Driving the tractor

Starting the engine

Before starting the engine carry out the pre-operational
checks as set out in chapter 'Safe operation of your
tractor'.
(1) Sit on the driver seat.
(2) Apply the footbrake.
(3) Put the hydraulic lever in the down position.
(4) Put the main gear lever in neutral.
(5) Insert the ignition key and turn it on.
(6) Ensure that the warning lights are working.
(7) Operator need to turn key to the ''ON'' position. The
glow circuit automatically activates.
Operator need to wait for glow light to turn off. As the lamp
goes off turn the key to the start position to start the
engine.
(8) Ensure that all the warning lights are off with the
engine running.
Important:
Never turn the key to the start position while the engine is running as this can cause serious damage
to the starter and engine flywheel.
Only engage the starter for a period of not more than 10 seconds.
If Engine does not start, rest the starter for about 20 seconds and try again for a maximum of 10
seconds.
If the engine does not start after repeated attempts, refer to the fault tracing guide.
Important: Especially in cold weather, always allow the tractor to idle for a while to warm up &
build up sufficient oil pressure to ensure normal operating temperature for longer engine life.

Stopping the engine

- After light work let the engine idle for a while and turn the key off.
Important: After long or heavy work allow the engine to idle for 5- 10 minutes and turn the key
off.

Warming up

When starting the engine allow it to warm up to operating temperature by allowing it to idle 5-10 minutes to
ensure full lubrication and operating temperature. Failure to do so can shorten engine life substantially.

Warming up in cold weather

Cold weather will change the viscosity of the oil, resulting in a reduced oil pumping capacity, which can
cause damage to the engine if it is not warmed up correctly. It also causes problems with the hydraulic
system and the synchromesh in the transmission.
Correct times for warming up are:
Temperature
Above 50°F
50°F ~ 32°F
32°F ~ 14°F
14°F ~ -4°F
Below - 4°F
