An improved mounting means is provided for the driven pulley of a power lawn rake. The driven pulley has a through axial bore. The rotor shaft is received in the bore and extends therethrough. A central tubular hub is formed on the inner face of the driven pulley and has a pair of diametrically-opposed openings formed therein. A transverse pin is carried by the rotor shaft and has radially-projecting end portions received in the openings in the hub, thereby keying the driven pulley to the rotor shaft. A self-locking retaining ring is received over the extending portion of the rotor shaft and resiliently bears against the outer face of the driven pulley, thereby retaining the pulley on the rotor shaft.
