That is why I like lawn mowers that you can drive. The are not as exhausting and can get the job done faster. It really depends on where you live. I live on a farm so we use a drivable mower. If you live in the city or the like you use a push mower.
God, I know. Push Mowing has to be the bane of my existence, like, holy crap. I'd rather do 100 push-ups (which I can't even get to 10) then to Push Now.
