Understanding the Allure of the 28-Inch Bar: When Length Matters

Why consider a 28-inch bar for your Husqvarna chainsaw in the first place? The answer lies in increased versatility and cutting capacity. For years, I primarily used a 20-inch bar on my Husqvarna 455 Rancher. It was perfect for smaller trees and general firewood processing. However, when I started tackling larger diameter logs – over 24 inches – I found myself constantly repositioning the saw, making the work slower and more tiring. That’s when I started exploring longer bar options.

A 28-inch bar offers several advantages:

• Increased Felling Capacity: You can fell trees with larger diameters in a single pass, reducing the need for complex cuts and minimizing the risk of kickback.
• Efficient Log Processing: Bucking large logs into manageable pieces becomes significantly easier and faster.
• Reduced Strain: Less bending and awkward positioning when processing large timber translates to less physical strain on your body.

However, a longer bar isn’t a universal solution. It also comes with potential drawbacks:

• Increased Weight: A longer bar adds weight to the saw, potentially making it more difficult to handle, especially for extended periods.
• Reduced Maneuverability: Navigating tight spaces or performing intricate cuts becomes more challenging.
• Increased Power Demand: A longer bar requires more power to drive the chain, potentially straining the engine and reducing cutting speed if the saw is underpowered.
• Higher Kickback Risk: Longer bars, if not handled carefully, can increase the risk of kickback.

Before committing to a 28-inch bar, carefully assess your needs and the capabilities of your chainsaw.

Assessing Your Husqvarna Chainsaw: Is It Up to the Task?

Not all Husqvarna chainsaws are created equal. A 28-inch bar demands a certain level of power and performance. I learned this the hard way when I initially tried putting a 24-inch bar on an underpowered saw – the results were underwhelming, to say the least.

Here’s a checklist to determine if your Husqvarna chainsaw is suitable for a 28-inch bar upgrade:

• Engine Displacement: As a general rule, chainsaws with engine displacements of 50cc or higher are better suited for longer bars. Models like the Husqvarna 455 Rancher, 460 Rancher, 555, 562 XP, and similar professional-grade saws are good candidates.
• Horsepower: Look for chainsaws with at least 3.5 horsepower. This provides sufficient power to drive the chain through dense wood.
• Bar Mount Compatibility: Ensure that the 28-inch bar you choose is compatible with your chainsaw’s bar mount. Husqvarna uses various bar mount patterns; consult your owner’s manual or a chainsaw parts supplier to confirm compatibility.
• Chain Pitch and Gauge: The bar, chain, and sprocket must all match in terms of pitch and gauge. Common combinations include .325″ pitch with .058″ gauge, or 3/8″ pitch with .050″ or .058″ gauge.
• Sprocket Condition: Inspect your chainsaw’s sprocket. A worn or damaged sprocket can cause chain slippage and uneven wear, especially with a longer bar. Replace the sprocket if necessary.

Data Point: A study by the Forest Engineering Research Institute of Canada (FERIC) found that using the correct bar length for the task at hand can increase productivity by up to 20% and reduce operator fatigue by 15%.

Personal Experience: I upgraded my Husqvarna 455 Rancher (55.5cc) with a 28-inch bar, and while it handled the longer bar reasonably well, I noticed a slight decrease in cutting speed compared to my Husqvarna 562 XP (59.8cc) with the same bar. The 562 XP had noticeably more torque and power, making it a better match for the longer bar.

Decoding Bar Specifications: Pitch, Gauge, and Drive Links

Before you rush out and buy a 28-inch bar, it’s crucial to understand the key specifications that determine compatibility with your chainsaw and chain. I remember the confusion I felt when I first encountered these terms, so let’s break them down.

• Pitch: The pitch is the distance between any three consecutive rivets on the chain, divided by two. It’s typically measured in inches (e.g., .325″, 3/8″). The pitch of the bar must match the pitch of the chain and sprocket.
• Gauge: The gauge is the thickness of the drive links that fit into the groove of the bar. It’s also measured in inches (e.g., .050″, .058″, .063″). Again, the bar, chain, and sprocket must all have the same gauge.
• Drive Links: The number of drive links refers to the number of links on the chain that fit into the bar’s groove and are driven by the sprocket. The 28-inch bar will require a specific number of drive links depending on the pitch and gauge.

