PRINCIPLE OF OPERATION
Two vertical spinning beaters at the rear of the spreader expel manure in a uniform spread pattern. Each
beater is driven by a hydraulic motor. A PTO driven hydraulic power supply on the spreader provides power
to the beaters. The hydraulic pump is two stage thereby supplying independent power to each beater motor.
A wide heavy duty belt covers the box floor. At the front of the spreader, this belt is attached to a sliding
gate. At the rear, this belt goes around a winged idler pulley and on the lower side is connected to a drive
chain. At the front of the spreader, this chain is driven by a hydraulic motor driving a planetary gear box and
sprocket that is powered by the tractor hydraulic system. Driving the belt toward the rear of the spreader
pulls the sliding gate rearward to move the load toward the beaters. A manually adjustable flow control in the
drive chain motor circuit regulates the speed the gate moves.
An end gate at the rear of the spreader is raised and lowered by two hydraulic cylinders, powered by the
tractor hydraulic system. This gate must be lowered during loading to prevent packing of the material into
the beaters and to help prevent leakage during transport.
