Title: Rotor for a combine

Abstract: A rotor for an axial flow type combine has a generally cylindrical main body portion with a pair of rasp bars mounted longitudinally thereon. The forward portion of each of the rasp bars is inclined outwardly and rearwardly to provide an infeed spacing between the forward portion of the rotor and associated concave which will accommodate abnormal masses of crop material and function to thin out these masses prior to further axial movement of the crop material rearwardly into the threshing and separating region of the rotor.
