M18 FUEL™ String Trimmer (Tool Only)

The M18 FUEL™ String Trimmer has the power to clear thick brush, reaches full throttle in under 1 second, and provides up to 1 hour of run-time per charge. Designed to meet landscape maintenance professional needs, the motor is positioned in the rear of the trimmer to provide the best combination of power, balance, and maneuverability. The trimmer features high and low speed settings with a variable speed trigger. High provides the power to clear thick brush, and low maximizes run-time while having plenty of power for grass trimming. The 16” cutting swath trims more grass in a single pass, increasing productivity. The full sized head holds more line and has a metal reinforced bump knob for longer life. The M18 FUEL™ String Trimmer is fully compatible with 150+ solutions on the M18™ system.
