Worx Nitro tools are built for professional-level performance. The high-efficiency brushless motor runs longer and delivers more power than a typical brushed motor. You'll get gas-like performance without the fumes, maintenance and extra cost thanks to dual Power Share batteries, which increase trimming time and power and can be used with over 75 other Worx tools. A 15" dual-exit cutting head provides powerful, efficient trimming capability to easily cut dense grass along sidewalks, driveways, walls and more.
