ABSTRACT:
A cleaning system for a combine having a plurality of cleaning sieves which are operated to arrange grain in a thin veil or crop mat on the sieves. The cleaning system of the present invention includes an elongated transverse cleaning fan and an air plenum. The cleaning fan is rotatably driven about a fixed axis and includes a plurality of spaced apart blades peripherally disposed about the fan. The air plenum extends parallel to and along substantially the entire length of the fan for directing a forced flow of air from the fan rearwardly through the cleaning sieves. The air plenum includes upper and lower air directing baffles.
