IMPORTANT
Movement direction of loaded feeding mechanism may be reversed only for a short
time.
The feeding mechanism may be started only if the manure spreader's slide gate is
raised. Otherwise, the manure spreader may be seriously damaged.
3.2.3 HYDRAULIC SYSTEM OF FEEDING MECHANISM (SYSTEM CONTROLLED
FROM THE TRACTOR)
Hydraulic system of feeding mechanism is used for controlling the floor conveyor. The
system is supplied by the external tractor hydraulic system through the hydraulic conduits (5)
and (6). Decals (item 23 - table (2.1)) in the form of arrows indicating the direction of
hydraulic oil flow are located on conduits, near the connection plugs, in order to identify the
conduits. The system is connected to hydraulic motor (2) which drives the floor conveyor.
The system is equipped with an overload valve (3) which protects the system against
excessive increase of pressure above the rated operating pressure of the manure spreader.
If the flow is blocked and pressure in the system has achieved the limit level, the overload
valve opens and releases excess of oil to return conduit. In this way, the complete system is
protected against overload and possible damage.
The system is controlled by means of the manifold in the tractor cab. Such a solution enables
change of conveyor movement direction and shortens reaction time. The conveyor speed is
adjusted using a knob on hydraulic flow regulator (1) within scale from 0 to 10. The flow
regulator is installed on the conduit outrigger in the front section of the manure spreader. The
maximum flow rate (maximum conveyor speed) is achieved if flow regulator setting is 10,
while the minimum flow rate is achieved if flow regulator setting is 0. Design and diagram of
hydraulic system of feeding mechanism is shown in figure (3.3).
