CHARLOTTE, N.C., Sept. 8, 2026 /PRNewswire/ -- Husqvarna, a global leader in outdoor power products, introduces three new additions to its trusted 400-series chainsaw lineup: the 445S, 450S Rancher^®, and the all-new 450X Rancher^®. Built for residential users and landowners, the new models deliver improved performance, easier operation, and long-lasting durability across the platform.

A key addition is the Husqvarna 450X Rancher^®, the first 400-series chainsaw equipped with AutoTune™ technology.

With up to 30% faster cutting**, a durable hybrid crankcase, and an upgraded X-Torq^® engine, the 450X Rancher^® delivers professional-level performance within Husqvarna's residential lineup.

The new 445S and 450S Rancher^® build on the proven 400-series platform with upgrades that boost efficiency and durability. Both models feature optimized X-Torq^® engines and reinforced crankcase designs for improved cooling and performance. The 445S delivers up to 20% faster cutting*** compared to its predecessor, along with enhancements such as a quick-release cylinder cover, captured bar nuts, and high-visibility felling marks. The 450S Rancher^® continues the legacy of Husqvarna's best-selling Rancher series****, offering dependable performance for landowners managing larger properties and demanding workloads.

Across all three models, Husqvarna integrates proven technologies including Smart Start^® for easier ignition, Air Injection™ to extend engine life, and LowVib^® to reduce operator fatigue.
