Full of quality-of-life features and easy to use, the 15 in. - 5.5-Amp Electric Grass Trimmer/Edger from Worx leaves lawns looking sharp and users free of fatigue. It's only 6 lbs., so almost anyone can pick it up and help with the yard work. and with an adjustable handle and telescoping shaft, it can be made to fit landscape artists of all sizes. The automatic feed dual-line system dispenses the right amount of string when you need it, out of 2 exit points, doubling the coverage compared to some other trimmers. and let's talk about that line for a second. It's our patented DoubleHelix DNALINE2, with 100 lbs. of tensile strength. It's designed to withstand breakage and the aerodynamic oval shape cuts through the air and the grass, reducing drag. The 0.065 in. Dia is the same gauge that professional landscaping crews use on their grass trimmers, so you'll get professional-grade results. This model has a 15 in. cutting diameter. That's large enough to make smooth, even passes, but narrow enough so that you can still get in-between trees and shrubs without much problem. But the real reason this string trimmer is such a value is because it's also an edger. Just rotate the shaft and the head turns on its side so that you can cut crisp, long lines along driveways and curbs.
