ABSTRACT:
A liquid manure spreader having a tank for carrying liquid manure. An auger assembly driven by a power takeoff from a tractor delivers the manure to a pump mounted on the back of the tank. The pump discharges the material through a spreading structure. A valve operated by a hydraulic cylinder controls the flow of manure from the pump to the spreading structure. The spreading structure has a horizontal plate that directs the material in a wide, relatively low spread pattern onto the ground. The tank has a fill hole equipped with a safety grid assembly.
