Abstract: A plastic bushing for use with wheel assemblies for low speed, off-highway vehicles of the type of hand trucks, wheelbarrows and the like. The plastic bushing is constructed of two substantially identical bushing members molded of a self-lubricating, preselected plastic and each having a flanged end for abutting the central opening of a wheel assembly. Each plastic bushing member is provided with diametrically spaced locking fingers with locking windows defined in the body of the bushing members for snap-locking to the locking fingers when aligned within the wheel assembly opening.

Abstract: An agricultural wheel assembly constructed of a plastic wheel half and a metal half releasably secured together for use with agricultural row crop planters and grain drills. The plastic wheel half has a smooth flat or shallow cup for eliminating the problems related to "rooster tailing". The metal wheel half having a deep cut configuration for clearance when mounted on the agricultural equipment and exhibiting structural strength above and beyond that of the plastic wheel half. The wheel halves are releasably but tightly locked together. An improved clincher base tire for the plastic-metal wheel assembly having an offset tire lip for depth/gauge control and a base having a dependent nose adapted to be snugly received at the juncture of the wheel halves for substantially eliminating soil infiltration between the tire and the wheel assembly when mounted on the plastic half.

Abstract: A portable hammock kit having aminimum of modular components for assembling and disassembling the modular components for storage or transportation to another location and store all components in a convenient carrying bag. The hammock stand can be assembled with three modular components without fasteners or tools. The hammock stand accommodates a hammock bed suspended from a pair of modular leg assemblies that allow for vertical adjustment of the elevation of both the head and foot ends of the hammock bed. A canopy can be readily mounted and dismounted over the assembled hammock stand.
