Braking system
WARNING:
!
1. Before driving on the road, always latch the brake pedals together.
2. Independent braking may only be used to assist turning on headlands of a
tractor with mounted implements.
3. When the tractor is operated for stationary work, even if only for short periods
always engage the parking brake
When attaching a trailer, or trailed machines to the tractor, ensure that the trailer air braking system
is connected.
To connect the trailer braking system to the tractor braking system, proceed as follows:
engage the parking brake (this will cause the air pressure in the hose drop down to the
atmospheric pressure,
couple the trailer and tractor air couplers,
release the parking brake.
WARNING:
!
Never start towing of a trailer with the air pressure gauge pointer in red zone. Allow
time for the compressor to fill the air reservoir. Insufficient air pressure in the
system is then also indicated by air pressure drop warning light which illuminates
red.
Front drive axle
The drive to the front wheels is transmitted from the drop box by the drive shaft, crown wheel and
pinion and differential mechanism to the front axle final reduction units. As a standard equipment the
“limited slip” type of differential is fitted (self-locking).
WARNING:
!
Operation in four wheel drive is intended for field work only. Do not use the tractor in
four wheel drive on roads or dry land.
Rear differential lock
If during the field work one of the rear wheels starts to slip (there is a small difference in rotational
speed) engage the differential lock by pressing the differential lock pedal down firmly,
In case one of the wheels is slipping significantly (there is considerable difference in rotational speed)
proceed as follows:
fully depress the clutch pedal,
engage the differential lock by pressing its pedal down,
release the clutch pedal slowly, while maintaining foot pressure on the differential lock pedal.
To disengage the differential lock release the pedal. If the lock fails to disengage, steer slightly to
either left or right or depress for a moment one of the brake pedals (independent).
WARNING:
!
1. Do not attempt to engage the differential lock with one wheel spinning fast and the
other stopped.
2. Do not attempt to turn with the differential lock engaged.