How to Determine the Correct Specifications:

1. Consult Your Owner’s Manual: The owner’s manual for your Husqvarna chainsaw will specify the recommended pitch, gauge, and drive link count for various bar lengths.
2. Check the Existing Bar: If you’re replacing an existing bar, the specifications are usually stamped on the bar itself, near the mounting end.
3. Use an Online Bar and Chain Selector: Many chainsaw parts suppliers offer online tools that allow you to input your chainsaw model and bar length to find compatible chains.
4. Consult a Chainsaw Technician: If you’re unsure, it’s always best to consult a qualified chainsaw technician for guidance.

Example: A 28-inch bar with a .325″ pitch and .058″ gauge typically requires 93 drive links. A 28-inch bar with a 3/8″ pitch and .050″ gauge usually requires 92 drive links.

Caution: Using a chain with the wrong pitch or gauge can damage the bar, chain, and sprocket, and can even lead to dangerous kickback.

Choosing the Right 28-Inch Bar: Brands, Types, and Features

With the technical specifications understood, let’s explore the different types of 28-inch bars available for your Husqvarna chainsaw. Here are some key considerations:

• Brand: Husqvarna offers its own line of bars, known for their quality and durability. Other reputable brands include Oregon, Stihl (compatible with Husqvarna with the correct mount), and Tsumura.
• Bar Type:
  • Laminated Bars: These are the most common type of bar, consisting of multiple layers of steel welded together. They are relatively lightweight and affordable.
  • Solid Bars: Made from a single piece of steel, solid bars are more durable and resistant to bending. They are typically used in professional logging applications.
  • Hard Nose Bars: These bars have a hardened tip for increased wear resistance, particularly useful when cutting dirty or abrasive wood.
  • Sprocket Nose Bars: These bars have a sprocket at the tip, which reduces friction and heat buildup, resulting in smoother and faster cutting.
• Features:
  • Replaceable Sprocket Nose: Allows you to replace the sprocket nose when it wears out, extending the life of the bar.
  • Lubri-Dam: A feature that helps retain oil on the bar and chain, reducing friction and wear.
  • Inlaid Armor: Some bars feature inlaid armor plating for added durability and resistance to abrasion.

Recommendations:

• For occasional use and general firewood processing: A laminated bar from Husqvarna or Oregon is a good choice.
• For heavy-duty use and professional logging: A solid bar from Tsumura or Husqvarna is recommended.
• For cutting dirty or abrasive wood: A hard nose bar is a good option.
• For smoother and faster cutting: A sprocket nose bar can improve performance.

Cost-Benefit Analysis: While a solid bar is more expensive than a laminated bar, its increased durability and longer lifespan can make it a worthwhile investment for frequent users. Similarly, a replaceable sprocket nose can save you money in the long run by allowing you to replace the sprocket nose instead of the entire bar.

The Expert Fit Guide: Installing Your 28-Inch Bar

Now, let’s get to the heart of the matter: installing your new 28-inch bar. This process is relatively straightforward, but it’s crucial to follow the steps carefully to ensure proper fit and safe operation. I’ve seen too many people rush this process, leading to chain derailment, bar damage, and even injuries.

Tools You’ll Need:

• Chainsaw wrench (usually included with your Husqvarna chainsaw)
• Screwdriver (for adjusting chain tension)
• Gloves
• Clean rag
• Bar oil

Step-by-Step Installation:

1. Turn Off and Disconnect the Chainsaw: Ensure the chainsaw is switched off and the spark plug wire is disconnected to prevent accidental starting.
2. Remove the Side Cover: Use the chainsaw wrench to loosen and remove the nuts holding the side cover in place. Carefully remove the side cover, exposing the bar and chain.
3. Remove the Old Bar and Chain: Loosen the chain tensioning screw to allow the chain to slacken. Remove the chain from the bar groove and then remove the bar from the chainsaw.
4. Clean the Bar Mount: Use a clean rag to remove any dirt, debris, or old oil from the bar mount area on the chainsaw. This ensures a clean and secure fit for the new bar.
5. Install the New Bar: Align the bar mount holes on the new 28-inch bar with the studs on the chainsaw. Slide the bar onto the studs, ensuring it sits flush against the bar mount.
6. Install the Chain: Place the chain around the sprocket on the chainsaw and then carefully guide the drive links into the groove of the bar. Ensure the cutting edges of the chain are facing the correct direction (usually indicated by arrows on the chain).
7. Install the Side Cover: Align the chain tensioning pin on the side cover with the corresponding hole on the bar. Reinstall the side cover and tighten the nuts finger-tight.
8. Adjust Chain Tension: Use the chain tensioning screw to adjust the chain tension. The chain should be snug against the bar but still able to be pulled around the bar by hand. A properly tensioned chain will have about 1/8″ to 1/4″ of sag on the bottom of the bar.
9. Tighten the Side Cover Nuts: Once the chain tension is properly adjusted, tighten the side cover nuts securely with the chainsaw wrench.
10. Check Chain Lubrication: Start the chainsaw and check that the chain is receiving adequate lubrication. You should see a fine spray of oil coming off the chain as it rotates. Adjust the oiler setting if necessary.

