ABSTRACT:
A pair of straw and chaff spreaders for a combine are operable to distribute straw and chaff in an even and wide spread pattern on the ground behind the combine. Each spreader has an upright shaft drivably coupled to upper and lower dishes. Flexible arms on the upper disk distribute straw. Rigid channel shaped arms on the lower disk propels chaff and small particulate materials in the pattern. The turning channel shaped arms also generate an air stream which distributes straw and chaff in the wide spread pattern.
