Claim:
1. A bandsaw assembly comprising: a horizontally-oriented frame that is rectangular in shape: ground-engaging wheels or a ground-engaging track provided on the frame; said wheels or track being adapted to rest upon a flat surface; four spaced apart towers extending vertically upwardly from the frame, wherein each tower is located proximate a different corner of the frame; four rotatable drive wheels, each of said four rotatable drive wheels being mounted on a different one of the four towers; each said four rotatable drive wheels being horizontally oriented and presenting a vertically oriented circumferential surface; and wherein each of said four rotatable drive wheels is separately positionable by the associated tower at an adjustable distance above the frame; an arm extending outwardly from a first one of the four towers toward a second one of the four towers: a fifth rotatable drive wheel mounted on the arm and being located proximate to a first two of the four drive wheels and remote from a third drive wheel and a fourth drive wheel of the four drive wheels; said fifth drive wheel being horizontally oriented and presenting a vertically oriented circumferential surface: a motor operatively engaged with one or more of said four rotatable drive wheels; and a bandsaw blade passing around all five of the rotatable drive wheels and being in contact with the circumferential surfaces thereof; said blade being driven by all five of the rotatable drive wheels; and wherein each of the four towers is variable in length and when the length of the four towers is varied, each of the four drive wheels is thereby moved further away from the frame or closer to the frame to separately change the adjustable distance above the frame for each of the first two of the four drive wheels, the third drive wheel, and the fourth drive wheel; and the movement of the four drive wheels thereby raises or lowers the bandsaw blade relative to the frame.
