Driving with engaged front driving axle
Use the front driving axle when tyre slip of rear wheels occurs to increase the pulling power of
the tractor.
Driving with the activated front driving axle is not recommended on the road or on a hard surface
(driving with the activated front driving axle causes increased wear of front tyres).
The front driving axle can be permanently activated if a front carried agricultural machine or tool is connected
to the tractor. This condition is stated in the instructions for use of the corresponding machine. The maximum
permitted speed of these combinations of vehicles is 15 km.h
-1
.
If the travelling speed exceeds 20 km/h, the drive of the front axle is automatically disconnected.
Automatic deactivation of the drive is indicated by flashing of the symbol on the display of the instrument
panel (2) and of the symbol on the button.
When the symbols stop flashing, the drive of the front axle is automatically disconnected.
If the travelling speed drops below 20 km/h, the drive of the front axle can be connected by repeated
pressing of the button (1).
If the travelling speed is higher than 20 km/h, the drive of the front axle can be connected by repeated
pressing of the flashing button.
Press the flashing button for a long time (about 3 s) to activate the drive of the front axle permanently for the
whole driving time of the tractor (without automatical deactivation).
The drive of the front axle remains activated even if the travelling speed exceeds 20 km/h.
This state is indicated by the activated symbol PERM (3) on the display of the instrument panel.
Manual brake - signalization
If the tractor is not braked by a manual brake, a warning is
displayed on a display (a letter
P in a circle) and at the
same time there is a sound signal.
This situation occurs in two cases
a - a tractor unbraked by a manual brake with engine
running and a driver leaves its seat
b - a tractor unbraked by a manual brake standing with
engine off and the key is shifted in '0' position.
Brake the tractor with a manual brake.
