I like the bac -vac a lot only problem is needs more capacity(9 bushels) not enough, especially with leaves. I see you also have a 15 bushel bac-vac for one of your industrial mowers; can this be used on the Super Z and if not do you plan on increasing capacity on the Super Z vac. Since leaf season started the Super Z has been sitting almost 2 months now. We've been using our Lazer Z due to the larger capacity Ultra Vac. If you guys could increase the capacity and build a 60in walk behind I'd be running all Hustlers!
