The larger Lesco floating deck models seem to be a great value, especially in light of the larger HP motors and wider deckes for little more than the smaller units. Are they true dual hydros with drives that will hold up (as opposed to single hydro like the smaller Ferris)? The floating deck seems to indicate that it has rollers, rather than the "post and bushing" attachment that other floating decks use......any comments on this? Any comments on the machines in general? I need to buy in a day or 2 and don't have lotso ftime for research, thanks for any help.
