The Husqvarna K770 power cutter is an upgraded version of the K760 that we recently reviewed. While it maintains a similar design and engine size, it boasts several improvements that enhance its performance. These upgrades include reduced vibration and increased durability, among others.
- Vibration reduction compared to the K760
- Intelligent tensioning system ensures optimal power transmission and smooth sawing
- Stronger crankcase for enhanced durability
- Cooling fan regulates transmission temperature, prolonging service life
- Lightweight for a 14″ power cutter
- More powerful engine than similarly priced models from Hilti, Stihl, and Makita
- No major disadvantages found
I highly recommend the Husqvarna K770 as a reliable 14″ power cutter suitable for cutting masonry up to 5″ in thickness.
The K770 features an updated digital ignition system that delivers a powerful spark and optimized timing for effortless starting and efficient combustion.
I personally have no issues starting the K760, usually getting it running on the first or second pull. With the K770, I expect even more consistent performance and reliability in the long run.
Intelligent Tensioning System
The K770 is equipped with a spring-loaded system that simplifies belt tension adjustment. This ensures optimal power transmission, reduces wear, and extends the life of the belt.
The cutting arm of the K770 features a cast magnesium crankcase with a three-bolt joint for attaching the cutting head. This design significantly improves torsional rigidity compared to previous models with two-bolt casings, minimizing flex during operation.
The inclusion of a clutch cooling fan in the K770 helps maintain lower operating temperatures within the belt cover. This results in longer maintenance intervals and an extended service life for the transmission components.
- Maintenance-free air filter
- Reduced pulping
- Improved fuel efficiency
- Lower emissions
- Maintenance-free DuraStarter
- Active air filtration
- Smart Carbs
As a mason, I frequently rely on power cutters for various cutting projects involving concrete blocks, bricks, rebar, foundations, and landscape rock, among others. With its 14-inch blade, the K770 proves to be an excellent all-round performer, allowing cuts of up to 5 inches in depth.
At first glance, the differences between the Husqvarna K770 and K760 may not be apparent, as they share the same engine displacement of 4.48 cubic inches. However, the improvements implemented in the K770 provide tangible benefits during actual sawing tasks.
The overall solidity of the K770 during operation can be attributed to its reinforced crankcase. Additionally, Husqvarna has significantly reduced vibrations in the K770, further enhancing user comfort.
While other saws may experience increased vibration when the belt loosens, resulting in potential performance issues, the K770’s SmartTension system ensures remarkably smooth cuts that remain consistent over time.
The K770 weighs slightly more than the K760, with a dry weight of 22.4 pounds, an increase of less than a pound. Nevertheless, it remains easy to handle and delivers outstanding performance within its class.
The Husqvarna K770 power cutter carries a list price of $1,225. However, as of mid-January 2019, it is available at retail prices nearing $920.
- Makita EK7301: $869
- Hilti DSH 700-X: $899
- Husqvarna K770: $918
- Makita EK7651H (four-stroke): $1,199
- STIHL TS 500i: $1,399.95
Compared to other models in its price range, the K760 offers exceptional value for money. It competes directly with the 2-stroke models from Makita and Hilti, providing superior engine power. Furthermore, there is a noticeable price jump before reaching the Makita’s 4-stroke option and even more significant price disparity with the Stihl model.
The Bottom Line
The K760 already stood out as one of the best 14″ power cutters available, but the Husqvarna K770 power cutter takes overall quality and design improvements to the next level. It continues to provide exceptional performance while remaining affordably priced, making it an excellent choice for any professional.
