Want to fell trees like a pro and avoid those heart-stopping near misses? Mastering the art of notching is your quick win. By understanding and applying these five professional cuts, you’ll gain control over the direction of the fall, making your work safer and more efficient. Let’s dive in!

Notch Tree Techniques (5 Pro Cuts for Safer Felling)

Felling trees safely and predictably is a crucial skill for anyone working with wood, whether you’re a seasoned logger, a weekend woodcutter, or simply managing your property. The notch, or face cut, is the foundation of controlled felling. It dictates the direction the tree will fall, and a poorly executed notch can lead to dangerous and unpredictable results. Over the years, I’ve seen firsthand the consequences of neglecting proper notching techniques – from near misses to equipment damage.

Why Notching Matters: Controlling the Fall

The notch serves two primary purposes:

• Directional Control: The angle and depth of the notch determine the direction in which the tree will lean and eventually fall.
• Preventing Barber Chairs: A properly executed notch helps prevent the tree from splitting upwards during the fall, a dangerous phenomenon known as a “barber chair.”

Think of the notch as a hinge. You’re weakening the tree on one side, forcing it to bend and eventually break in the direction you’ve chosen. The more precise your notch, the more control you have.

Understanding Wood Anatomy: A Foundation for Safe Felling

Before we jump into the cuts themselves, it’s essential to understand some basic wood anatomy. Knowing how a tree is structured will help you predict its behavior during felling.

• Heartwood: The central, older wood of the tree. It’s generally denser and more resistant to decay.
• Sapwood: The outer, younger wood that transports water and nutrients. It’s typically lighter in color and more susceptible to decay.
• Cambium: A thin layer of cells between the sapwood and the bark, responsible for the tree’s growth.
• Bark: The outer protective layer.

The grain of the wood also plays a crucial role. Trees with straight grain are generally easier to fell predictably. Trees with spiral grain, knots, or other irregularities can be more challenging and require extra caution.

Data Point: The moisture content of wood significantly affects its weight and strength. Green wood (freshly cut) can weigh twice as much as seasoned wood. This extra weight can make felling more difficult and increase the risk of injury.

Essential Tools for Notch Tree Techniques

Having the right tools and keeping them in good condition is paramount for safe and efficient felling. Here’s a breakdown of the essential equipment:

• Chainsaw: Choose a chainsaw appropriate for the size of the trees you’ll be felling. A larger saw offers more power but can be more difficult to handle. Ensure your chain is sharp and properly tensioned.
• Felling Axe or Hatchet: Used for driving wedges and making minor adjustments.
• Wedges: Plastic or aluminum wedges are essential for preventing the tree from pinching your saw and for helping to direct the fall.
• Measuring Tape or Felling Bar: To ensure accurate notch depth and hinge wood thickness.
• Personal Protective Equipment (PPE): This includes a helmet, eye protection, hearing protection, chainsaw chaps, gloves, and sturdy boots.

Tool Maintenance Best Practices:

• Sharpen your chainsaw chain regularly: A dull chain increases the risk of kickback and makes cutting more difficult.
• Clean your chainsaw after each use: Remove sawdust and debris to prevent overheating and wear.
• Inspect your equipment before each use: Check for loose bolts, damaged parts, and other potential hazards.

The 5 Pro Notch Tree Techniques

Now, let’s explore the five professional notch tree techniques that will elevate your felling skills:

1. The Conventional Notch (Open Face Notch)

This is the most common and versatile notching technique. It’s suitable for trees of all sizes and is relatively easy to learn.

• Description: The conventional notch consists of two cuts: a top cut angled downwards and a bottom cut angled upwards, meeting at a point. The angle of the top cut typically ranges from 45 to 60 degrees.
• Ideal For: General felling, trees with minimal lean.

• Steps:

  1. Assess the Lean: Determine the natural lean of the tree and choose your desired felling direction.
  2. Establish the Notch Depth: The notch depth should be approximately 20-30% of the tree’s diameter.
  3. Make the Top Cut: Start with the top cut, angling downwards towards the desired meeting point.
  4. Make the Bottom Cut: Make the bottom cut, angling upwards to meet the top cut.
  5. Clean the Notch: Remove any loose wood or debris from the notch.

• Pros: Easy to learn, versatile.

• Cons: Can be prone to barber chairs if not executed properly, less effective on trees with a strong lean.

Real-World Example: I once used the conventional notch to fell a large oak tree in my backyard. The tree had a slight lean towards my neighbor’s property, so I carefully planned my notch to ensure it fell safely in the opposite direction. By taking my time and making accurate cuts, I was able to fell the tree exactly where I wanted it, avoiding any damage to my neighbor’s property.

