Husqvarna unveils the company’s next generation of 50cc chainsaws for professional loggers.
Coming 60 years after the launch of its very first saw, Husqvarna this year introduces two new 50cc chainsaws with a ground-up new design and engineering. The new chainsaws, Husqvarna 550 XP® Mark II and Husqvarna 545 Mark II, have been developed to deliver good 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.
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; which are an optimized airflow, the addition of more cooling fins in critical areas that contribute to more effective cylinder heat dissipation, and 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 carburettor 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.
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. The 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.
