Has anyone used duallies on a JD 3320 size tractor for mowing? I have a quote for $3,500 for new duals. I am looking for more flotation on mowing wet woods trails. The 5093 is rutting badly, the 333D tracked skid steer is rutting, and the 3320 is rutting some. The rubber tracked JD Gator does not rut at all.
