Abstract: A tip assembly includes a tip including a body having a narrow tip portion, a broad attachment portion that defines a concave surface, an interior disposed between the broad attachment portion and the narrow tip portion, and a cavity that leads from the concave surface toward the interior. A retention bolt that is heated includes a tapered region, and a shaft extending from the tapered region, terminating at an externally threaded end. The cavity of the tip is at least partially complimentarily shaped to the tapered region of the retention bolt.

Abstract: A radial bearing comprises a traditional bearing having a plurality of sinusoidal shaped wheels in place of traditional spheroid bearings. The race of bearing may also comprise a sinusoidal shape.

Abstract: Various aspects of a wheel rim for use with agricultural equipment, such as an irrigation system are disclosed. In one example, the wheel rim includes first and second concentric rim plates separated by a distance, each of the first and second concentric rim plates having an outer surface. The wheel rim further includes a plurality of cross members spanning the distance.

Abstract: An enhanced traction device for use with a vehicle having dual tandem wheels includes a series of generally parallel track pads, each track pad having an alignment portion and a traction portion defining first and second ends. Each traction portion includes an inner surface for contacting the vehicle wheels and an outer surface for contacting ground. Each alignment portion extends away from a respective traction portion outer surface and is configured to pass between the dual wheels. The alignment portions maintain proper positioning of the track pads upon the dual tandem wheels of the vehicle. The traction device further includes a first chain coupled to each respective track pad first end for maintaining a predetermined spacing between said track pad first ends. Similarly, the traction device includes a second chain coupled to each track pad second end for maintaining a predetermined spacing between the track pad second ends.

Abstract: A rotary walking device having multiple sequential ground engaging elongated struts interconnected between pairs of annular drive disks. Each pair of drive disks having multiple pivot attachment points for the respective opposing apertured ends of each strut. Each strut having angularly offset parallel engagement ends which engage with spaced co-parallel drive disks affording a unique rotational linear travel path that allows each of the struts to sequentially engage the ground and propel the assembly forward in a progressive walking like motion when used in combination with corresponding second strut drive assembly.

Abstract: A beach cart having a first frame member and a second frame member, the first frame member being pivotably attached to the second frame member; a first payload carrier rotatably attached to the first frame member and removably attached to the second frame member; a second payload carrier pivotably attached to the first frame member and removably attached to the second frame member; a third payload carrier pivotably attached to the second frame member; a first wheel riser and a second wheel riser attached to the first frame member; a first wheel mounting block and a second wheel mounting block removably attached to the first wheel riser and the second wheel riser, respectively; a wear bearing and a second wear bearing mounted in the first wheel mounting block and the second wheel mounting block, respectively; and a roller assembly having a first end cap having a first stub axle and a second end cap having a second stub axle, the first stub axle being mounted within the first wear bearing and the first wheel mo

Abstract: A compactor wheel that is mountable on an axle of a compaction machine and that automatically adjusts for compacting low density and high density refuse. The compacting surface of the compactor wheel is effectively wide when compacting low density material and narrower when compacting higher density material. The compactor wheel includes a hub, a rim and a plurality of cleats. The rim is mounted around the outer circumference of the hub and has a face with at least one smaller diameter section and at least one larger diameter section. The cleats are mounted to the larger diameter section(s) of the face. The one or more larger diameter sections of the face enable the compactor wheel to concentrate the weight of the compaction machine while the compaction machine is compacting relatively high density material.

Abstract: An irrigation system tower support wheel for use in combination with an irrigation system having one or more tower supports, irrigation means and drive means, the support wheel including a generally cylindrical wheel rim having outer and inner surfaces, first and second edges and a center longitudinal axis, the wheel rim having a generally flat cross-section. The wheel rim further includes first and second inwardly extending peripheral side flanges connected to the first and second edges respectively such that additional rigidity may be imparted to the cylindrical wheel rim. Support struts extend inward towards the center longitudinal axis of the wheel rim, the support struts mounted on the inner surface of the wheel rim. The outer surface of the wheel rim includes a plurality of lugs for improving traction of the wheel. Each of the lugs consists of a longitudinally extended channel having a V-shaped cross-section.

Abstract: A traction wheel has a pair of axially spaced apart annular rims presenting ground engagement surfaces which are inclined radially and axially inwardly toward one another to form the ground into a mound on which the wheel rides. A series of wedge-shaped lugs span the rims in circumferentially spaced apart relation. One of the inclined sides of several of the lugs extends radially inwardly to serve as a spoke for the rim. Each lug is generally V-shaped with an apex directed radially outwardly. An opening is formed through the apex both to increase traction and to dissipate any vacuum between the lug and ground.

Abstract: A tractor has three pairs of ground wheels: front and rear steerable pairs which cooperate to steer the tractor, and a central pair. The central pair of wheels each are connected to the frame through a hydraulic cylinder and piston assembly which can be controlled to raise those wheels above the ground or to lower the wheels to engage the ground. The central wheels can be the same as the other wheels or traction caged wheels of hollow beams wherein a hub is connected to outer fellies with spokes. Supports interconnect the fellies at the inner or outer sides. All of the wheels can be driven independently by an engine and the central wheels are each detachable from a driven axle. The hub of the central wheels includes an outer cylindrical sleeve to which and end plate and the spokes are affixed. Each wheel is mounted on a hydraulic motor which is mounted on the tractor's frame, the forward and rear motors being turnable with the wheels mounted thereon.

Abstract: A flexible paddle wheel structure comprises a pair of axially spaced wheels, having flexible rims, such as, for example, pneumatic tires, with pairs of radially spaced, transverse, flexible members extending between, and attached to, the rims. A flexible membrane extends between the transverse members in each pair to form a flexible paddle. The wheels can tilt relative to each other and the whole structure can be arranged to be lifted and lowered.
