ABSTRACT:
Apparatus for spreading manure comprises an elongate hopper 12 mounted on a mobile frame. An axial feed rotor 18 runs along the inside of the base of the hopper and urges manure forwardly to a transfer rotor 25 which pushes the material sideways through an opening 21 to an overshot impeller 23 which throws the manure sideways from the apparatus. On the axial feed rotor 18 are blades 19 extending outwardly from the axis of the rotor and inclined in such a manner as to push the material along the direction of the axis. The blades 19 are positioned on a reverse helical path around the rotor axis, the sense of the reverse helical path being opposite to the sense of inclination of the individual blades. In this arrangement the efficiency of axial delivery of the rotor 18 is substantially lower than if the blades were positioned along a helical path around the rotor axis having the same sense as the inclination of the individual blades. The reduced efficiency of axial delivery of the rotor can be matched to the capability of the sideways-directed impeller 23.
