ABSTRACT:
An agricultural combine having a pair of side-by-side axial separators. Each of the axial separators comprises a cylindrical tube, a rotor housed in the tube, an inlet and an outlet. An axial air stream is directed along the top of the axial separator to remove dust, chaff and other debris that may accumulate there. The air stream is intercepted from the cooling fan of an internal combustion engine by duct work that directs the air stream to a deflector located above the axial separators. The deflector forms a forward axial air stream component and a rearward axial air stream component. Exhaust openings are formed in the sidewalls of the combine to vent the forward air stream component. An exhaust gap is formed at the rear of the axial separator to vent the rearward air stream component.
