First I want to thank everyone that help with the Starter/Generator problems I had a few weeks ago. Everything is working good. Now I have a new problem. The left front wheel froze up, I have a 48" mower it and was cutting grass when all at once the left front wheel wouldn't turn. When I finally got the wheel off the axle there were no bushings in it and there is a key way in the hub. Why would there be a keyway in the hu?. My thinking that it has been modified by PO. My thoughts that I could bore out the hub to either use bronze busings or a roller bearing. I don't use this mower a lot but I can cut grass with it that I wouldn't take my new Cub Cadet. Bearings or bushing?
Either way I would put in grease fittings.

Thanks,
Ted
