Practical, robust 55cc chainsaw for demanding cutting jobs. The 455 Rancher pairs a high-torque X-Torq® engine with LowVib® dampening and service-forward features such as a side-mounted chain tensioner and quick-release air filter. Weight is 6 kg (excl. cutting equipment); the saw is supplied with a 45 cm (18 in) bar and set up for immediate use.
Strong, efficient power
The 55.5 cm³ X-Torq® engine delivers high torque and efficient combustion for heavy cutting tasks while improving fuel use compared with older designs.
Easier starting
SmartStart® construction, combined choke/stop control and an air purge make starts quicker and reduce starter cord resistance by up to 40%, so the saw starts reliably with less effort.
Reduced wear and longer filter life
Air Injection™ centrifugal cleaning removes larger dust particles before they reach the filter, extending time between cleanings and reducing engine wear.

FAQs
How many CC is a Husqvarna 455 Rancher?
The Husqvarna 455 Rancher has an engine displacement of 55 cubic centimeters (CC).
How much does a Husqvarna 455 Rancher weigh?
6 kg excl. cutting equipment
Is a Husqvarna 455 Rancher a Pro saw?
No, the Husqvarna 455 Rancher is not classified as a professional chainsaw. It belongs to Husqvarna’s 400-series, which offers higher performance, improved ergonomics, and more advanced features compared to chainsaws in the 100–300 series. The 400-series is designed for users who need reliable power and durability for regular and demanding tasks, without the specifications of a fully professional saw.
How easy is the 455 Rancher to start?
Designed for easier starting: SmartStart® design reduces starter cord resistance, the air purge removes air from the carburettor and combined choke/stop control simplifies choke management. Expect fewer pulls to start compared with older two-stroke saw designs; follow the starting procedure in the manual for best results.
What routine maintenance should I plan for?
Check chain tension and lubrication before each use, keep the air filter and cooling fins clean, and inspect the sprocket nose and chain wear regularly. The side-mounted chain tensioner, quick-release air filter and adjustable oil pump make these checks quicker; always use parts and consumables specified by Husqvarna.
What are the vibration and noise levels, and what PPE do I need?
Equivalent vibration levels are 6.9 m/s² (rear handle) and 3.8 m/s² (front handle). Sound pressure at the operator’s ear is 107 dB(A) with a guaranteed sound power level of 115 dB(A). Use appropriate hearing protection, eye protection and protective clothing (helmet, gloves, chainsaw trousers/boots) and follow local safety regulations.
