Husqvarna K 770 Review

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 a semi-automatic SmartTension system allows for optimal power transmission, minimum wear and maximum belt life. The light weight, outstanding power-to-weight ratio, 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 the sidewalk when used with a KV7 trolley.


Easy and optimal belt tensioning

The semi-automatic SmartTension minimizes the risk of under/over tensioning.

Light and powerful

A light compact and powerful machine with a 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 Husqvarna’s maintenance-free starter DuraStarter and efficient filter-system Active Air Filtration ensures long service intervals.

Digital ignition with optimized timing

Provides a powerful spark with optimized timing, enabling easy start and efficient combustion.


Optimized engine performance

Optimized engine performance through efficient cylinder design, digital ignition system and X-Torq engine technology.

Fits multiple blade bushings

Blades with 20 mm and 25.4 mm bore can be fitted thanks to the reversible blade bushing.

Maintenance-free starter

The patented, dust-sealed starter unit seals the return spring and the pulley bearing. This makes the starter virtually maintenance free further boosting the reliability of our cutters.

Active Air Filtration

Husqvarna’s two-step filtration system with centrifugal cleaning and a single paper filter increases product life and extends service intervals.

Poly-V belt

Provides better transmission of power, less frequent re-tensioning and extended service intervals.

Blocks, curbstones and pavers

Cutting building blocks, curbstones and garden pavers.

Rescue cutting

Cutting in rescue operations.

Exceptionally low vibrations

Vibrations below 25m/s2 in the cutter handles for more comfort and longer operation periods.

Maintenance-free air filter

The only time the filter needs to be checked and changed is if you experience a lack of power.

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.


New DualCharge engine technology provides more power, lower fuel consumption and greatly reduced emissions.

Reduced wear

Reduced wear thanks to the drive belt with a fully sealed transmission, which keeps out the cutting dust.

Anti-vibration system

Husky’s anti-vibration system reduces vibrations in the cutter handles, so they’re more comfortable to hold and can be used for longer periods. The distance between the handles is large to enable the user a comfortable operating position and to reduce strain. The handles and the short engine body mean the user always stands close to the machine, for easier handling and control.


Husqvarna’s built-in automatic filter compensation maintains high power during the air filter lifetime.

Burying of cables

Burying of all kinds of cables.

Floors and walls

Regular cutting in floors and walls.

Blade shaft and bearings

Provide extended blade life and reduces maintenance.

Easy to start

The unique design of the carburetor, cylinder, and digital ignition system, together with air purge and decompression valve ensure an easy start.

High power with less fuel

Husky’s built-in automatic filter compensation SmartCarb maintains high power and lowers fuel consumption.

Easy to change blade guard position

The light magnesium blade guard facilitates cutting, thanks to its step-less adjustment.

Blade retarder

Reduces the stop time of the blade when the machine is switched off, which enables you to quickly move on to the next job.

Cuts close to walls or ground

The cutting arm is reversible which lets you cut closer to walls or the ground. The drive belt has a fully sealed transmission. This keeps out cutting dust, reducing wear on the belt.


Husqvarna’s virtually maintenance-free starter, thanks to the dust-sealed starter and the durable starter cord.
