An elderly friend of mine asked me if I was interested in an electric mower that he had, I went and came home with this
After half an hour he pulled out this
He had it on charge for a while and the battery came good, not bad for three years of sitting. It was a new battery when he stopped using it. I tested it out briefly when I got home and it all works :-). Will give it a tidy up and look into getting the reel ground etc.
