Looking to save a little energy this summer? Buy a Push Reel Lawn Mower, you know those mowers that don't have an engine, and use your own power to mow the lawn. These mowers have come a long way over the years and are now much easier to push than older reel push lawn mowers.
These mowers can be hard to find, since your local hardware store would probably rather have you buy more expensive mowers, but you can buy them online.
