Abstract
A combine harvester comprising two side-by-side generally cylindrical crop handling units each having tandem threshing and separating sections. A conveyor is provided for receiving crop material from a forwardly positioned crop header and delivering it axially into the cylindrical units. During operation, grain is separated from the crop material and discharged through concaves and grates in the threshing and separating sections, respectively, onto a grain pan which in turn deposits it on cleaning sieves located rearwardly of the grain pan. The clean grain is elevated by an auger to a storage tank mounted on the combine while the residue is conveyed rearwardly and expelled onto the field. At least a portion of the grates in the separating sections are cylindrical in configuration and permit discharge over most or all of the circumference of the cylindrical units.
