Use a reel mower.

If you have a reasonable sized lawn, start using a reel mover. This is what Grandpa would have used and they are quite effective. Needs no gas. No maintenance except a little oil now and again and a blade sharpening every year or two. They are also virtually silent – so no annoying the neighbors if you want to cut your grass early in the morning and late at night. Also, you spend less money on it & get a little exercise.
