First and second stripper plates for a harvesting header that are offset from one another relative the ground. The first and second stripper plates oppose one another to at least partially define a first crop passage for receiving crop stalks and to remove useable parts from the crop stalks gathered in the crop passage. In one embodiment, the first and second stripper plates are offset from one another relative the ground to urge the crop stalks laterally toward a gathering auger of a row unit of the header.
