There have been a few of them around here in the past two years or so, but none that were terribly successful. Moving the lawn mower is not the problem. Keeping the blade moving under heavy load as it cuts through grass is. This is why even small gas mowers have 5hp-15hp Briggs & Straton motors on them. Good luck.
