How to Fell a Tree: Precision Tips for Small Diameter Logs (Pro Arborist Hacks)
Felling Small Diameter Trees: A Pro’s Guide to Precision and Safety
The user intent behind searching for “How to Fell a Tree: Precision Tips for Small Diameter Logs (Pro Arborist Hacks)” is clear: individuals want to learn how to safely and efficiently fell smaller trees, incorporating techniques used by professional arborists. This section aims to satisfy that intent by providing a detailed, step-by-step guide.
1. Assessing the Tree and Surroundings
Before even thinking about starting your chainsaw, a thorough assessment is crucial. This isn’t just about looking at the tree; it’s about understanding its relationship to its environment.
- Tree Lean: Is the tree leaning in a particular direction? Gravity will be your guiding force, but also a potential hazard.
- Branch Distribution: Are there significantly heavier branches on one side? This will influence the direction of the fall.
- Wind Conditions: Even a slight breeze can dramatically alter the tree’s trajectory. Never fell trees in high winds.
- Obstacles: Identify any obstacles in the potential fall zone, such as power lines, fences, buildings, or other trees.
- Escape Routes: Plan two clear escape routes at a 45-degree angle away from the anticipated direction of the fall.
2. Personal Protective Equipment (PPE): Gear Up for Safety
No professional would ever compromise on safety, and neither should you. The following PPE is non-negotiable:
- Chainsaw Helmet: Protects your head from falling branches and kickback.
- Eye Protection: Safety glasses or a face shield are essential for deflecting wood chips and debris.
- Hearing Protection: Chainsaws are loud. Prolonged exposure can cause permanent hearing damage.
- Chainsaw Chaps: These ballistic nylon chaps are designed to stop a chainsaw chain in the event of accidental contact with your legs.
- Gloves: Provide a secure grip and protect your hands from cuts and abrasions.
- Steel-Toed Boots: Essential for protecting your feet from falling logs and sharp objects.
3. Chainsaw Selection and Maintenance
The right chainsaw and proper maintenance are critical for both efficiency and safety.
- Chainsaw Size: For small diameter trees (typically under 12 inches), a smaller chainsaw with a bar length of 14-16 inches is usually sufficient. Avoid using an oversized chainsaw; it can be unwieldy and increase the risk of accidents.
- Chain Sharpness: A dull chain is a dangerous chain. Sharpen your chain regularly or replace it when necessary. A sharp chain cuts smoothly and reduces the risk of kickback.
- Chain Tension: Ensure the chain is properly tensioned. Too loose, and it can derail; too tight, and it can bind.
- Lubrication: Keep the chain lubricated with chainsaw bar oil. This reduces friction and prolongs the life of the chain and bar.
- Fuel Mixture: Use the correct fuel-to-oil ratio as specified by the chainsaw manufacturer.
4. The Felling Cut: A Step-by-Step Guide
This is where precision comes into play. The felling cut consists of three main components: the notch, the back cut, and the hinge.
- The Notch (Face Cut):
- The notch determines the direction of the fall. It should be cut on the side of the tree facing the desired direction.
- The notch typically consists of two cuts: a top cut at a 45-degree angle and a horizontal bottom cut that meets the top cut.
- The depth of the notch should be approximately 1/5 to 1/3 of the tree’s diameter.
- The Hinge:
- The hinge is the uncut wood between the notch and the back cut. It controls the fall of the tree and prevents it from kicking back towards you.
- The hinge should be of uniform thickness and approximately 1/10 of the tree’s diameter.
- The Back Cut:
- The back cut is made on the opposite side of the tree from the notch, slightly above the horizontal cut of the notch.
- Leave approximately 1-2 inches of wood between the back cut and the notch to create the hinge.
- Once the back cut is complete, the tree should begin to fall in the direction of the notch.
5. Advanced Techniques for Small Diameter Logs
Professional arborists use several advanced techniques that can be adapted for smaller trees.
- Using Felling Wedges: For trees that are leaning slightly against the desired direction of fall, felling wedges can be driven into the back cut to help push the tree over.
- Pulling Ropes: In situations where you need precise control over the fall, a rope can be attached to the upper part of the tree and pulled in the desired direction as the back cut is completed. This is especially useful near obstacles.
- Boring Cut: For larger diameter small trees (approaching the limit of what’s considered “small”), a boring cut can be used. This involves plunging the tip of the chainsaw bar into the tree to create a cavity before making the back cut. This technique helps to prevent the tree from splitting or barber-chairing (splitting upwards) during the fall.
6. Dealing with Hung-Up Trees
Occasionally, a tree may become hung up in another tree. This is a dangerous situation that requires careful consideration.
- Never climb a hung-up tree or attempt to cut it down from the tree it’s leaning on.
- Use a peavey or a cant hook to try to roll the hung-up log free.
- If you cannot safely dislodge the tree, call a professional arborist.
7. Post-Felling Procedures
Once the tree is on the ground, take a moment to assess the situation and ensure the area is safe.
- Delimb the Tree: Remove the branches using your chainsaw or a hatchet.
- Buck the Tree: Cut the trunk into manageable lengths for processing or firewood.
- Stack the Wood: Properly stack the wood to allow for air circulation and drying.
Project Metrics and KPIs for Wood Processing and Firewood Preparation
Now, let’s transition into the core of this article: tracking project metrics and KPIs. This is where I’ll share my personalized stories, experiences, and unique insights related to measuring project success in wood processing and firewood preparation.
Why track metrics? Because what gets measured, gets managed. I’ve seen firsthand how tracking even simple metrics can significantly improve efficiency, reduce waste, and increase profitability.
1. Wood Volume Yield

- Why It’s Important: This metric directly reflects the efficiency of your wood processing operation. A higher yield means more usable wood from the same amount of raw material.
- How to Interpret It: Track your yield over time. A consistent decline could indicate issues with your processing techniques, equipment, or raw material quality.
- How It Relates to Other Metrics: Wood volume yield is directly related to wood waste, processing time, and equipment efficiency.
- Example: Let’s say I start with 10 cords of mixed hardwood. After processing, I end up with 7 cords of firewood and 1 cord of wood chips (which I use for landscaping). My wood volume yield for firewood is 70%.
2. Wood Waste Percentage
- Definition: The percentage of raw wood material that is discarded as waste during processing. This includes sawdust, bark, unusable pieces, and rotten wood.
- Why It’s Important: Minimizing wood waste reduces costs associated with disposal, increases the overall efficiency of your operation, and can even improve your environmental footprint.
- How to Interpret It: A high wood waste percentage indicates inefficiencies in your processing methods or potentially poor quality raw materials.
- How It Relates to Other Metrics: Directly impacts wood volume yield, processing costs, and fuel consumption.
- Example: In the example above, I started with 10 cords and ended up with 8 cords of usable product (7 firewood + 1 chips). That means 2 cords were wasted. My wood waste percentage is 20%.
- My Story: I once worked on a project where the wood waste percentage was a staggering 40%. By analyzing our cutting patterns and investing in a better log splitter, we reduced it to 15% within a few months. This resulted in significant cost savings and a more sustainable operation.
3. Processing Time per Cord
- Definition: The average time it takes to process one cord of wood, from raw logs to finished product (e.g., firewood, lumber).
