Felling Sight Techniques: 5 Pro Tips for Precise Tree Cutting

Understanding the Basics of Tree Felling

Before we get into the specific techniques, it’s essential to have a solid foundation in the fundamentals of tree felling. This isn’t just about knowing how to start your chainsaw; it’s about understanding the forces at play and the key elements that influence a tree’s fall.

• Tree Lean: This is the natural direction the tree wants to fall due to its growth pattern and weight distribution. Identifying the lean is the first and most crucial step.
• Wind: Wind can significantly alter the intended fall direction. Even a slight breeze can push a tree off course, so it’s vital to assess wind conditions carefully.
• Weight Distribution: Uneven branches or a heavier crown on one side will influence the tree’s balance and fall.
• Terrain: Sloping ground can make a tree slide or roll after it hits the ground, so consider the terrain’s impact.
• Obstacles: Identify any obstacles (other trees, power lines, buildings) that could interfere with the fall.

These factors are all interconnected, and a thorough assessment of each is essential for safe and precise felling. Ignoring even one can lead to unexpected and potentially dangerous outcomes.

Tip #1: Mastering the Hinge

The hinge is the single most important element in controlling the direction of a falling tree. It’s the strip of wood left uncut between the face cut and the back cut, and it acts as a rudder, guiding the tree as it falls.

• Hinge Size: The ideal hinge width is typically 80% of the tree’s diameter. For example, a 20-inch diameter tree would require a 16-inch wide hinge.
• Hinge Thickness: The hinge should be approximately 1/10 of the tree’s diameter. So, for a 20-inch tree, the hinge thickness would be about 2 inches.
• Hinge Placement: The hinge should be uniform in thickness and consistent across its width. Any variations can cause the tree to twist or fall unpredictably.

Why is the hinge so critical?

The hinge controls the speed and direction of the fall. A thicker hinge provides more control and prevents the tree from falling too quickly. A thinner hinge allows the tree to fall more rapidly but offers less control. The hinge also helps prevent the tree from barber-chairing, a dangerous situation where the tree splits vertically up the trunk.

My Experience:

I once felled a large oak tree where I underestimated the importance of a consistent hinge. I made the hinge slightly thicker on one side than the other. As the tree began to fall, it started to twist unexpectedly, narrowly missing a nearby shed. It was a stark reminder of the power of the hinge and the importance of precision.

Actionable Steps:

1. Practice: Use a smaller tree to practice making precise face cuts and back cuts, focusing on creating a uniform hinge.
2. Measure: Use a ruler or measuring tape to ensure the hinge width and thickness are accurate.
3. Inspect: Carefully inspect the hinge after making the cuts to identify any inconsistencies.

Tip #2: The Power of the Felling Lever (or Felling Wedge)

Sometimes, even with a perfectly executed hinge, a tree may hesitate to fall in the desired direction. This is where felling levers or wedges come into play. These tools provide the extra force needed to overcome friction and gravity, ensuring a controlled and predictable fall.

• Felling Lever: A long, metal bar with a curved end used to lift and push the tree over. It’s best suited for smaller trees, typically up to 12 inches in diameter.
• Felling Wedge: A wedge-shaped piece of plastic or metal inserted into the back cut to create leverage and push the tree over. Wedges are available in various sizes and materials (plastic, aluminum, magnesium).
• Hydraulic Jack: For very large trees, a hydraulic jack can provide significant lifting force.

How to Use a Felling Lever/Wedge:

1. Insert: Insert the felling lever or wedge into the back cut.
2. Apply Pressure: Use your body weight or a hammer to apply pressure to the lever or wedge.
3. Monitor: Observe the tree’s movement carefully, and adjust the pressure as needed.

Choosing the Right Tool:

• Tree Size: Felling levers are suitable for smaller trees, while wedges are more effective for larger trees. Hydraulic jacks are reserved for the largest and most challenging trees.
• Tree Lean: If the tree has a strong lean, a felling lever or wedge may not be necessary. However, if the lean is minimal or against the desired fall direction, these tools are essential.
• Wood Type: Hardwoods like oak and maple require more force to fell than softwoods like pine and fir.

