I figured it was time I looked into the charging system on the tractor. It had a dead 6 volt battery in the compartment when I bought it so I was pretty certain the electrical system wasn't too far out of order. I pulled the generator and regulator off the tractor and took them to the bench. The generator didn't look too terribly bad in where the three brushes reside, but two of the three brush holders were stuck. A little oil freed them up. This first photo below shows the side with one brush. It's pretty clean in there.
