Makita-built Outer Rotor BL brushless motor direct-drive system provides high power and increased torque. Accepts industry standard spindles M10x1.25 LH for more convenience. Zero emissions and reduces maintenance; no need for gas or oil. Deliver up to 60 minutes of run time under load on the low speed setting using two 18 volt LXT 5.0Ah BL1850 batteries. 2-speed options (low; 5,000 rpm or high; 6,500 rpm) allows the operator to match speed to application. Bump and Feed trimmer head rotates the same counterclockwise direction as professional grade trimmers. Reverse (clockwise) rotation systemallows operator to quickly clear trimmer head of entangled grass and weeds. Constant speed control minimizes reduction in rotation speed under load. Direct-drive motor mounted directly on the trimmer head for increased efficiency and improved tool balance. Efficient BL Brushless motor is electronically controlled to optimize battery energy use for up to 50 percent longer run time per charge. BL brushless motor eliminates carbon brushes, enabling the BL motor to run cooler and more efficiently for longer life. 13-3/4" cutting swath for user convenience. Weighs only 9.9 lbs. with batteries for reduces operator fatigue. Extreme Protection Techno
