Abstract: A corn snapping header for a forage harvester is provided with corn snapping units of the snapping plate type which are disposed with their crop passages converging to a single rear outlet. A single transverse drive line with flexible drive means is provided to drive the snapping units.

Abstract: A forage harvester including an imperforate peripheral shield for the cutterhead extending from the shear bar in the direction of rotation and a plurality of parallel elongated bars mounted on the face of the shield adjacent the cutterhead periphery and disposed at an obtuse angle to the direction of rotation, preferably greater than the obtuse angle of the cutterhead knives to the direction of rotation.

Abstract: A corn snapping header frame having transverse beam assemblies pivotally mounted at each end of a transverse main frame, the transverse beams being forwardly offset from the frame and having corn snapping units mounted thereon.

Abstract: A self-cleaning sprocket, especially for use with an endless belt having internal drive lugs in a crop gathering unit, being a body of material having a disk-like base portion and a plurality of radial ribs extending axially from the base portion and converging to a central hub portion, the ribs and base center portion defining a plurality of open-ended lug-receiving pockets. The portion of the base portion in the pockets slopes axially toward the open end from the periphery to the hub portion and the hub portion slopes radially inwardly from the base portion to the open end, the intersection of the hub and base portions being filletted to promote the flow of debris from the base portion to the hub portion. The axial end of the sprocket is preferably flat and without obstructions and extends beyond the lateral edge of the belt. The sprocket is preferably mounted with the pockets in a generally upright position from its opposite axial end whereat a second plurality of pockets are formed.
