Stump cutting tooth assembly
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.
1. A stump cutting assembly adapted for mounting to a stump cutting wheel wherein the cutting wheel is adapted to rotate about an axis of rotation, comprising:
a. a cutting tooth comprising first and second cutting bits defining first and second opposed sides, first and second cutting edges, wherein each of said first and second cutting edges extend in a direction along a plane that is non-parallel to the axis of rotation when said tooth is assembled on the cutting wheel, a front edge extending between said first and second side cutting edges, an upper surface from which said first and second opposed side cutting edges extend, and a bottom surface that is opposite to said upper surface;
b. a holder adapted for integral attachment to the cutting wheel and comprising a bottom surface adapted to be positioned in contacting relation to said upper surface of said cutting tooth when said cutting tooth and said holder are assembled on the cutting wheel; and
c. an elongated fastening member adapted for extension through said bottom and upper surfaces of said cutting tooth and through said bottom surface of said holder, whereby said fastening member securely attaches said cutting tooth to said holder.
2. The stump cutting assembly according to claim 1 , further comprising a deflector having an upper surface adapted to be positioned in contacting relation to said bottom surface of said cutting tooth and through which said elongated fastener passes when assembled with said cutting tooth and said holder.
3. The stump cutting assembly according to claim 2 , wherein said deflector comprises first and second opposed side surfaces shaped in a predetermined manner to deflect debris that is cut by said cutting tooth.
4. The stump cutting assembly according to claim 3 , wherein said predetermined shape is concave.
5. The stump cutting assembly according to claim 2 , wherein said a top surface of said deflector extends away from said wheel and beyond the position of said first and
second side cutting edges when said tooth is assembled on the cutting wheel.
