Abstract
A rotor assembly for a rotary combine having an anti-wrap blade assembly which acts in combination with an impeller blade assembly to direct material outwardly and rearwardly relative to the longitudinal axis of the rotor assembly. The anti-wrap blade assembly includes a plurality of flights arranged at a foremost end of the rotor assembly in equally spaced relation about the rotational axis of the rotor assembly. Each blade of the anti-wrap assembly has a leading edge lying in a plane extending generally normal to the rotational axis and includes a material engaging surface which has a generally concave shape configuration extending rearwardly from the leading edge of the blade for directing materials outwardly and rearwardly from the rotational axis of the rotor. The rotor assembly further includes an anti-wind assembly for inhibiting debris and other foreign matter from contaminating a bearing assembly which rotatably mounts one end of the rotor assembly.
