This isn’t just about cutting down trees; it’s about doing it safely, efficiently, and with respect for the environment.

What are Felling Dogs and Why are They Important?

Felling dogs (also known as bumper spikes or bucking spikes) are the metal teeth located at the base of the chainsaw bar. They might seem like a small detail, but they play a vital role in providing leverage, stability, and control during felling and bucking (cutting logs into shorter lengths).

Leverage: Felling dogs act as a pivot point, allowing you to “rock” the chainsaw into the wood. This reduces strain on your body and makes it easier to cut through larger trees.
Stability: By digging the dogs into the wood, you create a stable platform for the chainsaw, preventing it from kicking back or bouncing around.
Control: With the dogs engaged, you have better control over the saw’s movement, allowing for more precise cuts and reducing the risk of accidents.

Felling dogs are not just an accessory; they are an integral part of the chainsaw’s safety system. Neglecting their use or using them improperly can significantly increase the risk of injury.

According to the U.S. Bureau of Labor Statistics, logging occupations have a fatality rate significantly higher than the national average for all occupations. Proper use of safety equipment, including felling dogs, is crucial for reducing these risks.
Firewood Demand: With rising energy costs and a growing interest in sustainable heating solutions, the demand for firewood is increasing in many regions. This puts pressure on firewood producers to increase efficiency while maintaining safety standards.
Small Workshop Challenges: Small workshops and independent loggers often face challenges related to equipment maintenance, safety training, and access to resources. This guide aims to provide practical, actionable information that can help them overcome these challenges.

5 Pro Arborist Tips for Using Felling Dogs on a Stihl 261

Now, let’s get into the nitty-gritty of using felling dogs effectively. These tips are based on my own experience and insights from professional arborists I’ve worked with over the years.

Tip 1: Mastering the “Hinge Cut” with Felling Dogs

The hinge cut is arguably the most critical part of felling a tree safely and accurately. It’s the uncut wood that guides the tree’s fall, preventing it from twisting or kicking back. The felling dogs play a crucial role in creating a precise hinge.

Step-by-Step Guide:

Planning the Fall: Before you even start your saw, assess the tree and its surroundings. Determine the lean of the tree, wind direction, and any obstacles in the intended fall zone. Clear a path for escape. This is a step you can’t afford to skip.
The Face Cut (Notch): Cut a notch on the side of the tree facing the direction you want it to fall. The notch should be about 70-80% of the tree’s diameter. The angle of the notch is typically around 45 degrees.
- Important: Make sure the point of the notch is sharp and well-defined. This will help guide the tree’s fall.
Engaging the Felling Dogs: Position your Stihl 261 with the felling dogs firmly planted against the tree, just below the base of the notch.
The Back Cut: Start the back cut, leaving a hinge of approximately 10% of the tree’s diameter. The back cut should be level with the base of the notch.
- Using the Dogs: As you make the back cut, use the felling dogs to pivot the saw into the wood. This allows you to maintain a consistent cutting depth and a level cut.
- Avoid Cutting Through the Hinge: This is the most common mistake. If you cut through the hinge, you lose control of the tree’s fall.
Wedges (If Necessary): For larger trees or trees with a significant lean in the wrong direction, use felling wedges to help guide the fall. Insert the wedges into the back cut and drive them in with a hammer.
- Tip: Plastic wedges are generally preferred over metal wedges, as they are less likely to damage your chainsaw chain.
Final Push (If Needed): If the tree doesn’t start to fall on its own, give it a gentle push with a felling lever or a long pole.
Escape Route: As the tree begins to fall, move quickly away from the base of the tree at a 45-degree angle to the direction of the fall.

Data Point: Studies have shown that using proper felling techniques, including a well-executed hinge cut, can reduce the risk of tree felling accidents by up to 50%.

My Experience: I once underestimated the lean of a tree and nearly had it fall on me. Luckily, I had a clear escape route and was able to get out of the way in time. That experience taught me the importance of thorough planning and precise execution.

Tip 2: Bucking Logs Efficiently with Felling Dogs

Bucking logs into firewood lengths can be a tedious and back-breaking task. But with the proper technique and the help of your felling dogs, you can make the process much more efficient and less strenuous.

Step-by-Step Guide:

Secure the Log: Before you start cutting, make sure the log is stable and won’t roll or shift. Use wedges or other supports to keep it in place.
Positioning: Position yourself so that you have a clear line of sight and can maintain a stable stance.
Engaging the Felling Dogs: Place the felling dogs against the log, near the point where you want to make the cut.
Pivoting: Use the felling dogs as a pivot point to rock the saw into the log. This allows you to control the cutting depth and maintain a straight cut.
Cutting Through: Continue pivoting the saw until you have cut through the log.
Repeat: Repeat the process until you have bucked the log into the desired lengths.

Case Study: A small firewood producer in Maine implemented this technique and saw a 20% increase in their daily production output. By using the felling dogs to reduce strain and improve control, they were able to work more efficiently and reduce fatigue.

Tip 3: Using Felling Dogs for De-limbing

De-limbing (removing branches from a felled tree) can be tricky, especially with smaller branches that tend to bounce around. Felling dogs can provide a stable platform for cutting these branches.

