Husqvarna 455 Rancher

2-Stroke

The Husqvarna 455 Rancher is a 55.5cc 2-stroke chainsaw and the flagship of Husqvarna's consumer Rancher line, targeting farmers, ranchers, and rural property owners who need production-capable cutting with 18" to 24" guide bars. The Rancher branding signals heavier construction and higher-volume use than the E-series. The 455 runs a Zama or Walbro carburetor <!-- verify: husqvarna.com/us --> with the X-Torq engine and Air Injection filtration. Common maintenance items under Rancher use are the spark plug, air filter, fuel filter, primer bulb, and bar oiler.
