I never mentioned sealed bearings and none of my numerous cubs even have them. As far as I know, they did not come with sealed bearings. I know the later models have a grease fitting on the inner side and I assume it is supposed to be lubed now an then.
Call me old school but repacking and servicing wheel bearings on cars was one of the very 1st thinks I learned as a kid messing with cars back in the day. Of course they were a different type of bearing altogether.
Do they even make a sealed bearing with an outside lip to keep them from sliding into the hub of a Cub wheel?
I looked at a "restored" 122 last week at an auction house just for the hell of it. New tires, new paint, nice seat that was sitting on 3 layers of 2X10. I could turn the steering wheel about 1/2 turn before any movement was seen at the wheels. Knelt down beside the front wheels and grabbed hold and was able to move the front of the tractor back and forth nearly 4 inches. This is why we need to maintain these machines on order to keep them in good working order. Imagine trying to mow a straight line with that rig.
BTW, I learned later it gaveled down at $350.
