As anyone who's operated one knows, traditional gas-powered lawn tools are far from being "green." The Lehr Eco Trimmer & Blower ($180-$210) tackle this problem by running off 16.4 oz. Twist 'n Go propane canisters that allow for zero evaporative emission operation and zero-mess refueling. Other features of these eco friendly lawn tools include a four-stroke engine with a no choke/no priming start-up, a two-hour run time off a single canister, the lack of need for winterizing, and more cost-effective use and maintenance than your average tool. Well played.
