An improved power lawn rake has a rotor provided with a plurality of ground-engaging spring tines. The dead leaves and other debris are carried by the rotor along the curved forward wall of a deflector box, and are discharged between the deflector box and a front channel and into a molded bin. The bin is removably mounted on respective side housings of the main frame of the power lawn rake. Ground-engaging forward wheels are vertically adjustable on brackets mounted on the front channel. The wheels are nested within externally-accessible recesses formed in the bin. A driving motor is cantilever mounted on one of the side housings of the frame for driving the rotor. The drive is through gearing (in a gear case secured to the motor housing) and through a belt and pulley arrangement accessible through a cover plate removably secured to the side housing. The motor carries a fan for drawing motor cooling air in through inlet openings in the other side housing and discharging the same around a shroud and through air exhaust openings formed in the one side housing. A first U-shaped handle assembly may be pivoted forwardly of the frame, and a second U-shaped handle assembly may be pivoted over the first handle assembly, thereby facilitating convenient storage of the machine. The second handle assembly has a bight portion forming a hand grip and including a pair of complementary mating halves. A switch and an externally-accessible switch actuator are trapped between the mating halves of the hand grip.
