STEERING SYSTEM
PRONAR P5 type tractors are equipped with a hydrostatic steering system with Danfoss, Rexroth or
WPA dosing pumps allowing steering of the tractor when the engine is not running. The system is
equipped with a hydraulic pump (permanently engaged) driven by the tractor engine. It is possible to
change the inclination angle of the steering wheel and the setting along the steering column axis to the
most comfortable position for the operator.
To change the inclination angle use the pull rod 1 (Figure 4-23) pulling
towards yourself and hold. To change the position of the steering wheel
setting, release pull rod and lock it with small movements. The angle
change mechanism has 4 positions (in a range of angle settings), in
which the steering wheel is locked. One may choose one of these 4
settings in the range from 25
°
to 40
°
every 5
°
.
Figure 4-23 Steering column inclination lock pull rod.
Change setting of steering wheel along axis requires (Figure 4-24):
•
loosening steering wheel axis cover and the screw 1;
•
setting steering wheel in chosen setting in the adjustment range of 100
mm;
•
tightening the cover with screw 1 (manually).

BRAKES
Working brake (basic)
During road travel brake pedals should be locked with the catch (Figure 4-25)
During fieldwork, if necessity arises of making small radius turns one
may brake after unlocking the catch, the left or the right wheel, by
pressing the appropriate pedal.
One should brake smoothly, without jerks, pressing the pedal to the
end and not holding it in intermediate positions. Do not rest feet on
pedals unnecessarily. This leads to an accelerated wear on brake disk
abrasive linings.
Figure 4-25 Catch locking working brake pedals.
ATTENTION: Before road travel the working (foot) brake pedal catch must be locked.
Parking brake (emergency)
The parking brake is installed on the left side of the seat. It immobilises the tractor while parking.
Do NOT use parking brake to stop the tractor in motion. An
exception is an emergency situation, when while travelling, the
working (basic) brake is ineffective or is damaged without any prior
fault symptoms.
The parking brake is operated by pulling lever upwards. To release
brake lever pull slightly upwards then press the button 1 located at
the end of the lever and push it down completely. (Figure 4-26)
