question about the universal joints on the shaft that runs between the PTO and the attachment (snowblower). there don't apprear to be any grease fittings so I'm working under the assumption it is sealed bearings. I have watched the shaft from the side before and at idle speed after engaging it appears to wobble very little, and seems to straigten to a more true angle when under more power. today, I glanced at the shaft running more from the top at idle and there seemed to be more of a wobble. I turned the tractor off and took the time to inspect further, and noticed it seems the actual joint on the end of the shaft that fits the tractor has some play in the actual joints; like it is a little loose. I don't think the joint on the attachment end has as much play, it is under a protective shield so a little hard to check as easily. so, question is - is some play normal, or should the joint be tight? It is a new to me tractor, so for all I know the shaft is 40 years old with who knows how many hours.
