Abstract
A combine harvester is disclosed in which the threshing and separating means includes a rotor, a concave extending at least partially around the rotor at a location above the axis of rotation of the rotor, and sweepers disposed in the vicinity of the concave and operable to sweep crop material passing through the concave means away from the latter so as to prevent any excessive build up of crop material on the concave.
