Designed for performance and comfortable use, the 15-Inch WORX 2-in-1 grass trimmer/edger is the perfect blend of comfort, control, and versatility. It utilizes a telescoping shaft and pivoting head to remove the backbreaking labor from trimming. A balanced design promotes natural body posture. This means maximum comfort and minimum fatigue, even during prolonged operation. The 2-in-1 design incorporates converting the grass trimmer to an in-line edger in seconds with no tools. Simply flip the head, rotate the handle, and the WORX becomes a fully functioning edger. The built-in support wheel helps you cut clean edges around sidewalks, driveways, and patios for a crisp, professional look. The WORX WG118 electric 2-in-1 trimmer/edger features a unique pivoting head that tilts to fit in tight spaces or sloped landscapes. The ratchet mechanism lets you tilt the cutter head from 0-90-Degrees without tools or special release buttons. And a foldable spacer guard prevents the cutting edge from damaging trees, furniture, walls or delicate landscaping. This trimmer/edger also has a unique auto-feed trimmer line system, so you"ll never have to tap your trimmer to feed additional line. The auto-feed ensures you have the perfect amount of line at all times. The trimmer/edger line is made from a patented copolymer nylon resin and synthetic material and designed with an oval aerodynamic shape allowing for the line to stretch and cushion on impact with hard surfaces.
