摘要： A cutting wheel for use with a stump cutting apparatus. A plurality of tool holders are secured to the cutting wheel, and there are a plurality of apertures in each tool holder. Each aperture has a cutting tool or tooth mounted therein so that each tool holder supports more than one cutting tool or tooth. In some embodiments, the cutting wheel includes first and second sections. The first and second sections including a support member, with a tool holder attached to the support member. Each of the first and second sections having a notch therein, the respective notches cooperating to form a joint between the first and second sections.

摘要： A stump grinding wheel assembly having a disk-like wheel body. A plurality of bilateral mounting stations integral with the wheel body and arranged into spiral cluster groups. Each spiral cluster having an inner mounting station and at least one middle mounting station and an outer mounting station. The inner mounting stations are thicker than the middle mounting stations, which are thicker than the outer mounting stations. A pair of opposing side-cutters are disposed on each left and right side of the mounting stations. A separate plunge-cutter may be included with each spiral cluster. The bilateral mounting stations produce conically-helical cutting paths using identical side-cutters. The unequal width of the inner and middle and outer mounting stations enables better management of cutting forces in side cutting mode, which produces smoother operation.

摘要： FIG. 1 is perspective view of a tree stump grinding tooth according to the present invention shown in use attached to the leading end of tool holder;
FIG. 2 is front perspective view of a tree stump grinding tooth according to the present invention;
FIG. 3 is rear perspective view of a tree stump grinding tooth according to the present invention;
FIG. 4 is a right side elevation view of the tree stump grinding tooth, the left side and top plan and bottom plan views being mirror images thereof;
FIG. 5 is a front elevation view of the tree stump grinding tooth;
FIG. 6 is rear elevation view of a tree stump grinding tooth; and,
FIG. 7 is a cross-sectional view as taken generally along lines 7-7 of FIG. 5 to better illustrate the ornamental contours of the front face of the tree stump grinding tooth.
The broken lines in FIGS. 3, 4, 6 and 7 illustrate portions of the tree stump grinding tooth that form no part of the patented design. The broken lines showing the tool holder in FIG. 1 are provided for the purpose of illustrating environmental structure and do not form part of the claimed design.-

摘要： A tree stump grinding wheel assembly includes a rotor having a plurality of holders distributed about its cutting periphery. Each holder has a neck in which resides a socket adapted to receive the shank of an indexable tooth. A head is attached to one end of the shank and screw threads are formed in its other end. The head has a plurality of flats configured to sequentially register with a forward shoulder on the neck. A hermetic spring is operatively disposed on the shank between a rearward face of the socket and a retention nut. The hermetic spring is made of elastomeric material and has a tapered nose that self-seats in a countersink at the rearward opening of the socket. The hermetic spring has an accordion-like bellows section. The bellows section can have a central annular bulge.
