About 6 years ago, I bought a new Mustang GT. When I got under it to do the first oil change, I found the lower bolt holding in the starter was hanging on by just a couple of threads. Lucky I caught it and lucky you caught yours as well. Now to get my brand new tractor up on ramps and take a peek.Unfortunately it’s a very common thing. Sad but these tractors should come with a bottle of lock-tight. Just because they put a marker to the bolt head doesn’t mean the torque gun was up to snuff or set correctly. And according to my tractor they don’t recertify.
