Product details

Cordless Grass Trimmer GRT 18V-40

The GRT 18V-40 Professional is a cordless grass trimmer featuring a powerful, brushless 600 W motor that reaches a maximum speed of 5300 RPM in less than one second. Its well-balanced design and a 360° adjustable D-handle reduce strain and fatigue during use. A dual-function handle allows for a seamless transition from trimming to edging. The electronic speed control automatically maintains a constant speed under varying conditions. The throttle switch enables adjustment of the motor speed to optimize runtime and noise levels according to the specific working conditions.

The Bosch Anti-Tangle feature ensures smoother trimming progress by preventing long grass or weeds from wrapping around the motor shaft and blocking the device. With a cutting diameter of 40 cm, large tasks can be completed quickly, and the robust Pro-Tap spool ensures fast cutting progress. The EasyWind spool allows for quick line changes without opening the spool. An integrated plant protection guard provides a clean finish along lawn edges and walls, shielding tree trunks and plants from the rotating line.

Thanks to its low noise level, the GRT 18V-40 Professional is also suitable for use in residential areas and other noise-sensitive environments. The GRT 18V-40 Professional is the perfect solution for trimming grass and weeds in larger areas. It is compatible with the Bosch Professional 18V System and the cross-brand AMPShare battery alliance. Equipped with a durable aluminum motor housing, it offers practical storage solutions and a comfortable shoulder strap.
