Husqvarna 550 XP Mark II Chainsaw Review

Introduction: Why the Husqvarna 550 XP Mark II Stands Out

As someone who has spent countless hours behind the handles of various chainsaws, tackling everything from dense hardwoods to delicate limbing, I can tell you that not all saws are created equal. When it comes to striking a balance between raw power, advanced technology, and user-friendliness, the Husqvarna 550 XP Mark II often comes to mind. It’s a saw that, in my professional opinion, truly elevates the experience for both the serious landowner and the demanding professional alike.

This isn’t just another chainsaw; it’s a tool engineered for those who demand consistent performance in challenging conditions. The “XP” in its name, which stands for “Extra Performance,” isn’t just marketing fluff. It signifies a saw designed for demanding professional use, but its accessible features also make it a fantastic choice for experienced homeowners and landowners tackling significant tree work. Before we dive deep into its mechanics, let’s understand why this model has earned such a revered spot in the chainsaw world.

What truly sets the 550 XP Mark II apart is its thoughtful combination of Husqvarna’s most innovative technologies with robust build quality. It’s a workhorse that doesn’t feel like a chore to use, offering a blend of power and precision that can make even the most daunting cutting tasks feel manageable. Whether you’re felling medium-sized trees, bucking logs for firewood, or clearing storm-damaged timber, this saw is designed to deliver, making every cut count.

Unpacking the Power: Features and Specifications

Engine and Performance

At the heart of the Husqvarna 550 XP Mark II lies a potent 50.1 cc X-Torq engine, delivering an impressive 3.0 kW (approximately 4.08 horsepower) of power. The X-Torq engine technology is a Husqvarna hallmark, designed to significantly reduce exhaust emissions and improve fuel efficiency compared to conventional two-stroke engines. This means you get more work done on a tank of fuel while being a bit kinder to the environment, a win-win in my book.

What truly sets this engine apart is Husqvarna’s AutoTune technology. Think of AutoTune as a sophisticated electronic carburetor that continuously optimizes the engine’s settings for maximum performance in varying conditions. Whether you’re working at high altitudes, in humid conditions, or with different fuel mixtures, AutoTune automatically adjusts, ensuring peak power and smooth operation without manual carburetor fiddling. This feature alone drastically simplifies operation and boosts reliability, especially for users who might not be comfortable making carburetor adjustments.

The saw typically accommodates guide bars ranging from 13 inches up to 20 inches, with a 15-inch or 18-inch bar being the most common and versatile choices for its power class. It usually runs on a .325-inch pitch chain with a .050-inch (1.3 mm) or .058-inch (1.5 mm) gauge, offering a good balance of cutting speed and durability. For most users, a semi-chisel chain is a great all-around choice for its balance of sharpness retention and ease of sharpening, while full-chisel will provide faster, more aggressive cuts for experienced operators.

Ergonomics and Durability

When you pick up the 550 XP Mark II, the first thing you notice is its excellent power-to-weight ratio. Weighing in at approximately 11.7 lbs (5.3 kg) without the bar and chain, it feels substantial yet surprisingly agile. This balance is crucial for reducing fatigue during long cutting sessions, allowing for more precise control and safer operation. The slimmed-down body and high center of gravity contribute to its excellent maneuverability, making it feel less cumbersome than some other saws in its class.

Husqvarna has also incorporated advanced LowVib anti-vibration dampeners, which significantly reduce the vibration transmitted to your hands and arms. This feature is a game-changer for anyone who spends more than a few minutes with a saw, as excessive vibration can lead to discomfort, fatigue, and even long-term health issues. The intuitive controls, including a combined choke/stop control, further enhance ease of use, minimizing the risk of engine flooding and simplifying startup procedures.

Durability is another area where the 550 XP Mark II shines. Its magnesium crankcase is built to withstand tough professional use, ensuring a long service life. The Air Injection system, a centrifugal air cleaning system, removes larger dust and debris particles before they reach the air filter, extending service intervals and maintaining consistent power. This robust construction means the saw is ready to tackle the rigors of frequent, demanding use, providing reliable performance year after year.

Real-World Performance and Handling

Cutting Power and Efficiency

In the field, the Husqvarna 550 XP Mark II truly comes alive. Its 4-horsepower engine provides ample torque for aggressive cutting, effortlessly powering through hardwoods like oak, maple, and hickory. I’ve personally used this saw to fell 12-18 inch diameter trees, and it handles them with remarkable ease. The rapid acceleration, a characteristic of XP saws, means the chain gets up to speed quickly, minimizing bog-down and improving cutting efficiency. This rapid response is particularly valuable when limbing, where quick, precise cuts are essential.

