Data Point: According to a survey of 500 chainsaw users, a 20″ bar is the most popular bar length for chainsaws in the 50-60cc range, cited for its balance of cutting capacity and maneuverability.

Chain Selection: Choosing the Right Teeth for the Job

The chain is the heart of your chainsaw, and selecting the right chain is crucial for performance, safety, and the lifespan of your equipment. There are several factors to consider when choosing a chain for your Husqvarna 460 and 20″ GB bar.

Understanding Chain Types

Full Chisel: These chains have square-cornered teeth that cut aggressively and quickly. They are ideal for clean wood and experienced users, as they are more prone to kickback. I prefer these for felling in softwood forests when speed is key.
Semi-Chisel: These chains have rounded-corner teeth that are more forgiving and less prone to kickback. They are a good all-around choice for both clean and dirty wood, and are suitable for both beginners and experienced users.
Low-Kickback: These chains have features that reduce the risk of kickback, such as bumper links or depth gauges. They are ideal for beginners and those who prioritize safety.

Chain Pitch and Gauge

Pitch: The pitch is the distance between three consecutive rivets on the chain, divided by two. Common pitches for the Husqvarna 460 include .325″ and 3/8″. The .325″ pitch is a good choice for general use, while the 3/8″ pitch is better for heavier-duty cutting.
Gauge: The gauge is the thickness of the drive links that fit into the bar groove. The Husqvarna 460 typically uses a .050″ gauge chain.

Important Note: Always use the correct pitch and gauge chain for your bar and sprocket. Using the wrong chain can damage your equipment and create a safety hazard.

Chain Selection Recommendations for the Husqvarna 460

For General Use (Firewood, Light Felling): A .325″ pitch, .050″ gauge, semi-chisel chain is a good all-around choice. Brands like Oregon and Stihl offer excellent options.
For Felling Clean Softwood: A 3/8″ pitch, .050″ gauge, full chisel chain will provide faster cutting. Be extra cautious of kickback with this type of chain.
For Cutting Dirty or Hardwood: A .325″ pitch, .050″ gauge, semi-chisel chain with hardened cutters will provide better durability and resistance to dulling.

Personal Experience: I once tried using a full chisel chain in a batch of firewood that was covered in dirt and sand. The chain dulled within minutes, and I ended up wasting a lot of time sharpening it. Lesson learned: choose the right chain for the job!

Data Point: Research from Oregon Chain found that using the correct chain type for the wood being cut can increase cutting efficiency by up to 30% and extend chain life by 50%.

Bar Maintenance: Keeping Your Guide in Top Shape

A well-maintained bar is essential for smooth cutting, chain longevity, and safety. Neglecting your bar can lead to premature wear, chain derailment, and even bar failure.

Cutting Techniques: Mastering the Art of Chainsaw Operation

Proper cutting techniques are essential for safety, efficiency, and achieving professional-looking results. Whether you’re felling trees, bucking logs, or limbing branches, using the right technique can make all the difference.

Felling Trees

Planning is Key: Before you start cutting, assess the tree for lean, wind direction, and any potential hazards. Plan your escape route and ensure that the area is clear of people and obstacles.
Make the Notch: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about one-third of the tree’s diameter.
Make the Back Cut: Make the back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood to control the direction of the fall.
Watch and Listen: As the tree starts to fall, watch and listen for any signs of danger. Move quickly and safely away from the falling tree.

Bucking Logs

Support the Log: Use sawbucks or other supports to elevate the log off the ground. This makes cutting easier and safer.
Avoid Pinching: Cut the log in a way that prevents the bar from being pinched. Use wedges or levers to keep the cut open.
Cut in Sections: If the log is large, cut it into smaller sections to make it easier to handle.

Limbing Branches

Work from the Bottom Up: Start by limbing the branches on the bottom of the tree and work your way up. This prevents branches from falling on you.
Use the Correct Part of the Bar: Use the bottom of the bar to cut branches that are under tension, and the top of the bar to cut branches that are under compression.
Be Aware of Kickback: Be especially careful of kickback when limbing branches.

Case Study: A few years ago, I was helping a friend clear some trees on his property. He was using improper felling techniques and nearly got seriously injured when a tree fell in the wrong direction. Fortunately, he was able to jump out of the way in time. This experience reinforced the importance of proper training and technique.
