Light and powerful
The K770 is a light, compact and powerful machine with superior power-to-weight ratio.

High power with less fuel
Built-in automatic filter compensation SmartCarb™ maintains high power and lowers fuel consumption.

Optimised engine performance
Through efficient cylinder design, digital ignition system and Husqvarna X-Torq® engine technology which reduces emissions by up to 60% and increases fuel efficiency by up to 20%.

Digital ignition with optimised timing
Provides a powerful spark with optimised timing, enabling easy start and efficient combustion.

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.

Exceptionally low vibrations
Vibrations below 2.5m/s² in the cutter handles for improved operator comfort and longer periods of safe use.

Heavy-duty cutting arm
The cast magnesium crankcase of the K770 has a three-bolt joint to attach the cutting head, enabling higher torsional rigidity than the previous two-bolt design solution.

Easy to change blade guard position
The light magnesium blade guard of the K770 is quick and easy to adjust thanks to its stepless manual adjustment which requires no tooling.

Cuts close to walls or ground
Possible thanks the reversible cutting arm of the K770.

Easy and optimal belt tensioning
The incorporated SmartTension™ semi-automatic belt tensioning system ensures optimal power transmission, minimum wear and maximum belt life, eliminating the risk of under and over tensioning the poly V -belt.

Poly V-belt
Provides better transmission of power and requires less frequent re-tensioning and extended service intervals.

Virtually maintenance-free starter
The incorporated Durastarter™ is a dust-sealed starter where the return spring and the pulley bearing are sealed to provide a virtually maintenance-free starter, complimented by the specially developed durable starter cord.

Active Air Filtration™
Two-step filtration system with centrifugal cleaning and a single paper filter increase product life and extends service intervals.

Virtually maintenance-free air filter
The only time the filter needs to be checked and changed is if a lack of power is experienced.

Long service intervals
The use of a strong poly V-belt combined with Durastarter™ and the highly efficient Active Air Filtration™ filter system ensures long service intervals.

Less slurry and low water consumption
Excellent dust control thanks to the integral wet cutting kit supplied as standard, complete with a progressive water valve for exact adjustment of the water volume required to efficiently bind the dust and therefore reduce the volume of slurry generated.

Smooth blade stop
Reduces the stop time of the blade when the machine is switched off, enabling the user to quickly move on the next job.
