I have two acres but probably only a acre and a half that I cut. For years, I used a Craftsman riding mower, 23 hp, 42 inch deck. It did the job without any problems. Now I have a Gravely zero turn with a 52 inch deck. I love it. Believe it or not, before I got the Craftsman I used a 30 inch Snapper rear engine. So, I would say, find the one that you like and go with it.
