Abstract
A method for a cylindrical device includes semi-helically oriented teeth, knives, or blades radially outward from an outer surface of the cylindrical device or rotor is provided. Each tooth, knife, or blade is part of a row of teeth, knives, or blades. Each row is oriented with an offset angle such that the spirally orientation completes angular offset of about 90° or less. The knives may have sharpened edges that are oriented to cut on different planes as the cylindrical device rotates. The knives may be held in place by holders that have configurations to oriented the knives at certain angles.

A method comprising:
- rotating a rotor of a land clearing attachment about a transverse axis, wherein the rotor includes a first row of knives on an outer surface of the rotor, wherein at least one knife in the first row of knives includes a first sharpened edge and a second sharpened edge, wherein the first sharpened edge is initially a leading edge of the at least one knife that is adapted to cut in-ground material;
- cutting the in-ground material with the first sharpened edge to clear, chip or mulch the in-ground material;
- dulling the first sharpened edge in response to cutting the in-ground material;
- rotating the at least one knife after the first sharpened edge has dulled to position the second sharpened edge as a new leading edge of the at least one knife;
- and
- cutting the in-ground material with the second sharpened edge to clear, chip or mulch the material.
