50.1 cc X-Torq® Power
The 550 XP® Mark II uses a 50.1 cc X-Torq® two-stroke engine producing approximately 4 hp. This provides the power needed for professional cutting while keeping the saw relatively compact.
The X-Torq® engine is designed to improve combustion efficiency while helping reduce fuel consumption and exhaust emissions compared with conventional two-stroke engine designs.
20-Inch Guide Bar
The 20-inch guide bar provides the 550 XP® Mark II with its maximum recommended bar length. This configuration is particularly useful when additional reach and cutting capacity are required.
It is suitable for:
- Tree felling
- Bucking larger logs
- Limbing larger branches
- Firewood processing
- Forestry maintenance
- Land management
- Storm-damage cleanup
The .325-inch pitch and .050-inch gauge SP33G chain are designed to work with the saw's 50 cc professional power class.
AutoTune™ Technology
The integrated AutoTune™ system automatically adjusts the engine's fuel-air mixture to help maintain consistent performance as operating conditions change.
This can compensate for variables such as temperature, altitude, fuel quality, and air-filter condition, reducing the need for frequent manual carburetor adjustment.
Air Injection™ System
The Air Injection™ centrifugal air-cleaning system helps separate larger dust and debris particles before they reach the air filter.
This is especially beneficial in forestry environments where sawdust, bark, dirt, and other airborne debris can accumulate quickly.
LowVib® Vibration Reduction
The 550 XP® Mark II features LowVib® technology, which helps isolate engine and cutting-system vibration from the operator's hands.
Reduced vibration can make extended cutting more comfortable and help the operator maintain better control during repeated forestry tasks.
Optimized Cooling System
Heavy cutting can generate significant engine heat. The 550 XP® Mark II's optimized cooling system is designed to help manage engine temperatures during demanding operation.
This supports reliable performance when the chainsaw is used for extended periods in professional forestry and tree-care applications.
Durable Professional Construction
A forged three-piece crankshaft is designed to withstand the stresses associated with professional chainsaw operation.
The saw also incorporates a side-mounted chain tensioner for convenient adjustment and an adjustable oil pump that allows chain lubrication to be tailored to working conditions.
Chain Lubrication and Maintenance
The automatic chain-oiling system delivers lubricant to the guide bar and chain during operation. The adjustable oil pump gives the operator additional control over oil delivery.
Retained bar nuts help prevent the nuts from becoming separated from the saw during maintenance, while the side-mounted tensioner provides convenient access for chain adjustment.
Safety Features
The 550 XP® Mark II includes an inertia-activated chain brake designed to stop the chain when a sufficiently forceful kickback event occurs.
The machine should always be used with appropriate chainsaw PPE and according to the manufacturer's operating and safety instructions. Proper training and safe cutting technique remain essential.
Ideal Applications
The Husqvarna 550 XP® Mark II with a 20-inch bar is well suited for:
- Professional forestry
- Tree felling
- Limbing and bucking
- Arborist work
- Medium-sized tree removal
- Firewood processing
