1. An apparatus comprising:

  • a frame configured for towing behind a vehicle, the frame having a width and a length extending perpendicular to one another, and a height extending perpendicular to the width and the length;

    first and second ground contacting wheels rotatably coupled with the frame at spaced part locations along the width of the frame, the ground contacting wheels supporting the frame at a height above a ground surface with the ground contacting wheels in contact with the ground surface;

    a tool support pivotably coupled with the frame; and

    a cleaving blade adjustably coupled with the tool support, the cleaving blade extending over a length from a front edge to a rear edge, extending over a height from an upper surface to a lower surface, and extending over a width along the width of the frame, wherein the length of the cleaving blade is greater than the height of the cleaving blade and the width of the cleaving blade is greater than the length of the cleaving blade;

    wherein, when the ground contacting wheels are in contact with a ground surface, the tool support is pivotable relative to the frame to a first position in which the entire cleaving blade is positioned above the ground surface and to a second position in which the entire cleaving blade is positioned at a depth below the ground surface and the upper surface is parallel with a plane extending along the length and the width of the frame and perpendicular to the height of the frame;

    wherein the depth of the cleaving blade below the ground surface is variable by adjusting the position of the cleaving blade relative to the tool support while the tool support is in the first position; and

    wherein the tool support is further pivotable to a third position in which the entire cleaving blade is positioned below the ground surface and the angle of the upper surface of the cleaving blade relative to the ground surface is varied relative to the second position.
