Why I’m Obsessed with This Upgrade (and Why You Should Be Too)

There’s a certain satisfaction that comes from taking down a sizable tree with a tool that feels perfectly balanced and powerful. For me, that feeling started with a Husqvarna 435. It was my gateway into the world of professional woodcutting. I quickly found that the standard bar length was limiting me. I was constantly reaching the chainsaw’s maximum cutting capacity, especially when dealing with larger diameter logs. That’s when I started experimenting with longer bars.

The 18-inch bar on the 435 isn’t just about cutting bigger trees. It’s about efficiency. Fewer cuts to fell a tree, faster bucking of logs, and reduced strain on your body. It’s about making the most of your time and energy. And let’s be honest, it looks pretty darn cool too.

2. Understanding the Husqvarna 435 and the 18-Inch Bar: A Deep Dive

Before we dive into the upgrade, let’s establish a solid foundation. We need to understand the Husqvarna 435’s capabilities and the implications of adding a longer bar.

2.1. The Husqvarna 435: A Profile

The Husqvarna 435 is a popular choice for homeowners and occasional users due to its:

Engine Size: Typically around 40.9cc. This is important because it determines the chainsaw’s power output.
Weight: Relatively lightweight, making it easier to handle for extended periods.
Price Point: Affordable, making it accessible to a wide range of users.
Ease of Use: User-friendly design and simple controls.

However, it’s crucial to remember that the 435 is designed for light to medium-duty tasks. Overloading it can lead to premature wear and tear, and more importantly, dangerous situations.

2.2. The 18-Inch Bar: Power and Reach

An 18-inch bar offers several advantages over the standard bar length:

Increased Cutting Capacity: You can fell larger diameter trees and buck thicker logs without having to make multiple cuts.
Improved Reach: The longer bar allows you to reach branches and logs that would otherwise be inaccessible.
Enhanced Leverage: The added length can provide more leverage when felling trees, making the process easier and more controlled.

2.3. The Catch: Matching Bar Length to Engine Power

Here’s the crucial point: The Husqvarna 435’s 40.9cc engine has a limit. It is not designed to pull an 18-inch bar through hardwood all day long. The stock bar is designed to provide optimal torque and speed. Adding an 18-inch bar will increase the load on the engine, and if not properly managed, will:

Reduce Chain Speed: This can lead to slower cutting and increased risk of kickback.
Overheat the Engine: Excessive strain can cause the engine to overheat, leading to damage and reduced lifespan.
Increase Fuel Consumption: The engine will have to work harder to turn the longer bar, resulting in higher fuel consumption.

3. Pro Tip #1: Safety First – A Non-Negotiable Checklist

Safety isn’t just a suggestion; it’s the cornerstone of any successful and enjoyable woodcutting experience. Before you even think about touching that 18-inch bar, make sure you’ve covered all your bases.

3.1. Personal Protective Equipment (PPE): Your Armor

Helmet: With face shield and ear protection. This is your first line of defense against flying debris and noise.
Eye Protection: Even with a face shield, wear safety glasses or goggles.
Hearing Protection: Prolonged exposure to chainsaw noise can cause permanent hearing damage. Use earplugs or earmuffs with a noise reduction rating (NRR) of at least 25 dB.
Gloves: Heavy-duty work gloves protect your hands from cuts, abrasions, and vibrations.
Chainsaw Chaps: These are essential for protecting your legs from accidental cuts. They’re made of ballistic nylon that jams the chain if it comes into contact.
Steel-Toed Boots: Protect your feet from falling logs and accidental drops.

3.2. Chainsaw Inspection: Pre-Flight Check

Before each use, meticulously inspect your Husqvarna 435:

Chain Tension: The chain should be snug but still able to be pulled around the bar by hand.
Chain Sharpness: A dull chain is a dangerous chain. Sharpen it before each use.
Bar Condition: Check for wear, damage, and proper lubrication.
Throttle Trigger and Interlock: Ensure they function smoothly and properly.
Chain Brake: Verify that the chain brake engages and disengages correctly.
Fuel and Oil Levels: Top off both fuel and chain oil before starting.

3.3. Work Area Assessment: Clearing the Deck

Clear Obstacles: Remove any rocks, branches, or other debris from the area where you’ll be working.
Plan Your Escape Route: Identify a clear path away from the tree in case of a fall.
Check for Overhead Hazards: Be aware of any dead or hanging branches that could fall during the felling process.
Inform Others: Let someone know where you’ll be working and when you expect to be finished.

3.4. The Buddy System: Safety in Numbers

Whenever possible, work with a partner. Having someone nearby can be invaluable in case of an emergency.

4. Pro Tip #2: Chain Selection and Sharpening – The Keys to Efficient Cutting

With the 18-inch bar installed, your chain becomes even more important. The right chain, properly sharpened, will make all the difference in performance and safety.

