Best in class cutting capacity.

The second generation of Husqvarna’s 550 XP® chainsaw is ready for demanding use in your felling, limbing and bucking operations. The saw delivers maximum power in the 50cc class. Designed for professional forestry and tree care crews, this durable saw has improved power and a slimmed-down design. A host of innovative features guarantee comfortable and efficient operation, season after season.

Features may include:

Excellent cooling capacity for a longer engine life
  • Our new cooling system is optimised in every detail to give you a reliable chainsaw for any situation.
Felling sight to last a lifetime
  • Having a perfect sight is critical when using a chainsaw – so we made one that’s permanently molded into the chainsaw for long-lasting felling accuracy.
Retained bar nuts
  • The retaining function prevents loosing the bar nuts.
LowVib® Technology
  • Dampeners between the engine and chassis significantly reduce vibrations so you can work more comfortably
Slimmed-down design
