K 770

The Husqvarna K 770 is a powerful all-round power cutter with features that make it one of the best power cutters on the market. Equipped with semi-automatic SmartTension™ system allows for optimal power transmission, minimum wear and maximum belt life. The light weight, outstanding power-to-weight ratio, the reliable start and exceptionally low vibrations mean less strain and maximized productivity. Suitable for road work and easy to cut in a straight or curved track or close to sidewalk when used with KV7 trolley.

Easy and optimal belt tensioning
The semi-automatic Smart Tension minimizes the risk of under- and over tensioning.
Light and powerful
A light, compact and powerful machine with superior power-to-weight ratio.
Heavy-duty cutting arm
The new-designed cast magnesium crankcase has a three-bolt joint to attach the cutting head, enabling higher torsional rigidity than the previous two-bolt solution.
Long service intervals
A strong Poly-V belt combined with our maintenance-free starter DuraStarter™ and efficient filter-system Active Air Filtration™ ensures long service intervals.
Easy to start
The unique design of the carburettor, cylinder and digital ignition system, together with air purge and decompression valve ensure an easy start.
Optimized engine performance
Optimised engine performance through efficient cylinder design, digital ignition system and X-Torq engine technology.
Less slurry and low water consumption
Excellent dust control with our wet cutting kit. A progressive water valve for exact adjustment of the water volume to efficiently bind the dust and reduce slurry.
Easy to change blade guard position
The light magnesium blade guard facilitates cutting, thanks to its step-less adjustment.
Easy to start
The unique design of the carburettor, cylinder and digital ignition system, together with air purge and decompression valve ensure an easy start.
Fits multiple blade bushings
Blades with 20mm and 25.4mm bore can be fitted thanks to the reversible blade bushing.
