SAFE 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 they have
experienced, 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.
PRECAUTIONS BEFORE
OPERATING THE TRACTOR
Know your equipment and its limitations.
Read this entire manual before starting and operating
the tractor.
1. General precautions
• Pay special attention to the safety labels on the
tractor.
• Do not operate the tractor or any implement
attached to the tractor while under the influence of
alcohol, medication, controlled substances, or while
you are fatigued.
• Before allowing other people to use your tractor,
explain them how to operate it and have them read
this manual before operating it.
• Never wear loose, torn, or bulky clothing around the
tractor. Loose, torn, or bulky clothing may catch on
moving parts or controls, leading to the risk of an
accident. Use additional safety items: hard hat,
safety boots or shoes, eye and hearing protection,
gloves, and so on, as appropriate or required.
• Do not allow passengers to ride on any part of the
tractor at anytime. The operator must remain in the
tractor seat during operating the tractor.
• 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 SERVICE INTERVALS on
page 71)
• Keep your tractor clean. Buildups of dirt, grease,
and trash may contribute to fires and lead to
personal injury.
• Use only implements meeting the specifications
listed under IMPLEMENT LIMITATION TABLES on
page 22, or implements approved by KUBOTA.
• 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
manual or the attachment manual.
• 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 WHEEL ADJUSTMENT on page 66)
(1) Rear wheels (A) Tread width
• Do not modify the tractor. Unauthorized
modification may affect the function of the tractor,
which may result in personal injury.
2. Precautions for CAB and ROPS
KUBOTA recommends the use of a CAB or roll-over-
protective-structures (ROPS), and seat belt in almost
all applications. Combination of a CAB or ROPS and
seat belt will reduce the risk of serious injury or death if
the tractor should be upset.
• Check for overhead clearance which may interfere
with a CAB or ROPS.
• Set the parking brake and stop the engine. Remove
any obstructions which may prevent raising or
folding the ROPS. Do not allow any bystander.
Always perform functions of CAB or ROPS from a
stable position at the rear of the tractor. Hold the
top of the ROPS securely when raising or folding it.
Make sure that all pins are installed and locked.
• If the CAB or ROPS is loosened or removed for any
reason, make sure that all parts are reinstalled
correctly before operating the tractor.
• Never modify or repair any structural member of a
CAB or ROPS because welding, bending, drilling,
grinding, or cutting it may weaken the structure.
SAFE OPERATION
L2501

• If any structural member of the CAB or ROPS is
damaged, replace the entire structure at your local
KUBOTA Dealer.
• If the tractor is equipped with a foldable ROPS, you
may fold down it temporarily only when absolutely
necessary to fold down it for areas with constraints
on height.
There is no protection of operator provided by the
ROPS in the folded position. For operator safety,
you should place the ROPS in the upright and
locked position and fasten the seat belt for all other
operations.
• Always use the seat belt if the tractor is equipped
with 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.

PRECAUTIONS FOR
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,
and so on.
This manual sets forth some of the obvious risks, but
the list of risks is not exhaustive, and the list of risks
cannot be exhaustive. It is the operator's responsibility
to be alert for any equipment or environmental
condition that could compromise safe operation.
1. Precautions for starting to operate
the tractor
• Always sit in the operator's seat when starting the
engine or operating levers or controls. Adjust the
operator's seat according to Operator's seat on
page 32. Never start the engine while you are
standing on the ground.
• 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 is equipped with a
CAB or a foldable ROPS in the upright and locked
position.
• Do not start the engine by shorting across starter
terminals or bypassing the safety start switch. The
tractor may start in gear and move if normal starting
circuitry is bypassed.
• Do not operate or idle the engine in a non-
ventilated area. Carbon monoxide gas is colorless,
odorless, and deadly.
• Check that the operator-presence-control-system
(OPC) are functioning correctly before each time
you use the tractor. Test the safety systems.
–[Manual transmission type]
See Checking the engine start system [Manual
transmission type] on page 85 and Checking
the operator presence control on page 86.
–[HST type]
See Checking the engine start system [HST
type] on page 86 and Checking the operator
presence control on page 86.
Do not operate unless they are functioning
correctly.
2. Precautions for working the
tractor
• Pull only from the drawbar. Never hitch to axle
housing or any other point except drawbar. Hitching
to axle housing or any other point except drawbar
will increase the risk of serious personal injury or
death due to a tractor upset.
(1) Drawbar
• For trailing the PTO-driven implements, set the
drawbar to the towing position.
• Attach pulled or towed loads to the drawbar only.
• Keep all shields and guards in place. Replace any
shield or guard that are missing or damaged.
