Chain For Stihl Farm Boss (5 Expert Tips For Optimal Cutting)

As someone who has spent countless hours in the woods, I’ve seen firsthand how technological advancements have revolutionized the way we approach wood processing. From the introduction of lightweight, high-performance chainsaws to the development of sophisticated wood moisture meters, these innovations have not only increased efficiency but also enhanced safety. Today, I want to focus on a crucial component of any chainsaw: the chain. Specifically, we’ll dive into the world of chains designed for the Stihl Farm Boss, a workhorse of a saw that many of us rely on.

Understanding Chain Types and Their Applications

Before we dive into specific tips, let’s take a moment to understand the different types of chainsaw chains available. The type of chain you choose can significantly impact your saw’s performance and the quality of your cuts.

Full Chisel Chains

Full chisel chains are known for their aggressive cutting action. They feature square-cornered teeth that slice through wood quickly and efficiently. These chains are ideal for felling trees and cutting clean, smooth lumber. However, they are also more prone to dulling in dirty or abrasive conditions.

Pros: Fast cutting, smooth finish
Cons: Dulls quickly in dirty conditions, requires more frequent sharpening
Best for: Clean wood, felling trees, milling lumber

Semi-Chisel Chains

Semi-chisel chains have rounded corners on their teeth, making them more durable and forgiving than full chisel chains. They can handle dirtier conditions without dulling as quickly. While they may not cut as fast as full chisel chains, they are a good all-around option for a variety of tasks.

Pros: Durable, versatile, good for dirty conditions
Cons: Not as fast as full chisel chains
Best for: General use, cutting firewood, working in dirty environments

Low-Profile Chains

Low-profile chains, also known as micro-chisel chains, have a smaller cutter design and a shallower cutting angle. This makes them less aggressive but also reduces the risk of kickback. These chains are often recommended for beginners or those who prioritize safety.

Pros: Reduced kickback, safer for beginners
Cons: Slower cutting speed
Best for: Homeowners, beginners, pruning

Tip #1: Selecting the Right Chain for Your Needs

Choosing the right chain for your Stihl Farm Boss is crucial for optimal performance and safety. Consider the type of wood you’ll be cutting, the conditions you’ll be working in, and your skill level.

Matching Chain Type to Wood Type

Different types of wood require different types of chains. For example, hardwoods like oak and maple are denser and more abrasive than softwoods like pine and fir.

Hardwoods: Semi-chisel or full chisel chains with carbide-tipped cutters are ideal for hardwoods. Carbide-tipped cutters are more resistant to wear and can hold their edge longer when cutting abrasive wood.
Softwoods: Full chisel chains are a good choice for softwoods, as they can cut quickly and efficiently through the softer fibers. However, semi-chisel chains can also be used for general-purpose cutting.

Considering Working Conditions

The conditions in which you’ll be using your chainsaw also play a role in chain selection. If you’ll be cutting in dirty or sandy environments, a semi-chisel chain is a better choice than a full chisel chain. The rounded corners of the semi-chisel teeth are less prone to dulling when exposed to abrasive materials.

Clean Conditions: Full chisel chains
Dirty Conditions: Semi-chisel chains

Matching Chain to Skill Level

If you’re a beginner or inexperienced chainsaw user, a low-profile chain is a good choice. These chains are designed to reduce the risk of kickback, which can be a major safety hazard. As you gain experience, you can move up to a more aggressive chain like a semi-chisel or full chisel.

Tip #2: Proper Chain Tensioning for Optimal Cutting

Maintaining the correct chain tension is essential for safe and efficient cutting. A chain that is too loose can derail, while a chain that is too tight can cause excessive wear on the bar and sprocket.

Checking Chain Tension

To check the chain tension, follow these steps:

Turn off the chainsaw: Always turn off the chainsaw and engage the chain brake before checking or adjusting the chain tension.
Wear gloves: Protect your hands by wearing gloves.
Lift the chain: Lift the chain away from the guide bar at the midpoint. The chain should lift about 1/8 inch (3 mm).
Rotate the chain: Rotate the chain around the guide bar by hand. It should move freely without binding.

Adjusting Chain Tension

If the chain tension is not correct, adjust it as follows:

Loosen the bar nuts: Use the wrench that came with your chainsaw to loosen the bar nuts that hold the guide bar in place.
Adjust the tensioning screw: Locate the tensioning screw on the side of the chainsaw. Turn the screw clockwise to tighten the chain and counterclockwise to loosen it.
Tighten the bar nuts: Once you have adjusted the chain tension to the correct level, tighten the bar nuts securely.
Recheck the tension: After tightening the bar nuts, recheck the chain tension to ensure that it is still correct.

Factors Affecting Chain Tension

Several factors can affect chain tension, including:

Temperature: The chain will expand as it heats up during use, so it’s important to check the tension periodically and adjust it as needed.
New chains: New chains tend to stretch during the first few hours of use, so check the tension frequently and adjust it as needed.
Guide bar wear: As the guide bar wears, the chain tension may need to be adjusted more frequently.

Tip #3: Sharpening Your Chain for Peak Performance

A sharp chain is essential for efficient cutting and safe operation. A dull chain will require more force to cut through wood, which can increase the risk of kickback and put unnecessary strain on your chainsaw.

Recognizing a Dull Chain

Here are some signs that your chainsaw chain needs sharpening:

Sawdust: A sharp chain produces long, thin shavings, while a dull chain produces fine sawdust.
Increased force: If you have to apply more force than usual to cut through wood, your chain is likely dull.
