STOPPING THE ENGINE
1. After slowing the engine to idle, turn the starter key
to the “STOP” position.
2. Remove the starter key.
NOTE :
• If the starter key does not stop the engine,
consult your local KUBOTA Dealer.
WARMING UP OF THE ENGINE
WARNING
To avoid personal injury or death:
• Be sure to set the parking brake during warm-
up of the engine.
• Be sure to set all shift levers to the “NEUTRAL”
positions and to place the PTO-clutch-control-
switch in the “OFF” position during warm-up of
the engine.
For 5 minutes after the engine start-up, allow the
engine to warm up without applying any load. Allowing
the engine to warm up is to allow the oil to reach every
engine-part. If the load should be applied to the engine
without the warm-up period of 5 minutes, trouble such
as seizure, breakage, or premature wear may develop.
1. Warm-up of the engine and
transmission oil in the low
temperature range
IMPORTANT :
• Do not operate the tractor under full load
condition until it is sufficiently warmed up.
Hydraulic oil serves as transmission fluid. In cold
weather, the oil may be cold with increased viscosity.
The oil with increased viscosity can cause delayed oil
circulation or abnormally low hydraulic pressure for
some time after engine start-up. Delayed oil circulation
or abnormally low hydraulic pressure in turn can result
in trouble in the hydraulic system. Also, since the lip of
the oil seal does not follow at low oil temperature, oil
leakage might occur if the shaft is rotated at high speed
during low temperature. To prevent these troubles in
the hydraulic system, check the following instructions.
Warm up the engine at about 50% of rated rpm
according to the following table.

JUMP STARTING THE ENGINE
When jump starting the engine, follow the instructions
in this section to safely start the engine.
WARNING
To avoid personal injury or death:
• Battery gases can explode. Keep cigarettes,
sparks, and flames away from battery.
• If the tractor battery is frozen, do not jump start
the engine.
• Do not connect the other end of the negative (-)
jumper cable to the negative (-) terminal of the
tractor battery.
IMPORTANT :
• This machine is equipped a 12 volt negative (-)
ground starting system.
• Use only the same voltage for jump starting.
• Use of a higher voltage source on the electrical
system of the tractor could result in severe
damage to the electrical system of the tractor.
Use only matching voltage source when jump
starting in a low battery condition or a dead
battery condition.
• Do not operate the tractor with the battery cable
disconnected from the battery.
• Do not operate the tractor without the battery
mounted.
• Do not operate the tractor with the battery dead.
Charge the battery fully enough before
operating the tractor.
Otherwise the tractor might malfunction.
Connect cables in numerical order.
Disconnect in reverse order after use.
