Stalk roll
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.

4. The hub assembly ( 470 ) of claim 2 wherein the diameter of the recess ( 420 ) varies along the length.
5. A stalk roll ( 400 ) comprising:
a plurality of flutes ( 440 , 440 a , 460 ), wherein:
each flute ( 440 , 440 a , 460 ) has a flute base ( 449 ) and a flute edge ( 442 ),
said flute base ( 449 ) and said flute edge ( 442 ) are connected to one another via a radius ( 443 ),
a length of said flute base ( 449 ) is parallel to a length of said flute edge ( 442 ),
a width of said flute base ( 449 ) is angled with respect to a width of said flute edge ( 442 ),
a main cylinder ( 430 ) formed from positioning each flute base ( 449 ) of the plurality of flutes ( 440 , 440 a , 460 ) adjacent one another, said plurality of flutes ( 440 , 440 a , 450 , 450 a , 460 ) including two separate groups, wherein each of the groups covers approximately half of an overall surface area of the main cylinder ( 430 ) of the main cylinder ( 430 ),
a nose cone ( 410 ) engaged with said plurality of flutes ( 440 , 440 a , 460 ) at a terminal end of said plurality of flutes,
a recess ( 420 ) formed in the nose cone ( 410 ) between a front end of the main cylinder ( 430 ) and the nose cone ( 410 ); and
wherein said flute edges ( 442 ) extend outward from said main cylinder ( 430 ) in a generally radial direction.
6. The stalk roll ( 400 ) according to claim 5 wherein said flute edge ( 442 ) of at least one of the plurality of flutes ( 440 , 440 a , 460 ) further comprises a first blunt edge ( 442 b ) and a first sharp edge ( 442 a ) along said length of said flute edge ( 442 ).
7. The stalk roll ( 400 ) according to claim 6 wherein said flute base ( 449 ) further comprises an aperture ( 449 a ) passing through said base ( 449 ).
8. The stalk roll ( 400 ) according to claim 7 wherein said flute base ( 449 ) further comprises a base bevel ( 449 b ) at the terminal end of said base ( 449 ), wherein said terminal end is adjacent a second blunt edge ( 442 b ) of said flute edge ( 442 ).
9. The stalk roll ( 400 ) according to claim 5 wherein said flute base ( 449 ) further comprises a notch ( 462 ) formed in said base ( 449 ) along a length of said base, wherein said notch ( 462 ) reduces the distance between an edge of said base ( 449 ) and said radius ( 443 ).
