Abstract

A cutting system includes a wheel, a tooth and a fastener. The wheel has a hub, a periphery, a side that extends from the hub to the periphery, and a receiver located on the wheel's side. The hub has a longitudinal axis about which the wheel may rotate, and the receiver includes a bearing surface. The tooth is mounted to the wheel's receiver and includes a blade and a mount. The blade cuts material when the wheel rotates about the hub's longitudinal axis and the blade contacts the material. The mount couples the blade to the wheel's receiver. The mount includes a first interface where the blade couples with the mount, and a second interface where the mount couples with the wheel's receiver. The mount's 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. The fastener 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, and specifically does not include the bearing surface of the tooth's mount.
