Abstract
A threshing assembly is provided for a combine having a frame mounted on wheels and a longitudinal axis. The threshing assembly is formed from a threshing rotor disposed within a perforated threshing cage. At least one helical vane, formed of high strength plastic, mounts to the interior of the threshing cage and extends along the length of the threshing cage. The radial height of the vane is graduated along the length of the threshing cage from the forward end to the rearward end for threshing of different size grain crop. Rasp bars of the threshing rotor also have heights that increase along the length of the threshing rotor, from the forward end to the rearward end, to correspond to the decrease in height of the vanes.
