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.

Oscillating knife cutting apparatus

An upper stalk guide or control for a forage harvester header. The stalk control comprises a transverse member spaced above the crop conveying passageways of the header, two outwardly and forwardly diverging arms attached to the respective ends of the transverse member and a centrally disposed wedge member for subdividing the upper portions of the crop stalks so as to enhance the clog-free feeding of the butt ends of the stalk through the crop receiving passageways of the header and into the throat of the harvester in advance of the upper portions.

Forage harvester header with upper stalk control

A multirow forage harvester header for cutting and conveying a row crop from a standing position in the field into a crop receiving throat of the harvester for processing. The header is provided with an improved drive means for actuating a pair of crop cutters respectively disposed adjacent the crop entries of two crop receiving and conveying passageways of the header. The drive means includes a reciprocatable rod connected between one of the cutters and a remotely located input drive and a second reciprocatable rod connected between the two cutters. The two cutters are synchronously driven by the input drive through the first and second reciprocating rods.
