Abstract
The use of a baffle (61) spaces the horizontal cleaning air discharge a substantial distance below the accelerator rolls (32, 33) to substantially reduce passage of cleaning air to the threshing area (18). This in turn reduces the amount of dirty air discharged from the forward end of the combine in the area of the operator's cab (26).
