The Honda HHT25SLTAT string trimmer is considered a heavy-duty model built for durability, and its four-cycle engine meets California's strict emissions requirements even without a carbon canister. The Honda GX engine is quieter, longer lasting, more fuel efficient and better for the environment than the two-cycle engines still used on quite a few gas trimmers. Those who want a less expensive fuel-efficient gas trimmer may want to consider the Hitachi CG22EASSLP (*Est. $190) , though its two-stroke engine isn't as powerful for cutting brush.
