ABSTRACT:
A pair of elongated, generally transversely triangular deflector members are attachable to opposite, upstanding sidewalls of the foraminous, platform-like cleaning shoe of a combine for the purpose of preventing disproportionate accumulation and build-up of crop materials on the downhill side of the cleaning shoe when the combine is performing harvesting operations on sidehill slopes. The deflector members are fixed to such sidewalls for reciprocation with the shoe during agitation thereof and are provided with upwardly and inwardly extending baffle surfaces having the ability to redirect crop materials and air currents back toward the central portion of the shoe to counteract the effective gravity tending to cause the disproportionate accumulation of materials against the downhill sidewall. Through the inclined baffle surfaces and oppositely inclined feeder plates on downwardly and inwardly inclined surfaces of the members, the materials tend to be spread more evenly over the entire surface area of the shoe than would otherwise be the case in sidehill slope situations, to the end that grain loss is reduced and cleaning efficiency is increased.
