ABSTRACT:
A rotatable forage harvester cutterhead having a rotatable shaft, and a plurality of axially spaced disc shaped plate members having substantially the same diameters and affixed in parallel planes transversely along the shaft for rotation therewith. A plurality of mounting members are detachably secured to the plate members for mounting a drum having an inner surface having a diameter at least as great as the diameters of the disc shaped plate members. Attachment means are employed for detachably securing the drum to the mounting members. Each of a plurality of substantially flat knives with a cutting edge extending in a transverse direction less than half the axial length of the drum are mounted on knife support assemblies comprising support blocks. The attachment means for securing the drum to the discs also secures the knife support blocks to the outer surface of the drum. Fasteners secure the knives to the blocks with the cutting edges extending in the direction of rotation of the cutterhead and generating a cylinder, under conditions where the cutterhead rotates, having a diameter larger than the diameter of the drum.
