Abstract
A mechanism for selectively adjusting the cutting angle of a combine header relative to the ground is disclosed wherein a front face member is pivotably mounted to the forward end of the feeder house for rotation about the forward transverse axis of the crop conveyor within the feeder house. Structure is provided to adjustably lock the front face member into one of a plurality of alternative rotated positions. With the disclosed mechanism, the header cutting angle can be adjusted relative to the ground without increasing the distance between the header and the crop conveyor, thereby maintaining the efficiency of the crop conveyor to engage crop material and transport it rearwardly.
