Abstract
The rear mounted straw chopper of a combine harvester receives the straw discharge from the straw walkers of the combine and discharges chopped straw rearwardly. The chopper is slidably supported on a pair of spaced apart, longitudinally oriented guide rails so that the chopper can be adjusted from a rearward, operating position to a forward, inoperative or windrow position in which straw bypasses the chopper. Movement of the chopper on its guide rails is facilitated by attachment to the straw chopper casing of a transverse shaft and sprocket assembly, the teeth of a pair of sprockets engaging longitudinally spaced openings in the guide rails so that, upon rotation of the shaft, the sprockets and guide rails cooperate in rack and pinion fashion to propel the chopper assembly along the rails while maintaining it in square alignment. The shaft and sprocket assembly may be rotated conveniently by means of a wrench engaging flats on an end of the shaft.
