A return pan for an agricultural combine includes a textured floor, two augers, and two motors coupled to the two augers, respectively, to selectively drive the motors in rotation.

An agricultural harvester includes a chassis, a cleaning system carried by the chassis, a crop material elevator supplied with crop material that has passed through the cleaning system and has a first inlet and a second inlet, and an auger system supplying the crop material from the cleaning system to the crop material elevator. The auger system includes a first auger defining an auger axis that extends in a conveying direction toward the crop material elevator and is configured to supply crop material to the first inlet, a second auger defining a second auger axis that extends in the conveying direction, and a crop material conveyor configured to supply crop material from the second auger to the second inlet generally transverse to the second auger axis.

An agricultural harvester includes a chassis, a cleaning system carried by the chassis, and a crop material elevator for receiving crop material that has passed through the cleaning system. The crop material elevator has a top-most end, a bottom-most end, a first inlet between the top-most end and the bottom-most end, and a second inlet between the top-most end and the first inlet. The agricultural harvester also includes an auger system for supplying crop material from the cleaning system to the crop material elevator. The auger system includes a first auger defining an auger axis for supplying crop material to the first inlet, a second auger defining a second auger axis, and a crop material conveyor for supplying crop material from the second auger to the second inlet.

A threshing and separating system for an agricultural harvester includes a rotor configured to rotate about a rotor axis, a rotor cage at least partially enclosing the rotor and including a tailings return inlet formed therein and configured to couple to a tailings return elevator and an insert opening formed therein that is at least partially circumferentially aligned with the tailings return inlet relative to the rotor axis, at least one concave coupled to the rotor cage and defining a plurality of concave perforations, and a threshing insert removably coupled to the rotor cage and including at least one mounting opening. The threshing insert at least partially covers the insert opening and is positioned such that material from the tailings return inlet travels past the threshing insert before reaching the concave.

An agricultural combine has a cleaning shoe including an upper sieve or chaffer over a lower sieve. The lower sieve is over a clean gain chute. A return chute open to a return opening is under the clean grain chute. The clean grain chute receives clean grain from the chaffer and the lower sieve. The return chute receives unclean grain and tailings from the cleaning shoe through the return opening. The chaffer's rear extremity extends beyond the lower sieve's rear extremity configured with a sieve chute. The sieve chute is spaced under the chaffer's rear extremity and extends rearward and angularly upward above the return opening toward the chaffer's rear extremity from the lower sieve's rear extremity, allowing the sieve chute to intercept grain from the chaffer and divert it forward to the lower sieve and away from the return opening.

A grain cleaning system in a combine harvester including a frame, a chaffer sieve, and a lower sieve. A clean grain chute is located under the lower sieve to catch grain falling therefrom and is inclined to direct the caught grain to a clean grain trough. A tailings return chute is disposed under the clean grain chute and is configured to direct tailings to a tailings collection trough. A multi-configurable plate is mounted to the frame and positioned under a rear portion of the chaffer sieve. The plate is moveable between different operating positions. In a first operating position the plate is configured to guide material incident thereon to the tailings return chute. In a second operating position the plate is configured to guide material incident thereon to the clean grain chute.
