Abstract
A cutting tooth for use in a stump cutting apparatus wherein the cutting tooth comprises a mounting base and a head portion which are integral with one another and are made of a one-piece metallic forging. The forging is preferably made from AMS 4140 steel and the cutting tooth further comprises a cutting tip, preferably of tungsten carbide, which is fixedly attached to the head portion of the tooth. The disclosed preferred embodiments include those in which the head portion is disposed in a substantially straight line relationship with the mounting base and those in which the head portion is curved relative to the mounting base. The disclosed embodiments of the cutting teeth are suitable for attachment in matched pairs to a vertical, rotatable disk, or cutting wheel of the stump cutting apparatus, with the head portions being curved relative to the corresponding base portions so as to curve away from the disk, or, alternatively, disposed in a substantially straight line relationship with the corresponding base portion.
