Husqvarna 450S Rancher

Husqvarna 450S is a landowner chainsaw designed to tackle everything from forestry tasks like felling, cutting, and limbing to cutting firewood. Based on the reliable 400 series, this light chainsaw boasts a reinforced, robust design to increase product lifetime. It is equipped with a powerful and optimized 2.4 kW X-Torq® engine for increased performance. The refined starting procedure is further improved by the Smart Start® feature. Additional features, such as colored felling marks and captured bar nut, enhance the overall experience.

The 450S Rancher shares the same powerhead design as the 445S but delivers more horsepower (3.2 HP) and is part of Husqvarna’s best-selling Rancher series.

The 450S offers improved cutting capacity and efficiency, making it ideal for landowners tackling tough, demanding jobs.

The 450S has a 50.2 cc engine and comes with a 20" bar (recommended range: 13"–20").

The 450S uses the SP33G X-Cut chain.

Features include Smart Start®, quick-release air filter, captured bar nuts, visible felling marks, and a flip-up fuel cap.

The 450S includes LowVib®, inertia-activated chain brake, and side-mounted chain tensioning.

The 450S Rancher comes with a 2-year limited warranty for residential use. You can extend your warranty up to 5 years by purchasing at least 96 fl. oz. of Husqvarna pre-mixed fuel & oil at the same time as your chainsaw and registering your product online.

The warranty does not cover normal wear parts (such as air filters, spark plugs, chains, etc.), damage from improper maintenance, misuse, use of non-approved fuels (E15/E85), or commercial/rental use.

Using the chainsaw for commercial, agricultural, or rental purposes, failing to perform required maintenance, or using non-approved fuels will void the warranty.

Take your product and proof of purchase to an authorized Husqvarna servicing dealer. You are responsible for transportation costs. Registration is recommended but not required for service.

Keep your proof of purchase (receipt) for the entire warranty period, as Husqvarna may require it for verification before performing warranty work.
