Abstract

The rotary beater has a number of untwisted, flat, feeding plate segments angularly disposed about its periphery. The plates are arranged in a left-hand group and a right-hand group so oriented that they converge the crop material centrally as they feed and accelerate the crop material rearwardly toward and through the inlet of an axial flow threshing rotor assembly. The feeding segments of each group are arranged in diametrically opposed sets containing at least one segment each, and the sets of one group are offset circumferentially 90° from the sets of the other group. Each segment has a hardened crop-engaging face, and the segments are all detachably bolted to the drum of the beater to facilitate removal and replacement when worn or damaged.
