Abstract: 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.

Abstract: A rigid wheel (18) or roller for a compactor machine, comprising a drum for contacting material to be compacted. The drum has a profiled outer surface including a first cylindrical portion (27) and a second cylindrical portion (29). The first cylindrical portion has a larger rolling diameter than the second cylindrical portion. An inclined portion (24) extends between the first and second cylindrical portions. The area of contact between the outer surface of the drum and refuse, soil or other material to be compacted varies with the depth of penetration of the wheel into the material. The different rolling diameters within the scope of one wheel gives different ground pressures. This means that the pressure applied to the material for compaction varies depending upon the depth of penetration of the wheel. One benefit of this wheel/roller design is to allow improved go anywhere mobility—high floatation where needed changing to heavy ground pressure where conditions demand.

Abstract: The present invention is a device that aerates lawn or soil using a unique triangular shaped tine or spike. The spikes are arranged on drums in a pattern. The drums can be filled with a fluid such as water or a granular material such as sand to adjust the depth to which the spikes penetrate. The drums may be angled with respect to the direction of travel to impart a transverse movement to the soil. The triangular shape of the spikes and the transverse movement greatly enhances the degree of aeration and results in significantly better aeration compared to using round spikes and coring devices. The surface is not cluttered with cored debris, so the present invention can be used on playing fields or lawns where post aeration appearance is important.

Abstract: In the operation of a landfill compactor it is a common problem for the wheels to pick up debris, especially wire and cable, and carry it around the wheel as they rotate.
