Not some kind of industrial petrol strimmer which terrifies our small children, requires goggles for safety and needs to be strapped to you because it's so heavy?
Not a massive pull start mower which is so heavy it requires two people to lift it out of the shed?
Perhaps, if I had a lawn mower that was easier to use, I wouldn't have to wait for the stars to align correctly; for it not to be raining, dh to be at home, not busy and "in the mood" to cut the grass. There would also be much less nagging, because I could just do it myself. Seems a no brainer to me.
