Husqvarna have finally introduced to the market their new K770 petrol saw. This new model has been brought in to replace the popular, old faithful, the K760 saw. So what’s the difference you are all asking?
The K760 saw has been a market leader for over 10 years now and has attracted a huge, loyal fanbase due to is reliability and performance. Whatever was thrown at it on site the saw never failed to deliver, cutting bricks, blocks and slabs with ease helped by its superb power to weight ratio.
The good news then from Husqvarna is that as great as the K760 saw was the new K770 has several incremental improvements. They claim they have made a great saw even greater!
The main element which the designers focused on for the new machine was the digital ignition. The Husqvarna DuraStarter™ technology was present in the K760, but the optimised timing of the ignition spark has now further improved on the K770 model.
The cutting arm of the K770 is even more rigid and robust than its predecessor, thanks to the reconfigured three-bolt joint that attaches to the cutting head. This provides a really heavy duty feel and reduces the need for replacement parts.
Longevity and performance of the drive belt can be a key factor in the frequency of service and repair call outs, so Husqvarna have introduced SmartTension on the latest model. They claim this will greatly reduce downtime and in turn improve ROI on hire machines.
The above changes combine to improve the stability of the K770 whilst still limiting the vibration levels to a maximum of 3m/s² and the weight to 10kg. The new saw still delivers a power to weight ratio of 0.37.

The Model Options
The most popular variant of the Husqvarna K760 and K770 disc cutters have always been the standard petrol versions. These are available in the 12" and 14” blade size versions.
Husqvarna also introduced the Oilguard versions to the market, these include the K760 Oilguard and K770 Oilguard. This technology was developed to reduce the risk of misfuelling, as applicable models are designed to recognise the pigment in Husqvarna Oilguard two stroke oil and will place the machine into limp mode if an insufficient oil/fuel mix is present.
The K760 Cut-n-Break uses a pair of special blades and a unique breaking tool to cut channels with up to 400mm depth when cutting in stages. The K770 Cut-n-Break version is yet to be launched on the market but expect improvements that are similar to those between the standard K760 and standard K770 machines.
