Professional 50cc performance without unnecessary weight
The Husqvarna 550 XP Mark II occupies an important position in Husqvarna’s professional chainsaw range. It delivers considerably more cutting performance and durability than a typical homeowner chainsaw, while remaining lighter and more manoeuvrable than a larger 60cc or 70cc forestry saw.
This makes it an excellent choice for professional forestry workers, tree surgeons, contractors, estate teams and experienced landowners who require a fast, dependable saw for repeated cutting. It is particularly well suited to felling, limbing and bucking small to medium-sized trees.
The narrow body and responsive engine make the 550 XP Mark II especially effective when completing repeated limbing cuts or working in areas where accurate handling matters as much as outright engine size.
For occasional garden maintenance and lighter firewood work, the smaller Husqvarna 435 II petrol chainsaw may be more suitable. For heavier forestry work and regularly cutting larger timber, consider the more powerful Husqvarna 560 XP professional chainsaw.
Why choose the Husqvarna 550 XP Mark II?
Powerful 3kW X-Torq® engine
The 50.1cc X-Torq engine produces 3kW and drives the chain at up to 19.6m/s at maximum power. This provides the strong cutting response and rapid acceleration required for efficient professional felling, limbing and timber processing.
X-Torq technology is designed to provide strong torque and cutting performance while supporting efficient fuel use and controlled exhaust emissions.
AutoTune™ automatic engine adjustment
Husqvarna AutoTune automatically adjusts the engine settings to suit changing operating conditions. It compensates for factors including temperature, altitude, fuel quality and air-filter condition, helping the chainsaw maintain consistent performance without routine manual carburettor adjustment.
This is particularly useful for professional operators who work throughout the year or move between different sites and conditions.
Fast acceleration and high cutting capacity
The 550 XP Mark II has been developed to respond quickly when the throttle is applied. Fast acceleration helps the chain reach an effective cutting speed rapidly, which is valuable during repetitive limbing and when completing multiple cuts in quick succession.
Slim and manoeuvrable design
At 5.3kg excluding the bar and chain, the 550 XP Mark II offers an excellent power-to-weight ratio. Its slimmed-down body and balanced construction make it easier to reposition between cuts than a larger professional forestry saw.
This combination of power and agility is one of the principal reasons the 550 XP Mark II is so well suited to professional limbing and small-to-medium tree work.
LowVib® anti-vibration system
Husqvarna’s LowVib system uses dampening elements to reduce the level of engine vibration transferred to the handles. This improves comfort and helps reduce fatigue during longer working sessions.
The published equivalent vibration levels are 4.0m/s² at the front handle and 4.6m/s² at the rear handle.
Optimised cooling
The Mark II design incorporates an optimised cooling system that helps regulate engine temperature during demanding work. Effective cooling supports engine durability and dependable operation when the chainsaw is being used regularly.
Air Injection™ filtration
Husqvarna’s centrifugal Air Injection system removes larger dust and debris particles before they reach the main air filter. This helps keep the filter cleaner for longer and supports reliable engine performance in dusty working environments.
Professional construction
The 550 XP Mark II is engineered for demanding professional use. Features such as its magnesium crankcase, three-piece crankshaft, retained bar nuts, side-mounted chain tensioner and adjustable oil pump support durability, servicing and efficient day-to-day operation.
Should I choose the 15-inch or 18-inch version?
Husqvarna 550 XP Mark II 15-inch – 967690815
The 15-inch version is the best choice when manoeuvrability, balance and rapid handling are the main priorities. The shorter guide bar keeps the overall machine compact and is particularly effective for:
- Professional limbing
- Felling small and medium-sized trees
- Processing manageable timber
- Working in denser woodland
- Jobs involving frequent repositioning of the chainsaw
Manufacturer product number: 967690815
Guide-bar length: 15 inches / 38cm
Supplied chain: Husqvarna S35G, .325-inch pitch, 1.5mm gauge
Husqvarna 550 XP Mark II 18-inch – 967690818
The 18-inch version provides additional reach and cutting capacity while using the same professional 50.1cc powerhead. It is a better choice for operators who regularly encounter larger-diameter timber but still want the agility of a 50cc saw.
- Felling and processing medium-sized trees
- Cutting larger logs and timber
- Estate and woodland management
- Professional work requiring a little more reach
- Operators wanting greater capacity without moving to a 60cc saw
Manufacturer product number: 967690818
Guide-bar length: 18 inches / 45cm
Supplied chain: Husqvarna S35G, .325-inch pitch, 1.5mm gauge
Husqvarna specifies a recommended guide-bar range of 13 to 20 inches for the 550 XP Mark II. Always use a compatible guide bar and chain with the correct pitch, gauge and drive-link count.
