Thanks to the patented gear drive, torque and power remain consistently high, even in tall or wet grass. An adjustable second handle and a telescopic shaft provide additional comfort and improved control. The cutting head can be easily switched from trimming to edging, and the guide rail along with automatic vertical speed reduction ensures a perfect lawn edge.
