So the amount the now your lawn is just as bad as all the driving you do on the week end

If you drive a diesel, it's far worse. Nox emissions are about 0.125g/km for a modern pickup. That's 12.5 per 100km of driving vs 1.86 per hour for the mower. So ban diesel pickups if you are that concerned about Nox. And if you are actually concerned, ban mods and fine them heavily, because they emit far more. Even "clean diesels' emit far more Nox than a mower.
