1. Antifrost heater for oil separator
(if equipped)
The heater element operates continuously when the
key switch is in the “ON” or “START” position.
Due to high electrical draw, extended idle time or
operations will drain the battery and stop the tractor.
(1) Heater (Oil separator, out) (2) Heater (Oil separator, in)
2. Block heater (if equipped)
A block heater is available as an option from your
dealer.
Block heater will assist you in starting your tractor when
the ambient temperature is as follows.
Ambient temperature
Below -20 ℃ (-4 ℉)
STOPPING THE ENGINE
1. After slowing the engine to idle, turn the starter key
to the “OFF” 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 set the PTO gear-shift lever 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 the engine 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. Such condition 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.
Ambient temperature Warm-up time requirement
Above 0 ℃ (32 ℉) At least 10 minutes
0 ℃ to -10 ℃
(32 ℉ to 14 ℉)
10 minutes to 20 minutes
-10 ℃ to -20 ℃
(-14 ℉ to -4 ℉)
20 minutes to 30 minutes
Below -20 ℃ (-4 ℉) More than 30 minutes
