18 Inch Bar And Chain For Husqvarna: Top Picks (Pro Guide)

Imagine you’re standing at the edge of a woodlot, the scent of pine and damp earth filling your lungs. A downed oak, thick as a small car, lies before you. Your mission? To transform this behemoth into manageable firewood, ready to warm homes through the coming winter. But you’re not alone; in your hands, you hold a Husqvarna chainsaw, a tool known for its reliability and power. The key to unlocking its potential, however, lies in the heart of the machine: the bar and chain. Specifically, we’re talking about the ubiquitous 18-inch bar and chain, a size that strikes a balance between maneuverability and cutting capacity, making it a favorite among homeowners and professionals alike.

I’ve spent years felling trees, bucking logs, and splitting firewood, and I’ve learned firsthand the importance of a well-matched bar and chain. I’ve seen chains dull prematurely, bars wear unevenly, and even experienced kickback incidents due to improper selection. This guide is born from those experiences, combined with in-depth research and a passion for sharing knowledge. Let’s dive in!

Understanding the Anatomy of a Chainsaw Bar and Chain

Before we delve into specific recommendations, let’s break down the components of a chainsaw bar and chain. Understanding these elements is crucial for making informed decisions.

Chainsaw Bar Components

Bar Length: The usable cutting length of the bar, measured from the tip to where it enters the powerhead. An 18-inch bar is ideal for felling trees up to approximately 36 inches in diameter (though I generally recommend not exceeding 1.5 times the bar length for safe felling) and bucking larger logs.
Bar Mount: The portion of the bar that attaches to the chainsaw. Husqvarna chainsaws typically use a standard mount, but it’s crucial to verify compatibility with your specific model.
Bar Gauge: The width of the drive links (the part of the chain that sits in the bar groove) that fit into the bar groove. Common gauges are .050″, .058″, and .063″. Using the wrong gauge can lead to chain slippage or binding.
Bar Nose: The tip of the bar, which can be either sprocket-nosed (with a roller bearing for reduced friction) or solid-nosed. Sprocket-nosed bars are generally preferred for their smoother cutting action and reduced wear on the chain.

Chainsaw Chain Components

Cutters: The teeth that do the actual cutting. Cutters come in various designs, including chisel, semi-chisel, and chipper.
- Chisel Cutters: These have square corners and are the sharpest, fastest-cutting type. However, they dull quickly and are best suited for clean wood.
- Semi-Chisel Cutters: These have rounded corners, making them more durable and forgiving in dirty or knotty wood. They’re a good all-around choice.
- Chipper Cutters: These have rounded corners and a larger cutting surface, making them the most durable but also the slowest-cutting.
Drive Links: The part of the chain that sits in the bar groove and is driven by the chainsaw’s sprocket. The number of drive links is specific to the bar length and chainsaw model.
Tie Straps: Connect the cutters and drive links.
Depth Gauges (Rakers): Located in front of each cutter, these control the depth of the cut. Proper depth gauge filing is crucial for efficient cutting and preventing kickback.

Key Chain Specifications

Chain Pitch: The distance between three consecutive rivets divided by two. Common pitches are .325″, 3/8″, and .404″. The pitch must match the chainsaw’s sprocket.
Number of Drive Links: A critical specification that must match the bar length and chainsaw model. Using the wrong number of drive links will prevent the chain from fitting properly.
Chain Gauge: As mentioned earlier, the width of the drive links.

Husqvarna Chainsaw Compatibility

Not all 18-inch bars and chains are created equal. Before purchasing, you must ensure compatibility with your specific Husqvarna chainsaw model. Here’s a general guideline, but always consult your chainsaw’s owner’s manual for the most accurate information:

Husqvarna 455 Rancher: Typically uses an 18-inch bar with a .325″ pitch, .050″ gauge, and 72 drive links.
Husqvarna 460 Rancher: Similar to the 455 Rancher, often uses an 18-inch bar with a .325″ pitch, .050″ gauge, and 72 drive links.
Husqvarna 450: Can use an 18-inch bar with a .325″ pitch, .050″ gauge, and 72 drive links.
Husqvarna 142: A smaller saw that may be better suited with a 16-inch bar, but can use an 18-inch bar with a .325″ pitch, .050″ gauge, and 72 drive links.

Personal Story: I once tried to fit a chain with the wrong number of drive links on my Husqvarna 455 Rancher. I spent a frustrating hour trying to force it on before realizing my mistake. Always double-check the specifications!

Advanced Wood Processing Techniques

Now that we’ve covered the basics of bar and chain selection and maintenance, let’s delve into some advanced wood processing techniques that can help you maximize your efficiency and safety.

Felling Techniques

Planning the Fell: Before felling a tree, assess its lean, wind direction, and potential hazards. Plan a clear escape route.
The Notch: Cut a notch on the side of the tree in the direction you want it to fall. The notch should be about 1/3 of the tree’s diameter.
The Back Cut: Make a back cut on the opposite side of the tree, slightly above the notch. Leave a hinge of wood to control the fall.
The Push: Use a felling lever or wedge to help push the tree over in the desired direction.
Personal Story: I once misjudged the lean of a tree and it fell in the wrong direction, narrowly missing my truck. Always take the time to properly assess the situation!

Bucking Techniques

Supporting the Log: When bucking a log, support it to prevent pinching the bar. Use wedges or other logs to create a stable cutting surface.
Cutting from Above: Cut from above, stopping before you reach the bottom of the log.
Cutting from Below: Finish the cut from below, being careful to avoid pinching the bar.
Step Cutting: For larger logs, use a step cutting technique to remove sections of wood gradually.

Splitting Techniques

Manual Splitting: Use a splitting maul or axe to split logs by hand. Choose a sturdy chopping block and maintain a safe distance from others.
