Husqvarna unveiled the company’s next generation of 50cc chain saws for professional loggers and arborists, the Husqvarna 550 XP Mark II and the 545 Mark II. The chain saws are redesigned from scratch, resulting in 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.
Coming 60 years after the launch of its very first saw, Husqvarna this year introduces two new 50cc chain saws with a ground-up new design and engineering. The new chain saws, Husqvarna 550 XP Mark II and Husqvarna 545 Mark II, have been developed to deliver outstanding cutting capacity for handling small and mid-sized trees. Cutting capacity is the true measure of the performance of the saw. It is the speed at which the entire system of the bar, chain and powerhead works together to cut wood at optimal RPM. Through a series of internal tests*, Husqvarna has shown that the 550 XP Mark II provides best-in-class cutting capacity when comparing to the closest competitor in the 50cc segment.
“It’s not just a new chain saw, it’s a new generation of chain saws in which all vital parts are new. The Husqvarna 550 XP Mark II has 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 at Husqvarna.
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 chain saws 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 chain saws, 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 chain saws 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 chain saw 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 is equipped with heated handles, for more comfort during cold weather use.
Designed with the expert user in mind, the new 50cc chain saws have two felling sights, one vertical and one horizontal – both are molded into the plastic for clear aiming and permanent guidance.
The chain saws are manufactured in Huskvarna, Sweden, and equipped with a Husqvarna X-CUT chain and the X-force bar. Both 50cc chain saws will be available in stores from March 11, 2019. The MSRP will start at $539.95 for the 545 Mark II and $599.95 for the 550 XP Mark II.
