1. Cold weather starting of the
engine
When the ambient temperature is as follows and the
engine is very cold, you may fail to start the engine.
Ambient temperature below -5 ℃ (23 ℉)
To protect the battery and the starter, make sure not to
turn the starter continuously for more than following
seconds.
Continuous turning limit of the starter 30 seconds
2. Block heater (option)
A block heater is available as an option from your
dealer.
The block heater will assist you in starting your tractor
when the ambient temperature is as follows.
Ambient temperature below -15 ℃ (5 ℉)
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 serious 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-lever in
the off position during warm-up of the
engine.
For five 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 oil to reach every
engine-part.
If the load should be applied to the engine without
preceding warm-up period, 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 hydraulic oil may be cold with increased
viscosity. The hydraulic 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 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 premature wear
in the hydraulic system or malfunctions of controls,
check the following instructions.
Warm up the engine at about 50% of rated rpm
according to the following table.
Ambient temperature Warm-up time requirement
Above 0 ℃ (32 ℉) At least 5 minutes
-10 ℃ to 0 ℃
(14 ℉ to 32 ℉)
5 minutes to 10 minutes
-20 ℃ to -10 ℃
(-4 ℉ to 14 ℉)
10 minutes to 15 minutes
Below -20 ℃ (-4 ℉) More than 15 minutes
JUMP STARTING THE ENGINE
Follow the instructions of jump starting of the engine to
safely start the engine.
WARNING
To avoid serious 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 other end of negative (-) jumper
cable to negative (-) terminal of the tractor
battery.
• When taking the dead battery, putting the
battery, and fixing the battery, do not allow the
positive (+) terminal of the battery to touch
other parts.
• To prevent short circuit, before connecting
jumper cables, make sure to remove the metal-
battery-holder.
IMPORTANT :
• The tractor equips a 12 volt negative (-) ground
starting system.
