I have 1985 Ford 1210 4x4 hydro and since owning it for the last 2 1/2 years there has been a rattle in the clutch area of the tractor at idle speed. That goes away with load on the driveline or pushing in the clutch. Did Ford ever have a TSB on this noise with a repair fix or should I just live with it and call it a normal noise on this series of compact tractors.
