The Husqvarna 455 Rancher is a redesign of their sturdy, powerful all around Rancher line for landowners and part-time users. The new X-TORQ engine provides high torque over a very wide rpm range. The low exhaust emission levels, in accordance with EPA 2, are achieved without a catalytic converter. Durable saw body with a three-piece crankshaft and reinforced crankcase ensure your saw will get the job done for a long time to come. The Smart Start and compression release starter provide easy starting every time. The LowVib and a dual action chain brake ensure your comfort and safety. This chainsaw utilizes Husqvarna's Air Injection system to make the saw run stronger and longer.
