Husqvarna 450X Rancher

The Husqvarna 450X Rancher® is redefining ease for gas chainsaws. Whether the engine is cold or warm, the simple starting procedure delivers 40% easier starting*. While the pro-grade power of AutoTune™ automatically adjusts the engine settings to ensure maximum performance. The patented crankcase design has been optimized for engine cooling, helping deliver reliable and long-lasting performance. Our patented X-TORQ® engine maximizes power, even at low RPMs, to deliver an all-around powerhouse you can count on season after season.

The 450X Rancher is the first 400-series chainsaw with AutoTune™ technology, which automatically adjusts engine settings for optimal performance in any environment.

The 450X Rancher is 40% easier to start than the previous 450 Rancher, thanks to its super simple starting interface and AutoTune™.

It comes with a 20" bar (recommended range: 13"–20") and uses the SP33G X-Cut chain.

The 450X Rancher includes a reinforced crankcase, quick-release air filter, captured bar nuts, automatic oil pump, and colored felling marks.

Like the other models, it features LowVib®, inertia-activated chain brake, side-mounted chain tensioning, and a flip-up fuel cap.

The 450X Rancher is covered by a 2-year limited warranty for residential use, with the option to extend up to 5 years if you purchase qualifying Husqvarna pre-mixed fuel & oil and register your product online.
