This weekend I had the opportunity for a little maintenance, that by chance happened to include the operator station platform removal. As I was visually inspecting everything, I was surprised to find that a small retaining clip (11/red oval) had some how came out of the end of the lift pin(22) . The pin was bound in the hole, and fortunately nothing else seems to have been damaged nor was the hole egged out. I consider my self fortunate to have accidentally found it. THIS is why we call it preventive maintenance, or as my wife says, "playing"
