Abstract
A harvesting machine with crop threshing and separating means; the crop threshing and separating means comprising a separator rotor rotatably mounted in a generally cylindrical separator housing and operable to move crop material across the inside of said housing. The separator housing is formed in part by a separator concave for the separation of grain therethrough, and in part by an impervious cover rearwardly of the separator concave as seen in the direction of rotation of the separator rotor. The concave and the impervious cover have adjacent edges which are spaced apart over a short distance, thus defining an opening therebetween and downstream of the separator concave.