My Experience:

I remember a time when I was felling a stand of aspen trees. The trees were relatively small, but they were tightly packed together, and several were leaning slightly against the desired fall direction. Without felling levers, it would have been nearly impossible to drop those trees safely and precisely.

Actionable Steps:

1. Invest: Purchase a good quality felling lever and several felling wedges of different sizes.
2. Practice: Practice using the lever and wedges on smaller trees to get a feel for how much force is required.
3. Maintain: Keep your felling lever and wedges clean and sharp.

Tip #3: The Importance of Back Cut Depth

The back cut is the final cut that severs the tree, leaving only the hinge intact. The depth of the back cut is critical for controlling the fall.

• Back Cut Depth: The back cut should be deep enough to leave the desired hinge width (80% of the tree’s diameter).
• Leaving Wood: Never cut completely through the tree. Always leave the hinge intact.
• Boring Cut: For larger trees, consider using a boring cut (plunge cut) to create the back cut. This involves inserting the saw into the tree and cutting outwards, leaving a uniform hinge.

Why is Back Cut Depth Important?

If the back cut is too shallow, the hinge will be too wide, and the tree may fall backward or barber-chair. If the back cut is too deep, the hinge will be too narrow, and the tree may fall uncontrollably.

My Experience:

Early in my career, I made the mistake of cutting the back cut too deep on a large pine tree. As the tree began to fall, the hinge snapped prematurely, and the tree fell much faster than I anticipated. Luckily, no one was hurt, but it was a close call.

Actionable Steps:

1. Measure: Use a measuring tape to accurately measure the depth of your back cut.
2. Visualize: Before making the cut, visualize the desired hinge width and thickness.
3. Adjust: If you accidentally cut the back cut too deep, use wedges to stabilize the tree and prevent it from falling prematurely.

Tip #4: Using Sighting Techniques

Sighting techniques are visual methods used to determine the direction a tree will fall. They involve using reference points to align your cuts and ensure the tree falls in the desired location.

• The Gun Sight Method: This involves aligning the top of your chainsaw bar with a distant object in the desired fall direction. This creates a visual line that helps you maintain a consistent cutting angle.
• The Branch Sighting Method: This involves identifying a specific branch or feature on the tree that aligns with the desired fall direction. Use this branch as a visual reference point while making your cuts.
• The Plumb Bob Method: This involves using a plumb bob (a weight suspended from a string) to determine the vertical axis of the tree. This helps you identify the tree’s lean and ensure your cuts are perpendicular to the lean.

How to Use Sighting Techniques:

1. Identify: Identify a suitable reference point in the desired fall direction.
2. Align: Align your chainsaw bar or the tree’s branch with the reference point.
3. Maintain: Maintain the alignment while making your cuts.

My Experience:

I often use the gun sight method when felling trees in open areas. I’ll pick a distant tree or landmark and use it as a reference point to ensure my cuts are aligned. This technique has significantly improved my accuracy and reduced the number of times I’ve had to use wedges to correct the fall direction.

Actionable Steps:

1. Practice: Practice using the different sighting techniques in various situations.
2. Experiment: Experiment with different reference points to find what works best for you.
3. Adapt: Adapt your sighting techniques based on the terrain, wind conditions, and tree characteristics.

Tip #5: Reading the Tree

This is perhaps the most nuanced and important skill in precise tree felling. It involves carefully observing the tree’s characteristics and using that information to predict its behavior during the fall.

• Crown Shape: The shape of the tree’s crown can indicate its weight distribution and lean. A heavier crown on one side will cause the tree to fall in that direction.
• Branch Distribution: Uneven branch distribution can also influence the tree’s balance.
• Trunk Defects: Cracks, knots, and other defects in the trunk can weaken the tree and affect its fall.
• Root System: Inspect the root system for any signs of decay or damage. A compromised root system can make the tree unstable and unpredictable.
• Species: Different tree species have different wood densities and growth patterns, which can affect their felling characteristics. For example, hardwoods like oak and maple are denser and require more force to fell than softwoods like pine and fir.

