2024 Husqvarna K770

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 maximised productivity. Suitable for road work and easy to cut in a straight or curved track or close to sidewalk when used with KV7 trolley.

Features* Easy and optimal belt tensioning: The semi-automatic SmartTension minimises 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.
* Digital ignition with optimised timing: Provides a powerful spark with optimized timing, enabling easy start and efficient combustion.
* Exceptionally low vibrations: Vibrations below 2.5 m/s2 in the cutter handles for more comfort and longer operation periods.
* 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.
* Maintenance-free air filter: The only time the filter needs to be checked and changed is if you experience lack of power.
* High power with less fuel: Our built-in automatic filter compensation SmartCarb™ maintains high power and lowers fuel consumption.
* Optimised 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.
* Fits multiple blade bushings: Blades with 20mm and 25.4mm bore can be fitted thanks to the reversible blade bushing.
* Efficient power performance: Our X-Torq® engines deliver great power and torque thanks to highly efficient combustion.
* Smooth blade stop: Reduces the stop time of the blade when the machine is switched off, which enables you to quickly move on to the next job.
* Maintenance-free starter: Our dust-sealed starter, where the return spring and the pulley bearing are sealed, gives a virtually maintenance free starter. Developed with a durable starter cord.
* Reduced wear: Reduced wear thanks to the drive belt with fully sealed transmission, which keeps out the cutting dust.
* Cuts close to walls or ground: Possible thanks to the reversible cutting arm
* Active Air Filtration™: Our two-step filtration system with centrifugal cleaning and a single paper filter increases product life and extends service intervals.
* Anti-vibration system: Reduced vibrations in the cutter handle for more comfort and longer operation periods.
* DuraStarter™: Our virtually maintenance free starter, thanks to the dust-sealed starter and the durable starter cord.
* Poly-V belt: Provides better transmission of power, less frequent re-tensioning and extended service intervals.
* SmartCarb™: Our built-in automatic filter compensation maintains high power during the air filter life time.
* Asphalt: Asphalt cutting in roadworks.
* Blocks, curbstones and pavers: Cutting building blocks, curbstones and garden pavers.
* Burying of cables: Burying of all kinds of cables.
* Cast concrete: Cutting cast concrete.
* Floors and walls: Regular cutting in floors and walls.
* Rails: Rail cutting.
* Rescue cutting: Cutting in rescue operations.
* Blade shaft and bearings: Provide extended blade life and reduces maintenance.
