摘要： 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.
