Abstract
A shredding apparatus utilizes a cylindrical drum adapted for quickly and effectively clearing large tracts of land. Several blocks are positioned in two spiral rows on the periphery of the drum and are secured to the drum by welding. The blocks in each row are spaced from one another an axial distance that provides a complete sweep of the land as the drum rotates. Each of the blocks includes a replaceable cutter tooth. The teeth each include a shank that is anchored in a hole in each block. At least one block is mounted along each edge of the drum at a slight outward angle between about 2°, and about 15°, and is tilted outwardly between about 2° and about 5° so that its corresponding tooth provides protection of the drum edge. All of the remaining blocks are mounted so that the teeth are parallel with the drum axis.
