Abstract
A rotor tine construction for a rotary element of a crop residue treatment system for effecting improved transport of crop residue along a material flow path and, if a counter knife assembly is spaced from the rotary element across the material flow path, for also effecting improved shear cutting of such crop residue by the knife elements of the counter knife assembly and more efficient operation of the crop residue treatment system, which rotor tine construction includes a base portion generally mountable to the rotary member of the rotary element, at least one rotor tine extending outwardly from such base portion and including three distinct blade edges, one of which forms a trailing edge and the other two of which are upper and lower edge portions forming a leading edge, with the lower and upper edge portions configured and intersecting with one another to form a notch-like indentation along the leading edge at an intersection point P defined to be the point of cut contact position, such that, as the rotary member rotates forwardly the rotor tine is rotated through the material flow path to engage and concentrate engaged lengths of crop residue near intersection point P for an i…
