The WORX Cordless 20-Volt LithiumPower 2-in1 Trimmer/Edger is a powerful, lightweight, and easy to use yard and garden machine. Convert the trimmer easily to an edger and vise-versa in seconds with no tools. The specially-designed adjustable handle and shaft can accommodate varying working heights for maximum comfort and control. Save time and effort with an easy safety start trigger — no more pull starting; no more gas/oil mixes; no more exhaust smells; and no tangled cords. Typical trimmer batteries may need to be recharged before using them even if it was charged after the last use. With the LithiumPower battery technology, it resists self-discharge for much longer periods of time, and it has the ability to perform a quick partial charge without worrying about “memory effect” damaging your battery. The LithiumPower battery is lighter in weight and more compact. The rubberized twin-set wheels roll easily to guide along when edging to help maneuver through the edging process. To protect flowers and ornamental objects, there is a retractable flower guard to keep the trim line at just the right distance from valued objects in landscaping and yard. An automatic single line feed means no bumping to advance the line. The trimmer line features a long-lasting DNA-2 copolymer nylon resin and synthetic design making it more pliable against hard objects or surfaces for less breakage. The WORX two-in-one trimmer and edger is the ultimate yard, lawn, and mower accessory for the perfectly manicured space.
