I've been wracking my brain trying to remember who was good with knotters around here. There were two guys who knew them inside and out,but they're dead now. I did remember one who's still alive. I don't know how much he remembers anymore,but a neighbor used to do a fair amount of custom baling and had an old IH 46 tuned to perfection. Bill Jeffery. He lives right here on Holland Road about a half mile south of County Farm. Somebody had said a while back that he was having trouble with his eyes,but he's still driving and isn't wearing glasses. He'd be the only one I'd know who might have any shot at knowing.
Did you ever check the shims on the shaft to make sure it wasn't to one side farther that it should be?
