Cutter K 770 SmartGuard

Product description
Husqvarna K 770 SmartGuard is a petrol power cutter designed for professional cutting tasks. Equipped with SmartGuard, an extended blade guard that reduces the likelihood of accidents and kickback by emphasising correct technique and the proper cutting zone. The semi-automatic SmartTension™ system provides optimal belt tension for efficient power transmission and extended belt life. The machine combines low weight, a high power-to-weight ratio, easy starting and very low handle vibrations to reduce operator fatigue and support long operation cycles.
