I am starting to research ZTR mowers for residential use and wanted to get opinions from the experts. I have a 4 acre lot with lots of trees (don't mow it all). Because of the trees, I think I am going to stick with a 52/54 inch deck. I have read up on the JD M655 (25hp/54" deck), Scag Tiger Cub (23hp/52" deck) and ExmarkLazer Z (20hp/52" deck). What are your opinions/recomendatins on these three mowers. I live in a small town that only has a deere and Scag dealer. The Exmark dealer is 1 hour away. How much should I let this influence my decision? Thank you.
