My Grandson was given an 850 Bolens. He said he couldn't get it to move and thought the belts were the problem. The belts are iffy, but also there is something was wrong with the clutch. I looked for a parts diagram online with minimal success. The one site I found wanted me to create an account. I'm hesitant to do that. Anyone have a recommendation for a source of parts and a parts diagram for these old Bolens?
