Hello, my 5 speed 8N won't go into gear. It sat over winter and would not go into gear when I tried to use it in spring. The PTO will engage and disengage with the clutch.With it running I can feel the tractor shake slightly when I shift from forward to reverse without using the clutch. I removed the oil fill plug on top of the differential and can see the center carrier move slightly when I shift from forward to reverse.
I tried locking the clutch pedal to the floor for a few days, removing the starter and confirming the throw out bearing on the trans shaft is not stuck.
Any ideas what the problem could be?
