The Husqvarna K 770 12" is a powerful all-around 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 lightweight, outstanding power-to-weight ratio, 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 the sidewalk when used with a 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.
- Less emissions and fuel consumption
Our X-Torq® engine produces less emissions, lower fuel consumption and produces more power.
- 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.
