Stihl FS 55 R: Best Budget Trimmer For Firewood Prep (3 Pro Tips)

It’s estimated that over 25 million households in the United States alone rely on firewood as a primary or secondary heating source. Getting that firewood ready, however, can be a real chore, especially if you’re dealing with a tight budget. That’s where the Stihl FS 55 R trimmer comes in. While it might seem unconventional, this little workhorse can be surprisingly effective for certain firewood prep tasks. In this article, I’ll share my personal experiences and expert tips on how to leverage this budget-friendly tool for your firewood needs.

The Stihl FS 55 R: An Unlikely Firewood Ally

Let’s be honest: when you think of firewood preparation, you probably picture burly guys wielding axes, hydraulic splitters roaring to life, or maybe even a chainsaw biting through thick logs. A string trimmer? Not so much. But hear me out. The Stihl FS 55 R, while primarily designed for lawn edging and trimming, can be a valuable asset in specific firewood-related scenarios, particularly for smaller tasks and cleanup.

Why Consider a Trimmer for Firewood?

The key here is understanding the limitations and strengths of the tool. The FS 55 R isn’t going to split massive oak rounds. However, it shines in the following areas:

Clearing Brush and Saplings: Before you even think about splitting logs, you need to clear the area. The FS 55 R is excellent for cutting down small brush, weeds, and saplings that clutter your woodlot or storage area. This creates a safer and more efficient workspace.
Preparing Kindling: Small twigs and branches are essential for starting fires. Instead of tediously snapping them by hand, the FS 55 R can quickly chop them into manageable sizes.
Cleaning Up Around the Woodpile: Keeping your woodpile area free of debris helps prevent insect infestations and promotes better airflow for drying. The FS 55 R can easily trim grass and weeds around the base of the pile.
Light-Duty Cutting of Small Branches: If you have very thin, green branches that need to be reduced in size, the FS 55 R can handle them with ease.

My Personal Experience: From Lawn Care to Firewood Prep

I initially bought my Stihl FS 55 R for basic lawn maintenance. Living on a small acreage, I needed something reliable for edging and trimming around fences and flower beds. It wasn’t until I started seriously focusing on firewood production that I realized its potential beyond the lawn.

One particular year, I had a massive amount of buckthorn invading my property. Buckthorn is an invasive species that can quickly take over a woodlot. I needed to clear it out, but the chainsaw felt like overkill for the smaller plants. That’s when I reached for the FS 55 R. It was surprisingly effective at cutting down the smaller buckthorn stems, allowing me to clear a large area quickly and efficiently. This experience opened my eyes to the versatility of this tool.

Pro Tip #1: Mastering the Trimmer Head for Firewood Tasks

The key to effectively using the FS 55 R for firewood-related tasks lies in understanding and mastering the trimmer head. The standard head that comes with the trimmer is designed for cutting grass, but with a few adjustments and techniques, you can significantly improve its performance on tougher vegetation.

Understanding Trimmer Head Types

While the FS 55 R typically comes with a standard bump-feed head, there are other options available that can enhance its cutting power:

Bump-Feed Head: This is the most common type. You tap the head on the ground to release more line. It’s suitable for grass and light weeds but can struggle with thicker vegetation.
Fixed-Line Head: These heads use pre-cut lengths of trimmer line that are inserted into the head. They are generally more durable and can handle thicker vegetation than bump-feed heads.
Bladed Head: These heads replace the trimmer line with a small blade, typically made of plastic or metal. They are designed for cutting thicker weeds and brush, but they can be more dangerous if not used properly.

Choosing the Right Trimmer Line

The type of trimmer line you use also significantly impacts performance. Here’s a breakdown of common line types:

Round Line: This is the most common type, suitable for general trimming.
Square Line: This line has sharp edges that provide a more aggressive cut, making it better for thicker vegetation.
Twisted Line: This line is designed to be more durable and resistant to breaking.
Serrated Line: This line has a saw-like edge that provides the most aggressive cut, ideal for tough weeds and brush.

For firewood-related tasks, I recommend using a square or twisted line for increased cutting power and durability. I’ve found that a .095-inch diameter line works well in the FS 55 R for most brush-clearing applications.

