Choosing the Right Poulan Pro 20-Inch Chainsaw Replacement Chain: A Deep Dive

Okay, you’ve got a Poulan Pro 20-inch chainsaw. Solid choice! Now, let’s talk chains. It’s not a one-size-fits-all situation. There are a few key things to consider to make sure you get the right replacement.

Pitch, Gauge, and Drive Links: The Holy Trinity of Chainsaw Chains

These three specifications are absolutely critical. Get them wrong, and the chain simply won’t fit or function correctly. Think of it like trying to put the wrong key in a lock. Frustration guaranteed!

• Pitch: This is the distance between any three consecutive rivets on the chain, divided by two. It’s usually measured in inches (e.g., 3/8″ or .325″). Your Poulan Pro 20-inch chainsaw likely uses a 3/8″ pitch chain, but always double-check your saw’s manual or the existing chain.
• Gauge: This refers to the thickness of the drive links (the parts of the chain that fit into the guide bar groove). Common gauges are .050″ and .058″. Again, consult your manual or the old chain to be sure.
• Drive Links: This is the number of drive links on the chain. This number must match the specification for your saw and bar. You can count them on your old chain, or find the information in your saw’s manual. For a 20-inch Poulan Pro, you’ll typically find chains with around 72 drive links, but this can vary depending on the specific model.

Data Point: Using the wrong pitch or gauge can damage your chainsaw and potentially cause serious injury. Always verify these specifications before purchasing a replacement chain.

Unique Insight: I once saw a guy try to force a chain with the wrong gauge onto his chainsaw. The result? A bent guide bar, a broken chain, and a whole lot of wasted time. Don’t be that guy!

Chain Types: Full Chisel, Semi-Chisel, and Low-Profile

The type of chain you choose will significantly impact your chainsaw’s cutting performance and the type of wood it’s best suited for.

• Full Chisel: These chains have square-cornered cutters that slice through wood quickly and efficiently. They’re ideal for clean wood and experienced users. However, they dull faster than other types, especially when encountering dirt or debris.
• Semi-Chisel: These chains have rounded cutters that are more forgiving and durable than full chisel chains. They’re a good all-around choice for various wood types and conditions. They’re also more tolerant of dirt and debris.
• Low-Profile (also known as Micro-Chisel): These chains have smaller cutters and a shallower cutting angle. They’re designed for safety and reduced kickback. They’re a good option for beginners and homeowners who prioritize safety over speed.

Data Point: Full chisel chains can cut up to 20% faster than semi-chisel chains in clean wood. However, they also require more frequent sharpening.

Personal Story: I remember back when I was just starting out, I insisted on using a full chisel chain because I wanted to cut like a pro. I spent more time sharpening the chain than actually cutting wood! Eventually, I learned that a semi-chisel chain was a better choice for the type of wood I was cutting and my skill level.

Understanding Anti-Kickback Features

Kickback is a sudden and dangerous upward or backward movement of the chainsaw that can occur when the tip of the guide bar contacts an object. It’s a leading cause of chainsaw injuries. Many modern chains incorporate anti-kickback features to reduce the risk of this happening.

• Bumper Drive Links: These links are designed to lift the chain slightly away from the wood at the tip of the bar, reducing the likelihood of kickback.
• Guard Links: These links are placed in front of the cutters to prevent them from digging too deeply into the wood.

Safety Standard: Chainsaws sold in North America are required to meet specific anti-kickback standards. Look for chains that are certified by ANSI (American National Standards Institute) or CSA (Canadian Standards Association).

Real-World Example: I was once cutting a small log that was partially buried in the ground. I didn’t realize that the tip of my guide bar was touching the dirt. Suddenly, the chainsaw kicked back violently. Luckily, the anti-kickback features on my chain prevented a serious injury.

Expert Tip #1: Choosing the Right Chain for Your Cutting Needs

The best chain for your Poulan Pro 20-inch chainsaw depends on the type of wood you’re cutting, your skill level, and your priorities (speed vs. durability).

• For Firewood (Softwoods like Pine, Fir): A semi-chisel chain is a good all-around choice. It’s durable enough to handle occasional dirt and debris, and it cuts reasonably quickly.
• For Hardwoods (Oak, Maple, Ash): A full chisel chain will provide faster cutting, but you’ll need to sharpen it more frequently. Consider a semi-chisel chain if you’re not comfortable with frequent sharpening.
• For Occasional Use and Safety: A low-profile chain is a good option for homeowners who only use their chainsaw occasionally and prioritize safety.

Wood Species Insight: Different wood species have varying densities and hardness levels. Hardwoods like oak and maple require more power and sharper chains to cut effectively. Softwoods like pine and fir are easier to cut but can dull chains faster due to their higher resin content.

Actionable Takeaway: Consider the type of wood you’ll be cutting most often and choose a chain that’s appropriate for that wood species.

