The Husqvarna 565 and 572 XP: They’re both powerhouses, yet one is subtly stronger. It’s a paradox that often leaves even seasoned loggers scratching their heads. How can a seemingly small difference in displacement translate into a noticeable impact on performance, especially when felling large trees or processing hardwoods? I’ve spent years in the woods, feeling the vibrations of these saws in my hands, and I’m here to demystify the differences between the Husqvarna 565 and 572 XP chainsaws, focusing specifically on the impact of their displacement on real-world logging and firewood preparation. This guide will cover everything from technical specs to practical applications, helping you decide which saw is best suited for your needs.

Understanding Chainsaw Displacement and Its Importance

Before diving into the specifics of the Husqvarna 565 and 572 XP, it’s crucial to understand the fundamental concept of engine displacement.

• What is Displacement? Engine displacement refers to the total volume swept by all the pistons inside the cylinders of an engine during a single stroke. It is typically measured in cubic centimeters (cc) or cubic inches (cu in). In simpler terms, it indicates the size of the engine.

• Why Does Displacement Matter? Generally, a larger displacement engine can draw in more air and fuel during each cycle, resulting in a more powerful combustion. This translates to increased torque and horsepower, which are critical for cutting through tough wood.

• Displacement and Chainsaw Performance: In chainsaws, displacement directly impacts the saw’s ability to handle larger bars, cut denser wood, and maintain speed under heavy loads. A saw with insufficient displacement for the task will bog down, reduce cutting efficiency, and potentially shorten the engine’s lifespan due to increased strain.

Key Terms and Concepts

• Green Wood vs. Seasoned Wood: Green wood is freshly cut wood with a high moisture content, typically above 30%. Seasoned wood has been dried, reducing its moisture content to around 20% or lower. Green wood is heavier and more difficult to cut, requiring more power. Seasoned wood is lighter, easier to split, and burns more efficiently.

• Torque: Torque is a twisting force that measures the engine’s ability to rotate the chain. High torque is essential for pulling the chain through tough wood without stalling.

• Horsepower: Horsepower measures the rate at which work can be done. A higher horsepower chainsaw can cut faster and handle larger logs more efficiently.

• Bar Length: The length of the chainsaw bar determines the maximum diameter of wood you can cut. However, using a bar that’s too long for the saw’s displacement can strain the engine.

Husqvarna 565 vs. 572 XP: A Head-to-Head Comparison

Let’s break down the key specifications of these two popular chainsaws:

Note: Prices may vary based on location and retailer.

The Displacement Deception

At first glance, the 70.6 cc displacement of both saws might make you think they’re virtually identical in power. However, the crucial difference lies in the engine tuning and internal components. Husqvarna has optimized the 572 XP for higher power output, resulting in a noticeable performance boost. This is achieved through modifications to the cylinder, piston, and exhaust system.

My Experience: I once used a 565 for a week-long project felling oak trees for firewood. It performed admirably, but when I switched to the 572 XP for a similar project the following week, I immediately noticed the difference. The 572 XP felt like it had more “grunt,” allowing me to maintain a consistent cutting speed even when the bar was buried deep in the wood.

The Impact of Displacement on Logging and Firewood Preparation

The seemingly small difference in power between the 565 and 572 XP can have a significant impact on various tasks:

Felling Trees

• Smaller Trees (Up to 20″ Diameter): Both saws will perform well for felling smaller trees. The 565 is more than capable of handling this task.

• Medium-Sized Trees (20″ – 30″ Diameter): The 572 XP starts to show its advantage in this range. Its increased power allows for faster and more efficient cutting, especially when dealing with hardwoods like oak or maple.

• Large Trees (Over 30″ Diameter): The 572 XP is the clear winner for felling large trees. Its extra power is essential for maintaining cutting speed and preventing the saw from bogging down, especially when using a longer bar.

Case Study: I worked on a project in the Pacific Northwest where we were felling Douglas fir trees, some exceeding 40″ in diameter. While the 565 could handle some of the smaller trees, the 572 XP was the go-to saw for the larger ones. The 572 XP’s ability to pull a longer bar through the dense wood was crucial for completing the job efficiently.

Limbing

• Both saws are suitable for limbing. The lighter weight of the 565 might be slightly advantageous for extended limbing sessions, but the 572 XP’s extra power can make quick work of larger branches.

