SAFE OPERATION
-1SAFE 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. 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 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.
SAFE OPERATION-2
(1) ROPS
(2) Seat belt
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. 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
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" in "EVERY 50
HOURS" in "PERIODIC SERVICE OF THE
TRACTOR" section.)
Do not operate unless they are functioning correctly.
(1) Hitch
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.
-3SAFE OPERATION
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 four-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 changing gears speed when climbing or going
down a slope. If on a slope 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.
11.Set the implement lowering speed knob in the "LOCK"
position to hold the implement in the raised position.
(1) 3-point hitch lowering speed knob (A) "FAST"
(B) "SLOW"
(C) "LOCK"
C Driving the tractor on the road
1. Check the front wheel engagement. The braking
characteristics are different between two and four
wheel drive. Be aware of the difference and use
carefully.
2. Always slow the tractor down before turning. Turning
at high speed may tip the tractor over.
3. On public roads use the hazard lights, if required by
local traffic and safety regulations.
4. Observe all local traffic and safety regulations.
5. Turn the headlights on.
6. Drive at speeds that allow you to maintain control at all
times.
7. Do not apply the differential lock while traveling at road
speeds. The tractor may run out of control.
8. 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.
9. Keep the ROPS in the "UP" position and wear the seat
belt when driving the tractor on the road.
Otherwise, you will not be protected in the event of a
tractor roll-over.
10.Do not operate an implement while the tractor is on the
road. Lock the 3-point hitch in the raised position.
SAFE OPERATION-4
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).
(1) Brake pedal
(2) Parking brake pedal
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 with
chock the wheels.
Failure to comply with this warning may allow the
tractor to move and could cause injury or death.
(A) "DEPRESS"
(B) "PUSH FORWARD WHILE
DEPRESSING (1)"
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
3. Before installing or using PTO driven equipment, read
the manufacturer's manual and review the safety
labels attached to the equipment.
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.
(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.
-5SAFE OPERATION
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) Groove
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 OF THE
TRACTOR" 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.)
6. Keep first aid kit and fire extinguisher handy at all
times.
(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.
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.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.
SAFE OPERATION-6
15.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.
16.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.

LOADER
Most loader equipment accidents can be avoided by following simple safety precautions.
These safety precautions, if followed at all times, will help you operate your loader safely.
1. BEFORE OPERATING THE LOADER 2. OPERATING THE LOADER
-7SAFE OPERATION
1. Read and understand all instructions and precautions
found in both the tractor and the loader operator's
manuals before using the loader.
Lack of knowledge can lead to accidents.
2. It is the owner's responsibility to ensure that anyone
who will operate the loader reads this manual first and
becomes familiar with the safe operation of the loader.
3. For your safety, a ROPS with a seat belt is strongly
recommended by KUBOTA in almost all applications.
If your tractor has a foldable ROPS, fold it down only
when absolutely necessary and raise it up and lock it
again as soon as possible. Do not wear the seat belt
when a foldable ROPS is down or a fixed ROPS is
removed. If you have any questions, consult your local
KUBOTA dealer.
Always use the seat belt when the tractor is equipped
with a ROPS. Never use the seat belt when the tractor
is not equipped with a ROPS.
4. Visually check for hydraulic leaks and broken, missing,
or malfunctioning parts.
Make necessary repairs before operating.
5. Replace damaged or illegible safety labels. See
following pages for required labels.
6. When the front loader is mounted on the tractor, enter
and exit the operator's seat only from left side of the
tractor.
7. Engage the loader control valve lock to prevent
accidental actuation when the implement is not in use
or during transport. Do not utilize the valve lock for
machine maintenance or repair.
8. Assemble, remove and reinstall the loader only as
directed in this manual. Failure to do this could result
in serious personal injury or death.
9. Check that all nuts, bolts, and pins are properly fitted
and tightened to specification.
10.Ensure that the approved counterweight and tires are
fitted to the tractor.
