Abstract: In a pull type forage harvester which travels forwardly in a field to pick up crop material and feed it into a housing having a cutterhead with knives rotatable around a transverse axes. The cutterhead chops the crop material and deposits it in a transverse trough having an auger which carries the crop to a lateral discharge location. The improvement comprises a corn processor adapter to which chopped corn is conveyed over a floor to an upper and a lower roll rotatable on axes parallel to the cutterhead. The rolls form a bite to receive the corn and pass it between them to crush the kernels therein. The upper roll is positioned close to the cutterhead knives and in crop stripping relation thereto. The lower roll is positioned over the auger to hold down chopped corn thrown upwardly out of the trough.

The dispensing tube is adapted to be driven along its predetermined path either manually by a handle having a gear segment that driveably mates with the gear segmented plate or automatically by a hydraulic cylinder that is operably connected to the shaft that rotatably supports the plate and the tube.

Abstract: An improved paddle design for use on the beater mechanism of a manure spreader enables the spreader to satisfactoriloy handle a broader range of manure consistencies and to distribute the same over a more uniform and wide spread pattern. The paddle has a dished or cupped shape, is substantially symmetrical about its centerline, and includes a curved main body portion and integrally formed upper engaging and lower mounting portions. The upper portion has a curved shape similar to the main body portion and is inclined inwardly toward the axis of curvature of the main body portion, thus providing a concave working surface. The lower portion presents a planar surface for mounting the paddle on a beater shaft. The paddle, being symmetrical, can be used on either the left or right sides of a spreader.
