Abstract
An apparatus for distributing liquid manure including a mobile spreader tank to contain the liquid manure and adapted to be drawn by a tractor. A frame is supported by the three-point hitch of the tractor, and a series of soil working elements are mounted on the frame and are adapted to penetrate the soil when the frame is lowered. A delivery tube for the liquid manure is positioned behind each soil working element, and a flexible conduit connects each delivery tube with a valve controlled outlet in the tank. The liquid manure is delivered through the conduit system to the delivery tubes by an auger located within the tank, or alternately, by pressurizing the spreader tank.
