ABSTRACT:
A self-propelled combine has a forwardly extending, vertically adjustable crop-feeding housing and a transversely elongated, cutter bar type harvesting platform mounted on the forward end of the housing. The platform includes a transversely elongated frame with a transverse flexible cutter bar disposed along the leading edge of the platform floor. The cutter bar is mounted on the platform by a plurality of transversely spaced parallel type linkages that permit independent vertical adjustment of different areas of the cutter bar so that the cutter bar is free to follow the contour of the ground. A wobble type drive mechanism is mounted on one end of the cutter bar and floats therewith, and a sheet-like spring member spans the width of the platform and has its rearward end attached to the platform floor and its forward end connected to the cutter bar, the spring member deflecting downwardly as the cutter bar swings downwardly to partially counterbalance the weight of the cutter bar, the spring member also sealing the area between the floor and the cutter bar. Structure is also provided for adjusting the cutter bar in a fore and aft direction relative to the floor to vary the distance between the cutter bar and the platform auger.
