Abstract
A subterranean plow blade for mounting onto a tractor in a clamping fashion for fast and easy mounting and removal. A blade holder is affixed to a tractor, and clamp pieces are pivotly mounted on the holder with one piece thereof engaging the blade and the other pieces forcing the first one piece tightly against the blade for holding same. The holding pieces are adjustably interrelated to accommodate variations in piece and blade sizes. The blade is arranged with a leading edge which penetrates the ground and has its intermediate portion sharpened while the portion above and below that intermediate sharpened portion is blunt or unsharpened, all for maximum functioning in moving through the ground. Also, the blade has notches on its leading and trailing edges for the ready mounting with the blade holder.
