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.
