Abstract
A cutting tooth having a blade-like cutting section and a mounting section extending down from the bottom of the cutting section. The mounting section is narrower and shorter than the cutting section, and generally centered with respect to the cutting section. The mounting section has laterally extending flanges spaced from the cutting section. At least a quarter of the cutting section extends past the front of the mounting section and terminating in a cutting edge.The cutting tooth is adapted to be mounted in a mounting block to form a cutting assembly. The mounting block has a slot extending into the block from the front face, the slot open in the top surface of the block. The mounting section of the tooth slides into the slot in the block to locate the cutting section on the top of the block with the cutting section projecting forwardly of the block. The flanges on the tooth hold the tooth in place in the block against centrifugal forces. The cutting assembly is adapted to be mounted between two collars on a brush cutting drum with the cutting tooth above the periphery of the collars.
