I still have bad memories of forgetting I am using a machine that is connected to lethal 240 volts and running over the all too flimsy lead. Lots of sparks and threw the trip in the meter box, but luckily no shock. The thought of just two thin pieces of insulation between me and death is enough to keep me well away from corded electric mowers. I've had enough near misses with the 240 volt hedge trimmer.
