Powered by a recoil start Briggs & Stratton 850 Pro Series engine, the rear wheel drive on the self-propelled MV601SPDS outdoor vacuum makes operation easy, even in a hilly environment. The 74cm (29") wide gobbler door is adjustable from the operator's position for easy switching between hard surface, turf or hose applications. It features a powerful six-blade impeller for maximum suction and debris reduction.
