By using a bi-directional, higher-capacity motor for over-the-brush or dustpan-type sweeping, the Big Dawg Collector Sweeper uses only a single motor on all sizes for systems up to 25 gpm and 3,500 psi. Features include quick-change core; durable front beak with motor guards; sight gauge; and replaceable, bolt-on cutting edge. Sweeping widths range from 62, 74 and 84 inches.
