Abstract
In a crop harvesting and threshing machine of the type utilizing axial flow threshing and separation there is provided about the upper portions of the rotor casing axial flow inhibiting elements rearwardly of axial flow facilitating elements. The inhibiting elements are arranged in a reverse pattern to the facilitating elements so that crop material transported axially about the threshing and separating rotors is decelerated and deflected into a discharge opening without passing further rearwardly, thus preventing the enwrapping of crop material about the rotatable shafts of the rotor.
