
characteristics are different between 2 and 4-wheel
drive. Be aware of the difference and use carefully.
3. Always slow the tractor down before turning. Turning
at high speed may tip the tractor over.
SAFE OPERATION-4
4. Make sure that the Slow Moving Vehicle (SMV) sign is
clean and visible. Use hazard lights and turn signals as
required.
(1) SMV emblem
(2) Bracket
(1) 3-point hitch lowering lock lever (A) "LOCK"
(B) "UNLOCK"
5. Observe all local traffic and safety regulations.
6. Turn the headlights on. Dim them when meeting
another vehicle.
7. Drive at speeds that allow you to maintain control at all
times.
8. Do not apply the differential lock while traveling at road
speeds. The tractor may run out of control.
9. Avoid sudden motions of the steering wheel as they
can lead to a dangerous loss of stability. The risk is
especially great when the tractor is traveling at road
speeds.
10.Do not operate an implement while the tractor is on the
road. Lock the 3-point hitch in the raised position.
11.When towing other equipment, use a safety chain and
place an SMV emblem on it as well.
3. PARKING THE TRACTOR
1. Disengage the PTO, lower all implements to the
ground, place all control levers in their neutral
positions, set the parking brake, stop the engine,
remove the key from the ignition and lock the cab door
(if equipped). Leaving transmission in gear with the
engine stopped will not prevent tractor from rolling.
2. Make sure that the tractor has come to a complete
stop before dismounting.
3. Avoid parking on steep slopes, if at all possible park on
a firm and level surface; if not, park across a slope and
chock the wheels.
Failure to comply with this warning may allow the
tractor to move and could cause injury or death.
(1) Safety chain
12.Set the implement lowering control in the "LOCK"
position to hold the implement in the raised position.
-5SAFE OPERATION
4. OPERATING THE PTO
1. Wait until all moving components have completely
stopped before getting off the tractor, connecting,
disconnecting, adjusting, cleaning, or servicing any
PTO driven equipment.
2. Keep the PTO shaft cover in place at all times.
Replace the PTO shaft cap when the shaft is not in
use.
(1) PTO Shaft cover
(2) PTO Shaft cap
(A) "NORMAL POSITION"
(B) "RAISED POSITION"
5. USING 3-POINT HITCH
1. Use the 3-point hitch only with equipment designed for
3-point hitch usage.
2. When using a 3-point hitch mounted implement, be
sure to install the proper counterbalance weight on the
front of the tractor.
3. To avoid injury from separation:
Do not extend lift rod beyond the groove on the
threaded rod.
(1) Groove
3. Before installing or using PTO driven equipment, read
the manufacturer's manual and review the safety
labels attached to the equipment.
To prevent PTO driven equipment from improper or
unsafe use, select the lower speed (540rpm) unless
the higher one is specifically recommended as safe by
the equipment manufacturer.
4. When operating stationary PTO driven equipment,
always apply the tractor parking brake and place
chocks behind and in front of the rear wheels. Stay
clear of all rotating parts. Never step over rotating
parts.
4. Use [UP-DOWN] switch or lever only on farm fields.
For all other application, use hydraulic lever to move
attachment.
6. SERVICING THE TRACTOR
Before servicing the tractor, park it on a firm, flat and level
surface, set the parking brake, lower all implements to the
ground, place the gear shift lever in neutral, stop the
engine and remove the key.
1. Allow the tractor time to cool off before working on or
near the engine, muffler, radiator, etc.
2. Do not remove radiator cap while coolant is hot. When
cool, slowly rotate cap to the first stop and allow
sufficient time for excess pressure to escape before
removing the cap completely. If the tractor has a
coolant recovery tank, add coolant or water to the tank,
not the radiator. (See "Checking Coolant Level" in
"DAILY CHECK" in "PERIODIC SERVICE" section.)
3. Always stop the engine before refueling. Avoid spills
and overfilling.
4. Do not smoke when working around battery or when
refueling. Keep all sparks and flames away from
battery and fuel tank. The battery presents an
explosive hazard, because it gives off hydrogen and
oxygen especially when recharging.
5. Before "jump starting" a dead battery, read and follow
all of the instructions. (See "JUMP STARTING" in
"OPERATING THE ENGINE" section.)
SAFE OPERATION-6
6. Keep first aid kit and fire extinguisher handy at all
times.
7. Disconnect the battery's ground cable before working
on or near electric components.
8. To avoid the possibility of battery explosion, do not use
or charge the refillable type battery if the fluid level is
below the LOWER ( lower limit level ) mark. Check the
fluid level regularly and add distilled water as required
so that the fluid level is between the UPPER and
LOWER levels.
9. To avoid sparks from an accidental short circuit,
always disconnect the battery's ground cable (-) first
and reconnect it last.
(1) Battery
11.Always maintain the correct tire pressure. Do not
inflate tires above the recommended pressure shown
in the operator's manual.
12.Securely support the tractor when either changing
wheels or adjusting the wheel tread width.
13.Make sure that wheel bolts have been tightened to the
specified torque.
14.Disconnect the battery's ground cable and stop the
engine to avoid the possibility of the machine runaway
due to 4WD braking system during testing, service or
repair with only rear wheels off the ground.
15.Do not work under any hydraulically supported
devices. They can settle, suddenly leak down, or be
accidentally lowered. If it is necessary to work under
tractor or any machine elements for servicing or
adjustment, securely support them with stands or
suitable blocking beforehand.
16.Escaping hydraulic fluid under pressure has sufficient
force to penetrate skin, causing serious personal
injury. Before disconnecting hydraulic lines, be sure to
release all residual pressure. Before applying
pressure to the hydraulic system, make sure that all
connections are tight and that all lines, pipes, and
hoses are free of damage.
(1) Battery
10.Do not attempt to mount a tire on a rim. This should be
done by a qualified person with the proper equipment.
17.Fluid escaping from pinholes may be invisible. Do not
use hands to search for suspected leaks; use a piece
of cardboard or wood. Use of safety goggles or other
eye protection is also highly recommended. If injured
by escaping fluid, see a medical doctor at once. This
fluid will produce gangrene or severe allergic reaction.

(2) Hydraulic line
(3) Magnifying glass
-7SAFE OPERATION
18.Do not open high-pressure fuel system.
High-pressure fluid remaining in fuel lines can cause
serious injury. Do not disconnect nor attempt to repair
fuel lines, sensors, or any other components between
the high-pressure fuel pump and injectors on engines
with high pressure common rail fuel system.
19.To avoid hazardous high voltage, turn the key switch
to the OFF position if it is necessary to check to repair
the computer, harness or connectors.
20.During Diesel Particulate Filter (hereinafter called
DPF) regenerating operations, exhaust gases and
exhaust filter components reach temperatures hot
enough to burn people, or ignite or melt common
materials.
21.Keep the tractor away from people, animals or
structures which may be susceptible to harm or
damage from hot exhaust gases.
22.To prevent fires, keep the DPF/SCR muffler and its
surroundings clear of anything flammable and keep
clean at all times. [Selective Catalytic Reduction
(hereinafter called SCR)]
23.During regeneration, white exhaust gas may be
visible. Do not allow regeneration in a non-ventilated
space.
24.During regeneration, do not leave the tractor.
25.Before servicing a tractor equipped with the front
suspension, be sure to lower the machine to the lowest
position.
26.The front suspension hydraulic circuit is still under high
pressure after the engine has stopped. Do not
disconnect the pipes and/or hoses because you may
get injured by high-pressure oil. If pipes and/or hoses
are found worn or damaged, consult your local
KUBOTA Dealer for this service.
