ABSTRACT:
A land clearing apparatus that includes a rotating land clearing rasp used to shred trees, brush and debris. A conventional excavator can be used to provide a movable platform for carrying the rasp over the land to be cleared, and provides the motive power to drive the rasp. The rasp includes a rotating drum that has a plurality of cutters distributed on its outer surface, so that the cutters can be used to engage debris and vegetation when the drum is rotated. Each cutter includes a connector that connects the cutter to the drum. The connector includes joinder structure that is oriented to be primarily under compressive loads, not shear loads. In alternative embodiments of the invention, each cutter can have a plurality of indexable tips so that, as each tip wears, the cutter can be indexed to present a fresh tip. In addition, the connector between the cutter and the drum can be provided with a wear indicator to aid in determining when to replace the cutter, and the apparatus can include a pivot that allows the drum to be operated in a first position substantially perpendicular to the excavator, and a second position substantially parallel to the excavator.
