Thanks for all the replys. I'll have a little time this evening to check into it. I have a bad feeling it might be the bearing. I do remember hearing a higher pitched chatter when sitting at idle while changing the angel on the plow.
Yesterday was the first time I've spent much time with this tractor.
Usually I use my Simplicity, but loaned it to a buddy with a pregnant wife so he doesnt get stuck in the driveway during the moment of truth. :)
No good deed goes unpunished. I favor Bolens and AC/Simplicites too. Good Luck, Rick
