Shag,
Sell your tractor and don’t look back. Way too many hassles already and lack of confidence. A lift arm that you can raise high enough to break your fender is BS engineering. No excuses for that though some try to make them. No wonder you are having so many problems, pigdin engineering. Then go buy yourself a good old Ford from the ‘60s or ‘70s and will it to your grandkids. The newer tractors all have confounded electronic this and that which probably will be a source of headaches down the road, especially when the mice figure out the wiring is wrapped in yummy soy insulation. Good ole American steel, and only points, rotor cap, and condenser to worry about for electrics. Something wears out, pull it apart with your SAE wrenches and fix it yourself.
