Abstract
A mobile combine having longitudinally extending rotor and concave threshing members and a reciprocating grain pan beneath said concave to receive threshed and partially threshed crop products for passage to sieve mechanism, and angular deflector members fixed to and reciprocable with said grain pan and extending longitudinally therewith, said members extending downward and inward from opposite sides of the chamber below said concave and above said grain pan to deflect grain falling from said concave and direct it toward the center of said grain pan to prevent crop material from gravitating more to one side of said grain pan than the other such as during hillside harvesting operations.
