Manure spreader with vertical expellers

Apparatus for spreading selected material onto a field comprising:

• a. a wheeled frame for being pulled over the field;
• b. a box supported by the frame for storing the material therein, the box having front and back walls, opposed side walls, and a floor, the box back wall having inside and outside surfaces and a discharge opening of a predetermined height therethrough;
• c. gate means for selectively opening and closing the discharge opening in the box back wall;
• d. expeller means mounted to the outside of the box back wall adjacent the discharge opening therein for rotating about vertical axes entirely outside of the box;
• and
• e. auger means located on the box floor for propelling materials stored in the box through the back wall discharge opening to the expeller means to be spread thereby onto the field, wherein the expeller means comprises a pair of expellers having respective vertical axes and located adjacent and in generally horizontal alignment with the discharge opening in the box back wall to receive material propelled by the auger means through the box back wall discharge opening and to fling the material onto the field, each expeller having an axial length that is at least one-half of the height of the discharge opening.
