Hedge trimmers: powered hedge trimmers take some of the elbow grease out of keeping shrubs in shape.(Home and Yard: Reap the Savings)(Buyers guide)

But using them can still be hard work, since you're holding these machines aloft for extended periods. That makes a trimmer's weight, balance, and vibration as important as its performance. Safety is also important given the number of injuries that occur each year. Fortunately, you'll find several models that blend comfort, capable cutting, and features that help protect you while you work.

WHAT'S AVAILABLE

Black & Decker and Craftsman (Sears) dominate the corded and cordless-electric market; Craftsman also sells gas-powered models. Other brands include Echo, Homelite, Husqvarna, Little Wonder, Remington, Ryobi, Stihl, and Weed Eater.

Corded electrics. Plug-in trimmers account for the most sales, since they're relatively light, quiet, and inexpensive, start with push-button ease, produce no exhaust emissions, and require little maintenance. The best also perform comparably to gasoline-powered models. But you'll have to work within range of a power outlet and be sure not to cut the cord. Price: $30 to $100.

Cordless electrics. Battery-powered trimmers combine the mobility of gas models with the convenience, clean running, and easy maintenance of plug-ins, courtesy of an onboard battery (14.4 volt to 24 volt). But they offer relatively little power and no more than about 45 minutes' run time per charge. They can also cost as much as gas-powered models. Price: $70 to $120.

Gasoline-powered trimmers. Landscapers favor these for their power and mobility. But gas models typically weigh more than electrics, and their two-stroke engines require fuel mixing, pull-starting, maintenance. Gas trimmers can also be expensive. Price: $130 to $450.
