It seems that my running mower is not charging the battery. There is no output from the magneto. When the battery gets low enough the first thing to quit is the PTO, if I keep running the engine will quit and won't do anything until I charge the battery. With a full charge on the battery I can mow until again the battery gets too low to keep things running. Don't know how to fix the magneto thing but at least I know the problem and don't have to junk the mower because an electric is an expensive proud thing.
