Abstract: A cleaning system for use in an agricultural combine harvester comprises a crop-processing platform and a rotatable finger. The crop-processing platform is arranged to receive crop material thereon and reciprocate in a fore-aft manner to process crop material. The finger auger extends laterally in proximity to the crop-processing platform and comprises flighting of fingers arranged to convey crop material laterally upon rotation of the finger auger.

Abstract: A cleaning system for an agricultural combine harvester includes a pan and a crop divider. The pan includes a stepped floor to receive crop material thereon and is arranged for fore-aft reciprocating movement to advance the crop material in a crop-processing direction. The crop divider is mounted with the pan for fore-aft reciprocating movement therewith and extends in a fore-aft manner and above the stepped floor to partition the crop material laterally. The crop divider includes a body and a periphery disposed about the body. The body includes a multi-dimensional, clustered array of crop strokers extending laterally to engage the crop material to advance the crop material in the crop-processing direction during fore-aft reciprocating movement of the pan.