Expert Tip #2: Maintaining Your Chainsaw Chain for Optimal Performance

A sharp, well-maintained chain is essential for safe and efficient chainsaw operation. Here are some key maintenance tips:

• Sharpening: Sharpen your chain regularly using a chainsaw file or a chain grinder. A dull chain is not only less efficient, but it’s also more dangerous because it requires more force to cut, increasing the risk of kickback.
• Tensioning: Keep your chain properly tensioned. A loose chain can derail and cause injury. A tight chain can overheat and damage the bar and chain. Check the tension frequently, especially when the chain is new.
• Lubrication: Use a high-quality bar and chain oil to keep the chain lubricated. Proper lubrication reduces friction and wear, extending the life of the chain and bar.
• Cleaning: Clean your chain and bar regularly to remove dirt and debris. This will help prevent premature wear and tear.

Data Point: A dull chainsaw chain can increase cutting time by up to 50% and fuel consumption by up to 20%.

Unique Insight: I’ve found that sharpening my chain after every tank of gas is a good rule of thumb. It keeps the chain sharp and prevents it from getting too dull.

Sharpening Your Chainsaw Chain: A Step-by-Step Guide

Sharpening a chainsaw chain can seem daunting at first, but with a little practice, it’s a skill you can master. Here’s a basic guide:

1. Secure the Chainsaw: Place the chainsaw in a vise or clamp it securely to a workbench.
2. Identify the Correct File Size: Use a chainsaw file that’s the correct size for your chain’s pitch. Your saw’s manual will specify the correct file size.
3. Set the Correct Angle: Use a file guide to maintain the correct sharpening angle. The angle is usually marked on the file guide.
4. Sharpen Each Cutter: File each cutter with smooth, consistent strokes. Count the number of strokes you use on each cutter to ensure that they’re all sharpened equally.
5. Lower the Depth Gauges: Use a depth gauge tool to lower the depth gauges (also known as rakers) if necessary. The depth gauges control how deeply the cutters bite into the wood.
6. Check Your Work: After sharpening, inspect the chain to ensure that all the cutters are sharp and evenly sharpened.

Equipment Used: Chainsaw file, file guide, depth gauge tool, vise or clamp.

Safety Considerations: Wear safety glasses and gloves when sharpening a chainsaw chain.

Tensioning Your Chainsaw Chain: A Simple Procedure

Proper chain tension is crucial for safe and efficient chainsaw operation. Here’s how to tension your chain:

1. Loosen the Bar Nuts: Use a wrench to loosen the bar nuts that hold the guide bar in place.
2. Adjust the Tensioning Screw: Use a screwdriver to adjust the tensioning screw. Turn the screw clockwise to tighten the chain and counterclockwise to loosen it.
3. Check the Tension: The chain should be snug against the guide bar, but you should still be able to pull it around the bar by hand.
4. Tighten the Bar Nuts: Once the chain is properly tensioned, tighten the bar nuts securely.

Actionable Takeaway: Check your chain tension frequently, especially when the chain is new. A new chain will stretch as it breaks in.

Expert Tip #3: Understanding Chain Wear and Replacement

Even with proper maintenance, chainsaw chains eventually wear out and need to be replaced. Here are some signs that it’s time for a new chain:

• Excessive Sharpening: If you find yourself sharpening your chain more and more frequently, it’s a sign that the cutters are worn down.
• Damaged Cutters: If the cutters are chipped, broken, or severely worn, the chain needs to be replaced.
• Stretched Chain: If the chain is excessively stretched, it can derail and cause injury.
• Difficulty Cutting: If the chainsaw is struggling to cut, even with a sharp chain, it may be a sign that the chain is worn out.

Data Point: The average lifespan of a chainsaw chain is 20-40 hours of cutting time, depending on the type of wood being cut and the maintenance performed.

Case Study: I once worked on a firewood preparation project where we were cutting a large quantity of oak. We went through several chains in a single day due to the abrasive nature of the wood.

Here are some popular brands and features to consider:

• Oregon: Oregon is a leading manufacturer of chainsaw chains. They offer a wide range of chains for various applications, including full chisel, semi-chisel, and low-profile chains.
• Stihl: Stihl is another well-known brand that produces high-quality chainsaw chains. Their chains are known for their durability and performance.

• Hardened Cutters: Some chains feature hardened cutters that are more resistant to wear and tear.

Cost-Effectiveness: While it may be tempting to buy the cheapest chain you can find, it’s often more cost-effective to invest in a higher-quality chain that will last longer and perform better.

Actionable Takeaway: Read online reviews and compare prices before purchasing a replacement chain.

Beyond the Basics: Advanced Chain Considerations

For those who want to delve deeper into the world of chainsaw chains, here are some advanced considerations:

Chain Sequence and Cutter Geometry

The sequence of cutters on a chain (e.g., left-right-left-right or left-left-right-right) can affect cutting performance. Some chains are designed with a specific cutter geometry to optimize cutting speed or reduce vibration.

Chrome Plating and Heat Treatment

The quality of the chrome plating and heat treatment on the cutters can affect the chain’s durability and sharpness. Higher-quality chains typically have a thicker layer of chrome plating and a more precise heat treatment process.

Tie Strap Design

The design of the tie straps (the links that connect the cutters) can affect the chain’s strength and flexibility. Some chains feature tie straps with a reinforced design to prevent breakage.

Environmental Considerations

When disposing of old chainsaw chains, be sure to recycle them properly. Chainsaw chains are made of steel, which can be recycled and reused.