2. The Humboldt Notch (Undercut Notch)

This notch is characterized by an inverted cut, where the bottom cut is made first, followed by the top cut.

• Description: The Humboldt notch features a horizontal bottom cut followed by an angled top cut that meets the bottom cut.
• Ideal For: Trees with a strong lean or back lean, preventing barber chairs.

• Steps:

  1. Assess the Lean: Determine the lean of the tree. This notch is especially useful if the tree leans backwards.
  2. Make the Bottom Cut: Start with a horizontal cut at the desired notch depth (20-30% of the tree’s diameter).
  3. Make the Top Cut: Make the top cut, angling downwards to meet the bottom cut.
  4. Clean the Notch: Remove any loose wood or debris.

• Pros: Excellent for controlling trees with a strong lean, reduces the risk of barber chairs.

• Cons: Requires more precision, can be more difficult to execute than the conventional notch.

Unique Insight: The Humboldt notch gets its name from the Humboldt region of California, where it was developed for felling large redwood trees with significant lean.

3. The Open Face Notch (90-Degree Notch)

This notch involves a wider angle between the top and bottom cuts, typically around 90 degrees or more.

• Description: The open face notch has a wider angle, providing greater control over the direction of the fall.
• Ideal For: Precise directional felling, trees with unpredictable grain.

• Steps:

  1. Assess the Lean: Determine the lean and desired felling direction.
  2. Establish the Notch Depth: Aim for a notch depth of 20-30% of the tree’s diameter.
  3. Make the Top Cut: Start with the top cut, angling downwards at a steeper angle than the conventional notch.
  4. Make the Bottom Cut: Make the bottom cut, angling upwards to meet the top cut, creating a wider opening.
  5. Clean the Notch: Remove any loose wood or debris.

• Pros: Provides excellent directional control, reduces the risk of barber chairs.

• Cons: Requires more experience, can be more time-consuming to execute.

Case Study: I once used the open face notch to fell a tree near a power line. The tree had a slight lean towards the power line, and I needed to ensure it fell in the opposite direction. By using the open face notch and carefully placing my wedges, I was able to fell the tree safely and avoid any contact with the power line.

4. The Side Notch (Lateral Notch)

This technique involves creating a notch on the side of the tree, rather than directly in the direction of the fall.

• Description: The side notch is used to pull the tree to the side during the fall.
• Ideal For: Felling trees in tight spaces, redirecting the fall.

• Steps:

  1. Assess the Situation: Determine the desired felling direction and the obstacles you need to avoid.
  2. Make the Side Notch: Create a notch on the side of the tree, angled towards the desired direction of pull.
  3. Make the Felling Cut: Make the felling cut, leaving a hinge of appropriate thickness.
  4. Use Wedges: Drive wedges into the felling cut to help redirect the fall.

• Pros: Useful for felling trees in confined spaces, allows for precise directional control.

• Cons: Requires significant experience, can be more complex to execute.

Personalized Storytelling: I remember a time when I had to fell a tree that was leaning precariously close to a shed. There was no room to fell the tree in its natural direction, so I used a side notch to pull it away from the shed. It was a challenging situation, but with careful planning and execution, I was able to fell the tree safely and avoid any damage to the shed.

5. The Bore Cut Notch (Boring Method)

This technique involves boring into the tree to create the notch from the inside out.

• Description: The bore cut notch involves boring into the tree to create the notch from the inside out.
• Ideal For: Large trees, preventing barber chairs, complex situations.

• Steps:

  1. Assess the Tree: Determine the size and lean of the tree.
  2. Make a Bore Cut: Carefully bore into the tree, starting on the side opposite the desired felling direction.
  3. Create the Notch: Use the bore cut as a starting point to create the desired notch shape.
  4. Make the Felling Cut: Make the felling cut, leaving a hinge of appropriate thickness.

• Pros: Excellent for preventing barber chairs, provides precise control over the fall.

• Cons: Requires significant experience and specialized equipment, can be dangerous if not executed properly.

Actionable Advice: Before attempting the bore cut notch, practice on smaller trees to gain experience and confidence. Always use extreme caution and follow all safety guidelines.

The Importance of the Hinge

Regardless of the notching technique you choose, the hinge is a critical element of controlled felling. The hinge is the strip of uncut wood left between the notch and the felling cut. It acts as a guide, controlling the speed and direction of the fall.

• Hinge Thickness: The ideal hinge thickness is typically around 10% of the tree’s diameter.
• Hinge Width: The hinge should be as wide as the notch opening.
• Maintaining a Consistent Hinge: A consistent hinge is essential for a controlled fall. Avoid cutting into the hinge during the felling cut.

