A wheel assembly for traversing a path along a ground surface having a layer of soil, the wheel assembly comprising a central support and an airless flexible covering mounted on the central support and having a plurality of rigid sections and a plurality of flexible sections. The outwardly protruding spokes urge the rigid sections into the layer of soil when the rigid sections contact the ground surface. The flexible sections flex inwardly when the flexible sections contact the ground surface so that the rigid sections and the flexible sections cooperatively form a corrugated pattern in the ground surface without urging the soil to side margins of the airless flexible covering, the corrugated pattern having a plurality of valleys formed by the rigid sections and a plurality of peaks formed by the flexible sections.

A tireless steel wheel for a skid steer features a cylindrical drum, a set of cleats projecting externally from the drum, a hub plate inside the drum an at intermediate location between opposing ends thereof, frustoconical walls flaring outward from opposing sides of the hub plate toward the respective ends of the drum, and annular end plates joining the wider ends of the frustotonical walls to the drum at the opposing ends thereof. The hub plate is offset from an axial center of the drum, and the frustoconical walls are unequal to one another in their angle of taper. The annular walls prevent the wheels from digging into the ground, and the frustoconical walls prevent material accumulation inside the wheels. The offset position of the hub plate provides flexible mounting options to accommodate varying dimensional characteristics of different skid steer models and bucket sizes.

A support wheel for an irrigation system may comprise a rim configured to contact the ground with a ground contact surface, with the rim having an inner surface and an outer surface forming the ground contact surface. The rim may have a first edge and a second edge, with the first edge lying in a first plane. A hub may be positioned at a center of the wheel and being configured to mount on an axle. A spoke structure may extend from the hub of the wheel to the rim of the wheel. The spoke structure may include a plurality of frames, and at least one of the frames may be mounted on the inner surface of the rim along a line extending from the first edge to the second edge of the rim in a non-parallel and non-perpendicular orientation to the first plane.

A wheel having a circular ring is provided. The circular ring has a rotational axis and an outer surface. A plurality of lugs is mounted in side-by-side positions on said outer surface of the circular ring. Each lug of the plurality of lugs has: a center rib, a first leg and a second leg, each leg extending from the center rib laterally and opposite of each other, and a lug plate adapted to connect the first leg to the center rib. The outermost point of each center rib may form a circular pattern that is coaxial with the rotational axis. The wheel may have a rim nested within said circular ring, said rim having a plurality of alternating scalloped protrusions, wherein said rim is configured to provide suitable clearance for tools during lug installation and removal while increasing the load capacity of said wheel.

Mobile equipment, such as landfill compactors, utilize wheels with wire guards to prevent wire, cable, or the like from entangling the mobile equipment. Traditional wire guards either do not satisfy life expectations or do not provide an edge that promotes chopping or cutting of refuse and/or traction. The disclosed wire guard comprises one or more chocky bars, extending between pairs of adjacent cleats on the peripheral edge of a circumferential surface of a wheel rim. This wire guard may improve the life of the wire guard system to match the life of the cleats, while also providing a serrated edge that improves chopping and cutting of refuse and provides traction on the varied and unpredictable terrain of a landfill.

A fully cast idler wheel may include an annular rim portion, an annular hub portion, and a plurality of beams extending between the annular rim portion and the annular hub portion. The plurality of beams may include a first set of beams and a second set of beams that extend between the annular rim portion and the annular hub portion on opposite axial sides of the fully cast idler wheel. Both the first set of beams and the second set of beams may be offset from each other both axially and circumferentially.
