how to replace bearing on a 111 john deere?

Try looking on the john deere website for a parts diagram. I think that there is a bolt down in the center of the pulley. Get that out. A small metal key might fall out. Don't lose it! Oh, and don't forget to take all belts off the pulley before you loosen it. Then take the pulley off. If it is stuck on, tap on it with a rubber hammer. I don't know much more than that, as I haven't taken them apart further than that. Hope this helps! We have 3 of these mowers, 2 geardrive 1 hydrostatic.
