3.7 HYDRAULIC SYSTEM OF THE SHEAR TYPE DRAWBAR

SUPPORT

The parking stand hydraulic system is
used to control the support to set drawbar
at the correct height. Support hydraulic
system is fed by the tractor hydraulic
system through the hydraulic lines (1) and
(2). The line have plugs (7) secured with
red plugs (8).
Raising or lowering the support is done
by extending or retracting the hydraulic

cylinder piston rod (4). Hydraulic oil se-
lective control valve of the tractor external
hydraulic system is used to control the
support cylinder.
The system is equipped with a hydraulic

TIP

The hydraulic system of the shear type drawbar sup-

port is filled with L-HL32 Lotos hydraulic oil.
