8. Fully depress the clutch pedal, turn the key to
“PREHEAT” position and hold it for about 2 to 3
seconds.
For the appropriate preheating time, see to the
following table.
Temperature Preheating time
Over 0
℃
(32
℉
) 2 to 3 seconds
0
℃
to -5
℃
(32
℉
to 23
℉
)
5 seconds
-5

10 seconds
NOTE :
• Glow plug indicator (5) comes on while
engine is being preheated.
9. Turn the key to “START” position and release when
the engine starts.
IMPORTANT :
• Because of the safety devices, the engine
will not start except when the PTO lever is
placed in the “OFF” position and speed
control lever is placed in the “NEUTRAL”
position.
Cold weather starting
• When the ambient temperature is below -5
℃
(23
℉
) and the engine is very cold. If the engine
fails to start, 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
10 seconds.
1. 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
℃
(5
℉
).
1. Check to see that all the lamps on the Easy
Checker are “OFF” .
If a lamp is still on, immediately stop the engine and
determine the cause.
STOPPING THE ENGINE
1. After slowing the engine to idle, turn the key to
“OFF” .
2. Remove the key.
WARMING UP OF THE ENGINE
WARNING
To avoid personal injury or death:
• Be sure to set the parking brake during warmup
of the engine.
• Be sure to set all shift levers to the “NEUTRAL”
positions 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 transmission oil at low
ambient temperatures
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. To prevent the
trouble in the hydraulic system, observe the following
instructions.
Warm up the engine at about 50% of rated rpm
according to the following table.
Ambient temperature Warm-up time requirement