Important Considerations:

• Chain Direction: Always ensure the chain is installed with the cutting edges facing the correct direction. Installing the chain backward will result in no cutting and can damage the chain and bar.
• Chain Tension: Proper chain tension is crucial for safe and efficient operation. A chain that is too tight can overheat and break, while a chain that is too loose can derail and cause kickback.
• Bar Oiler: Regularly check the bar oil level and ensure the oiler is functioning properly. Insufficient lubrication can lead to premature wear of the bar and chain.

Troubleshooting:

• Chain Derailment: If the chain keeps derailing, check the chain tension, bar groove, and sprocket for wear or damage. Also, ensure the chain is properly seated in the bar groove.
• Uneven Cutting: Uneven cutting can be caused by a dull chain, a damaged bar, or improper chain tension. Sharpen the chain, inspect the bar for damage, and adjust the chain tension as needed.
• Overheating: Overheating can be caused by insufficient lubrication, a dull chain, or excessive chain tension. Check the bar oil level, sharpen the chain, and adjust the chain tension.

Mastering Chainsaw Techniques with a 28-Inch Bar: Safety First

With your 28-inch bar installed, it’s time to focus on mastering the techniques for safe and efficient operation. A longer bar requires a different approach than a shorter bar, and it’s crucial to understand the nuances to avoid accidents. I’ve witnessed firsthand the consequences of complacency, and I can’t stress enough the importance of prioritizing safety.

Essential Safety Gear:

• Chainsaw Helmet: Protects your head from falling debris and potential kickback.
• Eye Protection: Safety glasses or a face shield are essential to protect your eyes from flying wood chips.
• Hearing Protection: Chainsaws are loud, and prolonged exposure to noise can damage your hearing. Wear earplugs or earmuffs.
• Chainsaw Gloves: Provide grip and protection for your hands.
• Chainsaw Chaps: Protect your legs from accidental contact with the chain.
• Steel-Toed Boots: Protect your feet from falling logs and sharp objects.

Felling Techniques:

• Assess the Tree: Before felling a tree, carefully assess its size, lean, and any potential hazards such as dead branches or power lines.
• Plan Your Escape Route: Identify a clear escape route that is at a 45-degree angle away from the direction of the fall.
• Make the Notch Cut: The notch cut determines the direction of the fall. It should be made at a 70-degree angle, with the bottom cut slightly deeper than the top cut.
• Make the Back Cut: The back cut should be made on the opposite side of the tree from the notch cut, slightly above the bottom of the notch. Leave a hinge of wood to control the fall of the tree.
• Use Wedges: If the tree is leaning in the wrong direction, use wedges to help guide its fall.
• Yell “Timber!”: Warn anyone in the area before the tree falls.

Bucking Techniques:

• Support the Log: When bucking logs, ensure they are properly supported to prevent them from pinching the bar. Use log jacks or other supports to elevate the log off the ground.
• Avoid Pinching: Be aware of the potential for pinching, which occurs when the weight of the log closes the kerf (the cut made by the chainsaw) and traps the bar. Use wedges to keep the kerf open.
• Cut from the Top or Bottom: Depending on the situation, you may need to cut from the top or bottom of the log to avoid pinching.
• Use Proper Posture: Maintain a stable stance and avoid bending over excessively. Use your legs to lift and move logs.

