The new Husqvarna K770 power cutter offers some upgrades to the K760 we just reviewed. You can see things like slightly more weight but less vibration.
- Vibration lower than K760
- Intelligent tensioning system keeps the belt tensioned and keeps the sawing smooth
- Upgraded crankcase is stronger
- Cooling fan reduces transmission temperature and increases service life
- Lightweight for 14" power cutters
- More powerful engine than similarly priced models from Hilti, Stihl and Makita
- no major disadvantages
The Husqvarna K770 is a good 14" power cutter that I can recommend for cutting any masonry up to 5".
The digital ignition remains and has been updated to deliver a powerful spark and optimized timing for easy starting and efficient combustion.
I have no problem booting the K760 – it will still boot on the first or second pull. I expect this upgrade to be consistent for a longer period of time in the future.
Intelligent Tensioning System
The Husqvarna K770 has a spring loaded system that makes it easy to ensure that the drive belt is always at the correct tension. This gives you optimal power transmission and reduces wear while extending the life of the belt.
The cutting arm has a cast magnesium crankcase with a three-bolt joint for attaching the cutting head. This helps make it more torsional rigid than previous two-bolt casings. It substantially reduces the amount of flex you've felt from previous saws.
A clutch cooling fan reduces operating temperatures inside the belt cover. Transmission components have longer maintenance intervals and a longer service life.
- Maintenance-free air filter
- Reduced pulp
- improve fuel efficiency
- lower emissions
- Maintenance-free DuraStarter
- active air filtration
- Smart Carbs
As a mason, I use a power cutter for a variety of cutting projects – concrete blocks, bricks, rebar, foundations, landscape rock, and more. A 14-inch knife like this one is a great all-rounder, and you can cut down to 5 inches deep.
At first glance, there isn't much difference between the Husqvarna K770 and K760, especially since they share the same 4.48 cubic inch engine. But some of these improvements have real benefits when you're working with a saw.
The whole saw feels very solid during the cut. This is partly due to the increased strength of the crankcase. Not only that, but Husqvarna has further reduced the vibrations of the K760.
When the belt on other saws starts to loosen, you'll start to feel more vibration, and if it's really bad, the belt will slip slightly. The SmartTension system is known for making cuts extremely smooth and keeping them that way over time.
The K770 is a bit heavier than the K760, at 22.4 pounds dry, an increase of less than a pound. However, it is still easy to handle and has excellent performance in this class.
The Husqvarna K770 power cutter has a list price of $1225, but as of mid-January 2019 retails for nearly $920.
- Makita EK7301: $869
- Hilti DSH 700-X": $899
- Husqvarna K770: $918
- Makita EK7651H (four-stroke): $1199
- STIHL TS 500i: $1399.95
The K760 isn't cheap, but it doesn't seem like much compared to what you're getting from this powerhouse. It's on the same level as the 2-stroke models from Makita and Hilti, and gives you a little more engine power than either. There's a comfortable gap before you get into the Makita's 4-stroke, and the Stihl's is a completely different price tag.
the bottom line
The K760 is one of the best 14" power cutters I have ever used. The Husqvarna K770 power cutter improves overall quality and design, but it's still under $1000.
