Abstract
The present subject matter relates to devices, systems, and methods for shaping complex contours using a grading tool that is pushed or pulled along the ground. The grading tool can include a ground-engaging blade comprising a leading edge having a substantially concave profile and a trailing edge having a substantially convex profile and a coupling element connected to the blade and configured to adjust an angle at which the blade contacts a ground surface.
Claims18
A grading tool comprising:
- a ground-engaging blade comprising a leading edge having a substantially concave profile and a trailing edge having a substantially convex profile;
- and
- a coupling element connected to the blade and configured to adjust an angle at which the blade contacts a ground surface.
A system for grading a ground surface, the system comprising:
- a grading tool comprising:
- a ground-engaging blade comprising a leading edge having a substantially concave profile and a trailing edge having a substantially convex profile;
- and
- a coupling element connected to the blade and configured to adjust an angle at which the blade contacts a ground surface;
- and
- a draft linkage assembly connected at a first end to the grading tool and at a second end to machine or vehicle;
- wherein the draft linkage is configured to move the grading tool relative to the machine or vehicle.
4 more elements
A method for grading a ground surface, the method comprising:
- positioning a grading tool at or near a ground surface to be graded, the grading tool comprising a ground-engaging blade comprising a leading edge having a substantially concave profile and a trailing edge having a substantially convex profile;
- adjusting an angle of the blade with respect to the ground surface;
- moving the blade with respect to the ground surface to produce a desired surface configuration.
