I noticed a loud grinding noise like a bad bearing inside the rear end at the pto shaft. It would only happen when the snowblower was lowered all the way down. If I raised it so the pto shaft was straight it would go away. I thought it was the snowblower at first, but it definitely was coming from inside the rear end.. Can the pto shaft bearings be replaced from the back of the tractor or does it need to be split. Any info would be appreciated. Thanks Martin [Reply]   [No Email]

I hope this helps Andy. [Reply]  [No Email]

IIRC neighbour changed PTO bearing on his 4210 from the rear. Before tearing it apart, I would check the bearing by using an old broom handle held against the bearing cover and the other end against your ear and listen for the squealing noise. BECAREFUL NOT to get tangled up in the PTO. JimB [Reply]  [No Email]
