OPERATING THE ENGINE

Check Easy Checker(TM) Lamps:

1. When the key is turned "ON", lamps (2) (3) (4) (5) (6)

only should come on. If trouble should occur at any
location while the engine is running, the warning lamp
corresponding to that location comes on.

Daily checks with the Easy Checker(TM) only, are not
sufficient. Never fail to conduct daily checks carefully
by referring to Daily Check section.
(See "DAILY CHECK" in "PERIODIC SERVICE OF
THE TRACTOR" section.)

For the appropriate preheating time, refer to the table
below:

Glow plug indicator (2) comes on while engine is being
preheated.

Because of safety devices, the engine will not start
except when the speed control pedal is in "NEUTRAL"
position and the PTO clutch lever is in "OFF" position
respectively.

Cold Weather Starting

When the ambient temperature is below -5 and the
engine is very cold. If the engine fails to start after 10
seconds, turn off the key for 30 seconds. Then repeat
steps 8 and 9. To protect the battery and the starter, make
sure that the starter is not continuously turned for more
than 30 seconds.

Block Heater (Option)

A block heater is available as an option from your dealer.
It will assist you in starting your tractor when the ambient
temperature is below -15 .

If the lamp is still "ON", immediately stop the engine and
determine the cause.

STOPPING THE ENGINE

If key does not stop the engine, consult your local
KUBOTA Dealer.

(1) Turn signal/Hazard light indicator
(2) Preheat
(3) Electrical charge
(4) Engine oil pressure
(5) Coolant temperature indicator
(6) Low fuel indicator
(7) Key switch

8. Turn the key to "PREHEAT" position

and hold it for about 2 to 3 seconds.

Easy Checker(TM) are "OFF".

1. After slowing the engine to idle, turn the

key to "OFF".

2. Remove the key.

OPERATING THE ENGINE

WARMING UP

To avoid personal injury:
A

Be sure to set the parking brake during warm-
up.

Be sure to set all shift levers to "NEUTRAL"
positions and to place PTO lever in "OFF"
position during warm-up.

For 5 minutes after engine start-up, allow engine to warm
up without applying any load, this is to allow oil to reach
every engine part. If load should be applied to the engine
without this warm-up period, trouble such as seizure,
breakage or premature wear may develop.

Warm-up and Transmission Oil in the Low

Temperature Range

Hydraulic oil serves as transmission fluid. In cold weather,
the oil may be cold with increased viscosity. This can
cause delayed oil circulation or abnormally low hydraulic
pressure for some time after engine start-up. This in turn
can result in premature wear in the hydraulic system or
malfunctions such as resistance in the speed control
pedal and difficulty engaging the range gear shift lever. To
prevent the above, observe the following instructions:
Warm up the engine at about 50% of rated rpm according
to the table below:

Do not operate the tractor under full load condition until
it is sufficiently warmed up.

JUMP STARTING

To avoid personal injury:
A

Battery gases can explode. Keep cigarettes,
sparks, and flames away from battery.

If tractor battery is frozen, do not jump start
engine.

Do not connect other end of negative (-) jumper
cable to negative (-) terminal of tractor battery.

When carrying on the following steps 4 and 11,
do not allow the positive (+) terminal of the
battery to touch other parts.

When jump starting engine, follow the instructions below
to safely start the engine.
1. Bring helper vehicle with a battery of the same voltage

as disabled tractor within easy cable reach. "THE
VEHICLES MUST NOT TOUCH".

2. Engage the parking brakes of both vehicles and put

the shift levers in "NEUTRAL". Shut both engines off.

3. Put on safety goggles and rubber gloves.
4. Take the dead battery out and put it on the step.
5. Ensure the vent caps are securely in place. (if

equipped)

6. Attach the red clamp to the positive (red, (+) or pos.)

terminal of the dead battery and clamp the other end
of the same cable to the positive (red, (+) or pos.)
terminal of the helper battery.

7. Clamp the other cable to the negative (black, (-) or

neg.) terminal of the helper battery.

8. Clamp the other end to the engine block or frame of

the disabled tractor as far from the dead battery as
possible.

9. Start the helper vehicle and let its engine run for a few

moments. Start the disabled tractor.

10. Disconnect the jumper cables in the exact reverse

order of attachment. (Steps 8, 7 and 6).

11. Put the battery back and fix it.

This machine has a 12volt negative (-) ground starting
system.

Use only same voltage for jump starting.

Use of a higher voltage source on tractors electrical
system could result in severe damage to tractors
electrical system.
Use only matching voltage source when "Jump
starting" a low or dead battery condition.

OPERATING THE TRACTOR

OPERATING THE TRACTOR

OPERATING NEW TRACTOR

How a new tractor is handled and maintained determines
the life of the tractor.
A new tractor just off the factory production line has been,
of course, tested, but the various parts are not broken in,
so care should be taken to operate the tractor for the first
50 hours at a slower speed and avoid excessive work or
operation until the various parts become "broken-in." The
manner in which the tractor is handled during the
"breaking-in" period greatly affects the life of your tractor.
Therefore, to obtain the maximum performance and the
longest life of the tractor, it is very important to properly
break-in your tractor. In handling a new tractor, the
following precautions should be observed.

Do not Operate the Tractor at Full Speed

for the First 50 Hours.

Do not start quickly nor apply the brakes suddenly.

In winter, operate the tractor after fully warming up the
engine.

Do not run the engine at speeds faster than
necessary.

On rough roads, slow down to suitable speeds.
Do not operate the tractor at fast speed.

The above precautions are not limited only to new
tractors, but to all tractors. But it should be especially
observed in the case of new tractors.

Changing Lubricating Oil for New Tractors

The lubricating oil is especially important in the case of a
new tractor. The various parts are not "broken-in" and are
not accustomed to each other; small metal grit may
develop during the operation of the tractor; and this may
wear out or damage the parts. Therefore, care should be
taken to change the lubricating oil a little earlier than
would ordinarily be required.
For further details of change interval hours, See
"MAINTENANCE OF THE TRACTOR" section.

BOARDING AND LEAVING THE TRACTOR

1. Never try to get on or off a moving tractor or jump off

the tractor to exit.

2. Face the tractor when getting into or out of the tractor.

Do not use the controls as hand holds to prevent
inadvertent machine movements.

3. Always keep steps and floor clean to avoid slippery

conditions.

OPERATING FOLDABLE ROPS

To avoid personal injury:
A

When raising or folding the ROPS, apply
parking brake, stop the engine and remove the
key.
Always perform function from a stable position
at the rear of tractor.

Fold the ROPS down only when absolutely
necessary and fold it up and lock it again as
soon as possible.

Before proceeding to fold ROPS, check for any
possible interference with installed
implements and attachments.
If interference occurs, contact your KUBOTA
Dealer.

To Fold the ROPS

1. Loosen the holding knob bolts.
