I posted about a possible problem with my mid mower last week. It ended up being gear failure in the mid-pto, taking out 3 gears. After I working on it, I found that the rear bearing in the mid-pto housing is not the correct bearing. The mid-pto shaft is much smaller and there was a lot of slop. The service manager at the dealership I purchased the tractor from agrees that the wrong bearing was installed at the factory. I bought the tractor, a JD 4310 hydro, new. It only has 405 hours, but is out of warranty (I have had it 6 or 7 years, boy time flies), so the service manager is not sure whether John Deere will do anything to cover this. I am keeping my fingers crossed, as this is turning out to be an expensive repair.
