Abstract
A tool assembly for attachment to a cutter wheel for use in tree stump removal is described. The assembly includes a tooth and a pocket. The tooth includes a cutting head and a shank depending from the head. The shank includes a first flat opposite a second flat. The pocket defines opposing wheel and exterior faces. A tooth receiving slot is formed in the wheel face and includes a base. In this regard, the tooth shank defines one of a projection and a recess and the pocket defines the other of the projection and the recess. Upon coupling the tooth shank to the tooth receiving slot, substantially an entirety of a peripheral edge of the projection contacts a wall of the recess to resist a torque applied to the cutting head.

A tool assembly for attachment to a cutter wheel for use in tree stump removal, the assembly comprising:
- a tooth including a cutting head and a shank depending from the head, the shank including a first flat opposite a second flat;
- and
- a pocket including:
- opposing wheel and exterior faces, and
- a tooth receiving slot formed in the wheel face and including a base;
- wherein the tooth shank defines one of a projection and a recess and the pocket defines the other of the projection and the recess;
- further wherein upon coupling the tooth shank to the tooth receiving slot, substantially an entirety of a peripheral edge of the projection contacts a wall of the recess to resist a torque applied to the cutting head.
A cutter wheel assembly rotatably disposed on a tree stump removal machine, the assembly comprising:
- a cutter wheel;
- and
- at least two tool assemblies cooperatively coupled to the cutter wheel, each tool assembly including:
- a tooth having a cutting head and a shank depending from the cutting head, the shank including a first flat opposing a second flat, and
- a pocket defining opposing wheel and exterior faces, and a tooth receiving slot formed in the wheel face;
- wherein each tooth shank defines one of a projection and a recess and each pocket defines the other of the projection and the recess;
- further wherein each tooth receiving slot couples with a corresponding one of the teeth shanks with a zero clearance fit between the respective projections and the recesses.
A method of attaching a cutting tooth to a cutter wheel rotatably disposed on a tree stump removal machine, the method comprising:
- providing the tooth, the tooth including a cutting head and a shank depending from the head, the shank including a first flat and a second flat;
- providing a pocket, the pocket defining opposing wheel and exterior faces, a tooth receiving slot formed in the wheel face;
- configuring the tooth shank to define one of a projection and a recess;
- configuring the pocket to define the other of the projection and the recess;
- snap fitting the projection into the recess to form an assembly such that substantially an entirety of a peripheral edge of the projection contacts a wall of the recess;
- and
- attaching the assembly to the cutter wheel;
- wherein the projection and the recess tightly couple to resist a torque applied to the tooth.
