Husqvarna has released the next generation of 50cc chainsaws for professional loggers and arborists, the Husqvarna 550 XP Mark II and the 545 Mark II. The chainsaws are redesigned from scratch, resulting in a new level of cutting capacity, maneuverability and endurance, making them ideal for harvest forestry and urban forestry applications including felling, limbing, removals or cross cutting of small and mid-sized trees.

There are two new 50cc chainsaws with the new design features, the Husqvarna 550 XP Mark II and Husqvarna 545 Mark II.
Both have been developed to deliver outstanding cutting capacity for handling 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 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,” Gent Simmons, Husqvarna director of product management – forestry said.
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 with the previous generation of 50cc chainsaws from Husqvarna.
This was made possible by three key improvements:
- optimized airflow
- the addition of more cooling fins in critical areas that contribute to more effective cylinder heat dissipation
- 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 start-ability in hot conditions
- a completely new muffler keeps temperatures down.
The 50cc chainsaws also have a new air filter design, which 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 carburettor calibration.
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 moulded into the plastic for clear aiming and permanent guidance.
