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

Control of front driving axle

The front driving axle in the basic position is activated.
Activation of the front driving axle is indicated with the activated symbol on the switch and the symbol in the
instrument panel display. Switching-off is performed with the switch on the instrument panel.
a - front driving axle switched off
b - front driving axle switched on
The front driving axle of the decommissioned tractor (tractor is braked, engine is stopped, key in '0' position)
is switched on.
During sudden drop of air pressure in the air-pressure system of the tractor, the front driving
axle is automatically switched on.

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!
