Abstract
A stalk roll comprises a cylindrical shell having six integral flutes. Each flute is provided with a knife edge having a leading surface and a trailing surface. The leading surface has a forward slope of approximately 10.degree. from the plane formed by the central longitudinal axis of the cylindrical shell and the vertex of the respective knife edge. The trailing surface has a reverse slope of approximately 30.degree. from the plane formed by the central longitudinal axis of the cylindrical shell and the vertex of the respective knife edge. The cylindrical shell comprises two semi-cylindrical pieces that are clamped about a drive shaft of a corn harvesting head by associated bolts.
