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.

Abstract: A stalk roll for an agricultural harvester row unit comprising a plurality of longitudinal extending knife edges about its circumference, in which one of the leading and trailing sides of the knife edges is coated with a first wear resistant coating over substantially its entire length, and in which the other of the leading and trailing sides is coated with a second wear resistant coating over at least one of a front portion thereof and a rear portion thereof.

Abstract: An apparatus for reducing and separating an associated agricultural product into two or more sub-parts is provided. A first housing includes an inlet and an outlet, the inlet being configured to receive the associated agricultural product to be reduced. A first reducing assembly is disposed between and in communication with the inlet and the outlet of the first housing and includes a first rotatable reducing member, a second rotatable reducing member, and a reaction member. The first reducing member, the second reducing member and the reaction member are disposed adjacent to the other and cooperate to receive and reduce the associated agricultural product to a plurality of first sub-parts. A second housing includes an inlet and an outlet, the inlet being configured to receive select ones of the plurality of first sub-parts. A second reducing assembly is disposed between the inlet and the outlet of the second housing and includes a reducing rotor and a stationary reducing ring.
