Stihl RMA 370

Stihl RMA 370

Cordless lawn tools are no longer the laughably puny pieces of equipment they once were. Proof: The Stihl RMA 370, the first model to bring cordless mowing to the big leagues. Its 36-volt, 4.5-amp-hour battery lets it trim up to 3,200 square feet on a single charge. A 14 1/2-inch cutting deck gathers an impressive 10.5 gallons of clippings, and the entire package (with battery) weighs just over 30 pounds. It's quieter, too – 72 decibels versus a gas engine's typical 100. [Starts at $650; stihlusa.com]
