Lawn mowers: practically any mower cuts grass. But you'll get better results if you choose one based on your lawn size, mowing preferences, and budget.(Home & Yard: More Value for Less)(Buyers guide)

Mowing options range from $100 manual-reel mowers to tractors that cost $4,000 or more. If you have a small, level yard, a manual-reel or electric walk-behind mower is probably fine. Gasoline-powered walk-behind mowers are appropriate for most lawns up to about a half-acre. For larger lawns, you might want the ease and speed of a lawn tractor.

Compared with cars, gasoline-powered lawn mowers produce a disproportionate amount of air pollution. While mowers are run far less than cars, federal emissions rules have made today's gas-powered mowers cleaner than older ones--something to consider if you're using an older mower.

WHAT'S AVAILABLE

Manual-reel mowers are still made by only a few companies. Major brands of electric mowers include Black & Decker and Craftsman (Sears)--a brand that also sells the most gasoline-powered walk-behind mowers.

Other less-expensive, mass-market brands include Poulan, Weed Eater, Yard Machines, and Yard-Man. Pricier brands traditionally sold at outdoor power-equipment dealers include Ariens, Bolens, Honda, Husqvarna, John Deere, Lawn-Boy, Poulan, Snapper, Toro, Troy-Bilt, and Yard Machines. Several of those brands are now available at large retailers, including Home Depot and Lowe's.
