The lug bar includes a base, having a bar shape and made of a first metal, and an overlay, extending along the longitudinal direction of the base to cover a covered region as a part of the outer peripheral surface of the base. In an overlay edge portion corresponding to a boundary between the covered region and an exposed region other than the covered region of the surface of the base, the exposed region and the surface of the overlay are flush with each other to form a forged surface.

The present invention provides an embedded-outer rotor motor direct driven mower driving wheel and a mower. The embedded-outer rotor motor direct driven mower driving wheel comprises a driving wheel main body formed by the assembling of a wheel side cover I, a wheel side cover II, and a wheel body sandwiched between the wheel side cover I and the wheel side cover II, the wheel side cover I, the wheel side cover II and the wheel body are enclosed to define a cavity, an outer rotor motor is mounted in the cavity, an outer rotor portion of the outer rotor motor is fixedly arranged relative to the driving wheel main body, an internal stator portion of the outer rotor motor is provided with a fixed shaft penetrating through the wheel side cover I and extending out of the driving wheel main body, and the wheel side cover I is provided with a shaft hole I allowing the fixed shaft to penetrate through. The present invention arranges the outer rotor motor inside the driving wheel and directly drives the mower driving wheel through the outer rotor motor, thus, transmission precision and reliability are good, and the inner space of the mower is more reasonable.

A traction aid for a motor vehicle, comprising an elongated main body having a top and a bottom surfaces, the elongated main body having thereon a series of teeth and a sliding mechanism, a first securing member located at an end of the main body and projecting downwardly and a second securing member located at the bottom surface of the main body and attached to the sliding mechanism. The sliding mechanism allows movement of the second securing member towards or away from the first securing member along the bottom surface of the main body. The traction aid further comprises a securing mechanism configured to move the sliding mechanism and the second securing member towards the first securing member in order to squeeze a tire of the motor vehicle between the first and second securing members.

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.
