About This Item

The Worx Nitro 20V 13” Cordless String Trimmer delivers pro-grade performance to support a variety of grass trimming tasks—such as cleaning up sidewalk, driveway, and retaining wall areas. And with the ability to switch between trimmer, edger, and mini-mower modes, you can get more done in the yard with a single tool. The high-efficiency brushless motor runs 50% longer, is 25% more powerful, and delivers a 10X longer life than trimmers with a standard brush motor. With this added power, the 13” dual-exit cutting head makes trimming effortless—even in dense, overgrown areas. Extend trimming line with ease and efficiency using the intuitive push-button command feed system. While this cordless string trimmer remains comfortably lightweight, it is packed with flexible features that enhance control and reduce user fatigue. For example, the telescoping rotating shaft adjusts to fit the height and positioning of the user, while the adjustable auxiliary handle makes for more flexible operability. As part of the Power Share platform, it uses the same batteries as every other tool, outdoor power and lifestyle product in that family. When you’re working on hills or around hard-to-reach areas, the 90° pivoting head adapts to maintain precision cuts. The trimmer also comes equipped with durable edging wheels that maximize maneuverability and enable clear, crisp lines along grassy edges.

Changing the game of lawn care, one yard at a time, the GT Revolution is 3 lawn manicuring tools in one. Converts almost instantly from a trimmer, to an in-line wheeled edger, to a mini-mower, so you get a professional-looking lawn that’s easier to maintain and costs less time and money. This is so much more than a weed-eater. It’s a Revolution. At less than 6 lbs, and with a telescoping shaft, 7 handle, and 6 rotating head positions, almost anyone can comfortably use the Revolution. The shaft is a full foot longer than the original GT, and the grips are ergonomically designed to give the user a firm handle on each of the three functions. And when you want to switch from trimmer to edger or mini-mower, it’s just a push of a button and a turn of the head. No tools needed. It’s powerful, too! Spinning at 7600 revs/min and running on the same 20V 4.0 Ah Powershare battery that powers our chainsaws, the GT makes nice, clean cuts. The patented Command Feed system gives you fresh line whenever you need it—no bumping or auto-feed. With an extra spool holder right on the handle, if you do run out of line in the field, you can just pop in your extra spool without a trip back to the shed.
