- 1 - ABSTRACT OF THE DISCLOSURE A combine is described including a longitudinally extending auger which is mounted in a tubular casing. The auger is provided with spiral flighting for conveying cut crop material rearwardly between the exterior surface of the auger and the interior surface of the tubular casing. A longitudinally extending threshing cylinder is mounted on the rearward end of the auger for rotation therewith. The cylinder has a flared configuration with its rearward end having a larger diameter than its forward end. A longitudinally extending concave embraces the cylinder and is longi- tudinally adjustably movably mounted with respect to the cylinder. The concave also has a flared configura- tion so that its rearward end has a larger diameter than its forward end and is spaced from the cylinder to define a threshing space therebetween. The forward end of the concave is in communication with the rearward end of the auger so that cut crop material will be delivered to the forward portion of the threshing space. The means for longitudinally adjustably moving the con- cave with respect to the cylinder comprises a power cylinder apparatus.
