A stalk roll may be configured to be mounted upon a stalk roll drive shaft of a corn harvesting header, wherein the stalk roll drive shaft has a generally square cross-sectional shape. The stalk roll may comprise a main cylinder with a plurality of flutes extending radially from the main cylinder along the length of the main cylinder. A taper may be positioned toward the front end of the main cylinder. The flutes may be configured such that a bladeless area on each of two stalk rolls of an opposing pair cooperate to form at stalk engagement gap in at least one moment in time per revolution of the stalk rolls.

1. A stalk roll comprising: a. a main cylinder;b. a full flute engaged with said main cylinder and having a length along a longitudinal axis of said main cylinder, wherein said full flute extends outward from said main cylinder, wherein said full flute includes a sharp edge along a first portion of said full flute;c. a reduced flute engaged with said main cylinder adjacent said full flute and having a length along said longitudinal axis of said main cylinder, wherein said reduced flute extends outward from said main cylinder, wherein said reduced flute includes a sharp edge along a portion of said reduced flute, and wherein said length of said full flute is greater than said length of said reduced flute;d. a second reduced flute engaged with said main cylinder adjacent said reduced flute and having a length along said longitudinal axis of said main cylinder, wherein said second reduced flute extends outward from said main cylinder, wherein said second reduced flute includes a sharp edge along a portion of said second reduced flute, and wherein said length of said reduced flute is greater than said length of said second reduced flute;e. a third reduced flute engaged with said main cylinder adjacent said second reduced flute and having a length along said longitudinal axis of said main cylinder, wherein said third reduced flute extends outward from said main cylinder, wherein said third reduced flute includes a sharp edge along a portion of said third reduced flute, and wherein said length of said second reduced flute is greater than said length of said third reduced flute;f. a short flute engaged with said main cylinder adjacent said third reduced flute and having a length along said longitudinal axis of said main cylinder, wherein said short flute extends outward from said main cylinder, wherein said short flute includes a sharp edge along a portion of said short flute, and wherein said length of said third reduced flute is greater than said length of said short flute; andg. a support member positioned on an interior surface of said main cylinder, wherein said support member includes a first planar surface and a second planar surface that are oriented perpendicularly with respect to one another. 2. The stalk roll according to claim 1 further comprising a hybrid flute engaged with said main cylinder adjacent said full flute and having a length along said longitudinal axis of said main cylinder, wherein said hybrid flute extends outward from said main cylinder, wherein said hybrid flute includes a sharp edge along a first portion of said hybrid flute and a blunt edge along a second portion of said hybrid flute, and wherein said length of said hybrid flute is greater than said length of said full flute. 3. The stalk roll according to claim 2 wherein said hybrid flute further comprises a second blunt edge along a third portion of said hybrid flute, wherein said sharp edge is positioned between said blunt edge and said second blunt edge. 4. A stalk roll comprising: a. a first portion, wherein said first portion constitutes a first half of said stalk roll with respect to a plane bisecting said stalk roll about a rotational axis thereof, wherein said first portion comprises: i. a main cylinder;ii. a full flute engaged with said main cylinder and having a length along said rotational axis, wherein said full flute extends outward from said main cylinder, and wherein said full flute includes a sharp edge along a portion of said full flute;iii. a reduced flute engaged with said main cylinder adjacent said full flute and having a length along said rotational axis, wherein said reduced flute extends outward from said main cylinder, wherein said reduced flute includes a sharp edge along a portion of said reduced flute, and wherein said length of said full flute is greater than said length of said reduced flute;iv. a support member positioned on an interior surface of said main cylinder, wherein said support member includes a first planar surface and a second planar surface that are oriented perpendicularly with respect to one another, further including a third planar surface and a fourth planar surface that are oriented perpendicularly with respect to one another, wherein said third planar surface is parallel to and coplanar with said second planar surface, and wherein said first planar surface is parallel to said fourth planar surface;b. a second portion, wherein said second portion constitutes a second half of said stalk roll with respect to a plane bisecting said stalk roll about a rotational axis thereof, wherein said second portion comprises: i. a main cylinder;ii. a full flute engaged with said main cylinder and having a length along said rotational axis, wherein said full flute extends outward from said main cylinder, and wherein said full flute includes a sharp edge along a portion of said full flute;iii a reduced flute engaged with said main cylinder adjacent said full flute and having a length along said rotational axis, wherein said reduced flute extends outward from said main cylinder, wherein said reduced flute includes a sharp edge along a portion of said reduced flute, and wherein said length of said full flute is greater than said length of said reduced flute;iv. a support member positioned on an interior surface of said main cylinder, wherein said support member includes a first planar surface and a second planar surface that are oriented perpendicularly with respect to one another, further including a third planar surface and a fourth planar surface that are oriented perpendicularly with respect to one another, wherein said third planar surface is parallel to and coplanar with said second planar surface, wherein said first planar surface is parallel to said fourth planar surface, wherein said fourth planar surface of said first portion and said fourth planar surface of said second portion are coplanar when said first portion is aligned with said second portion for use on a stalk roll drive shaft, and wherein said first planar surface of said first portion and said first planar surface of said second portion are coplanar when said first portion is aligned with said second portion for use on said stalk roll drive shaft. 5. The stalk roll according to claim 4 wherein said support member on said first portion further comprises an aperture and an anchor, and wherein said support member on said second portion further comprises an aperture and an anchor. 6. The stalk roll according to claim 5 wherein said aperture in said first portion aligned with said anchor in said second portion and said aperture in said second portion aligned with said anchor in said first portion when said first portion is engaged with said second portion about a stalk roll drive shaft. 7.
