thanks for sharing this information Ray on battery opreated equipment. As a kid we had a Sunbeam electric mower run of course off an extension cord and we mowed a good bit of property with it. However if any of you have used such equipment with the electric cord you would remember many repairs to the cord with lots of black tape. I'll be looking at this new Craftsman battery mower. Lee