11.Remove mid mount mower deck (if fitted) before
operating the loader.
1. Operate the loader only when properly seated at the
controls. Do not operate from the ground.
2. Move and turn the tractor at low speeds. (less than 10
km/h)
3. Never allow anyone to get under the loader bucket or
reach through the boom when the bucket is raised.
4. Keep children, others and livestock away when
operating loader and tractor.
5. Do not walk or work under a raised loader bucket or
attachment unless it is securely blocked and held in
position.
6. For tractor stability and operator safety, a counter
weight of the recommended size must be added to the
3-point hitch when using loader.
7. To increase stability adjust the rear wheels to the
widest setting that is suitable for your application.
8. Exercise extra caution when operating the loader with
a raised bucket or attachment.
9. Do not lift or carry any person on the loader, in the
bucket, or other attachment.
10.Avoid loose fill, rocks and holes. They can be
dangerous for loader operation or movement.
11.Avoid overhead wires and obstacles when the loader
is raised. Contacting electric lines can cause
electrocution.
12.Gradually stop the loader boom when lowering or
lifting.
13.Use caution when handling loose or shiftable loads.
14.Using loaders for handling large, heavy, or shiftable
objects is not recommended without proper handling
attachments.
15.Handling large heavy objects can be extremely
dangerous due to :
A Danger of rolling the tractor over.
A Danger of upending the tractor.
A Danger of the object rolling or sliding down the
loader boom onto the operator.
16.If you must perform this sort of work (item 15), protect
yourself by :
A Never lift the load higher than necessary to clear
the ground.
A Ensure that the Rated Operating Load is not
exceeded.
A Always use the recommended counter weight.
A Never lift large objects with equipment that may
permit them to roll back onto the operator.
A Move slowly and carefully, avoiding rough terrain.
17.Never lift or pull a load from any point on the loader
with a chain, rope, or cable. Doing so could cause a
rollover or serious damage to the loader.
SAFE OPERATION-8
18.Be extra careful when operating the tractor on a slope,
always operate up and down, never across the slope.
Do not operate on steep slopes or unstable surfaces.
19.When operating another implement on a hillside, be
sure to remove the loader to reduce the risk of rollover.
20.Carry loader boom at a low position during transport.
(You should be able to see over the bucket.)
21.Allow for the loader length when making turns.
3. AFTER OPERATING THE LOADER
1. When loader work is complete and parking or storing,
choose flat and hard ground. Lower the loader boom
to the ground, stop the engine, set the brakes and
remove the key before leaving the tractor seat.
2. Make sure the detached loader is on stands and on a
hard, level surface.
3. Before disconnecting hydraulic lines, relieve all
hydraulic pressure by moving the controls.
4. Do not remove the loader from the tractor without an
approved bucket attached.
4. SERVICING THE LOADER
1. Always wear safety goggles when servicing or
repairing the machine.
2. Do not modify the loader. Unauthorized modification
may affect the function of the loader, which may result
in personal injury.
3. Do not use the loader as a work platform or a jack to
support the tractor for servicing or maintenance.
Securely support the tractor or any machine elements
with stands or suitable blocking before working
underneath.
For your safety, do not work under any hydraulically
supported devices. They can settle or suddenly leak
down or be accidentally lowered.
4. Escaping hydraulic oil under pressure can have
sufficient force to penetrate the skin, causing serious
personal injury. Do not use hands to search for
suspected leaks. If injured by escaping fluid, obtain
medical treatment immediately.
5. Do not tamper with the relief valve setting. The relief
valve is pre-set at the factory. Changing the setting
can cause overloading of the loader and tractor which
may result in serious personal injury.
6. When servicing or replacing pins in cylinder ends,
bucket, etc., always use a brass drift and hammer.
Failure to do so could result in injury from flying metal
fragments.
BACKHOE
Most backhoe equipment accidents can be avoided by following simple safety precautions.