4.1. Chain Type: Matching the Chain to the Task

Low-Kickback Chains: These chains are designed to reduce the risk of kickback, a sudden and violent upward movement of the chainsaw. These are good for beginners, but slower.
Full-Chisel Chains: These chains have square-cornered teeth that provide aggressive cutting performance. Ideal for experienced users.
Semi-Chisel Chains: A compromise between low-kickback and full-chisel chains, offering a good balance of safety and performance.

For the Husqvarna 435 with an 18-inch bar, I generally recommend a semi-chisel chain. It provides a good balance of cutting speed and durability. However, if you’re new to chainsaws, a low-kickback chain is a safer option.

4.2. Chain Pitch and Gauge: Ensuring Compatibility

Pitch: The distance between three consecutive rivets on the chain, divided by two. Common pitches are .325″ and 3/8″.
Gauge: The thickness of the drive links that fit into the bar groove. Common gauges are .050″ and .058″.

It’s absolutely crucial to use a chain with the correct pitch and gauge for your Husqvarna 435 and 18-inch bar. Consult your owner’s manual or a reputable chainsaw dealer to determine the correct specifications.

4.3. Sharpening: The Art of Maintaining a Razor Edge

A sharp chain is a safe chain. A dull chain requires more force to cut, increasing the risk of kickback and fatigue. Here’s how to keep your chain sharp:

Tools: You’ll need a round file, a flat file, a file guide, and a depth gauge tool.
Technique: Follow the manufacturer’s instructions for sharpening your specific chain type. Pay attention to the correct filing angle and depth.
Frequency: Sharpen your chain after every few tanks of fuel, or more often if you notice it’s becoming dull.

4.4. My Sharpening Ritual:

I’ve developed a routine over the years that keeps my chains in top condition. I use a Stihl 2-in-1 Easy File. This tool allows me to sharpen the cutters and lower the rakers at the same time. I also use a depth gauge tool to ensure that the rakers are at the correct height. I find that this combination of tools and techniques keeps my chains sharp and cutting efficiently.

5. Pro Tip #3: Carburetor Adjustment – Fine-Tuning for Optimal Performance

With the longer bar, your Husqvarna 435’s engine will be working harder. Proper carburetor adjustment is essential to ensure it runs smoothly and efficiently.

5.1. Understanding the Carburetor Screws:

L (Low-Speed): Controls the fuel mixture at idle and low speeds.
H (High-Speed): Controls the fuel mixture at high speeds.
T (Idle Speed): Adjusts the engine’s idle speed.

5.2. The Tuning Process:

Warm-Up: Start the chainsaw and let it warm up for a few minutes.
Idle Speed Adjustment: Adjust the “T” screw until the chain is not moving at idle.
Low-Speed Adjustment: Turn the “L” screw until the engine idles smoothly and accelerates without hesitation.
High-Speed Adjustment: This is the trickiest part. You want to adjust the “H” screw so that the engine runs at its maximum power without running lean (too little fuel). A lean engine will sound “screechy” and can overheat. A rich engine (too much fuel) will sound “gurgly” and produce excessive smoke.

Important Note: Carburetor adjustment can be tricky. If you’re not comfortable doing it yourself, take your chainsaw to a qualified technician.

5.3. Listening to Your Engine:

The key to successful carburetor adjustment is listening to your engine. A well-tuned engine will sound smooth and powerful, with a crisp throttle response. If the engine sounds rough, hesitant, or excessively smoky, it’s time to make adjustments.

5.4. My Personal Carburetor Tuning Philosophy:

I always err on the side of a slightly richer mixture. A slightly rich engine may produce a little more smoke, but it’s less likely to overheat and cause damage. I’d rather sacrifice a little bit of power for increased engine longevity.

6. Pro Tip #4: Mastering Cutting Techniques – Minimizing Strain, Maximizing Control

The 18-inch bar changes the dynamics of your chainsaw. It’s longer and heavier, which means you need to adjust your cutting techniques to maintain control and minimize strain.

6.1. Felling Techniques:

Directional Felling: Plan your cut carefully to ensure the tree falls in the desired direction. Use a felling wedge to help guide the tree.
Hinge Wood: Leave a hinge of wood on the back of the tree to control its fall.
Back Cut: Make the back cut slightly above the level of the felling cut.

6.2. Bucking Techniques:

Support the Log: Use logs or wedges to support the log you’re cutting.
Avoid Pinching: Be aware of the potential for the bar to become pinched in the cut. Use wedges to keep the cut open.
Cut from Above or Below: Choose the cutting position that minimizes the risk of pinching.

6.3. Body Positioning:

Keep a Wide Stance: Maintain a stable base with your feet shoulder-width apart.
Bend at the Knees: Avoid bending at the waist, which can strain your back.
Keep the Chainsaw Close to Your Body: This will give you more control and reduce fatigue.

6.4. Avoiding Kickback:

Be Aware of the Kickback Zone: The upper quadrant of the bar tip is the kickback zone. Avoid contact with this area.
Maintain a Firm Grip: Keep a firm grip on the chainsaw with both hands.
Use a Low-Kickback Chain: As mentioned earlier, a low-kickback chain can significantly reduce the risk of kickback.
