I was in a yard last week and my right wheel locked up. Thought it was the hydro pump. Couldnt get it to move even after I unlocked the pumps. My parking break came apart and jammed my wheel. Had to have it towed out of the yard. Should get back soon. It is a Toro 3000 with 170 hours on it. Kind of disappointed something happened so soon on it. Good thing I have a back up.
