If it has not already been suggested remove the cover plate for the PTO shaft and see if the retaining circlip is broken. A shot in the dark but this solved some similar problems on my 3320.
If circlip was broken would you not feel end play in the PTO shaft??? Does hyd fluid need drained to remove the pto plate?? Tks
