I've been using the Cub Cadet Zero Turn 364 which was fine but the stamped deck has finally rusted through dropping my middle blade and spindle. The mower itself only has 225 hours so I am trying to determine the best resolution......fix or buy? I really want to step up to a commercial mower with a welded steel deck and have been looking at new and used everything from Ferris, Bobcat, Dixie Chopper, Toro, Husquvarna, Exmark, Bad Boy, Dixon, etc. I'd really like to find a used, low hour machine around 50" but would go larger or smaller to get a better deal. Craigslist seems to be the best place to look but I haven't yet found the right deal. I'm looking to spend up to $5000 which is less than the MSRP of most of the these brands commercial series. Any input is appreciated.
