Abstract
A towable tool includes a frame extending over a width in an X-axis direction, a length in a Y-axis direction, and a height in a z-axis direction. A plurality of ground-contacting support wheels are rotatably coupled with the frame. A plurality of ground-working discs each rotatably coupled with a respective rigid shank. Each rigid shank is received and selectably retained in a respective receptacle of the frame.
Claims19
A towable tool apparatus comprising:
- a frame extending over a width in an X-axis direction, a length in a Y-axis direction, and a height in a z-axis direction;
- a plurality of support wheels rotatably coupled with the frame and configured to support the frame above an underlying ground surface in at least a first state of adjustment of the towable tool apparatus;
- and
- a plurality of ground-working discs each including a concave face surface extending radially outward from an axis of rotation and each being rotatably coupled with a respective rigid shank, each rigid shank being received in a respective receptacle of the frame and retained therein by a respective fastener such that each concave face surface of a first set of the ground-working discs is oriented in a first forward-facing direction offset from the Y-axis direction and each concave face surface of a second set of the ground-working discs is oriented in a second forward-facing direction offset from the Y-axis direction, the first forward-facing direction being different than the second forward-facing direction;
- wherein the plurality of ground-working discs are arranged in a row extending along the X axis direction, are substantially coextensive in the Y-axis direction, and extend in the Y-axis direction to overlap entirely with the extent of the ground-contacting support wheels in the Y-axis direction.

- wherein a ratio of the mass of the towable tool apparatus to a number of the plurality of ground-working discs is equal to or greater than a minimum value defined by the equation y=0.12x+16 wherein y is the ratio of the mass of the towable tool apparatus to a number of the plurality of ground-working discs and x is the mass of the towable tool apparatus.
