I need a new mower for the upcoming season! I can't decide between a Scag 61 Turf Tiger 35hp or a 60 or 66 Hustler Super Z 30hp with the new xr-7 decks. I have a Scag tiger cub now with a 48-inch deck. I just need something with a bigger deck. I am leaning towards the Hustler, but would the 66-inch be too big, a lot of scalping?? Help!
