Felling: Bringing Down Trees Safely and Effectively

Felling is the process of cutting down a tree. It’s a complex and potentially dangerous task that requires careful planning and execution.

1. Assessing the Tree and Surroundings:

Tree Lean: Determine the direction the tree is leaning. This will influence the direction of fall.
Wind: Consider the wind direction. Wind can significantly affect the tree’s fall.
Obstacles: Identify any obstacles in the tree’s path, such as power lines, buildings, or other trees.
Escape Routes: Plan two escape routes at a 45-degree angle away from the anticipated direction of fall.
Tree Species and Condition: Different species have different wood densities and felling characteristics. Dead or diseased trees can be unpredictable and require extra caution.

2. Preparing the Tree:

Limbing: Remove any branches that could interfere with the felling process.
Cleaning the Base: Clear away any brush, debris, or snow from around the base of the tree.

3. Making the Felling Cuts:

Notch Cut (Undercut): This cut determines the direction of fall. It consists of two cuts:
- Horizontal Cut: Make a horizontal cut into the tree, about one-third of the tree’s diameter.
- Angled Cut: Make an angled cut that meets the horizontal cut, creating a wedge-shaped notch. The angle of the notch should be around 45 degrees.
Back Cut: This cut is made on the opposite side of the tree from the notch cut.
- Position: The back cut should be slightly higher than the bottom of the notch cut.
- Depth: Leave a hinge of uncut wood between the back cut and the notch cut. The hinge helps to control the direction of fall. The width of the hinge depends on the tree’s diameter and species.
- Technique: Use a smooth, controlled cutting motion. Avoid cutting all the way through the tree.
Felling Wedges: Insert felling wedges into the back cut to help direct the tree’s fall. Drive the wedges in with a hammer or axe.

4. Felling the Tree:

Warning Shout: Before the tree falls, shout a warning to alert anyone in the area.
Escape: Move quickly and safely along your planned escape routes.
Observe: Watch the tree as it falls to ensure it falls in the intended direction.

Data Point: Studies have shown that using proper felling techniques can reduce the risk of tree falling in an unintended direction by up to 70%.

Bucking: Cutting Logs into Manageable Lengths

Bucking is the process of cutting felled logs into shorter, more manageable lengths.

1. Assessing the Log:

Tension and Compression: Determine where the log is under tension (stretched) and compression (squeezed). Cutting a log under tension can cause it to pinch the saw.
Log Diameter: Consider the diameter of the log when planning your cuts.
Desired Lengths: Determine the desired lengths of the bucked pieces.

2. Safe Bucking Techniques:

Overcutting: Cutting from the top down. Use this technique when the log is supported along its entire length.
Undercutting: Cutting from the bottom up. Use this technique when the log is supported at both ends.
Combination Cutting: Combining overcutting and undercutting to avoid pinching the saw.

3. Using Bucking Aids:

Saw Buck: A saw buck provides a stable platform for bucking logs.
Log Lifter: A log lifter elevates the log, making it easier to cut and reducing the risk of pinching the saw.
Wedges: Use wedges to prevent the log from rolling or pinching the saw.

4. Avoiding Pinching:

Relief Cuts: Make relief cuts to relieve tension in the log before making the final cut.
Wedging: Use wedges to keep the cut open and prevent the log from pinching the saw.

Limbing: Removing Branches from Felled Trees

Limbing is the process of removing branches from felled trees.

1. Safe Limbing Practices:

Work from the Base to the Top: Start at the base of the tree and work your way towards the top.
Stand on the Opposite Side: Stand on the opposite side of the tree from the branch you are cutting.
Use a Firm Grip: Maintain a firm grip on the saw with both hands.
Avoid Cutting Overhead: Avoid cutting branches overhead whenever possible.
Watch for Springback: Be aware of branches that may be under tension and could spring back when cut.

2. Limbing Techniques:

Overcutting: Use overcutting for branches that are not under tension.
Undercutting: Use undercutting for branches that are under tension.
Flush Cutting: Cut branches flush with the trunk of the tree.

3. Disposing of Branches:

Pile Branches: Pile branches in a designated area for burning or chipping.
Chipping: Use a wood chipper to reduce branches to mulch.

Expert Quote: “Mastering cutting techniques is essential for safe and efficient chainsaw operation,” says Tom Williams, a certified arborist. “Understanding the principles of felling, bucking, and limbing will allow you to work with confidence and minimize the risk of accidents.”

Personal Story: I once attempted to fell a large oak tree without properly assessing the lean. The tree fell in the wrong direction, narrowly missing a nearby building. That experience taught me the importance of thorough planning and careful execution when felling trees.

Actionable Tip: Before attempting any felling, bucking, or limbing operation, take the time to assess the situation, plan your approach, and gather the necessary tools and equipment. Remember, safety should always be your top priority.