How to Read the Tree:

1. Observe: Carefully observe the tree from all angles.
2. Analyze: Analyze the tree’s characteristics and identify any potential hazards or challenges.
3. Predict: Predict how the tree will behave during the fall based on your observations.

My Experience:

I once encountered a large, seemingly healthy maple tree that I was planning to fell. However, upon closer inspection, I noticed a large crack running up the trunk on one side. This indicated that the tree was significantly weakened and could potentially split unexpectedly during the fall. I adjusted my felling plan accordingly, using extra wedges and taking extra precautions to ensure a safe and controlled fall.

Actionable Steps:

1. Study: Study the characteristics of different tree species.
2. Practice: Practice observing trees and identifying potential hazards.
3. Learn: Learn from your mistakes and continuously refine your ability to read trees.

Safety First: Essential Precautions for Tree Felling

No discussion of tree felling would be complete without emphasizing the paramount importance of safety. Tree felling is inherently dangerous, and complacency can have devastating consequences.

• Personal Protective Equipment (PPE): Always wear appropriate PPE, including a hard hat, eye protection, hearing protection, chainsaw chaps, and sturdy boots.
• Chainsaw Maintenance: Keep your chainsaw in good working order. A dull or poorly maintained saw is more likely to kickback or malfunction.
• Clear the Work Area: Clear the area around the tree of any obstacles or debris.
• Escape Route: Plan an escape route before making any cuts.
• Communication: Communicate with your team members and ensure everyone is aware of the felling plan.
• First Aid: Have a well-stocked first aid kit readily available.
• Know Your Limits: Don’t attempt to fell trees that are beyond your skill level or experience.

Statistics:

According to the Occupational Safety and Health Administration (OSHA), logging is one of the most dangerous occupations in the United States. The fatality rate for logging workers is significantly higher than the national average for all occupations. Common causes of logging fatalities include being struck by falling trees, chainsaw injuries, and equipment malfunctions.

My Experience:

I’ve witnessed firsthand the devastating consequences of neglecting safety precautions. I once saw a fellow logger suffer a severe leg injury when a tree he was felling kicked back unexpectedly. He wasn’t wearing chainsaw chaps, and the saw cut deep into his leg. It was a painful and preventable accident that served as a stark reminder of the importance of PPE.

Actionable Steps:

1. Invest: Invest in high-quality PPE.
2. Maintain: Regularly inspect and maintain your chainsaw and other equipment.
3. Train: Participate in professional tree felling training courses.
4. Review: Review safety procedures before each felling operation.

Advanced Techniques for Challenging Trees

While the previous tips cover the fundamentals of precise tree felling, some trees present unique challenges that require more advanced techniques.

• Leaning Trees: Trees with a significant lean require careful planning and execution. Use wedges and felling levers to overcome the lean and control the fall direction.
• Hanging Trees: A hanging tree is a tree that gets caught in another tree during the fall. This is a dangerous situation that requires specialized equipment and techniques to resolve safely. Never attempt to climb a hanging tree. Use a winch or cable to pull the tree down from a safe distance.
• Large Diameter Trees: Felling very large trees requires specialized equipment and techniques, such as using a hydraulic jack or a large chainsaw with a long bar.
• Decayed Trees: Decayed trees are unpredictable and dangerous. They can split or collapse unexpectedly during the fall. Exercise extreme caution when felling decayed trees.

My Experience:

I once had to fell a massive oak tree that was leaning heavily towards a nearby house. The tree was also partially decayed, making it even more challenging. I used a combination of wedges, a hydraulic jack, and a long-bar chainsaw to carefully control the fall and prevent any damage to the house. It was a complex and stressful operation, but ultimately successful.

Actionable Steps:

1. Seek Training: Seek specialized training in advanced tree felling techniques.
2. Use Appropriate Equipment: Use the appropriate equipment for the job.
3. Assess Risks: Carefully assess the risks and develop a detailed felling plan.
4. Don’t Hesitate to Call for Help: If you’re unsure about how to fell a challenging tree, don’t hesitate to call for help from a qualified professional.
