Exhaust outlet has burned the bottom of the left side panel. Hot exhaust gasses are blowing onto the plastic panel. The muffler outlet needs to be repositioned to direct gasses away from the tractor! Also, the parking brake does not engage. This tractor only has 12 hours on it! I am hoping john deere stands behind these issues. This is my third john deere I have owned, and the first one I have had problems with.