These safety precautions, if followed at all times, will help you operate your backhoe safely.
-9SAFE OPERATION
1. BEFORE OPERATING BACKHOE
1. Read and understand all precautions in this manual
before service or operation. Allow only trained
personnel to operate or service this equipment.
2. It is the owner’s responsibility to ensure that anyone
who will operate the backhoe reads this manual first
and becomes familiar with the safe operation of the
backhoe.
3. For safe operation, check the mounting bolts for
tightness and that the mount levers are in the right
position before operation.
4. Never operate tractor with backhoe attached and
loader removed.
5. Check for buried material such as electrical,
telephone, gas and water lines. When in doubt,
contact local utility companies for their buried location
prior to operating the backhoe.
6. Replace any safety decal that becomes damaged, lost
or illegible. Also renew all decals when repainting.
2. OPERATING THE BACKHOE
1. Do not allow anyone other than the operator on the
unit while in operation or transport.
2. Keep all person and animals away from swing area of
backhoe.
3. Use care when operating on slopes to avoid tip-over.
Travel at a speed compatible with safe operation,
especially when operating on uneven terrain, crossing
ditches or while turning.
4. Operate the backhoe from the backhoe operator's seat
only.
5. When using on slopes, one stabilizer may be lower
than the other. Use extreme care during excavation as
risk of tip-over will increase.
6. To reduce the risk of tip-over on a slope, place the
spoil to the high side of the excavation.
7. Do not dig under the stabilizer or tractor, especially in
soft or sandy condition. Take extra precaution in wet or
thawing ground.
These conditions can become unstable and may
collapse under the weight of the machine and may
cause tip over.
8. Never operate the machine or any equipment while
under the influence of alcohol or other drugs, or while
fatigued.
9. When leaving the machine unattended, be sure to
lower the backhoe to the ground. Set the parking
brake, then shut the engine off and remove the key.
3. DRIVING THE TRACTOR ON THE ROAD
1. Raise and center the boom, close the dipperstick, curl
the bucket and engage the boom and swing locks
before transporting the machine.
2. Check the local codes or regulations that may apply to
tractor / loader / backhoe operation on public streets or
highways, before transporting or traveling. Use SMV
emblem and warning flashers as required.
(SMV : Slow Moving Vehicle)
4. SERVICING THE BACKHOE
1. Before disconnecting hydraulic lines, relieve all
hydraulic pressure by moving the controls.
2. Always use personal protection device such as safety
goggles and ear protection when servicing or repairing
the machine.
3. Lower the backhoe to the ground and shut the engine
off before servicing.
4. When servicing or repairing pins in cylinder ends,
bucket, etc., always use a brass drift and hammer.
Failure to do so could result in injury from flying metal
fragments.
5. To avoid serious personal injury, keep clear of working
area of the backhoe.
6. When servicing or checking underneath, do not get
under the machine while it is being held with only the
bucket, backhoe or stabilizers. Securely support with
jack stands.
7. For your safety, do not work under any hydraulically
supported machine elements. They can settle,
suddenly leak down, or be accidentally lowered.
8. Escaping hydraulic fluid under pressure can have
sufficient force to penetrate the skin, causing serious
personal injury. Before applying pressure to the
system, be sure that all connections are tight and that
lines, pipes and hoses are not damaged. Fluid
escaping from a very small hole can be almost
invisible. Do not use hands to search for suspected
leaks, use a piece of cardboard or wood. If injured by
escaping fluid, see a doctor at once. Serious infection
or allergic reaction will develop if proper medical
treatment is not administered immediately.
9. Do not tamper with any backhoe control valve relief
pressure setting. The relief valve pressure is preset at
the factory. Changing the setting can cause
overloading of the backhoe and the tractor, and
serious personal injury or death may result.
10.Do not modify the backhoe for any reason. Modifying
the backhoe can cause an unstable condition of the
tractor / loader / backhoe combination and serious
personal injury or death may result.
