A month ago I bought a Black & Decker Cordless Electric lawn mower, not expecting to mow my whole yard but at least reduce my fuel consumption and the horrible gasoline smells in my garage. I am happy to report these mowers do work and have saved me over a gallon of fuel already.
I wrote a review about it and hope it will encourage you to get one as well!
