Choosing the Right Bar and Chain for Your Rancher 55

Selecting the right bar and chain is the foundation for efficient and safe operation. The Rancher 55 is a versatile saw, but matching the cutting equipment to the task is crucial.

Understanding Bar Length

The Husqvarna Rancher 55 can typically accommodate bar lengths from 13 inches to 20 inches. The ideal length depends on the size of the trees you’ll be felling or the diameter of the wood you’ll be cutting for firewood.

Shorter Bars (13-16 inches): These are great for limbing, pruning, and cutting smaller firewood. They offer better maneuverability and are lighter to handle, reducing fatigue during extended use.
Medium Bars (18 inches): This is a good all-around choice for general firewood cutting and felling small to medium-sized trees (up to around 16 inches in diameter). I find this length offers a good balance between power and control.
Longer Bars (20 inches): These are best suited for felling larger trees (up to around 18 inches in diameter). However, they require more power from the saw and can be more challenging to control, especially for inexperienced users.

My Experience: I primarily use an 18-inch bar on my Rancher 55. It’s perfect for handling the majority of firewood I process, which typically consists of oak and maple logs ranging from 6 to 14 inches in diameter.

Chain Types: Which One is Right for You?

Chains come in various configurations, each designed for specific cutting applications.

Full Chisel Chains: These have aggressive, square-cornered cutters that slice through wood quickly. They are ideal for experienced users cutting clean, softwoods. However, they dull more easily and are more susceptible to damage from dirt or debris.
Semi-Chisel Chains: These have rounded cutters that are more forgiving and durable than full chisel chains. They are a good all-around choice for cutting both hardwoods and softwoods, and they are more resistant to dulling from dirt. I generally recommend these for most users.
Low-Profile Chains (also known as Micro-Chisel): These have smaller cutters and a lower kickback risk. They are a good choice for beginners or those concerned about safety. However, they cut slower than full or semi-chisel chains.

Pro Tip: Consider the pitch and gauge of the chain. The Rancher 55 typically uses a .325″ pitch chain with a .050″ gauge. Always ensure you are using the correct specifications for your saw.

Understanding Chain Pitch and Gauge

Chain pitch and gauge are crucial measurements that determine compatibility with your chainsaw’s bar and drive sprocket.

Pitch: This refers to the distance between three consecutive rivets on the chain, divided by two. It’s usually expressed in inches (e.g., .325″, 3/8″).
Gauge: This refers to the thickness of the drive links that fit into the groove of the guide bar. It’s also usually expressed in inches (e.g., .050″, .058″).

Why It Matters: Using the wrong pitch or gauge chain can damage your saw and create a safety hazard. Always consult your owner’s manual or the specifications stamped on your guide bar to determine the correct chain for your Rancher 55.

Real-World Example: I once tried to use a chain with the wrong pitch on my Rancher 55. The chain wouldn’t seat properly on the drive sprocket, and the saw vibrated excessively. I quickly realized my mistake and switched to the correct chain.

Takeaway: Always double-check the pitch and gauge of your chain before installing it on your Rancher 55.

Pro Tip #1: Chain Sharpening is Key

A sharp chain is not only more efficient but also safer. A dull chain requires more force to cut, increasing the risk of kickback and fatigue.

The Importance of a Sharp Chain

A sharp chain bites into the wood cleanly, producing consistent chips. A dull chain, on the other hand, tears at the wood, producing sawdust and requiring more pressure to cut.

Benefits of a Sharp Chain:

Increased Cutting Speed: A sharp chain cuts through wood much faster, saving you time and effort.
Reduced Fatigue: A sharp chain requires less force to operate, reducing strain on your body.
Improved Safety: A sharp chain is less likely to kick back, reducing the risk of injury.
Prolonged Saw Life: A sharp chain reduces stress on the saw’s engine and components, extending its lifespan.

Sharpening Tools and Techniques

There are several ways to sharpen a chainsaw chain:

Round File and Guide: This is the most common and affordable method. A round file is used to sharpen each cutter individually, while a guide helps maintain the correct angle and depth. I prefer this method for field sharpening.
Electric Chain Sharpener: This is a faster and more precise method, but it requires a power source and is less portable.
Bench Grinder: Similar to an electric chain sharpener, a bench grinder offers precision but is not portable.