Technique is Key: The “Sweep and Clear” Method

When clearing brush and saplings, don’t just hack away randomly. Use a controlled “sweep and clear” method:

Position Yourself: Stand with a stable stance, facing the vegetation you want to cut.
Angle the Trimmer Head: Angle the trimmer head slightly downward, so the line is cutting at a slight angle.
Sweep from Side to Side: Sweep the trimmer head from side to side, cutting through the vegetation as you move.
Overlap Your Cuts: Overlap your cuts slightly to ensure you’re not leaving any vegetation behind.
Maintain Consistent Speed: Maintain a consistent speed as you sweep, allowing the line to do the work.

Important Safety Note: Always wear safety glasses and hearing protection when operating a trimmer. Also, be aware of your surroundings and watch out for flying debris.

Pro Tip #2: Adapting the FS 55 R for Kindling Creation

One of the most tedious aspects of firewood preparation is creating kindling. Snapping small twigs and branches by hand can be time-consuming and hard on your hands. The Stihl FS 55 R can significantly speed up this process.

Building a Simple Kindling Jig

To make the process safer and more efficient, I recommend building a simple kindling jig. This jig will hold the branches in place while you cut them, preventing them from flying around and reducing the risk of injury.

Here’s how to build a basic kindling jig:

Materials: You’ll need a piece of scrap wood (approximately 2 feet long), a few screws, and a clamp.
Create a Channel: Cut a shallow channel down the center of the wood, wide enough to hold the branches you want to cut.
Attach a Stop Block: Attach a small block of wood at one end of the channel to act as a stop block. This will prevent the branches from sliding through the jig.
Secure the Jig: Clamp the jig to a stable surface, such as a workbench or sawhorse.

Cutting Kindling with the Jig

Place Branches in the Jig: Place a handful of small branches in the channel of the jig, pressing them against the stop block.
Position the Trimmer: Position the trimmer head above the branches, making sure the line is clear of the jig.
Make Controlled Cuts: Slowly lower the trimmer head and make controlled cuts through the branches.
Repeat: Repeat the process until you have a pile of kindling.

This method is much faster and safer than snapping branches by hand. It also produces more uniform pieces of kindling, which are easier to light.

Optimizing Line Speed and Angle

For kindling creation, it’s crucial to optimize the line speed and cutting angle. A higher line speed will provide a cleaner cut, while a slight downward angle will help prevent the branches from kicking back. Experiment with different speeds and angles to find what works best for you.

Pro Tip #3: Maintaining Your FS 55 R for Longevity

Like any power tool, the Stihl FS 55 R requires regular maintenance to ensure optimal performance and longevity. Neglecting maintenance can lead to decreased cutting power, increased fuel consumption, and ultimately, a shorter lifespan for the tool.

Essential Maintenance Tasks

Here are some essential maintenance tasks you should perform regularly:

Clean the Air Filter: A dirty air filter restricts airflow to the engine, reducing power and increasing fuel consumption. Clean the air filter every 25 hours of use, or more frequently if you’re working in dusty conditions.
Check the Spark Plug: A fouled spark plug can cause starting problems and poor performance. Check the spark plug every 100 hours of use and replace it if necessary.
Inspect the Fuel Filter: A clogged fuel filter can restrict fuel flow to the engine, causing it to run poorly or stall. Inspect the fuel filter every 100 hours of use and replace it if necessary.
Grease the Gearhead: The gearhead transfers power from the engine to the trimmer head. Greasing the gearhead regularly will help prevent wear and tear.
Sharpen the Trimmer Line: A dull trimmer line will tear the vegetation instead of cutting it cleanly. Sharpen the trimmer line regularly using a file or a trimmer line sharpener.
Clean the Engine Housing: Keeping the engine housing clean will help prevent overheating and extend the life of the engine.
Store Properly: Store the trimmer in a dry, sheltered location when not in use. Drain the fuel tank before storing the trimmer for extended periods.

Fuel and Oil Considerations

The FS 55 R uses a two-stroke engine, which requires a mixture of gasoline and oil. Using the correct fuel and oil mixture is crucial for engine health.

Fuel: Use high-quality gasoline with an octane rating of 89 or higher.
Oil: Use a two-stroke oil specifically designed for air-cooled engines. I recommend using Stihl’s own two-stroke oil for optimal performance and protection.
Mixing Ratio: The recommended fuel-to-oil mixing ratio for the FS 55 R is 50:1. This means you should mix 50 parts gasoline with 1 part oil.

Important Note: Always mix fuel and oil in a separate container. Never mix fuel and oil directly in the fuel tank of the trimmer.

