ABSTRACT:
An axial flow combine with a transverse rotor (18) employs a combined impeller and chopper (66) having knives which strip crop material from a rotor discharge paddle impeller (34), chop it in cooperation with selectively retractible blades (96) and throw it rearwardly through a discharge passageway (56) to a downwardly opening discharge (57). The chopper (66) may be driven at either one of two speeds and eliminates the need for the usual impeller employed to move crop material from the threshing rotor discharge impeller (34) to the rear discharge (57) of the combine.