My Method: I use a round file and guide for most of my sharpening. I find it allows me to maintain the chain’s sharpness in the field without having to stop and set up an electric sharpener.

Sharpening Steps:

Secure the Chain: Use a vise or log to hold the chain securely.
Identify the Correct File Size: Match the file size to the chain’s pitch (e.g., a 5/32″ file for a .325″ pitch chain).
Use a Filing Guide: Place the guide on the chain, aligning it with the cutter.
File at the Correct Angle: Maintain the correct filing angle (typically 25-35 degrees).
File Each Cutter Evenly: Make several consistent strokes on each cutter, ensuring they are all sharpened to the same length.
Lower the Depth Gauges: Use a flat file and depth gauge tool to lower the depth gauges (rakers) to the correct height (typically .025″-.030″).

Expert Advice: Sharpen your chain frequently, ideally after every few tanks of gas. A slightly dull chain is much easier to sharpen than a severely dull chain.

Takeaway: Regular chain sharpening is essential for safe and efficient chainsaw operation.

Pro Tip #2: Mastering Chain Tension

Proper chain tension is crucial for optimal cutting performance and preventing premature wear.

Why Chain Tension Matters

If the chain is too loose, it can derail from the bar, causing damage and posing a safety hazard. If the chain is too tight, it can bind and overheat, leading to excessive wear on the bar, chain, and sprocket.

Symptoms of Incorrect Chain Tension:

Chain is Too Loose: The chain sags noticeably below the bar. It may also derail easily.
Chain is Too Tight: The chain is difficult to pull around the bar by hand. The bar may also become hot to the touch.

Adjusting Chain Tension

The Rancher 55 typically has a side-mounted chain tensioner.

Steps to Adjust Chain Tension:

Loosen the Bar Nuts: Use a wrench to loosen the bar nuts that secure the bar to the saw.
Adjust the Tensioner: Use a screwdriver to turn the chain tensioner screw. Turning the screw clockwise tightens the chain, while turning it counterclockwise loosens the chain.
Check the Tension: The chain should be snug against the bar, but you should still be able to pull it around the bar by hand. When you pull the chain down slightly from the middle of the bar, the drive links should remain in the bar groove.
Tighten the Bar Nuts: Once you have achieved the correct tension, tighten the bar nuts securely.

My Experience: I check my chain tension frequently, especially when using a new chain. A new chain will stretch slightly during the first few uses, requiring adjustments.

Pro Tip: Adjust chain tension with the saw turned off and the bar cool. A hot bar will expand, making the chain appear tighter than it actually is.

Takeaway: Regularly check and adjust your chain tension to ensure optimal performance and prevent damage.

Pro Tip #3: Oiling is Essential

Proper lubrication is vital for the longevity of your bar and chain.

The Role of Bar and Chain Oil

Bar and chain oil reduces friction between the chain, bar, and sprocket. This prevents overheating, reduces wear, and helps the chain cut smoothly.

Consequences of Insufficient Lubrication:

Premature Wear: Lack of lubrication can cause the bar and chain to wear out quickly.
Overheating: Friction can generate excessive heat, damaging the bar and chain.
Reduced Cutting Performance: A dry chain cuts less efficiently and requires more force to operate.

Choosing the Right Oil

Use a high-quality bar and chain oil specifically designed for chainsaws. Avoid using motor oil or other substitutes, as they may not provide adequate lubrication and can damage the saw.

Oil Types:

Petroleum-Based Oils: These are the most common type of bar and chain oil.
Vegetable-Based Oils: These are biodegradable and environmentally friendly.
Synthetic Oils: These offer superior lubrication and performance, especially in extreme temperatures.

My Choice: I prefer to use a high-quality petroleum-based bar and chain oil for my Rancher 55. I find it provides excellent lubrication and protection at a reasonable price.

Checking and Maintaining Oil Levels

Always check the oil level before each use. The Rancher 55 has an oil tank with a sight window, allowing you to easily monitor the oil level.

Oil Consumption:

The amount of oil your saw consumes will vary depending on the type of wood you are cutting and the operating conditions. As a general rule, you should use approximately one tank of oil for every tank of fuel.

Pro Tip: If you notice that your chain is smoking or the bar is becoming hot, stop cutting immediately and check the oil level.

Takeaway: Consistent and proper lubrication is crucial for extending the life of your bar and chain.
