Powerful 50.1 cc X-Torq® Engine
The 550 XP® Mark II is equipped with a 50.1 cc X-Torq® two-stroke engine producing approximately 4 hp. The engine is designed to provide strong torque and rapid cutting performance while keeping the chainsaw compact enough for demanding forestry work.
X-Torq® technology is designed to improve combustion efficiency while helping reduce fuel consumption and exhaust emissions compared with conventional two-stroke engine designs.
Maneuverable 16-Inch Bar
The 16-inch guide bar gives this configuration an emphasis on maneuverability and control. The shorter bar is especially useful when working around branches, in dense tree canopies, or in locations where a longer bar could feel cumbersome.
The 16-inch configuration works well for:
- Limbing
- Small- and medium-sized tree felling
- Bucking
- Firewood cutting
- Arborist work
- Property maintenance
- General forestry tasks
The .325-inch pitch and .050-inch gauge SP33G chain provide a cutting system appropriately matched to the saw's power class.
AutoTune™ Engine Management
The integrated AutoTune™ system automatically adjusts the engine's fuel-air mixture to help maintain consistent operation as environmental and operating conditions change.
Temperature, altitude, fuel quality, and air-filter condition can all influence two-stroke engine performance. AutoTune™ helps compensate for these changes without requiring frequent manual carburetor adjustments.
Air Injection™ Filtration
Forestry work produces significant amounts of sawdust, bark, dirt, and airborne debris. The 550 XP® Mark II uses Air Injection™ centrifugal air-cleaning technology to help remove larger particles before they reach the air filter.
This helps reduce filter contamination and supports consistent engine performance during extended cutting work.
LowVib® Technology
The LowVib® system is designed to isolate vibration from the engine and cutting system before it reaches the handles.
For professional operators who use a chainsaw throughout the day, reduced vibration can improve comfort and make it easier to maintain control during repeated cutting operations.
Optimized Cooling for Heavy-Duty Use
The 550 XP® Mark II incorporates an optimized cooling system designed to help regulate engine temperatures during demanding operation.
This is particularly important when the saw is working continuously through larger timber or during extended forestry and land-management tasks.
Professional Construction
The chainsaw features a forged three-piece crankshaft engineered to withstand the stresses associated with professional use. Its overall construction is designed for frequent operation in demanding forestry environments.
A side-mounted chain tensioner makes chain adjustment more convenient, while retained bar nuts help prevent the nuts from becoming separated from the saw during servicing.
Adjustable Chain Oil Flow
The adjustable oil pump allows chain lubrication to be tailored to operating conditions. This provides the operator with greater control over oil delivery according to factors such as bar length, cutting conditions, and wood type.
Proper chain lubrication helps reduce friction and heat while supporting the service life of the bar and chain.
Safety and Operator Control
The 550 XP® Mark II includes an inertia-activated chain brake designed to stop the chain during a sufficiently forceful kickback event.
Operators should always use appropriate chainsaw protective equipment, inspect the machine before operation, maintain correct chain tension, and follow the manufacturer's safety and operating instructions.
Ideal Applications
The Husqvarna 550 XP® Mark II 16-inch chainsaw is well suited for:
- Professional forestry
- Tree felling
- Limbing
- Bucking
- Arborist work
- Small- and medium-sized tree removal
- Firewood processing
- Farm and ranch maintenance
- Land management
- Storm-damage cleanup
- Professional property maintenance