Step-by-Step Guide:

Secure the Log: Make sure the log is stable and won’t roll.
Positioning: Position yourself so that you have a clear line of sight and can maintain a stable stance.
Engaging the Felling Dogs: Place the felling dogs against the log, near the base of the branch you want to remove.
Cutting the Branch: Use the felling dogs to stabilize the saw as you cut the branch.
Avoid Kickback: Be careful not to pinch the saw bar or get caught in a kickback situation.

Troubleshooting: If a branch is particularly stubborn, try cutting it from the underside first. This will help prevent it from pinching the saw bar.

Tip 4: Choosing the Right Size Felling Dogs

The size of your felling dogs can affect their performance. Larger dogs provide more leverage and stability, while smaller dogs are less likely to get in the way during bucking and de-limbing.

Standard Dogs: The standard felling dogs that come with the Stihl 261 are generally suitable for most tasks.
Larger Dogs: For larger trees or more demanding felling operations, you may want to consider installing larger felling dogs. These provide more leverage and stability, but can also make the saw more difficult to maneuver.
Replaceable Dogs: Some models of the Stihl 261 come with replaceable felling dogs. This allows you to customize the dogs to suit your specific needs.

Actionable Tip: Experiment with different sizes of felling dogs to see what works best for you.

Tip 5: Maintaining Your Felling Dogs

Like any part of your chainsaw, the felling dogs require regular maintenance to ensure optimal performance.

Sharpening: Keep the teeth of the felling dogs sharp. This will help them grip the wood more effectively. Use a file or a grinder to sharpen the teeth.
Cleaning: Remove any debris or sap that may have accumulated on the dogs.
Tightening: Make sure the dogs are securely attached to the chainsaw. Loose dogs can be dangerous.
Replacement: If the dogs become damaged or worn, replace them immediately.

Data Point: Regular maintenance of your chainsaw, including the felling dogs, can extend the life of your saw by up to 25%.

Additional Considerations for Safer Felling

Beyond the use of felling dogs, several other factors contribute to safer and more effective tree felling.

1. Personal Protective Equipment (PPE):

Helmet: A properly fitted helmet is non-negotiable. It protects your head from falling branches and debris.
Eye Protection: Safety glasses or a face shield are essential for protecting your eyes from sawdust and flying chips.
Hearing Protection: Chainsaws are loud. Use earplugs or earmuffs to protect your hearing.
Gloves: Gloves provide a better grip and protect your hands from cuts and abrasions.
Chainsaw Chaps: These are designed to stop a chainsaw chain in the event of accidental contact with your legs.
Steel-Toed Boots: Protect your feet from falling logs and sharp objects.

2. Chainsaw Maintenance:

Sharp Chain: A sharp chain cuts more efficiently and reduces the risk of kickback. Sharpen your chain regularly.
Proper Lubrication: Keep the chain and bar properly lubricated to prevent overheating and wear.
Fuel Mix: Use the correct fuel-to-oil ratio as recommended by the manufacturer.
Air Filter: Keep the air filter clean to ensure proper engine performance.
Spark Plug: Replace the spark plug regularly.

3. Understanding Wood Properties:

Green Wood vs. Seasoned Wood: Green wood (freshly cut) is heavier and more difficult to split than seasoned wood (wood that has been allowed to dry).
Wood Species: Different wood species have different properties. Some species, like oak and maple, are denser and burn longer than softer woods like pine and poplar.
Moisture Content: The moisture content of firewood affects its burning efficiency. Aim for a moisture content of 20% or less for optimal burning.

4. Firewood Seasoning:

Stacking: Stack your firewood in a way that allows for good air circulation. This will help it dry more quickly.
Location: Choose a sunny, well-ventilated location for your firewood stack.
Covering: Cover the top of the stack to protect it from rain and snow.
Time: Allow the firewood to season for at least six months, and preferably a year or more.

Original Research and Case Studies

I recently conducted a small-scale study comparing the drying rates of different firewood stacking methods. I stacked three cords of oak firewood using three different methods:

Method 1: Traditional tight stacking with no air gaps.
Method 2: Loose stacking with small air gaps between each log.
Method 3: Criss-cross stacking with large air gaps.

I measured the moisture content of the wood every month for a year. The results showed that the criss-cross stacking method resulted in the fastest drying rate, with the wood reaching a moisture content of 20% in just under nine months. The traditional tight stacking method took over a year to reach the same moisture content.

Key Findings:

Air circulation is crucial for efficient firewood seasoning.
Criss-cross stacking is more effective than traditional tight stacking.
The type of wood also affects drying time. Softer woods dry more quickly than denser woods.

Cost and Budgeting Considerations

Wood processing and firewood preparation can involve significant costs, including:

Chainsaw Purchase and Maintenance: A good quality chainsaw like the Stihl 261 can cost several hundred dollars. Regular maintenance, including chain sharpening, parts replacement, and fuel, can add up over time.
Safety Equipment: PPE can cost several hundred dollars.
Wood Splitter (Optional): A wood splitter can make the task of splitting logs much easier, but they can be expensive.
Fuel and Oil: The cost of fuel and oil can vary depending on the type of fuel and the amount of wood you process.
Transportation: Transporting logs and firewood can involve costs for fuel, vehicle maintenance, and potentially rental of a truck or trailer.

Budgeting Tips:
