ABSTRACT:
A cleaning apparatus for a combine harvester is disclosed wherein the grain pan and chaffer sieve are mounted for pivotal leveling movement about both a transversely extending axis and a longitudinally extending axis. The grain pan and chaffer sieve are mounted in a subframe pivotally supported by a shaker shoe such that the subframe is pivotable about a longitudinally extending axis relative to the shaker shoe, which in turn is pivotally supported on the combine main frame for pivotal movement about a transversely extending axis. A pair of inclinometers disposed to sense the inclination of the combine are utilized to control the flow of hydraulic fluid to hydraulic actuators arranged to pivotally move the shaker shoe and the subframe in response to a sensing of a non-horizontal inclination by the inclinometers. A combination of the fore-and-aft and transverse pivotal movements permits the grain pan and chaffer sieve to be maintained in an overall horizontal orientation irrespective of the attitude of the combine main frame.
