Abstract
A rotor assembly for an agricultural combine includes a rotor, a plurality of short thresher elements and a plurality of elongated thresher elements. The short thresher elements and a plurality of elongated thresher elements are arranged on the rotor so that the crop material contacts at least two short thresher elements before contacting an elongated element, thereby breaking up clumps of crop material before the clumps contact an elongated element. The agricultural combine has a rotor having a front portion, a rear portion a plurality of elongated thresher elements. Each elongated thresher element is aligned along a separate longitudinal line which extends from the front portion to the rear portion, to prevent a roll of material from building across multiple elongated thresher elements.
