Husqvarna Adds AutoTune Tech to New 450X Rancher Chainsaw
Charlotte, N.C. – September 11, 2026 -- Husqvarna has launched three new residential chainsaws -- the 445S, 450S Rancher, and 450X Rancher -- now available for homeowners and landowners.
The 450X Rancher becomes the first 400-series saw with AutoTune technology
AutoTune automatically adjusts engine settings based on fuel quality, altitude, temperature, and humidity. Combined with a simplified starting procedure, the 450X Rancher is up to 40% easier to start compared to the Husqvarna 450 Rancher, according to the company. It also cuts up to 30% faster than that predecessor model, thanks to a durable hybrid crankcase and an upgraded X-Torq engine.
