Abstract: A combine harvester having a rotary separating mechanism operable to separate grain from crop material and to propel straw in a desired path for discharge from the machine through a discharge opening is disclosed wherein a rotary straw discharge assist beater is located below said desired path and between the separating mechanism and the discharge opening to assist in the propelling of straw in a rearward direction. The assist beater prevents straw from accumulating on the rear wheel axle of the combine and helps feed straw into a rearwardly located straw chopper. For combines having a pair of transversely spaced discharge openings, a pair of assist beaters can be provided.
