ABSTRACT:
An agricultural combine has a generally horizontal grain pan for delivering threshed crop material to a grain cleaning mechanism. The grain pan includes a plurality of generally upright fore-and-aft extending vanes that are adjustable to deflect crop material toward either lateral side of the grain pan to compensate for the gravity influenced migration of grain toward the downhill side of the combine when operating on a side slope. The vanes are automatically controlled by an electrical system that includes sensors at opposite sides of the grain pan that detect the building of crop material on the downhill side of the combine and adjusts the vanes to compensate for the buildup.
