At home, where we have an acre of grass and a little Toro tractor, he does it as a ride-on deal. Fortunately for us he mows willingly and without pay, despite having to drive through the curtains of wee green worms dangling from the fruit trees. I think he mostly likes driving.
In town, though, he's using push mowers and mowing other people's lawns for money. As usual he needed a bit of a nudge to take on this new role, but he's now happily into it and is enjoying the income and the sense of responsibility.
