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.

Abstract: A windrow chute assembly includes a plurality of movable chute sections. A first chute section has a first proximal end for receiving material, and a first distal end opposite the first proximal end. The second chute section has a second proximal end for receiving material, and a second distal end opposite the second proximal end. The first and second proximal ends define a transverse axis therebetween. The first and second chute sections are displaceable toward one another to a closed or partially closed configuration to control the width and placement of each windrow. The first and second chute sections are also displaceable away from one another to an open configuration to provide access to rear areas of the combine.

Abstract: A chopper knife assembly for use by an agricultural harvester. The chopper knife assembly includes a mounting lug with a fulcrum, wedge, and counterwedge; and at least one bladed knife attached to the mounting lug between the wedge and counterwedge; the assembly is held in place by an attachment means. The bladed knives are able to pivot on the fulcrum of the mounting lug during use, thereby forcing the knife blades onto the counterwedges to provide a more secure retention means.