Kickback Prevention:

• Be Aware of the Kickback Zone: The kickback zone is the upper quadrant of the bar tip. Avoid contacting this area with the wood.
• Maintain a Firm Grip: Hold the chainsaw firmly with both hands, keeping your thumbs wrapped around the handles.
• Keep the Chain Sharp: A dull chain is more likely to kick back. Sharpen the chain regularly.
• Use a Reduced-Kickback Chain: Consider using a reduced-kickback chain, which has guard links that help prevent the chain from grabbing and kicking back.
• Avoid Plunge Cutting: Plunge cutting, which involves inserting the bar tip directly into the wood, is a high-risk activity for kickback.

Data Point: According to the Consumer Product Safety Commission (CPSC), approximately 36,000 chainsaw-related injuries are treated in U.S. emergency rooms each year. Most of these injuries are preventable with proper safety precautions.

Case Study: I once witnessed a fellow woodcutter suffer a severe kickback injury while felling a tree with a dull chain. He contacted the kickback zone with the bar tip, and the chainsaw kicked back violently, striking him in the face. He was fortunate to be wearing a helmet and face shield, which prevented a more serious injury. This incident served as a stark reminder of the importance of maintaining sharp chains and being aware of the kickback zone.

Wood Science for the Chainsaw User: Understanding Wood Properties

To truly master wood processing, it’s essential to understand the properties of wood itself. Different species of wood have different densities, grain patterns, and moisture contents, all of which affect how they cut and split. I’ve spent years studying wood science, and I’m constantly amazed by the complexity and variability of this natural material.

Hardwood vs. Softwood:

• Hardwoods: Typically deciduous trees with broad leaves, such as oak, maple, and ash. Hardwoods are generally denser and more difficult to cut than softwoods.
• Softwoods: Typically coniferous trees with needles, such as pine, fir, and spruce. Softwoods are generally less dense and easier to cut than hardwoods.

Grain Patterns:

• Straight Grain: Wood with straight, parallel grain is easier to split and work with.
• Interlocked Grain: Wood with interlocked or spiral grain is more difficult to split and can be prone to twisting and warping.
• Knotty Wood: Wood with knots is more difficult to cut and split, as the knots disrupt the grain and create weak spots.

Moisture Content:

• Green Wood: Freshly cut wood has a high moisture content (often over 50%). Green wood is heavier, more difficult to cut, and prone to shrinkage and warping as it dries.
• Seasoned Wood: Wood that has been allowed to dry to a lower moisture content (typically 20% or less) is lighter, easier to cut, and less prone to shrinkage and warping.
• Kiln-Dried Wood: Wood that has been dried in a kiln to a specific moisture content (typically 6-8%) is the most stable and predictable.

Impact of Wood Properties on Chainsaw Use:

• Hardness: Harder woods require more power to cut and can dull the chain more quickly.
• Moisture Content: Green wood is more difficult to cut and can clog the chain. Seasoned wood is easier to cut and produces less sawdust.
• Grain Pattern: Wood with interlocked grain can be prone to binding and kickback.

Tips for Cutting Different Types of Wood:

• Hardwoods: Use a sharp chain and apply steady pressure. Avoid forcing the saw, as this can cause the chain to bind.
• Softwoods: Use a slightly less aggressive chain and avoid overheating the saw.
• Green Wood: Clean the chain frequently to remove sawdust and pitch.
• Knotty Wood: Cut slowly and carefully around knots to avoid kickback.

Data Point: A study by the University of Maine found that the energy required to cut green wood is approximately 50% higher than the energy required to cut seasoned wood.

Firewood Seasoning: Transforming Wood into Fuel

If you’re using your chainsaw to prepare firewood, proper seasoning is crucial for maximizing its heat output and minimizing smoke. Seasoning refers to the process of drying wood to reduce its moisture content. I’ve experimented with various seasoning methods over the years, and I’ve found that a combination of proper stacking, airflow, and sunlight is the key to success.

Benefits of Seasoning Firewood:

• Increased Heat Output: Dry wood burns hotter and more efficiently than green wood.
• Reduced Smoke: Dry wood produces less smoke, which is better for the environment and your chimney.
• Easier to Ignite: Dry wood ignites more easily and burns more consistently.
• Reduced Creosote Buildup: Dry wood produces less creosote, a flammable substance that can accumulate in your chimney and increase the risk of a chimney fire.

