Change the direction of drive by means of reversing lever

Change the direction of drive by means of reversing lever is done with travel speed lower than
10km/h. When you attempt to change the direction of drive in speed higher than 10 km/h, acoustic
signal starts (uninterrupted tone) and the tractor engages neutral. The signal switches off after the
shift of reversing lever back to N position, when depressing the clutch pedal or pressing the button
of switching clutch on the head of gear shifting lever. It is also necessary to lower the travel speed of
tractor under 10km/h, shift the reversing lever to neutral position and to repeat the shifting of
requested direction.
Keeping the following instructions when changing the direction of the drive, contributes to
prolonging service life of travel clutches.
· For changing the direction of the drive of tractor use reversing lever under the steering wheel without using
the clutch pedal.
· For changing the direction of the drive of tractor, select the slowliest gear L with torque multiplier.
· For changing the direction of the drive of tractor, select lower gear with regard for the subsequent dead
start and tractor load.
Changing the direction of drive by means of reversing lever is done at tractor travel speed
lower than 10km/h. When you try to change the direction of drive at the speed of more than 10 km/h,
an acoustic signal starts (uninterrupted tone), the signal switches off after the shift of the lever back
to N position, when depressing the clutch pedal or pressing the button for switching off the clutch on
the head of the gear shifting lever.
1. Lower the travel speed of tractor under 10km/h by means of brake pedal.
2. Shift the reversing lever to the requested direction of tractor drive.
3. The tractor stops automatically and travels in the requested direction.
4. Continue in smooth dead start of the tractor with simultaneous incresae of engine revolutions.
Should the tractor speed drop below 10km/h, tractor shift neutral and it is necessary to lower
the travel speed of tractor under 10km/h, shift the reversing lever to neutral position and to repeat
the shifting to the required direction.
When depressing the clutch pedal, the automatic function is put off operation. If the above
mentioned is done subsequently after the attempt to change the direction of drive above 10 km/h, it
is necessary to lower the travelling speed of tractor below this speed. In opposite case, after the
release of clutch pedal the neutral remains shifted.

Change the direction of drive - using the clutch pedal

1. Depress the clutch pedal and stop the tractor by foot brake.
2. Shift the reversing lever to the requested direction of tractor drive.
3. Release the clutch pedal only to the point of travel engagement and with simultaneous increase of engine
revolutions continue in smooth release of the clutch pedal.
4. Start smoothly and slowly.

Gear shifting

- When shifting, press and hold the clutch control knob on the gearshift lever, release the accelerator pedal,
disengage the gear, engage the gear, release the button, and then increase the engine speed.
- If the operating conditions allow, use the multiplier preselection function.

Gear shifting - Using the clutch pedal

Depress the clutch pedal (clutch disengaged). At the same time release the pedal of foot throttle and shift the
applicable gear speed. Release the clutch pedal smoothly (clutch is being engaged) and at the same time
increase the engine revolutions.
