Abstract: A re-threshing system for a combine includes a delivery mechanism for transporting tailings from the cleaning section of the combine to a re-threshing apparatus and a bypass that can be used to bypass the tailings around the re-threshing apparatus. The re-threshing apparatus includes a re-threshing housing that at least partially surrounds a re-threshing rotor. The rotor and housing have cooperating threshing elements that act to re-thresh the tailings delivered into the housing and deliver the re-threshed tailings out of a housing outlet into a discharge passage to be directed to the cleaning section of the combine harvester. The delivery mechanism is configured to throw or fling the tailings into an inlet opening of the housing in a direction substantially tangential to the rotor rotating direction. To bypass the re-threshing apparatus, a deflector can be deployed to block the inlet opening and deflect the tailings into a bypass passage that is open to the discharge passage.

Abstract: A straw chopper for an agricultural harvesting unit includes a housing, and a rotor carried by the housing. The rotor includes a center chopping section and a pair of fans respectively positioned at longitudinally outboard ends of the center chopping section. Each fan includes a hub rotatable in a direction of rotation, and a plurality of fan blades connected with the hub at a plurality of angularly spaced locations about the hub. Each fan blade has a generally U-shaped portion with a rear wall and a pair of side walls extending from the rear wall in the direction of rotation.

Abstract: A straw chopper for an agricultural harvesting machine includes a housing, a rotor carried by the housing, and a stationary knife bank. The rotor includes a plurality of pendulously mounted knife blades. The stationary knife bank includes a plurality of stationary knife blades adjustably movable toward and away from the rotor. The stationary knife bank includes a tension rod extending longitudinally through the stationary knife bank and having a threaded end, and at least one wing nut threadingly engaged with the threaded end.

Abstract: A cleanout configuration is provided for a grain compartment on a harvesting apparatus. The grain compartment has walls that form a trough, and a vertically arranged auger that is supported on an auger casting located in a sump at a bottom of the trough. Wall portions, in the form of a unitary casting with the auger casting are adjacent to the auger casting and comprise cleanout openings covered by removable covers. The openings are in a grate pattern. The unitary casting can be a bridge member, which supports all, or a substantial amount of the weight of the unitary casting and the auger.