Bucking Logs

• Small to Medium Logs (Up to 20″ Diameter): Both saws will perform well.

• Large Logs (Over 20″ Diameter): The 572 XP excels at bucking large logs, especially when cutting firewood. Its extra power allows for faster and more consistent cuts, reducing fatigue and increasing productivity.

My Insight: When bucking large oak logs for firewood, I found that the 572 XP required less effort to maintain a straight cut. The 565, while still capable, required more attention and finesse to prevent the bar from pinching or wandering.

Splitting Firewood

While chainsaws are not directly used for splitting firewood, the size of the logs you can efficiently process with each saw directly impacts your splitting workload.

• Larger Logs = Fewer Splits: The 572 XP’s ability to handle larger logs means you can create larger rounds for splitting, potentially reducing the number of splits required to achieve your desired firewood size.

Tool Tip: I highly recommend using a hydraulic log splitter for processing large quantities of firewood. A 25-ton or larger splitter can handle even the toughest hardwoods with ease, significantly reducing the physical strain of splitting by hand.

Debarking Logs

Debarking logs can be a necessary step for certain wood processing applications, such as preparing logs for milling or building log structures.

• Both saws can be used for debarking, but specialized debarking tools are generally more efficient. However, if you need to remove bark with a chainsaw, the 572 XP’s extra power can be helpful, especially when dealing with thick or stubborn bark.

Choosing the Right Bar Length

Selecting the appropriate bar length is crucial for maximizing the performance and safety of your chainsaw.

• General Rule: Choose the shortest bar length that can handle the largest diameter wood you typically cut.

• 565 Recommended Bar Length: 16″ – 28″

• 572 XP Recommended Bar Length: 16″ – 28″

My Recommendation: While both saws can handle a 28″ bar, I generally recommend using a 20″ or 24″ bar for most applications. This provides a good balance between cutting capacity and maneuverability. If you primarily cut large trees, then a 28″ bar might be necessary.

Important Note: Always ensure that the bar length you choose is appropriate for the type of wood you are cutting. Using a bar that’s too long for the saw’s displacement can strain the engine and reduce cutting efficiency.

Fuel and Oil Considerations

Using the correct fuel and oil mixture is essential for maintaining the performance and longevity of your chainsaw.

• Fuel: Use high-quality gasoline with an octane rating of 89 or higher. Avoid using gasoline that contains ethanol, as it can damage the engine.

• Oil: Use a high-quality two-stroke oil specifically designed for chainsaws. Husqvarna recommends using their XP Synthetic Blend Oil.

• Mixing Ratio: Follow the manufacturer’s recommended mixing ratio, typically 50:1 (gasoline to oil).

My Tip: I always pre-mix my fuel and oil in a separate container to ensure proper mixing. I also add a fuel stabilizer to prevent the fuel from degrading, especially if the saw will be stored for an extended period.

Maintenance and Safety

Proper maintenance and safety practices are paramount when operating a chainsaw.

Maintenance

• Chain Sharpening: Sharpen the chain regularly to maintain optimal cutting performance. A dull chain will increase cutting time, strain the engine, and increase the risk of kickback.

• Air Filter Cleaning: Clean the air filter regularly to ensure proper airflow to the engine. A clogged air filter can reduce power and increase fuel consumption.

• Spark Plug Replacement: Replace the spark plug annually or as needed. A worn spark plug can cause starting problems and reduce engine performance.

• Bar and Chain Lubrication: Ensure that the bar and chain are properly lubricated at all times. Insufficient lubrication can cause the chain to overheat and wear prematurely.

Safety

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including a helmet, safety glasses, hearing protection, chainsaw chaps, gloves, and sturdy boots.

• Kickback Awareness: Be aware of the risk of kickback, which occurs when the tip of the bar comes into contact with an object, causing the saw to suddenly jump back towards the operator.

• Proper Stance and Grip: Maintain a stable stance and grip the saw firmly with both hands.

• Clear Work Area: Ensure that the work area is clear of obstacles and bystanders.

• Never Cut Above Shoulder Height: Avoid cutting above shoulder height, as this increases the risk of losing control of the saw.

My Safety Story: I once witnessed a logger suffer a serious leg injury due to kickback. He was cutting a small branch and failed to maintain a proper grip on the saw. Fortunately, he was wearing chainsaw chaps, which significantly reduced the severity of the injury. This incident served as a stark reminder of the importance of always following safety precautions.
