Interrupted sound signal
PHS18N052
If the tractor speed is regulated by partial released clutch pedal at higher engine revolutions than
1,200 rpm, an interrupted audio signal is generated and a warning on the display of the instrument
panel is shown. If this situation occurs, immediately fully pres the clutch pedal to the end or release
the clutch pedal to its upper position and wait until the acoustic signal is deactivated. Decrease
engine revolutions below 1,200 rpm and then continue in operation with the tractor. If you do not do
this, after 8 seconds the interrupted acoustic indication changes to uninterrupted indication.
Dead start of the tractor
If at dead start, engine revolutions are higher than 1400 rpm L gear of multiplier is automatically shifted, not
depending on the switch of multiplier pre-selection on dashboard being on or off . If the multiplier pre-
selection switch on the dashboard is on at dead start, L gear of multiplier is shifted automatically
independent on the number of engine revolutions at dead start (i.e. when the engine revolutions are lower
than 1400 rpm).
A very fast dead start can cause overloading of driving gear, increased fuel consumption,
excessive wear of tyres and damage to load. Use dead start on the 1
st
gear only when driving with
heavy trailer to the slope and in difficult terrain.
Dead start of tractor in regular operation - automatic dead start function
- Use the control of travel clutch by reversing lever under the steering wheel for dead start of the tractor.
- Select the slowliest L gear of torque multiplier for dead start of the tractor.
Note: When starting or stopping the engine of the tractor, the fastest gear H is always automatically shifted.
- If the road and reducing speeds shifting lever is shifted in the group of road speeds, shift the lowest gear
speed for tractor dead start with respect for operational conditions.
- Use the lowest possible engine revolutions for tractor´s dead start, such that there is no turn off. After the
switch of travel clutch, increase the engine revolutions according to your needs.
Dead start by means of automatic dead start function
Automatic dead start function is in the shift of reversing lever with engaged applicable gear followed by dead
start without using the clutch pedal or clutch control buttons.
1. Start the engine.
2. Shift appropriate gear for starting the engine.
3. Release the manual brake, if you are standing on a slope, brake the tractor by foot brake.
4. When shifting the reversing lever form neutral to the requested direction of tractor drive (forward or
backward), the tractor starts.
5. When you increase the engine revolutions simultaneously, release the foot brake.
When depressing the clutch pedal, the automatic dead start function is put off from operation.
