How Do I Fell a Tree Safely? (Pro Tips for Small Diameter Logs)

“How Do I Fell a Tree Safely? (Pro Tips for Small Diameter Logs)” User Intent:

The user wants to learn the safest and most effective methods for felling small diameter trees, likely for firewood or small-scale logging. They are looking for practical advice, step-by-step instructions, and safety precautions specific to handling smaller trees. The user is a DIYer, hobbyist, or small-scale logger who needs guidance on proper techniques, tool selection, and potential hazards involved in tree felling.

Okay, let’s talk about trees. I remember a time when my old golden retriever, Buddy, used to chase squirrels around this massive oak in my backyard. He’d bark and carry on, completely oblivious to the potential danger of a falling branch. That oak, though, was far too big for me to even consider felling myself.

Why Focus on Small Diameter Trees?

You might be thinking, “Big trees are the dangerous ones!” And, yes, they are. But small diameter trees (generally considered anything under 12 inches in diameter at breast height, or DBH) present their own unique set of challenges. They might be more prone to snapping unexpectedly, or they might have hidden weaknesses you can’t see. Plus, a lot of folks starting out in wood processing or firewood preparation tend to underestimate the risks involved with these smaller trees, leading to accidents.

I’ve seen it firsthand – a friend of mine tried to fell a small, leaning birch without properly planning his escape route. The tree kicked back, narrowly missing him. He was lucky.

This guide is for the weekend warrior, the homeowner clearing brush, and anyone who wants to learn the right way to safely and efficiently fell smaller trees. We’ll cover everything from assessing the tree and choosing the right tools to executing the felling cut and dealing with potential hazards. Let’s get started.

Understanding Your Target: Tree Anatomy and Properties

Before you even think about picking up a chainsaw, you need to know your enemy, or in this case, your woody friend. Understanding tree anatomy and wood properties is crucial for making informed decisions about felling.

The Basic Anatomy:

Think of a tree like a living, breathing building. It has a foundation (roots), a support structure (trunk), and a canopy (branches and leaves). Here’s a quick rundown:

• Roots: Anchor the tree and absorb water and nutrients.
• Trunk: Provides support and transports water and nutrients between the roots and the canopy.
• Bark: The outer protective layer of the trunk.
• Cambium: A thin layer of cells responsible for growth.
• Sapwood: The living, outer layer of wood that transports water and nutrients.
• Heartwood: The dead, inner layer of wood that provides structural support.

Wood Properties: Hardwood vs. Softwood

The terms “hardwood” and “softwood” don’t actually refer to the density of the wood; rather, they refer to the type of tree. Hardwoods come from deciduous trees (trees that lose their leaves annually), while softwoods come from coniferous trees (trees that typically have needles and cones).

• Hardwoods: Generally denser and more durable than softwoods, making them ideal for furniture, flooring, and high-heat firewood. Examples include oak, maple, birch, and ash.
• Softwoods: Lighter and easier to work with than hardwoods, making them suitable for construction, paper production, and kindling. Examples include pine, fir, spruce, and cedar.

Why Does This Matter When Felling?

Knowing the type of wood you’re dealing with can influence your felling strategy. Hardwoods, being denser, might require more powerful equipment and a more deliberate approach. Softwoods, while easier to cut, might be more prone to splintering or unexpected movement.

Moisture Content: The Hidden Variable

The moisture content of wood plays a huge role in its weight, strength, and how it behaves when you cut it. “Green” wood (freshly cut wood) can have a moisture content of over 100% (meaning it weighs more than its dry weight). Seasoned firewood, on the other hand, should have a moisture content of around 20%.

• Green Wood: Heavier, harder to cut, and more prone to binding your chainsaw.
• Seasoned Wood: Lighter, easier to cut, and less likely to bind.

I’ve found that cutting green wood can be a real pain, especially with smaller chainsaws. The wood fibers tend to grab and pinch the bar, making the cut much slower and more tiring. That’s why I always try to fell trees in the late fall or winter when the sap is down, and the moisture content is naturally lower.

