A SHEARING STALK ROLL SET AND METHOD OF HARVESTING CORN

摘要

A stalk roll set (16) for a corn-harvesting combine (10) includes first and second rolls (20 and 22), respectively, adjacent one another, each having an axis of rotation and defining a shear zone (42) therebetween. At least one pair of flutes (30, 36) projects radially from each roll (20 and 22). The pair of flutes (30, 36) are bilaterally symmetrical and each includes a knife edge (26) with a leading surface (32) and a trailing surface (34) forming an acute angle therebetween, whereby the flutes (30, 36) of the adjoining stalk rolls (20 and 22) are offset to and overlapping one another.
