Abstract

An embodiment includes a combine including a sensor positioned to detect a physical characteristic of a windrow produced by the combine or an operational state of the combine, a windrow door for expelling the residue from the combine, a windrow door actuator coupled to the windrow door to position the windrow door at a windrow door angle, a windrow chute for receiving the expelled residue from the windrow door and guiding the residue into a windrow, a windrow chute actuator coupled to the windrow chute to position the windrow chute at a windrow chute angle, a controller configured to determine a physical characteristic of the windrow or the operational state of the combine based on an output of the sensor, and adjust at least one of the windrow door angle or the windrow chute angle based on the determined physical characteristic or operational state.
