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 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.