Data Point: A study by the USDA Forest Service found that the moisture content of freshly cut oak can be as high as 80%, while air-dried oak typically has a moisture content of 15-20%.

Actionable Tip: Before you start felling, take a look at the tree’s leaves (if it has any). Are they vibrant and full, indicating high sap flow? Or are they starting to turn brown and dry out? This can give you a clue about the tree’s moisture content.

Arming Yourself: Logging Tool Selection and Maintenance

Choosing the right tools and keeping them in top condition is essential for safe and efficient tree felling. We’re not just talking about chainsaws here; a whole arsenal of equipment can make the job easier and safer.

The Chainsaw: Your Primary Weapon

The chainsaw is the star of the show, but not all chainsaws are created equal. For small diameter trees, a smaller, lighter chainsaw is often the best choice.

• Gas vs. Electric: Gas chainsaws offer more power and portability, while electric chainsaws are quieter, lighter, and require less maintenance. For occasional use and smaller trees, an electric chainsaw might be sufficient. However, for more demanding tasks, a gas-powered saw is the way to go.
• Bar Length: A longer bar allows you to cut thicker trees, but it also makes the saw heavier and more difficult to maneuver. For small diameter trees, a bar length of 14-16 inches is usually sufficient.
• Engine Size: A larger engine provides more power, but it also increases the weight of the saw. For small diameter trees, an engine size of 30-40cc is typically adequate.

My Recommendation: For small diameter trees, I personally prefer a gas-powered chainsaw with a 16-inch bar and an engine size of around 35cc. It strikes a good balance between power, maneuverability, and weight. Stihl and Husqvarna are two brands that consistently deliver quality and reliability.

Beyond the Chainsaw: Essential Support Tools

• Personal Protective Equipment (PPE): This is non-negotiable. Always wear a helmet, safety glasses, hearing protection, gloves, chainsaw chaps, and sturdy boots.
• Felling Axe or Wedge: Used to help direct the fall of the tree and prevent the saw from binding.
• Sledgehammer: Used to drive the felling wedge.
• Measuring Tape: Used to measure the diameter of the tree and plan your cuts.
• Marking Paint or Flagging Tape: Used to mark your felling direction and potential hazards.
• First-Aid Kit: Accidents happen. Be prepared.
• Winch or Come-Along: For pulling trees that are leaning in the wrong direction.
• Peavey or Cant Hook: For rolling and positioning logs.

Maintenance: Keeping Your Tools Sharp and Ready

A dull chainsaw is a dangerous chainsaw. A sharp chain cuts more efficiently, reduces kickback, and puts less strain on the engine.

• Chain Sharpening: Learn how to sharpen your chainsaw chain properly using a file or a chain grinder. I recommend sharpening your chain every time you refuel.
• Bar Maintenance: Clean the bar regularly and check for wear and tear. Replace the bar if it’s damaged or worn.
• Air Filter: Clean or replace the air filter regularly to ensure proper engine performance.
• Spark Plug: Replace the spark plug annually or as needed.
• Fuel and Oil: Use the correct fuel and oil mixture for your chainsaw.
• Regular Inspections: Before each use, inspect your chainsaw for any signs of damage or wear.

Data Point: Studies have shown that a sharp chainsaw can reduce cutting time by up to 50% and significantly decrease the risk of kickback.

Actionable Tip: Invest in a good quality chainsaw sharpening kit and learn how to use it properly. There are plenty of online tutorials and videos that can guide you through the process.

The Art of the Cut: Felling Techniques for Small Diameter Logs

Now for the main event: the actual felling process. This is where your planning and preparation come together.

Step 1: Assessing the Tree and the Surroundings

Before you make a single cut, take a good look at the tree and its surroundings.

