plug. Hydraulic oil selective control valve of the tractor's external hydraulic system is used to
control the extending of the support cylinder.
Lowering the straight hydraulic support (1) is done by opening the valve (3) on the spreader
frame. Hydraulic oil supplied from hydraulic selective control valve extends the cylinder ram
to the desired height. After the pressure in hydraulic conduit is reduced, withdrawal of the
parking stand to transport position is forced by means of springs – figure (3.4).
TIP
The hydraulic system of the support is filled with L-HL32 Lotos hydraulic oil.
3.2.5 HYDRAULIC SYSTEM OF TAILGATE (SYSTEM CONTROLLED FROM THE
TRACTOR)
The hydraulic system of the tailgate controls raising and lowering of the manure spreader's
tailgate. The hydraulic system is supplied with oil from the tractor external hydraulic system.
The system is controlled from the tractor cab using the manifold lever. Pressurised oil is
supplied through hydraulic conduit (4) marked with information decal (5) to hydraulic
cylinders (2), which raise the tailgate (1). The tailgate is lowered after the pressure in
hydraulic conduit is reduced.
The system is equipped with a hydraulic cut-off valve (3) which prevents a sudden closing of
the tailgate while performing maintenance work.
ATTENTION
During service with the tailgate raised, protect it from falling down by closing the cut-off
valve and with a suitable mechanical support which is durable and stably mounted.
Take care not to lower or rise the tailgate when it is locked using a cut-off valve.
Otherwise, hydraulic cylinders and/or tailgate may be damaged.
