Abstract

A hybrid flute for a stalk roll may be configured with a sharp edge positioned between a first blunt edge and a second blunt edge along a length of the flute edge. The flute edge may extend radially outward from a main cylinder of the stalk roll. The flute edge may be engaged with a radius at the base of the flute edge, and a flute base may extend from the radius. A plurality of flute bases positioned adjacent to one another may be configured to form a main cylinder for the stalk roll. Wherein the main cylinder and one or more support members are formed of separable halves, the support members comprising inside planar surfaces for attachment to a square drive shaft.
