Abstract
A forage harvester includes front and rear sets of upper and lower feed rolls that cooperate to convey a mat of crop material across a shear bar with which a cutterhead cooperates to cut the crop into short lengths. The front set of feed rolls and the upper feed roll of the rear set are contained in a feed roll housing including a movable frame section that is horizontally pivotally mounted to a fixed frame section, containing the cutterhead, shear bar and lower feed roll of the rear set of feed rolls, for movement between a normal working position and service position permitting easy access to the shear bar.
