The 80V max (40V max X2) XGT Brushless Brush Cutter (GRU05Z) is engineered to provide the power equivalent to a 40cc brush cutter, but with lower noise, less maintenance, zero emissions, and no pull starts. It also has lower weight than a comparable gas-powered brush cutter. It can deliver to 100 minutes of run time with two 40V XGT 4.0Ah batteries (batteries not included). The GRU05Z has a bike-handle design for improved grip and a more ergonomic working position and includes a 10 in. steel four-tooth brush cutter blade for cutting grasses, shrubs, and underwood. The Brush Cutter has a variable speed trigger and three speed settings (Low: 0-3, 500 RPM, Medium: 0-5, 000 High: 0-6, 400 RPM) for power and run time management. In addition, users can set the Automatic Torque Drive Technology mode, which automatically shifts from 3, 500-6, 400 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 steel drive shaft is engineered for reduced vibration. For added durability, it features IPX4 weather-resistant construction, and Extreme Protection Technology (XPT) engineered for improved dust and water resistance.
