Abstract: A wood chip collection system having a stump grinding wheel, a chip chute and a chip collection bin. The chute is positioned such that chips generated by the rotation of the wheel when engaged in a stump will be directed into the chute. The chute, in turn is sized and shaped to permit the energy in the chips to move the chips into a collection bin. The bin is positioned adjacent to and in alignment with the trailing edge of the chute in order to effectively receive the chips.

Abstract: 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.

Abstract: A stump grinding wheel tooth assembly having a mounting block positioned around the periphery of the wheel and a cutting bit attached to the mounting block by a pin passing through a hole in the cutting bit and a corresponding hole in the mounting block and capped by a nut. The mounting block may support multiple cutting bits arranged into a predetermined patterns based on the location of the holes, such as pairs of cutting bits or even a quad formation. The cutting bits may be provided in various geometric configurations, such as round, triangular, square, rectangular, pentagonal, hexagonal, octagonal or decagonal.

Abstract: A rotating disc assembly for use on a stump grinder includes a rotating disc defining a peripheral edge, a first side and a second side, and a central axis positioned through a central position of the rotating disc; a first cutting bit mechanically connected to a first position on the peripheral edge of the rotating disc; and a first shield assembly mechanically connected to a second position on the peripheral edge of the rotating disc in front of the first cutting bit, wherein the first shield assembly comprises a first footprint formed by a first portion extending a first radial distance from the central position and extending a first axial distance from at least the first side or the second side, wherein a footprint of the first cutting bit is at least partially shielded by the first footprint of the first portion of the first shield assembly.

Abstract: The present invention relates to grinding tools and, more particularly, to outdoor grinding tools, and also more particularly to rotating disc assemblies (including a disc, bit subassembly, and cutting bit shield/guard assembly). The rotating disc assembly can be used for grinding tree stumps, among other things.

Abstract: The present invention is generally directed to a bit assembly that includes, but is not limited to: a bit securing sub-assembly including a bit holder member that defines a recess having a first portion extending in a first direction, and a second portion extending from the first portion along a second direction that is not parallel to the first direction; a bit mechanically connected to the bit holder member and positioned within the recess by a fastening hardware that extends through co-axially aligned holes formed in the bit holder member and the bit; and a bit shielding sub-assembly comprising a bit shielding member mechanically connected to and extending from the second portion of the bit holder in a third direction that is substantially parallel to and spaced from the first direction; wherein the bit shielding member is structured, positioned, and/or located to at least partially shield the bit in the first direction.

Abstract: A wheeled chassis to which a stump grinding unit is securely attached that includes a chip collector attached to either the stump grinder or the wheeled chassis and positioned adjacent the trailing edge of the stump grinding wheel. The wheeled chassis includes a duct in fluid communication with the chip collector, and a collection bin positioned adjacent the trailing end and in spaced relation below the duct. The wheeled chassis is adapted for hitched connection to a vehicle. A blower can be positioned within the duct to produce a rearwardly directed air flow to assist in the chip movement towards the collection bin. The collection bin can be positioned on the wheeled chassis or on a vehicle to which the wheeled chassis is attached.