• Lean: Is the tree leaning in a particular direction? This will influence its natural fall.
• Branches: Are there any heavy branches that could cause the tree to fall unexpectedly?
• Wind: What is the direction and strength of the wind? Wind can significantly affect the fall of the tree.
• Obstacles: Are there any buildings, power lines, fences, or other obstacles in the tree’s path?
• Escape Route: Plan your escape route before you start cutting. You should have a clear path away from the tree at a 45-degree angle to the direction of the fall.

Step 2: The Notch Cut (The Key to Control)

The notch cut is the most important cut you’ll make. It determines the direction of the fall.

• Open-Faced Notch: This is the most common type of notch cut. It consists of two cuts: a top cut at a 45-degree angle and a horizontal bottom cut that meets the top cut. The notch should be about 1/3 of the tree’s diameter.
• Humboldt Notch: This notch is similar to the open-faced notch, but the top cut is horizontal, and the bottom cut is at a 45-degree angle. It’s often used for trees with a significant lean.

Step 3: The Back Cut (The Trigger)

The back cut is made on the opposite side of the tree from the notch cut. It’s what actually causes the tree to fall.

• Leave a Hinge: Never cut completely through the tree. Leave a hinge of wood (about 1/10 of the tree’s diameter) between the back cut and the notch cut. This hinge will help control the fall of the tree.
• Level Cut: Make the back cut level with the bottom of the notch cut.
• Wedge Placement: If you’re using a felling wedge, insert it into the back cut before you finish the cut. This will help prevent the tree from pinching the saw and ensure a clean fall.

Step 4: The Fall (The Moment of Truth)

Once you’ve made the notch cut and the back cut, it’s time to step back and let gravity do its thing.

• Shout “Timber!”: Give a warning shout to alert anyone nearby that the tree is about to fall.
• Retreat Quickly: Move away from the tree along your planned escape route.
• Watch the Fall: Keep an eye on the tree as it falls to make sure it’s going in the intended direction.

Dealing with Leaners: When Gravity Isn’t Your Friend

Leaning trees can be tricky and dangerous. Here are a few tips for dealing with them:

• Use a Winch or Come-Along: If the tree is leaning in the wrong direction, use a winch or come-along to pull it in the desired direction before you make the back cut.
• Back Cut First: In some cases, you can make the back cut first, leaving a thick hinge, and then carefully cut the notch cut to release the tree. This requires experience and careful judgment.
• Call a Professional: If you’re not comfortable felling a leaning tree, don’t hesitate to call a professional arborist.

Stuck Saw? Don’t Panic!

It happens to the best of us. Your saw gets pinched in the cut. Here’s what to do:

• Don’t Force It: Trying to force the saw out can damage the saw and potentially cause an accident.
• Use a Wedge: Insert a felling wedge into the cut to relieve the pressure on the saw.
• Use a Second Saw: If you have a second chainsaw, you can use it to cut the tree from the opposite side of the pinch.
• Call for Help: If you can’t free the saw, don’t hesitate to call for help.

Data Point: According to the Tree Care Industry Association (TCIA), improper felling techniques are a leading cause of chainsaw-related injuries.

Actionable Tip: Practice your felling techniques on smaller, less challenging trees before tackling larger or more complicated trees. Start small and work your way up.

From Forest to Fireplace: Firewood Seasoning and Safety

Once you’ve felled the tree, the work isn’t over. You still need to process the wood into firewood and season it properly.

Cutting and Splitting: Making Firewood-Sized Pieces

• Bucking: Cutting the felled tree into manageable lengths. I usually cut my firewood into 16-inch lengths, which fit nicely in my wood stove.
• Splitting: Splitting the logs into smaller pieces. This helps them dry faster and makes them easier to burn.

Manual vs. Hydraulic Splitters: Choosing Your Weapon

• Manual Splitters: Simple, inexpensive, and require no fuel or electricity. However, they can be tiring to use for large quantities of wood.
• Hydraulic Splitters: More expensive and require fuel or electricity, but they can split wood much faster and with less effort.

