ABSTRACT:
The cutter box which houses a cutting cylinder on a harvester has an access opening in its top wall through which an abrasive, full-length sharpening stone may be alternately inserted and removed to engage and sharpen the peripherally located knives of the cylinder as the latter is rotated. Each time the stone is rocked down into the opening for a sharpening operation, it is indexed slightly further into the opening than during the previous operation in order to accommodate the slightly reduced diameter of the cylinder due to material which has been removed from the knives and the stone during the previous sharpening operation. A cover coupled with the stone is caused to move into closing relationship with the opening as the stone is rocked out of the same and, conversely, to pull away from and expose the opening as the stone is subsequently reinserted. All of the mechanical movements involved, including indexing of the stone, may be accomplished remotely through the use of an electric motor.
