Looking for an addition to our leaf removal equipment. We have looked at the Little Wonder hpv, bear cat, parker sweeper and the billy goat vq. These are among the largers walk behind vacs available. They range in price between 2-3k. The billy goat is the largest and has over 2000cfm at the nozzle. For leaf cleanup we use backpack blowers, 72" dixie chopper, 60" exmark wb w/ mulch kit and a kubota powered walker. On most lawns we blow first, mulch with the 60" Exmark wb, then bag with the walker. We wanted the billy goat to help the walker on pickup. Anyone used one or see one work?
