Abstract

A rotor for an axial flow combine which is adapted to coact with conventional grate means in said combine, said rotor having on the forward end thereof interrupted infeed flight means which are spiral segments spaced both axially and circumferentially from each other, and certain of the leading ends of said flight segments in the direction of rotation of the rotor extending radially a limited distance beyond the outer edges of said segments to provide aggressive engagement of said segments with crop material being delivered to said flight from conventional elevator mechanism and the like normally employed in combines.
