Abstract
A knife for a cylindrical rotor includes at least two sharpened edges adapted to cut materials during land clearing or mulching. The knife further includes a top surface and a bottom surface wherein the knife is shaped as an inverted frusto-square pyramid. The knife may further include a tapered sidewall defining one sharpened edge. The angle may be about 30° to about 60°. The knife may have four sharpened edges. The knife further may include an aperture that may be equidistant from the four sharpened edges. The knife is adapted to be moved when one sharpened edge becomes dull. The knife may further include a conical countersunk aperture. The knife may have a thickness of about ¼″ to about ½″.
Claims20
A knife for a cylindrical rotor that is to be powered by a drivable device, the knife adapted to be coupled to an exterior surface of the cylindrical rotor to chip, chop, cut, or mulch material contacted by the knife in response to rotation of the cylindrical rotor, the knife comprising:
- at least two sharpened edges, wherein one of the at least two sharpened edges chips, chops, cuts, or mulches material in response to rotation of the cylindrical rotor during land clearing or mulching;
- a top surface spaced from a bottom surface, wherein the knife is shaped generally as an inverted frusto-square pyramid;
- a tapered sidewall defining one sharpened edge, wherein the tapered sidewall extends between the top surface and the bottom surface at an angle;
- an aperture defined from the top surface to the bottom surface adapted to align with a hole formed in the cylindrical rotor;
- and
- wherein the knife is adapted to be moved to change a leading cutting edge of the knife when the one sharpened edge becomes dull.
