Understanding the Husqvarna 450 Rancher Bar and Chain

The Husqvarna 450 Rancher is a popular, versatile chainsaw, and getting the right bar and chain is crucial for safe and efficient operation. Using the wrong size or type can damage the saw, reduce cutting performance, and even be dangerous.

Key Terms and Concepts

Before we dive into the specifics, let’s define some key terms:

Bar Length: The usable cutting length of the chainsaw bar, measured from the tip to where it enters the chainsaw body.
Chain Pitch: The distance between three consecutive rivets on the chain, divided by two. Common pitches are .325″, 3/8″, and .404″.
Chain Gauge: The thickness of the drive links that fit into the groove of the bar. Common gauges are .043″, .050″, .058″, and .063″.
Drive Links: The small teeth on the chain that fit into the bar groove and are pulled around by the chainsaw’s sprocket.
Sprocket: The toothed wheel that drives the chain around the bar.
Green Wood: Freshly cut wood with a high moisture content.
Seasoned Wood: Wood that has been dried to reduce its moisture content, making it lighter and easier to burn.
Kerf: The width of the cut made by the chainsaw chain.

The Importance of Matching Bar and Chain

Using the correct bar and chain combination is paramount. An incorrect match can lead to:

Premature wear and tear: Mismatched components can cause excessive friction and stress on the saw.
Reduced cutting performance: An incorrectly sized chain won’t engage properly with the sprocket, leading to inefficient cutting.
Safety hazards: An improperly fitted chain can derail, causing injury.

Husqvarna 450 Rancher Bar Size and Chain Specs: The Definitive Guide

Let’s get down to the specifics of the Husqvarna 450 Rancher.

1. Recommended Bar Length:

The Husqvarna 450 Rancher typically accepts bar lengths ranging from 13 inches to 20 inches. The most common and recommended bar length is 18 inches.

Why 18 inches is popular: It offers a good balance between maneuverability and cutting capacity, suitable for felling small to medium-sized trees, limbing, and cutting firewood.
My Experience: I’ve used the 18-inch bar on my 450 Rancher for years. I find it ideal for tackling most tasks around my property, from clearing fallen branches after a storm to cutting firewood logs up to 16 inches in diameter.
Considerations for Bar Length:
- Tree size: If you’re primarily felling larger trees (over 24 inches in diameter), a longer bar (20 inches) might be beneficial.
- Maneuverability: A shorter bar (13-16 inches) is easier to handle in tight spaces and for limbing.
- User experience: If you’re new to chainsaws, starting with a shorter bar can make the saw feel less intimidating.

2. Chain Pitch:

The Husqvarna 450 Rancher uses a .325″ pitch chain.

What .325″ Pitch Means: This refers to the spacing between the chain’s rivets. It’s a common pitch for mid-sized chainsaws, offering a good balance between cutting speed and durability.
Why This Pitch? The .325″ pitch is well-suited for the 450 Rancher’s engine power and cutting applications.

3. Chain Gauge:

The Husqvarna 450 Rancher typically uses a .050″ gauge chain.

What .050″ Gauge Means: This refers to the thickness of the drive links. It needs to match the width of the groove on the chainsaw bar.
The Importance of Matching Gauge: Using the wrong gauge will prevent the chain from fitting properly in the bar groove. A chain that’s too thick won’t fit, and a chain that’s too thin will wobble and potentially derail.

4. Drive Link Count:

The number of drive links depends on the bar length. Here’s a breakdown:

13-inch bar: Approximately 56 drive links
16-inch bar: Approximately 66 drive links
18-inch bar: Approximately 72 drive links
20-inch bar: Approximately 78 drive links
How to Determine the Correct Drive Link Count: The easiest way is to count the drive links on your existing chain. If you don’t have an old chain, consult the chainsaw’s manual or the bar manufacturer’s specifications.
My Tip: Always double-check the drive link count before purchasing a new chain. A chain with the wrong number of drive links will not fit properly on the bar.

5. Chain Type/Style:

There are different types of chains available, each designed for specific cutting applications. Common types include:

Full Chisel: Aggressive cutting, fast but requires more skill to sharpen. Best for clean wood.
Semi-Chisel: More forgiving than full chisel, good for general-purpose cutting.
Low-Kickback (Safety Chain): Designed to reduce the risk of kickback, ideal for beginners.
Micro-Lite: Narrow kerf for faster cutting with smaller saws.
My Recommendation: For the Husqvarna 450 Rancher, a semi-chisel chain is a good all-around choice. It provides a good balance of cutting speed, durability, and ease of sharpening. If you’re a beginner, a low-kickback chain is a safer option.

Maintaining Your Bar and Chain: Extending Their Lifespan

Proper maintenance is essential for maximizing the life of your bar and chain.

Chain Sharpening:

Why Sharpening is Crucial: A sharp chain cuts faster, requires less effort, and reduces stress on the saw.
When to Sharpen: Sharpen your chain every time you refuel, or whenever you notice the cutting performance declining.
How to Sharpen: Use a chainsaw file kit with the correct file size and angle. Follow the manufacturer’s instructions.
My Tip: Invest in a good quality chainsaw file kit and learn how to sharpen your chain properly. It will save you money in the long run and improve your cutting efficiency. I personally use a Stihl file kit and find it to be excellent.
Alternatively: Consider using a chainsaw chain grinder for faster and more precise sharpening if you have to sharpen chains frequently.

Bar Maintenance:

Cleaning: Regularly clean the bar groove with a bar groove cleaner or a small screwdriver to remove sawdust and debris.
Lubrication: Ensure the bar is properly lubricated. Check the oil level frequently and use a good quality bar and chain oil.
Flipping the Bar: Regularly flip the bar to ensure even wear.
Checking for Wear: Inspect the bar for wear and damage. Replace the bar if it’s bent, cracked, or excessively worn.
My Experience: I’ve extended the life of my chainsaw bars by regularly cleaning and lubricating them. I also flip the bar every few uses to ensure even wear.

Chain Tension:

Why Proper Tension is Important: Too loose, and the chain can derail. Too tight, and it can cause excessive wear on the bar and chain.
How to Adjust Tension: Follow the instructions in your chainsaw’s manual.
Checking Tension: The chain should be snug against the bar but still able to be pulled around by hand.
My Tip: Check the chain tension frequently, especially when the chain is new. New chains tend to stretch initially.

Drying Firewood: A Critical Step

Drying or “seasoning” firewood is essential for efficient burning and reducing creosote buildup in your chimney.

The Process:

Split the wood: Splitting the wood increases the surface area exposed to air, accelerating the drying process.
Stack the wood: Stack the wood in a single row, off the ground, with good air circulation.
Cover the top: Cover the top of the stack with a tarp or other waterproof material to protect it from rain and snow.
Allow to dry: Allow the wood to dry for 6-12 months, depending on the type of wood and the climate.
Check moisture content: Use a moisture meter to check the moisture content of the wood before burning.

Stacking Techniques:

The Traditional Row: Simple and effective, allows for good air circulation.
The Holzhaufen: A circular stack that is aesthetically pleasing and provides good stability.
The Pallet Stack: Using pallets to elevate the wood off the ground improves air circulation.

My Firewood Stacking Method:

I use a combination of the traditional row and the pallet stack. I stack the wood in single rows on top of pallets, leaving space between the rows for air circulation. I cover the top of the stack with a tarp to protect it from the rain. I also elevate the stacks to ensure good air flow underneath, which helps with drying. This method has proven to be very effective in drying firewood quickly and efficiently.
