The WORX 10-Inch electric grass trimmer is the quick and lightweight solution for a manicured lawn. The dual-line feed features a unique auto-feed trimmer line system, so you"ll never have to tap or bump your trimmer to feed additional line. The auto-feed ensures you have the perfect amount of line at all times. The WORX trimmer line is made from a patented copolymer nylon resin and synthetic material. It is designed with an oval aerodynamic shape to increase trimming and edging life up to 25-Percent compared to normal use conditions. This patented resin line allows for the line to stretch and cushion on impact with hard surfaces. This unique trimmer"s balance allows it to stand upright on its own so no more dropping it to the ground when not in use or bending over to pick it up. Molded extension cord hooks allow the cord to be wrapped onto the trimmer and to be easily stored with the trimmer. No more tangled cords. The front auxiliary handle allows for more control while trimming.
