Now that lawn mowing is history for another year (in northern climes, at least), I thought you might enjoy American-Lawns.com's fascinating look at lawn care history in this article on the evolution of lawn mowers.... They also provide a lawn care tip that could be useful for your next lawn mower purchase. Namely, battery-powered mowers are "becoming practical.... Prices are comparable to a high-end gasoline powered mower." And they're pollution-free. Please consult my consumer product review on battery-operated lawn mowers for more information on this landscaping equipment.
