Got it narrowed down to these 2 tractors. When does the turbo on the MX5800 shine & when would I be better staying w/ a MX5200? Work will consist of a steep mountain property - clearing trees, downed debris, moving rocks, bush hogging a little, property is steep & 1,500' elevation. Other property is 65 acres of farmland 300' elevation that I'll be bush hogging & clearing trails. Will eventually add a grapple to the front for brush & logs but prob. not for a year or two.
