The tool is mounted on a tractor which moves over the ground and forms a cut in the ground, and mounting members support the tool from the tractor in various angled positions depending upon the desired angle for presenting the tool cutting edge in the ground. Mounting members between the tractor and the tool are adjustable for adjusting the ground cutting angle.