For bucking – cutting logs into shorter lengths – the saw maintains consistent power even under load. The AutoTune system plays a vital role here, ensuring the engine always runs at its optimal setting, regardless of the workload or external conditions. This translates into less downtime for adjustments and more time spent cutting. Whether you’re preparing firewood or clearing a large fallen tree, the 550 XP Mark II delivers a smooth, powerful cut that instills confidence.

The saw’s excellent balance also contributes significantly to its cutting prowess. When you’re making complex felling cuts or precise limbing, a well-balanced saw feels like an extension of your arm. The slim profile and well-placed handles allow for precise control, reducing the likelihood of fatigue-induced errors. It’s the kind of saw that makes you feel more capable, allowing you to focus on the cut itself rather than wrestling with an unwieldy machine.

Starting and Maintenance Made Easy

Starting the 550 XP Mark II is generally straightforward, thanks in part to the AutoTune and the Smart Start feature, which reduces resistance in the starter cord. A cold start typically involves pulling the choke out, priming a few times, and then a few firm pulls until it sputters. Push the choke in halfway (or to the idle position if it’s a combined control), and another pull or two usually gets it running smoothly. Warm starts are even simpler – just a firm pull or two, and you’re back in action.

Routine maintenance is crucial for any chainsaw, and the 550 XP Mark II is designed to make it as hassle-free as possible. The side-mounted chain tensioner allows for quick and easy chain adjustments. The flip-up fuel and oil caps are also a nice touch, making refueling and topping off bar oil less messy. Daily checks should include inspecting the chain for sharpness and damage, checking chain tension, cleaning the air filter (which is easily accessible), and ensuring the oiler is functioning correctly. Periodically, you’ll want to clean the spark plug, check the starter cord, and inspect the guide bar for wear.

For more in-depth maintenance, such as sharpening the chain, I recommend using a filing guide or, better yet, a dedicated chain sharpener to maintain the correct angles. For a .325″ pitch chain, a 3/16″ (4.8mm) round file is typically used. Keeping the chain sharp not only improves cutting efficiency but also significantly reduces kickback risk and engine strain. With regular care, the 550 XP Mark II will remain a reliable partner for many years.

Safety First: Operating Your 550 XP Mark II Responsibly

Essential Personal Protective Equipment (PPE)

Before you even think about starting your Husqvarna 550 XP Mark II, or any chainsaw for that matter, safety must be your absolute priority. This saw is powerful, and while it’s designed with user safety in mind, improper use can lead to serious injury. Always wear appropriate Personal Protective Equipment (PPE). This includes a hard hat with a face shield and hearing protection (a combo helmet is ideal), cut-resistant chainsaw chaps or trousers, sturdy work boots (preferably steel-toed and cut-resistant), and durable work gloves.

These aren’t optional accessories; they are non-negotiable safety barriers. I’ve seen firsthand how a moment of inattention or an unexpected kickback can be mitigated by wearing the right gear. For instance, chainsaw chaps are designed with layers of special fibers that can snag and stop a moving chain, potentially saving a limb. Never operate a chainsaw without this full complement of protective gear.

Safe Starting and Cutting Techniques

Starting the 550 XP Mark II safely requires a clear understanding of proper procedure. Always place the saw on firm, level ground, ensuring the chain brake is engaged. Brace the saw firmly with your foot on the rear handle and one hand gripping the front handle, then pull the starter cord with the other. Never drop-start a chainsaw; it’s incredibly dangerous and puts you at a high risk of losing control. Once it starts, let it warm up for a few moments, then disengage the chain brake.

When it comes to cutting, always plan your cuts and be aware of your surroundings. For felling trees, ensure your escape routes are clear and that there are no people or obstacles in the fall zone. Understand the lean of the tree and use proper felling techniques (notch and back cut). When limbing, work from the bottom up, cutting small limbs first and avoiding cutting between the log and a branch under tension, which can cause springback. For bucking, position logs stably and be mindful of pinch points, using wedges if necessary to prevent the bar from getting trapped.

Kickback is a serious concern with any chainsaw. It occurs when the tip of the guide bar contacts an object or gets pinched, causing the saw to suddenly and violently thrust back towards the operator. The 550 XP Mark II has a low kickback chain and a chain brake that activates quickly, but operator vigilance is paramount. Always maintain a firm grip with both hands, keep your thumbs wrapped around the handles, and avoid cutting with the tip of the bar. Being aware of the kickback zone and avoiding it is the best defense.
