With the price of gas these days, it's no wonder people are skittish when it comes to mowing lawns. What's more, gas-powered mowers have been shown to pollute up to 7 times as much as vehicles. Sure, you could go get a manual mower and get some exercise, but why do that when you can convert your gas-powered mower into an electric one? This modification takes you through three steps to do just that, including: removing the engine and installing an electric replacement, converting the engine to one powered by solar panels, and installing the solar panel. Expect conversion costs to run around $1,500. Of course, you could always just buy a Huskvarna and skip all this tomfoolery.
