Makita GRU04Z 40V max XGT Brushless Cordless 17" High Torque String Trimmer (Tool Only) - GRU04Z
The 40V max XGT Brushless String Trimmer (GRU04) is engineered to provide the power equivalent to a 30cc string trimmer, but with lower noise, less maintenance, zero emissions, and no pull starts. It also has lower weight than a comparable gas-powered model. It has a 17” cutting swath and a rapid load bump and feed trimmer head for efficient trimming.
The String Trimmer has a variable speed trigger and 3-speed options (Low: 4,000 RPM, Medium: 4,600 High: 6,000 RPM) for power and run time management. In addition, users can set the Automatic Torque Drive Technology mode, which automatically shifts from 4,000-6,000 RPM for extended run time or added power. It also features a reverse function that quickly clears the trimmer head of entangled grass and weeds. The rapid load bump and feed trimmer head loads line in seconds with 3 easy steps: align, feed, and twist.
