A rotor for a threshing system of an agricultural combine, the rotor having a sequence of four inlet impellers disposed around an inlet section thereof at predetermined angularly spaced positions around a rotational axis therethrough, the impellers being oriented and configured for conveying crop material along generally helical flow paths, respectively, about the inlet section to a threshing section of the rotor when rotated and the crop material is fed thereto, and three rasp bars configured for threshing the crop material disposed in axially offset relation in a row extending circumferentially about the threshing section, including a first rasp bar at a first axial position adjacent to an end of the second inlet impeller of the sequence, a second rasp bar at a second axial position adjacent to an end of the third impeller of the sequence, and a third rasp bar at a third axial position and axially spaced from the first impeller of the sequence defining a crop material flow path therebetween.