Data Point: Studies have shown that trees with properly sized and maintained hinges are significantly less likely to barber chair.

Felling Cut Techniques: Completing the Process

Once you’ve created the notch, the next step is to make the felling cut. Here are a few common felling cut techniques:

• Straight Cut: A simple horizontal cut made directly behind the notch.
• Bore Cut Felling Cut: Using the bore cut method to sever the remaining wood fibers.
• Wedging: Using wedges to help push the tree over and prevent pinching.

Safety Considerations:

• Always be aware of your surroundings: Identify potential hazards such as power lines, buildings, and people.
• Establish escape routes: Plan two clear escape routes away from the tree in case of an emergency.
• Never turn your back on a falling tree: Watch the tree carefully as it falls and be prepared to move quickly if necessary.

Firewood Seasoning: From Tree to Fuel

After felling the tree, the next step is to process it into firewood. Proper seasoning is crucial for maximizing the fuel value of your firewood and reducing smoke.

• Why Season Firewood? Green wood contains a high percentage of moisture, which reduces its burning efficiency and produces excessive smoke. Seasoning allows the moisture to evaporate, resulting in hotter, cleaner-burning fires.
• Ideal Moisture Content: Firewood should have a moisture content of 20% or less for optimal burning.
• Seasoning Time: The amount of time it takes to season firewood depends on the type of wood, the climate, and the storage conditions. Generally, hardwoods require at least six months to a year of seasoning, while softwoods can be seasoned in as little as three months.

Firewood Seasoning Techniques:

• Splitting: Splitting firewood increases the surface area, allowing moisture to evaporate more quickly.
• Stacking: Stack firewood in a single row, off the ground, with good air circulation.
• Covering: Cover the top of the firewood pile to protect it from rain and snow, but leave the sides open for ventilation.

Data Point: Properly seasoned firewood can produce up to 50% more heat than green wood.

Hardwood vs. Softwood: Understanding Fuel Value

The type of wood you burn also affects its fuel value. Hardwoods are generally denser and contain more energy per unit volume than softwoods.

• Hardwoods: Oak, maple, ash, birch, and beech are all excellent choices for firewood. They burn longer and produce more heat.
• Softwoods: Pine, fir, spruce, and cedar are less dense and burn more quickly. They are often used for kindling or starting fires.

Comparison Table:

Fuel Value Ratings: BTU (British Thermal Units) is a measure of the heat content of fuel. The higher the BTU rating, the more heat the wood will produce.

Chainsaw Safety: A Non-Negotiable Priority

Chainsaw safety should always be your top priority when felling trees and processing firewood. Here are some essential safety tips:

• Read the Owner’s Manual: Familiarize yourself with the chainsaw’s features, safety precautions, and maintenance requirements.
• Wear Proper PPE: Always wear a helmet, eye protection, hearing protection, chainsaw chaps, gloves, and sturdy boots.
• Maintain a Safe Distance: Keep bystanders at least two tree lengths away from the felling area.
• Avoid Cutting Above Your Head: Cutting above your head is dangerous and increases the risk of losing control of the chainsaw.
• Be Aware of Kickback: Kickback is a sudden and forceful upward or backward movement of the chainsaw that can cause serious injury.
• Never Cut with a Dull Chain: A dull chain increases the risk of kickback and makes cutting more difficult.
• Take Breaks: Chainsaw work can be physically demanding. Take frequent breaks to avoid fatigue.

Current Industry Statistics: According to the U.S. Consumer Product Safety Commission, there are approximately 30,000 chainsaw-related injuries each year. Most of these injuries are preventable with proper training and safety precautions.

Project Planning and Execution: A Step-by-Step Approach

Before you start felling trees, it’s essential to plan your project carefully. Here’s a step-by-step approach:

1. Assess the Site: Identify potential hazards such as power lines, buildings, and obstacles.
2. Determine the Felling Direction: Choose the safest and most practical felling direction.
3. Select the Appropriate Notching Technique: Choose the notching technique that is best suited for the tree’s size, lean, and location.
4. Prepare Your Equipment: Ensure your chainsaw is in good working order and that you have all the necessary tools and PPE.
5. Communicate with Others: Let others know your plans and ensure they are aware of the potential hazards.
6. Execute the Felling Plan: Follow your plan carefully and be prepared to adjust as needed.
7. Process the Wood: Cut the tree into manageable lengths and split it for seasoning.
8. Stack the Firewood: Stack the firewood in a single row, off the ground, with good air circulation.
