2.27.3 Rear PTO mechanical control.
Rear PTO mechanical control is exercised by lever 3 (figure 2.27.1).
The rules of rear PTO engagement with mechanical control are specified in subsec-
tion 2.17.2 “Rear power takeoff engagement”.
2.27.4 RLL fixing mechanism control in transport position.
This mechanism is intended to fix RLL in transport position to prevent lowering of
mounted implements.
Lever fixing mechanism of RLL in transport position 8 (figure 2.27.1) has 2 modes:
- “RLL unlocked” – the extreme right position as viewed along tractor movement;
- “RLL locked in upper (transport) position” – the extreme left position.
For RLL locking in transport position do the following:
- lift the implement into the extreme upper position, setting draft control unit handle
4 in the position “Uplift”;
- after fixing RLL in the extreme upper position, turn lever 8 left;
- leave lever 4;
To unlock RLL uplift the implement with handle 4 and turn lever 8 right.
2.27.5 Adjustable implement lifting limiter.
Adjustable implement lifting limiter is mounted on tractor “BELARUS-952.5” with draft
control unit against order.
Limitation of retraction stroke of mounting mechanism rear cylinder rod (the height of
implement lifting) is exercised with adjustable pawl 2 (figure 2.27.2), following the procedure:
- loosen winged nut 4;
- shift adjustable stop 2 along hydraulic cylinder 3 rod into the required position and
tighten winged nut 4 by hand. While lifting the implement onto the required height, adjust-
able stop 2 will shift hydromechanical valve 1 and lock cylinder cavities.
1 – hydromechanical valve rod; 2 – adjustable stop; 3 – hydraulic cylinder; 4 –
winged nut

ATTENTION: TO AVOID CAB DAMAGE WITH ELEMENTS OF UPLIFTED IM-
PLEMENTS, ADJUST THE LENGTH OF LEFT AND RIGHT LIFTING RODS IN ACCOR-
DANCE WITH INSTRUCTIONS OF ARTICLE 4.3.3.2 “LIFTING ROD” !
