Dead start of tractor in regular operation - clutch pedal
In regular operation use the clutch pedal only for stopping the tractor. For the need of delicate
inching, e.g. when connecting the tools or when manipulating with tractor in crammed spaces, if
even the reduced gears are not slow enough, use the clutch pedal only for short time.
It is forbidden to control the speed of tractor by partial depression of clutch pedal with engine
revolutions higher than 1200 rpm. Do not use the clutch pedal as a foot rest. There is a risk of limited
service life or failures of travel clutches.
Dead start - using the clutch pedal
1. Start the engine.
2. Depress the clutch pedal.
3. Select road and reduced speeds.
4. Shift an applicable gear for starting the tractor.
5. Shift the reversing lever to the direction requested (forward or backward).
6. Slightly increase the engine revolutions.
7. Prepare the manual brake for unbraking.
8. Release the clutch pedal only to the point of travel engagement and with simultaneous increase of
revolutions continue in a continuous release of the clutch pedal.
9. Fully unbrake the manual brake.
