ABSTRACT:
An oscillating knife cutting apparatus preferably for use on a row crop harvesting unit of a forage harvester to sever crop material from its standing position in a field as it is delivered into the harvester. The apparatus comprises a main support with a main pair of knives fixed thereon, a bearing fixed to said main support, a shaft rotatably mounted in said bearing, and a secondary support with a knife fixed thereto. The secondary support is mounted on said shaft for oscillatory movement therewith relative to said main support. The secondary knife is disposed between the pair of main knives and is used to sever material disposed between the secondary knife and each of the main knives. The secondary knife is adjustably mounted for movement toward the plane defined by the main knives by adjustment of a member threadably mounted longitudinally of the shaft whereby rotation of the threaded member frictionally engages a clamp mounting the secondary support on the shaft. Also to compensate for uneven wear of the knives, one end of the secondary knife is bendable toward the plane defined by the main knives through rotation of a screw threadably mounted in the secondary support.
