Patent attributes
A tool carrier assembly of an earthworking implement is comprised of two components that contact a surface being worked; an earthworking tool and a depth guide. The tool carrier assembly is pivotably connected to a support structure. The support structure is removably attached to a lift arm assembly of a motive source. As the front wheels of the motive source are raised off the ground by downward force applied to the lift arm assembly, the depth guide assumes the function of bearing the load of the implement and a portion of the motive source. The vehicle steered and powered by the rear wheels may then move in any direction and the tool carrier assembly will articulate on a controllably variable vertical axis. As the earthworking tool moves material on the surface, the tool carrier pivots about a controllably variable horizontal axis to maintain contact with the surface as the tool carrier assembly pivots in response to uneven terrain.
