The Worx Nitro 40V 15” Cordless String Trimmer offers pro-grade performance to support a variety of grass trimming tasks—such as cleaning up sidewalk, driveway, and retaining wall areas. 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 15” dual-exit cutting head makes trimming effortless—even in dense, overgrown areas. The 15” cutting diameter optimizes coverage to help save time and effort on expansive landscaping tasks. Use the bump-feed system to advance trimmer line with a simple tap on the ground, giving you tighter control over how much line you use. Find the right speed for your specific trimming task using the variable speed control, conveniently located on the handle for easy adjustment. For lighter tasks, switch to ECO mode to conserve battery power and extend run time. And with the easy-read charge level indicator, you can quickly see how much battery power is left and determine when it’s time to recharge. The 40V 15” String Trimmer uses an easy-load spool head—a new addition to the Worx product line that stays on the tool for simpler trimmer line replacement. This spool fits standard-sized .095” trimmer line, which can be purchased directly through Worx. Includes: 40V 15” Cordless String Trimmer, (2) 20V 4.0Ah Power Share PRO batteries, (1) 4A dual-port quick charger.
