The new K760 is the latest generation of Husqvarna power cutters. Built on the foundation of the popular K750, the K760 is equipped with Husqvarna’s X-Torq engine that reduces emissions up to 75 per cent and lowers fuel consumption.

Specially developed for two-stroke engines, X-Torq utilizes dual intakes: one for clean air and one for a fuel-air mixture. The clean air intake forms a barrier that delays the fresh fuel mix from entering the engine while assisting in exhausting the burnt gases. Then the fuel-air mixture flushes into the engine, resulting in more power and fewer emissions, compared to conventional two stroke engines.

Another important innovation is the enhanced Active Air Filtration system. It contains a new centrifugal nozzle that increases the level of filtration and a new paper filter with a doubled surface. The new system extends filter-life and therefore allows the saw to run for up to one year without filter service, saving time and money.  

The K760 features an impressive power-to-weight ratio and low vibrations that reduce operator fatigue and enable longer cutting time.

The K760 is part of a new family of power cutters that will be introduced throughout 2010. Additional power cutters include the K760 Cut-n-Break and K760 Rescue.
