Husqvarna unveils a new generation of 50cc chainsaws

Husqvarna unveiled the company’s next generation of 50cc chainsaws for professional loggers and arborists. The Husqvarna 550 XP® Mark II and the 545 Mark II have been redesigned from scratch. The results, according to Husqvarna, are a new level of cutting capacity, maneuverability and endurance, making them optimized for harvest forestry and urban forestry applications including felling, limbing, removals or cross-cutting of small and mid-sized trees.

“It’s not just a new chainsaw, it’s a new generation of chainsaws in which all vital parts are new.  The Husqvarna 550 XP® Mark II has a superior cutting capacity and has been proven through the most extreme testing to assure it meets expectations of our most demanding forestry and tree care professionals.  We are redefining the 50cc segment by setting a new standard for performance, durability, and maneuverability”, explained Gent Simmons, Director of product management, Forestry.

Improvements for endurance

For the purpose of endurance in tough conditions, the cooling capacity of the Husqvarna 550 XP® Mark II and Husqvarna 545 Mark II has been improved by 13 %, compared to the previous generation of 50cc chainsaws from Husqvarna. This is made possible by three key improvements: 1) an optimized airflow, 2) the addition of more cooling fins in critical areas that contribute to more effective cylinder heat dissipation, 3) an insulating heat shield, specifically developed for the new chainsaws, which provide sealing against the cylinder area and minimizes heat leakage. This helps keep the carburetor compartment cool to improve startability in hot conditions. In addition, a completely new muffler keeps temperatures down.

For further endurance, the 50cc chainsaws have a new air filter design. The new design comes from the combination of a redesigned air filter with higher capacity and improved sealing and an upgrade of the Air Injection™. This, in turn means the saws are equipped with a new optimized version of AutoTune™, Husqvarna’s ignition module software and carburetor calibration.

 
Designed for comfort and maneuverability

True to Husqvarna chainsaw heritage, the new generation of 50cc saws have a user-centric design. The well-balanced saw body with low gyroscopic forces provides excellent maneuverability and handling, enabling users to work longer without tiring. The ergonomically designed handles provide a safe, comfortable grip. In addition, the Husqvarna 550 XP® G Mark II and the Husqvarna 545G Mark II are equipped with heated handles, for more comfort during cold weather use.

Designed with the expert user in mind, the new 50cc chainsaws have two felling sights, one vertical and one horizontal – both are molded into the plastic for clear aiming and permanent guidance.

The chainsaws are manufactured in Huskvarna, Sweden.
