From a strictly engineering perspective I see this contraption as less than likely to be very successful. It needs to have the angle between the bike and mower more like 30-40 degrees instead of nearly straight up and down as this one is.
Then again, who knows it might work as is, it just dudn look too promising as too much weight will be forced downwards instead of forwards
