Makita 40V Max XGT 17 inches String Trimmer Kit - GRU03M1 

The 40V max XGT Brushless String Trimmer (GRU03) 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 trimer head for efficient trimming. It also has a brush cutter debris shield and loop handle equipped with a barrier bar for compatibility with brush cutter blades.

The String Trimmer has a variable speed trigger and three speed settings (4,600 / 5,500 / 7,000 RPM) for power and run time management. In addition, users can set the Automatic Torque Drive Technology mode, which automatically shifts from 4,600 RPM to 7,000 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.

• Reverse Function Use: Use the reverse rotation function to clear tangled grass or weeds from the trimmer head quickly and reduce downtime.

• Store Properly: Store the trimmer off the ground and away from moisture or extreme temperatures to prevent corrosion and preserve components long‑term.
