Patent attributes
A tractor-mounted three-point-hitch implement, powered by the tractor power-take-off, with a rotational excavating apparatus for the excavation of linear depressions, including foundation footings, ditches and trenches. The rotational excavating apparatus for footings or trenches, having flat horizontal base and straight vertical sides, is cylindrical, drum-shaped, and made in sections, to allow for changes in width of depression. It is surfaced with claws and it rotates opposite the direction of the implement's movement, placing excavated spoils on the banks. The drum-shaped rotational excavating apparatus is removable for installing different sizes and shapes of rotational excavating apparatuses. A rotational excavating apparatus of spherical shape is used to form circular or rounded-U-shaped ditches, and one of prolate ellipsoid shape is used to form parabolic or rounded-V-shaped ditches that are shallow and easily mowed. The depth of cut is adjustable by the hydraulic lift on the tractor.