Seasoning Techniques:

1. Split the Wood: Splitting the wood exposes more surface area to the air, accelerating the drying process.
2. Stack the Wood Properly: Stack the wood in loose rows, allowing air to circulate freely around each piece.
3. Elevate the Wood: Elevate the wood off the ground to prevent moisture from wicking up from the soil. Use pallets or other supports.
4. Choose a Sunny Location: Place the woodpile in a sunny location to maximize evaporation.
5. Cover the Woodpile (Optional): Covering the top of the woodpile with a tarp or roof can protect it from rain and snow, further accelerating the drying process. However, ensure the sides of the woodpile remain open to allow for airflow.

Seasoning Time:

The time required to season firewood depends on the species of wood, the climate, and the seasoning method. Generally, hardwoods require at least 6-12 months to season properly, while softwoods may season in as little as 3-6 months.

Measuring Moisture Content:

You can use a moisture meter to measure the moisture content of your firewood. A moisture content of 20% or less is ideal for burning.

Signs of Properly Seasoned Firewood:

• Cracks in the End Grain: Properly seasoned firewood will have cracks in the end grain.
• Lighter Weight: Seasoned firewood will be significantly lighter than green wood.
• Dull Sound: When struck together, seasoned firewood will produce a dull, hollow sound, while green wood will produce a solid thud.
• Grayish Color: Seasoned firewood will have a grayish color, while green wood will be more vibrant.

Data Point: A study by the Biomass Energy Resource Center found that burning properly seasoned firewood can increase heat output by up to 50% compared to burning green wood.

Personal Story: I once made the mistake of burning unseasoned firewood in my wood stove. The fire was difficult to start, produced a lot of smoke, and barely generated any heat. My chimney quickly became coated in creosote, and I had to hire a chimney sweep to clean it. I learned my lesson the hard way – proper seasoning is essential for safe and efficient firewood burning.

Maintenance and Longevity: Caring for Your 28-Inch Bar

To ensure the longevity and performance of your 28-inch bar, regular maintenance is essential. A well-maintained bar will cut more efficiently, reduce the risk of chain derailment, and last longer. I’ve seen bars neglected to the point of uselessness, and it’s a sad waste of a valuable tool.

Regular Maintenance Tasks:

• Clean the Bar Groove: Use a bar groove cleaner or a screwdriver to remove sawdust and debris from the bar groove. A clogged bar groove can restrict oil flow and cause the chain to overheat.
• Check the Bar Rails: Inspect the bar rails for wear or damage. If the rails are uneven or damaged, the chain may not track properly. Use a bar rail dresser to file the rails back to a smooth, even surface.
• File Down Burrs: Use a flat file to remove any burrs or sharp edges from the bar rails. Burrs can damage the chain and cause it to derail.
• Lubricate the Bar: Apply bar oil to the bar regularly, especially after each use. Proper lubrication reduces friction and wear.
• Store the Bar Properly: When not in use, store the bar in a dry place to prevent rust and corrosion. Consider using a bar scabbard to protect the bar from damage.

Bar Rail Dressing:

Bar rail dressing is the process of filing the bar rails to restore them to a smooth, even surface. This is essential for maintaining proper chain tracking and preventing chain derailment.

Steps for Dressing Bar Rails:

1. Clean the Bar: Clean the bar thoroughly to remove any dirt, debris, or old oil.
2. Inspect the Rails: Inspect the bar rails for wear or damage. Identify any areas that are uneven or have burrs.
3. Use a Bar Rail Dresser: Use a bar rail dresser to file the rails back to a smooth, even surface. Follow the angle of the rails and apply even pressure.
4. Check for Squareness: Use a square to check that the rails are square to the bar. If the rails are not square, continue filing until they are.
5. File Down Burrs: Use a flat file to remove any burrs or sharp edges from the bar rails.
6. Lubricate the Bar: Apply bar oil to the bar after dressing the rails.

Signs That Your Bar Needs Replacement:

• Excessive Wear: If the bar rails are worn down to the point where the chain no longer tracks properly, it’s time to replace the bar.
• Bent or Damaged Bar: If the bar is bent or damaged, it can be dangerous to use and should be replaced.
• Cracked Bar: If the bar is cracked, it can fail under stress and should be replaced immediately.

Data Point: A well-maintained chainsaw bar can last for hundreds of hours of use, while a neglected bar may only last for a fraction of that time.
