You can do one of two things with a grass lawn.  First, you can get rid of it and save water and fuel.  Or, second, you can minimize the lawn surface and avoid fuels when maintaining it.  If the latter is your approach, this new Helix HX1000 from family-owned EcoMower could come in handy.  The light, 21-pound reel mower takes a 16″ path with heat-treated, carbon steel blades designed to cut without much upkeep.  Maintain the quiet, get some exercise, and ditch carbon-based fuels with this reel mower selling from $220.
