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.

A combine harvester including a straw spreader, the combine harvester comprising a housing, a straw discharge opening at a rear end of the housing, a straw chopper and discharge assembly mounted adjacent the opening for projecting chopped straw rearwardly of the housing out of the opening, the straw spreader comprising a frame, at least one ground wheel on the frame for engaging the ground and supporting the frame at a predetermined height relative to the ground independently of changes in height of the discharge opening from the ground, hitch means for coupling the frame to a rear part of the combine for transportation behind the combine, rotatable spreader means mounted on the frame at a vertical height below a vertical height of the discharge opening for discharging straw in a spread pattern outwardly to a least one side of the frame and guide surface means shaped and arranged to engage the straw as it is projected rearwardly of the housing and to redirect the straw downwardly on to the spreader means. A method of spreading straw from a combine harvester comprising collecting from a portion of ground a crop including straw therein, chopping and discharging the straw rearwardly from a rear discharge opening of the combine harvester, collecting the straw as it is discharged from the discharge opening on storage means carried behind the combine harvester on a frame having at least one ground wheel for support of the frame relative to the ground and trailed behind the combine harvester, accumulating a volume of the collected straw on the storage means, discharging the collected straw from the storage means in a spread pattern across the ground behind the storage means, and varying the amount of straw discharged from the storage means relative to the amount of straw collected from the discharge opening of the combine harvester so as to vary the amount of straw spread on the portion of the ground relative to the amount of straw collected from the portion of the ground.
