ABSTRACT:
A forage harvester row crop header having a mobile frame, at least one fore-and-aft extending row crop unit mounted on the frame and including an elongated passageway for receiving a row of crop as the header advances forwardly over a field of crop planted in spaced apart rows is provided with an improved severing mechanism for severing the crop within the passageway and which further insures the severance of grass-like materials within the crop row. The improved severing mechanism includes upper and lower rotary severing discs and a lower rotary guide disc. The upper and lower rotary severing discs are disposed on opposite sides of the elongated passageway and overlap within the passageway in defining a severing zone for severance of crop material. The lower rotary guide disc is mounted to and below the upper severing disc. Upon operation, the guide disc engages grass-like materials within the row crop and orients the same into the severing zone resulting in severance thereof. The improved severing mechanism further includes stripper bars so positioned so as to maintain the severing mechanism free from any build-up of crop material within the severing mechanism which would adversely affect its operation.
