ABSTRACT:
A new design and configuration for tree stump cutting tooth and its corresponding holding bracket. Notch(s) on the tooth and rib(s) on the bracket are used to allow fast installation of tooth without gauging, reduced the time needed for such necessary tasks. The notch/rib structure also increases the clamping power of the bracket, reducing the possibility that any tooth would fly out, due to the centrifugal force, and cause injury. Wide notches are employed on certain heavy-duty tooth and allow the installation to be done quickly in two positions, and a small range in between the two positions.
