Реферат: 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~ 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~ 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.
