Abstract: A mower conditioner includes a cutter bar supported on its frame transverse to the forward working direction and conditioning tools, which may be either tines or conditioning rollers, supported on the frame to span a distance transverse to the forward working direction. Auger flights are supported on the frame beyond opposite ends of the distance traversing the forward working direction for rotation about respective axes also traversing the forward direction, the auger flights beyond one end of the distance spanned by the conditioning tools being pitched in a direction opposite the auger flights on the opposite end of the distance spanned by the conditioning tools to convey cut crop material toward the conditioning tools. The auger flights are driven in a direction upward and forward from a lowermost point on their rotational path and are positioned over the cutter bar to effect clearing of the cut crop material therefrom.
