Abstract: A device for husking corn ears is disclosed. The device removes the husks and silks and at the same time avoids substantial damage to the kernels. The device includes a plurality of rollers and drive means which rotate the rollers at selected speeds in selected directions in a selected sequence. A method of husking corn comprising the steps of cutting the butt end off the ear, and positioning the ear between closely spaced rollers rotating in opposite directions to gently remove the husks is also disclosed.

Abstract: A concave includes a frame and an array of threshing elements supported by the frame, the threshing elements being spaced apart and extending generally parallel to one another. The threshing elements are configured in the form of round bars each having formed on an upper portion thereof disposed adjacent to an upper portion of the frame a longitudinally-extending notch respectively defining an aggressive threshing edge. The spaced apart relationship and round configuration of the threshing elements reduce plugging of the concave. The threshing edges facing in a direction opposite to the direction of crop material flow restrict crop material flow and thereby enable more effective threshing.
