  • Patent number: 4011709
    Abstract: A self-propelled combine has a forwardly extending, vertically adjustable crop feeder housing and a transversely elongated, cutter bar type harvesting platform mounted on the forward end of the housing. The platform includes a floor and a transverse auger that extends the width of the platform and converges the crop along the floor to the center of the platform, for discharge rearwardly to the feeder housing. A cutter bar spans the width of the platform along the leading edge of the floor and is mounted for fore and aft extension or retraction into different fore and aft positions to vary the distance between the cutter bar and the auger. Members are also provided for adjusting the tilt of the cutter bar about a transverse horizontal axis, so that the cutter bar skids, which ride along the ground, can be adjusted to the desired angle relative to the ground.

  • Patent number: 3938683
    Abstract: A self-propelled combine has an elevated grain tank and a clean grain elevator extending upwardly along one side of the combine body and having an upper discharge end below the level of the top of the grain tank. The upper discharge end of the elevator dumps into a chamber that is disposed adjacent to one side of the grain tank, and a laterally extending auger type conveyor is inclined upwardly and inwardly in cantilever fashion from the chamber for moving grain from the chamber to the discharge end of the auger type conveyor, which is above a central portion of the grain tank. The lower end of the conveyor auger extends through the outer wall of the chamber and a bevel type gear case is mounted on the wall of the chamber, the gear case having an upwardly and inwardly inclined output shaft connected to the auger and a horizontal input shaft that is driven by belt drive on the side of the combine.
