Abstract
An agricultural combine has a chassis that supports a feederhouse receiving cut crop material from an agricultural harvesting head. A rotor and concave arrangement receives the cut crop material to thresh the cut crop material and to separate the cut crop material into a flow of grain and a flow of straw. A cleaning shoe receives the flow of grain from the threshing and separating mechanism to clean the flow of grain and to provide a flow of clean grain and a flow of chaff. A residue management system receives the flow of straw and the flow of chaff. The residue management system has a straw chopper that rotates in a first direction in a windrowing mode to windrow the flow of straw and rotates in a second direction opposite the first direction in a chopping mode to chop the flow of straw.
