I am searching for a commercial mower for the 2013 mowing season. Unfortunately, I don't have a lot of money so buying a new mower is out of the picture. I have a budget of about $4,000 to $5,000. I have looked at a lot of different mowers and I am having a hard time deciding. I do need a zero turn, with a 60" deck. What kind of mower would be best in that price range? I have looked at some Kubota's and John Deere's simply because I have a dealer for both close to me so the parts would be easy to get. In that price range, I can get a John Deere with about 1,500 hours on it or a diesel Kubota with about 1,700 to 2,000 hours on it. Suggestions?
