Abstract
A crop handling unit for an axial-flow type combine harvester having an infeed region and tandem threshing and separating regions. An associated conveyor is provided for delivering crop material into the infeed region of the unit whereupon material is urged rearwardly along a generally helical path. Ultimately grain is separated from the crop material and discharged through concaves and grates in the threshing and separating regions, respectively, onto a grain pan. The infeed region is provided with improved means to spread out abnormally thick masses of material during its rearward travel.
