The cutting system's power, in turn, is provided by a 55.5 cc two-stroke gasoline engine with X-Torq technology, making this chainsaw the most powerful model in Husqvarna's residential range. The X-Torq system works by ensuring that fuel is burned more completely, thus increasing performance, reducing emissions by up to 75% and increasing fuel efficiency by 20%. This gives the Husqvarna 455 RANCHER a significant advantage over similar chainsaws equipped with a conventional two-stroke engine, along with the added benefit of being better for the environment. Another intelligent feature developed by Husqvarna is the new and improved version of its always reliable Smart Start system, which reduces starter cable resistance by 40%, saving time and effort during starting.

Supplied with a 45 cm (18″) bar and 0.325″ pitch chain, the Husqvarna 455 RANCHER is a versatile and easily customizable machine with a bar and chain combination that adapts to the task at hand. Furthermore, with a maximum chain speed of 20 m/s, this impressive machine will handle even the toughest residential cutting job with enviable ease. For added kickback protection, an effective inertia-activated chain brake is also included.
