Since we're into anything solar powered here, how would you like the sun to power your lawn mower?
Here are a couple of examples of "Solar Lawn Mowers" you can build yourself of have built for you. I understand they're less powerful but they don't pollute and are more quiet to operate. Let's face it-to everything there is an upside and a downside.
Why not make the sun work twice as hard for you this summer. It can grow you a beautiful lawn and mow you one also!
Solar Lawn Mower Examples:

All very interesting and admirable-You Go Boys!
