I wanted to purchase a scag wildcat 52" zero turn, but I am not for sure, because this will be my first zero turn. I have a 48" scag hydro walk behind, but the cut wasn't that good, I had to go over the cut twice every time last year. I didn't have many mechanical problems with the scag, but I need to know what is the best commercial riders out there, name four or five if you could. I wouldn't mind getting a john deere, gravely, or toro either, but I need some opinions. What are your top five and why?
