The rotating element feeds harvested crops to the separation unit from underneath the rotating element's axis of rotation. A transition housing connecting the feeder housing and the rotor housing has a plurality of interior edges forming a feeding opening through the transition housing wherein the interior edge of the transition housing that forms the bottom of the feeding opening is longer than the interior edge that forms the top of the feeding opening.
