A liquid manure spreading apparatus having a tank and a pump selectively operable to evacuate air from within the tank or supply air to the tank. A safety shut off valve located in the tank having a ball and an elongated float confined in a cage is operable to block the evacuation of air from the tank when the tank is full of liquid manure. A control valve mounted on the pump has a single spool selectively moveable with a handle to an air evacuating position and an air supplying position. A single air line is connected to the valve and tank.
