A crop residue spreader for a combine harvester is pivotally mounted to the combine for rotation about a transverse axis. The spreader has a spreading position in which crop residue is spread over a wide area at the rear of the combine. The spreader is rotatable about the transverse axis to a raised windrowing position to allow the residue to fall to the ground in a windrow for later collection. The disks of the spreader are covered by shrouds above and to the sides to reduce the upward dispersal of the residue. Gas assist cylinders are provided to lift the spreader to the windrow position after which a latch is engaged to hold the spreader there. A hold down latch operates to hold the spreader in the spreading position in opposition to the gas assist cylinders.

[ What is claimed is:] [1.]1. A spreader for a combine harvester having a structure and adapted to move over a field to gather and process an agricultural crop having straw which, after processing, is discharged from a separator as crop residue, the spreader comprising:a pair of rotating disks each having one or more radial ridges, the disks being rotatably carried by a frame at the rear of the combine to receive and disperse the crop residue;the frame being pivotally mounted to the combine structure for rotation about a transverse axis to move the disks between a generally horizontal spreading position and a raised windrowing position in which the crop residue is permitted to drop downward from the combine to the ground without being dispersed by the spreader;a top shroud spaced above a rear portion of the disks to reduce upward dispersal of the crop residue, top shroud being carried by the frame for pivotal movement therewith; andside shrouds extending laterally from the top shroud outward beyond the combine structure and carried by the frame for pivotal movement therewith.
