Looking for a commercial zero turn but am wary about buying a used one with 500+ hours. Budget is around $5-6k. I will be mowing about 3 acres of totally flat ground with minimal trees/obstacles. The three I have checked so far are: Near mint 2005 Ferris IS2000z 61" with 92 hours and 25HP Kawasaki. It was used by a hang-glider club to mow an airstrip. I could get this for $6200. New 2007 (yes that is NEW 2007) Gravely XDZ152 52" deck with 23HP Kawasaki - $6000. New 2009 Cub Cadet Enforcer 54" deck with 23HP Kohler Command - $5800. Lastly, does anyone know about the new Cub Cadet zero turns with the steering wheels (Z-Force S model line)? I saw one at the dealer with a 60" deck and 26HP Kawasaki for $5000. The deck is fabricated (although not as beefy as the Tank model) compared to the stamped steel version on the old Z-force model. The only other thing I noticed was the front wheel spindles were cast iron but they did have a grease fitting. Any suggestion would be greatly appreciated!
