摘要： Embodiments in this disclosure include a cutting tool mounting block that is securely mounted to the periphery of a wheel. The mounting block includes a body portion with a channel having a width that expands along the length of the body portion. The cutting tool mounting block also includes an aperture configured to accept a single cutting tooth, in some embodiments. The cutting tool mounting block may also include a front feature that creates a clearance between the cutting tooth surface and the body portion. Some embodiments include the assembly of three mounting blocks on a stump grinder wheel, which can increases the bite each tooth takes, it can decrease the drag in the cutting wheel, and it can decrease chip recirculation.

摘要： A stump cutting assembly mounted to a stump cutting wheel. Stump cutting assembly is a stump cutting tooth interconnected to the wheel by a holder or block that is fixed to wheel by welding or other equivalent process, an optional debris deflector and a fastener that interconnects tooth and deflector to holder. As wheel rotates about its axis of rotation, the tooth cuts away at wood or other debris in which it comes into contact through the side to side and/or longitudinal movement of a stump grinder unit.

摘要： A stump grinder is configured to mount to a portable machine that operably supports the stump grinder during a stump grinding procedure. The stump grinder includes a cutting wheel that is rotatably driven during the stump grinding procedure. The cutting wheel has a cutting surface to grind the stump by moving the rotating cutting wheel across the stump. A wheel stabilizing assembly is disposed between the portable machine and the drive system for supporting the drive system and cutting wheel. The cutting wheel is held in a generally vertical orientation and movement of the cutting wheel is biased relative to the portable machine. Accordingly, forces applied against the cutting surface of the cutting wheel during the grinding procedure are limited by the biased movement.

摘要： A cutter holder has two limbs extending at an angle to each other. A cutter is mounted on one side of the cutter holder. An opposite side of the cutter holder has a prism-shaped cavity defined thereon. The cavity has a V-shape cross-section having a recessed groove at a base of the V-shape. A center line of the recessed groove is laterally offset from a center line of the cutter holder.
