A system for grinding stumps and clearing brush, and related methods and devices

A wheel for a cutting system for grinding stumps and cutting brush, the wheel comprising:

• a hub having a longitudinal axis about which the wheel rotates;
• a periphery;
• a side that extends from the hub to the periphery;
• a receiver located on the side and configured to mimic and nest with a second interface of a tooth's mount, wherein the receiver includes a bearing surface that receives from the mount's second interface loads that the material exerts on the blade while the blade cuts the material;
• and
• a hole that extends into the wheel and is sized to receive and hold a fastener when the tooth's mount is secured to the cutting system's wheel.

A cutting system for grinding stumps and cutting brush, the system comprising:

• a wheel having a hub, a periphery, a side that extends from the hub to the periphery, and a receiver located on the side, the hub having a longitudinal axis about which the wheel can rotate, and the receiver includes a bearing surface;
• a tooth mounted to the receiver of the wheel, the tooth comprising:
• a blade that cuts material when the wheel rotates about the hub's longitudinal axis and the blade contacts the material, and
• a mount that couples the blade to the wheel's receiver, the mount having a first interface where the blade couples with the mount and a second interface where the mount couples with the wheel's receiver, wherein the second interface is configured to mimic and nest with the wheel's receiver and includes a bearing surface that transmits to the bearing surface of the wheel's receiver loads that the material exerts on the blade while the blade cuts the material;
• and
• a fastener that secures the tooth to the wheel and holds the bearing surface of the mount's second interface against the bearing surface of the wheel's receiver, wherein the fastener does not include the bearing surface of the tooth's mount.
