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.
4.4 Power take-off (PTO).
Power take-
off shaft is placed in the rear axle housing and it’s end rotates to the right (from rear of
the tractor), diameter 35 mm with 6 splines as per PN-77/R-36101 standard with ring groove for
safety attachment of the driven implement telescopic-articulated shaft.
PTO shaft is covered with the PTO guard (4 - Fig.4.6.2) and secured with a PTO cup (3 -Fig.4.6.2)
(when PTO is not operated)
NOTE:
1. After attaching mounted implement carefully raise and lower it using Position Control
lever. Check clearance and the drive shaft slide range/articulation.
2. When attaching trailed implements ensure the drawbar is correctly set.
3. Check all four wheels when carrying out stationary PTO work.
