Abstract
A cleaning apparatus for a combine harvester is disclosed wherein the grain pan and sieves are mounted in a shaker shoe pivotally supported on the main frame of the combine for movement about a transversely extending axis. Hydraulic actuators interconnecting the main frame and the shaker shoe affect a pivotal movement of the shaker shoe to level the cleaning apparatus under conditions where the combine has an inclined fore-and-aft orientation. An inclinometer is utilized to control the flow of hydraulic fluid to the hydraulic actuators to permit the shaker shoe to be leveled in response to a sensing of a non-horizontal fore-and-aft inclination by the inclinometer.
