Control Of Front Driving Axle; Driving With Engaged Front Driving Axle; Foot Brakes - Zetor Proxima GP Series Operator's Manual

Control of front driving axle

The front driving axle is engaged in the basic position.
Engagement of the front driving axle is indicated by an
illuminated symbol on the switch.
It can be disengaged using a switch on the dashboard.
a - Front driving axle engaged
b - Front driving axle disengaged
At the stopped tractor, the front driving axle is engaged at
stopped tractor (braked tractor, stopped engine, key
switch in '0' position).
In case of a drop of air pressure in the
compressed air system of the tractor the front driving
axle is engaged automatically.

Driving with engaged front driving axle

Use the front driving axle with slipping of the
rear wheels to increase the traction force of the
tractor. It is permitted to engage the front driving axle
on roads and hard surfaces up to 15 km/h (travel with
engaged front driving axle causes increased wearing
of front tyres).
Permanent engagement of the front driving axle is
permitted if there is a farming mechanism attached to the
front suspension. This condition is mentioned in the
instructions manual to the respective mechanism.
Maximum permitted speed when driving with these
attachments is 15 km/h.

Foot brakes

The foot brakes are disk wet type, hydraulic-controlled,
with two pedals and automatic pressure balancer.
During travel both pedal have to be coupled
with a latch. Use uncoupled pedals for barking of the
right or left wheel only when working in terrain and on
a field at low travel speeds.
Note: When driving from a steep downslope with a trailer
or semi-trailer equipped with air or hydraulic brakes it is
necessary to start braking by foot brake already from
beginning of the slope!
With braking by one brake pedal the trailer
brakes are not activated!
