Abstract: Although a radial outside portion of a metal ring contact surface of a neck section of a metal element which is contactably opposed to a side edge of a metal ring of a metal ring assembly has high frequencies of contacting with a side edge of the metal ring, it is possible to suppress abrasion of the side edge of the metal ring and to improve durability of the metal ring by setting a surface hardness of the radial outside portion lower than a surface hardness of the metal ring. In addition, by setting a surface hardness of the metal ring contact surface at its portion of the radial outside lower than the surface hardness of the metal ring contact surface at other portions thereof where the frequencies of contacting with the side edge of the metal ring becomes low, in comparison with a case of setting the surface hardness of the whole metal ring contact surface low, it is possible to increase strength of the metal element and to improve the durability of the metal element.

Abstract: An apparatus for driving and braking a cutting blade of a lawn mower is disclosed. The apparatus includes a shaft extending through a housing for rotating the blade, and an engine-driven pulley. The apparatus includes means for biasing the pulley toward the housing, and means for translating the pulley away from the housing. The apparatus has a stopped position in which the pulley and housing are in friction contact, and a cutting position in which the pulley and housing are not in friction contact. When the engine delivers power to the pulley, the apparatus moves from the stopped position to the cutting position such that the pulley and the housing are not in friction contact and the blade rotates. When power delivery to the pulley ceases, the apparatus moves from the cutting position to the stopped position, placing the pulley and housing in friction contact, and the blade stops.
