Claim:
1. A tree removal device, the device comprising: a housing; a shaft; a bit assembly comprising a pilot bit and a cutting portion; a stabilizing portion; the housing comprising one or more vertical walls, one or more horizontal walls, first and second vertical sliding members, a connection plate, and a base plate; the baseplate comprising a front portion, a lower portion of the one or more vertical walls being coupled to the front portion; wherein one or more of the one or more horizontal walls is coupled to one or more of the one or more vertical walls; said connection plate being adapted for coupling to a cooperative coupling plate of a tractor; the shaft, bit assembly, and stabilizing portion each sharing a central longitudinal axis; said shaft and bit assembly being rotatable around the central longitudinal axis, the stabilizing portion and housing being non-rotatable around the central longitudinal axis; the bit assembly being coupled to a lower end of the shaft; the stabilizing portion being tubular, such that a hollow space is defined by an inner wall extending between stabilizing portion upper and lower ends; said stabilizing portion upper end being coupled to the base plate; the first vertical sliding member being slidingly coupled to the second vertical sliding member such that the stabilizing portion may be moved from a first position to a second position; the cutting portion extending radially from a position proximate to the central longitudinal axis such that a central portion of the cutting portion is proximate to the central longitudinal axis and a cutting portion end is positioned distal from the central longitudinal axis; said bit assembly, when the stabilizing portion is in the first position, being positioned within the hollow space of the stabilizing portion such that the cutting portion end is proximate to the inner wall of the stabilizing portion; and said bit assembly, when the stabilizing portion is in the second position, being positioned outside the hollow space such that the cutting portion end is below the lower end of the stabilizing portion.
