A traction device for installation between a set of dual wheels on a vehicle, the traction device including a wheel attachment plate, at least one leg and at least one paddle. The wheel attachment plate is centrally coupled between each of the wheels. The at least one leg is coupled to the wheel attachment plate between the wheels. The at least one paddle is coupled to the leg and positioned radially outward from the wheel attachment plate.

A wheel includes a circular wheel main body and at least one grouser. The at least one grouser is provided along an outer circumference of the wheel main body and has a contact surface capable of drawing a first tangent line. The first tangent line is inclined opposite to a rotational direction of the wheel main body from the center line of the wheel main body.

A circular wheel is aligned in a rotational plane and has a peripheral outfacing surface symmetrical about the plane of rotational. A center line of the width of the peripheral outfacing surface is sinusoidal around the wheel. The wheel may have a central hub, a rim, a medial wheel structure between the hub and the rim, and a tire mounted on the rim. The outfacing surface may be that of the hub, the medial wheel structure, the rim, or the tire depending on the application.

A non-pneumatic tire assembly includes a non-pneumatic tire. The non-pneumatic tire includes an inner circumferential ring and an outer circumferential ring defining an annular space and a cylindrical space inside the inner circumferential ring. A plurality of partitions connect the circumferential rings within the annular space. A ground-contacting tread is located on the outer circumferential ring. A rim, including a plurality of pieces, is located within the cylindrical space. The non-pneumatic tire assembly further includes a hub that is removably connected to the rim.

A turf wheel having a wheel rim having an inner and outer surface, and an annular tread portion; a plurality of projections extending radially outward from the outer surface of the wheel rim, wherein each projection provides a stem, a ground contacting pad, and a ground engaging lug; and a hub. A wheel cleaning system having a frame provided by a wheeled apparatus; at least one turf wheel mounted to the frame; a turf wheel scraper assembly, the turf wheel scraper assembly providing a turf wheel scraper and an attachment mechanism, where the attachment mechanism is adapted to be mounted to the frame, and couples the turf wheel scraper to the frame.

A wheel includes a circular wheel main body and at least one grouser. The at least one grouser is provided along an outer circumference of the wheel main body and has a contact surface capable of drawing a first tangent line. The first tangent line is inclined opposite to a rotational direction of the wheel main body from the center line of the wheel main body.

A transformable wheel and method of transforming a wheel between open and closed positions. An exemplary transformable wheel may include a plurality of wheel segments (legs), including at least one passive leg and at least one active leg. The active leg(s) is actuated by a powered active leg transformation mechanism, while the passive leg(s) is actuated by a passive leg actuation mechanism that employs an elastic element, spring, or other passive actuator to automatically move the passive leg(s) toward the current position of the active leg(s).

An irrigation wheel traction lug, comprising a lug having a bent-paddle, a base and a one or more chains. Said bent-paddle comprises a first side, a second side and a front portion. Said bent paddle comprises a substantially V shape when viewed from above. Said first side and said second side flare backward away from a front portion of said base portion toward a rear edge. and Said lug selectively attaching to an irrigation wheel, having a tread pattern and a rim, by placing said base on said treat pattern, wrapping said one or more chains around said irrigation wheel between said rim and said tread pattern, and securing said lug to said irrigation wheel with said base and said one or more chains.
