Cord-Free String Trimmers
With no cord tethering you to an electrical outlet, a battery-powered trimmer will quickly neaten narrow strips of lawn in the quiet
Quieter than a gas-fueled model and with no cord tethering you to an electrical outlet, a battery-powered string trimmer—named for the thin plastic cord or line that cuts by spinning at high speed—is a worthy addition to your outdoor-tool arsenal this month, when grass growth really kicks in. These models will quickly neaten narrow strips of lawn along driveways, patios, and walkways, and they boast handy features to help you get the job done right, too.
The 18-volt battery gives you plenty of juice for jobs that can be finished in 30 minutes or less. Select 12 inches of line to conserve battery power, or drop down to 10 inches for a faster-spinning trimmer that offers serious slicing power. The battery is interchangeable with all the manufacturer's outdoor tools.

Swivel the head 90 degrees to turn this trimmer into a wheeled edger that cuts vertically instead of horizontally. Taller folks will appreciate its telescoping aluminum handle, which extends up to 14 inches so that stooping isn't necessary.
