why do i keep seeing all the mower co's making and wasting their time developing DECK/BELT mounted blowers/vacs for grass collection? The only co. who finally had the sense to wise up and actually make a clutch drive off the engine vac system is snapper.don't they realize that the deck systems are a pain in the rear? with all the money spent in development of these high dollar Z machines they go back to the belt/deck blower configuration.what gives? i want a machine that at the flick of a switch or a turn of a lever i can turn on/off a vac unit.i don't want the hassle of having to manually put on a belt drive setup only for the few lawns i collect.anyone else agree? maybe if enough people got together and wrote their rep or complained loud enough at one of these expos they'd listen.
