Abstract
An agricultural harvester includes a threshing and separating system for separating grain from non-grain crop material, and a residue handling system for receiving at least a portion of the non-grain crop material. The residue handling system includes a chopper and a windrow arrangement, each having an inlet. A door is movable between a closed position which directs the non-grain crop material to the chopper and an open position which directs the non-grain crop material to the windrow arrangement. A feed roller is positioned adjacent to and between the inlet of the chopper and windrow arrangement. The feed roller is rotatable in a first direction which directs the non-grain crop material to the chopper when the door is in the closed position, and a second direction which directs the non-grain crop material to the windrow arrangement when the door is in the open position.
