A stump cutting tool for use with a stump cutting apparatus of the type utilizing a cutting wheel or drum rotating about a rotational axis, wherein the cutting tooth is attached to the cutting wheel or drum, the cutting tooth comprising:
- a pocket removeably secured to the stump cutting apparatus, said pocket having a bore extending from a distal end of said pocket to a proximal end of said pocket, said proximate end being the end closer to the axis or rotation;
- and
- a cutting tool disposed in retained within said bore, said cutting tooth having a cutting tip attached thereto.
A cutting tooth for use with a stump cutting apparatus.
- an elongated body having a longitudinal axis and a distal end and a proximal end, said proximal end being that end closer to the rotational axis of the cutting wheel when the cutting tooth is attached thereto, said elongated body including a lateral axis and a head portion located on the distal end of said elongated body, said head portion including a front surface, a rear surface disposed laterally behind said front surface, and opposing side surfaces extending laterally from said front surface to said rear surface;
- a shank portion located on the proximal end of said elongated body, said shank portion including a retaining assembly;
- and
- a shoulder, said shoulder extending between said head portion and said shank portion, said shoulder including a shoulder surface.
A cutting tooth for use with a stump cutting apparatus of the type utilizing a cutting wheel or drum rotating about a rotational axis, wherein the cutting tooth is attached to the cutting wheel or drum, the cutting tooth comprising:
- an elongated body having a longitudinal axis and a distal end and a proximal end, said proximal end being that end closer to the rotational axis of the cutting wheel when the cutting tooth is attached thereto, said elongated body including a lateral axis;
- a head portion located on the distal end of said elongated body, said head portion including an arcuate front surface, a rear surface disposed laterally behind said front surface, and opposing side surfaces extending laterally from said front surface to said rear surface;
- a cutting tip attached to said front surface;
- a shank portion located on the proximal end of said elongated body, said shank portion including a plurality of threads;
- and
- a shoulder, said shoulder extending rearwardly on an incline between said shoulder portion and said head portion, said shoulder including an arcuate shoulder surface.
A cutting tool for use with a stump cutting apparatus of the type utilizing a cutting wheel or drum rotating about a rotational axis, wherein the cutting tool is attached to the cutting wheel or drum, the cutting tool comprising:
- a pocket that can be secured to the cutting wheel, said pocket having a bore extending from a distal end of said pocket to a proximal end of said pocket, said proximal end of said pocket being that end closer to the axis of rotation of the cutting wheel;
- a cutting tooth having a front face and a cutting tip secured on said front face, said cutting tooth disposed and retained within said bore;
A cutting tool for use with a stump cutting apparatus of the type utilizing a cutting wheel or drum rotating about a rotational axis, wherein the cutting tool is attached to the cutting wheel or drum, the cutting tool comprising:
- a pocket that can be secured to the cutting wheel, said pocket having a bore located between an inner face and an outer face of said pocket and extending from a distal end of said pocket to a proximal end of said pocket, said proximal end being that end closer to the axis of rotation of the cutting wheel, said pocket further including a notch extending rearwardly from said bore toward a trailing surface of said pocket, a lower surface of said notch forming a seat, wherein at least a portion of said seat is a concave arcuate surface and the proximal end of said pocket having a cutout area, a portion thereof defining an engagement surface;
- and
- a cutting tooth having an elongated body having a longitudinal axis with a distal end and a proximal end, said proximal end being that end closer to the rotational axis of the cutting wheel when the cutting tooth is attached via the pocket to the cutting wheel, said elongated body including a lateral axis, a head portion located on the distal end of said elongated body, said head portion including a front surface, a rear surface disposed laterally behind said front surface and opposing side surfaces extending laterally from said front surface to said rear surface, a shank portion located on the proximal end of said elongated body, said shank portion including a threaded portion, and a shoulder, said shoulder extending between said shank portion and said head portion, said shoulder including a shoulder surface at least a portion of said shoulder surface is a convex arcuate surface, wherein said cutting tooth is disposed is said bore such that a portion of the threaded portion of said shank portion extends through said bore, past said engagement surface and into said cutout area such that said shoulder surface of said cutting tooth engages said seat of said pocket;
- and
- a nut threadably placed on said threaded portion of said shank portion engages said engagement surface of said cutout area to retain said cutting tooth on said pocket.
