Abstract: A multi-tier crop residue flow guide for a rotary crop residue spreader of an agricultural combine including an element disposed in a housing and rotatable in a predetermined direction about an axis which is oriented horizontally or at a small acute angle to horizontal for driving a flow of crop residue through a discharge opening of the housing located at a predetermined angular position around the axis, the flow guide including at least two guide surfaces or tiers having inlet ends disposed in at least generally axially side by side relation adjacent to the discharge opening in position for directing portions of the flow of crop residue in generally the predetermined direction radially outwardly and away from the opening, respectively, each of the flow guides having a curved surface connected to the inlet end thereof and extending generally in the predetermined direction radially outwardly and away from the discharge opening to a discharge end spaced radially outwardly from the spreader for directing the re

Abstract: A variably positionable chaff pan for attachment to an oscillating element of a cleaning apparatus or system of an agricultural combine for oscillation therewith for conveying chaff from the oscillating element to a non-oscillating chopper or spreader mounted to a fixed frame of the combine. The chaff pan is also sidewardly tiltable with the cleaning apparatus or system, if so capable.

Abstract: A foldable chaff pan for attachment to an oscillating element of a cleaning apparatus or system of an agricultural combine for oscillation therewith for conveying chaff from the oscillating element to a non-oscillating chopper or spreader mounted to a fixed frame of the combine. The chaff pan is also sidewardly tiltable with the cleaning apparatus or system, if so capable.

Abstract: A crop residue spreader for an agricultural combine including a unique support element which is an elongate tube, including a center portion and a pair of legs extending outwardly in opposite directions from the center portion, each of the legs including an end portion opposite the center portion and an intermediate portion. The end portions include pivot elements coaxially aligned about a pivotal axis for pivotal connection to a rear end of the combine for movement between spreading and non-spreading positions. The intermediate portions include mounting elements for supporting rotatable crop accelerators in side-by-side relation, and the center portion includes at least one mount for mounting a pair of crop residue deflectors in cantilever relation to the tube and extending partially around the crop residue accelerators, respectively. The tube can also include mounts or supports for holding a shield in desired relation to the crop residue accelerators.

Abstract: A drive system for the sieves in an agricultural combine that includes a flywheel for improving the fatigue life of the sieves. The flywheel minimizes damaging accelerations in the sieves that result from speed variations in the drive shaft. A hydraulic motor is also provided for directly driving the sieves without the use of belts.
