My boss bought a 52" Scag hydro w/b with the new "advantage" deck. I hate this mower. Love the way the new deck disperses clippings, but for some inexplicable reason Scag has made the chassis narrower (maybe so all decks can mount to same chassis?). Now the deck extends further past the wheels and the thing scalps EVERYTHING. We run all Scags with either 52 or 61" decks and have never had this problem before. This mower also has problems with right side drive mechanism (lagging or sticking). I am in the process of establishing my own landscape/lawncare company and will steer clear of Scag products, Go Exmark!!
