The Worx Nitro 20V 13” Cordless String Trimmer delivers exceptional performance to support a variety of grass trimming tasks—such as cleaning up sidewalk, driveway, and retaining wall areas. Designed to elevate trimming capabilities, the WG173 is 2X more efficient than previous GT grass trimmers from Worx. This lawn trimmer also saves time with a dual-line 13" cutting diameter, offering a 3X larger trimming area than the GT series. The 20V 13" grass trimmer features a high-efficiency brushless motor that runs 50% longer, is 25% more powerful, and delivers a 10X longer life than standard brushed motors. Used with the Power Share PRO 4.0Ah battery, you'll enjoy even more enhanced performance, as this battery is designed to stay cooler, resist heat and impact damage, and optimize power output to increase runtime by as much as 30% longer than the GT model. For even more convenience, this same battery powers over 140 20V, 40V, and 80V lifestyle, garden, and power tools in the Power Share family. This 3-in-1 edger lawn tool gives you the ability to quickly switch between trimmer, edger, and mini-mower modes, so you can get more done in the yard with a single tool. Rely on the durable wheels to maximize maneuverability and achieve perfect, crisp lines when using the lawn trimmer in edger mode.

When your line runs out, you can easily reload with the (WA0007) Worx Replacement Trimmer Line Spool—it's pre-wound for quick loading. This cordless edge trimmer is lightweight at only 6.62 lbs. (w/ battery). Plus, it's packed with adaptable features that enhance control and boost user comfort. For example, the telescoping rotating shaft adjusts to fit the height and positioning of the user, while the adjustable auxiliary handle gives your hands more flexibility. When you’re working on hills or around hard-to-reach areas, the 90° pivoting head adapts to maintain precision cuts.
