ABSTRACT:
A header frame for a combine includes a mounting frame which is attached to the front end of the feeder housing of the combine and a header frame. The header frame is mounted on the mounting frame by suitable linkage so that it can lift in a vertical direction and also can twist about an axis parallel to the forward direction of the combine to allow the header frame to follow ground contours. A flexible pan is connected between the header frame and the mounting frame to define a lower surface of the header immediately in front of the mouth of the feeder housing with the pan having a forward edge attached to the header frame and a rearward edge attached to the mounting frame with the movement therebetween being accommodated by flexing or sliding of one mounting of the pan. In one arrangement of the header, the conventional auger is replaced by two side drapers and a feed draper with the feed draper being mounted in a manner which allows limited vertical movement away from the pan.
