ABSTRACT:
A straw spreader for the rear straw discharge of a combine comprises a frame mounted on ground wheels together with a pair of hitch arms which extend forwardly from the frame on either side of the rear portion of the combine for attachment to the combine frame structure. The separate frame can thus move up and down relative to the rear of the combine and maintains a pair of spreader spinners on the frame at a predetermined height relative to the ground. Guide surfaces collect the material from the chopper at the rear of the combine and direct it onto the spinners for a spreading action. The low height of the spreading action reduces dust emission and enhances spreading consistency. An accumulator can be provided between the spreader and the discharge in the rear of the combine to allow the amount of straw spread to be varied relative to the amount collected at any particular point on the field.
