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.