My Recommendation: If you’re only processing a small amount of firewood each year, a manual splitter might be sufficient. But if you’re processing a lot of wood, a hydraulic splitter is a worthwhile investment. I’ve used both, and I can tell you, after a long day of splitting wood, that hydraulic splitter feels like a gift from the gods.

Seasoning: The Key to Efficient Burning

Seasoning firewood is the process of drying the wood to reduce its moisture content. Properly seasoned firewood burns hotter, cleaner, and produces less smoke.

• Stacking: Stack the firewood in a single row, off the ground, with plenty of air circulation. I use pallets to keep the wood off the ground.
• Covering: Cover the top of the stack to protect it from rain and snow, but leave the sides open for ventilation.
• Time: Allow the firewood to season for at least six months, preferably a year or more.

Data Point: A study by the University of Maine found that properly seasoned firewood can produce up to 50% more heat than green firewood.

Actionable Tip: Invest in a moisture meter to check the moisture content of your firewood. Firewood is properly seasoned when the moisture content is below 20%.

Safety Considerations:

• Wear PPE: Always wear safety glasses, gloves, and sturdy boots when cutting and splitting firewood.
• Clear the Area: Keep the work area clear of obstacles and bystanders.
• Sharp Tools: Keep your axe and splitting maul sharp. A dull tool is more likely to glance off the wood and cause an injury.
• Proper Technique: Use proper technique when swinging an axe or splitting maul. Keep your back straight and your core engaged.
• Take Breaks: Don’t try to do too much at once. Take frequent breaks to avoid fatigue.

Firewood: Fuel Value Ratings and Storage Tips

Understanding the fuel value of different types of firewood and how to store it properly can help you get the most out of your wood-burning stove or fireplace.

Fuel Value Ratings: BTU Bonanza

The fuel value of firewood is measured in British Thermal Units (BTUs) per cord. A BTU is the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

Here’s a general ranking of common firewood types from highest to lowest BTU value:

• Osage Orange: (32.9 million BTU/cord) – This is the king of firewood. It burns hot and long, but it can be difficult to find.
• Hickory: (27.7 million BTU/cord) – Excellent heat output and a good aroma.
• Oak: (27.2 million BTU/cord) – A popular choice for firewood. It burns hot and long, but it takes longer to season than some other types of wood.
• Beech: (24.7 million BTU/cord) – Similar to oak in terms of heat output and burning characteristics.
• Maple: (24.0 million BTU/cord) – A good all-around firewood. It burns well and produces a moderate amount of heat.
• Ash: (23.6 million BTU/cord) – Easy to split and burns well, even when slightly green.
• Birch: (20.0 million BTU/cord) – Burns quickly and produces a good flame, but it doesn’t last as long as hardwoods.
• Pine: (15.8 million BTU/cord) – Easy to ignite and burns quickly, but it produces a lot of smoke and creosote.

Important Note: These are just general ratings. The actual BTU value of firewood can vary depending on the species, moisture content, and density of the wood.

Storage Tips: Keeping Your Firewood Dry and Ready

• Location: Store your firewood in a dry, well-ventilated area. Avoid storing firewood in damp basements or garages, as this can promote mold and decay.
• Elevation: Elevate the firewood off the ground to prevent moisture from wicking up into the wood. Use pallets, cinder blocks, or a dedicated firewood rack.
• Stacking: Stack the firewood neatly in a single row, with the bark facing up. This will help shed water and promote air circulation.
• Covering: Cover the top of the stack with a tarp or firewood cover to protect it from rain and snow. Leave the sides open for ventilation.
• Pest Control: Inspect your firewood regularly for signs of insects or pests. Store firewood away from your house to prevent pests from entering your home.

Data Point: According to the Environmental Protection Agency (EPA), burning seasoned firewood can reduce emissions of particulate matter by up to 50% compared to burning green firewood.

Actionable Tip: Create a firewood storage area that is both functional and aesthetically pleasing. A well-organized firewood stack can be a beautiful addition to your property.