Troubleshooting Common Issues

Even with regular maintenance, you may encounter some common issues with your FS 55 R. Here are some troubleshooting tips:

Engine Won’t Start: Check the fuel level, spark plug, and air filter. Make sure the choke is in the correct position.
Engine Runs Poorly: Check the fuel filter, air filter, and spark plug. Clean the carburetor if necessary.
Trimmer Line Breaks Frequently: Use a higher-quality trimmer line or reduce the cutting speed.
Trimmer Head Won’t Advance Line: Clean the trimmer head and make sure the line is properly wound.

Wood Science and Firewood Preparation: A Deeper Dive

While the Stihl FS 55 R might seem like a simple tool, understanding some basic wood science principles can significantly improve your firewood preparation process and overall efficiency.

Understanding Wood Anatomy

Wood is a complex material composed of several different types of cells. The arrangement and characteristics of these cells determine the wood’s strength, density, and burning properties.

Cellulose: This is the main structural component of wood, making up about 40-50% of its dry weight.
Lignin: This is a complex polymer that binds the cellulose fibers together, providing rigidity and strength.
Hemicellulose: This is another type of carbohydrate that is found in wood, making up about 20-30% of its dry weight.
Extractives: These are various organic compounds that are found in wood, such as resins, tannins, and oils. They can affect the wood’s color, odor, and resistance to decay.

Hardwood vs. Softwood: What’s the Difference?

The terms “hardwood” and “softwood” refer to the type of tree the wood comes from, not necessarily the actual hardness of the wood.

Hardwoods: These come from deciduous trees, which are trees that lose their leaves in the fall. Hardwoods are generally denser and burn longer than softwoods. Examples of hardwoods include oak, maple, ash, and birch.
Softwoods: These come from coniferous trees, which are trees that have needles and cones. Softwoods are generally less dense and burn faster than hardwoods. Examples of softwoods include pine, fir, spruce, and cedar.

Moisture Content: The Key to Efficient Burning

The moisture content of firewood is a critical factor that affects its burning efficiency. Green wood, which has a high moisture content, is difficult to light and produces a lot of smoke. Seasoned wood, which has a low moisture content, is easy to light and burns cleanly.

Green Wood: Typically has a moisture content of 50% or higher.
Seasoned Wood: Has a moisture content of 20% or less.

Why Seasoning Matters:

Easier to Light: Seasoned wood ignites much more easily than green wood.
Burns Hotter: Seasoned wood burns hotter and more efficiently, producing more heat with less wood.
Less Smoke: Seasoned wood produces significantly less smoke, reducing air pollution and creosote buildup in your chimney.
Prevents Decay: Seasoning helps prevent decay and insect infestations.

Seasoning Techniques: Maximizing Airflow

The key to seasoning firewood is to maximize airflow around the wood. Here are some effective seasoning techniques:

Stacking: Stack the wood in a single row, with each piece slightly separated from the others. This allows air to circulate freely around the wood.
Elevation: Elevate the wood off the ground using pallets or scrap wood. This prevents moisture from wicking up into the wood.
Sun Exposure: Stack the wood in a sunny location. Sunlight helps to dry out the wood more quickly.
Covering: Cover the top of the woodpile with a tarp or sheet of plywood to protect it from rain and snow. However, leave the sides open to allow for airflow.
End-Splitting: Splitting the wood before seasoning it will significantly reduce the drying time.

How Long to Season:

The amount of time it takes to season firewood depends on the type of wood, the climate, and the seasoning technique. Generally, hardwoods require at least six months to a year to season properly, while softwoods may only require three to six months.

Estimating Firewood Needs: BTU Ratings

To estimate your firewood needs, it’s helpful to understand the concept of British Thermal Units (BTUs). BTU is a measure of the amount of heat energy contained in a fuel. Different types of wood have different BTU ratings.

Here are some approximate BTU ratings for common types of firewood (per cord):

Oak: 24-30 million BTU
Maple: 20-25 million BTU
Ash: 20-24 million BTU
Birch: 20-24 million BTU
Pine: 15-20 million BTU
Spruce: 15-18 million BTU

To estimate your firewood needs, determine how many BTUs you need to heat your home for the winter. This will depend on the size of your home, the climate, and the efficiency of your wood-burning stove or fireplace. Once you know how many BTUs you need, you can use the BTU ratings of different types of wood to estimate how much firewood you’ll need.
