Preparing for the Task: Safety First!

Before you even think about picking up a chainsaw, the most crucial step is safety. Working with fallen trees, especially large ones, carries significant risks. Understanding these risks and taking appropriate measures can prevent serious injury.

Assessing the Fallen Tree

Take a moment to survey the fallen tree. Its position, the surrounding environment, and the tree’s condition all play a role in how you’ll approach the cutting process.

Stability: Is the tree resting on other branches, rocks, or uneven ground? A tree that’s under tension can spring back violently when cut, a phenomenon known as kickback.
Lean: Does the tree have a natural lean? This will influence the direction it falls further if it’s disturbed, and can create stress points.
Obstacles: Are there power lines, buildings, fences, or other valuable items in the vicinity? Never attempt to cut a tree that is leaning towards or touching power lines. Contact your utility company immediately.
Rot or Decay: Is the wood rotten or infested with insects? This can make the wood brittle and unpredictable.

Essential Safety Gear (ppe)

This is non-negotiable. Personal Protective Equipment (PPE) is your first line of defense.

Safety Helmet: Protects against falling branches and debris.
Eye Protection: Safety glasses or a face shield to prevent sawdust and wood chips from entering your eyes.
Hearing Protection: Earplugs or earmuffs to guard against the loud noise of a chainsaw.
Chainsaw Gloves: Provide a better grip and some protection against minor cuts.
Chainsaw Trousers/Chaps: Made with special fibers that can stop a moving chain, preventing severe leg injuries.
Steel-Toed Boots: Protect your feet from falling logs and sharp objects.

Choosing the Right Tools

The right tools make the job safer and more efficient. For cutting up a fallen tree, a chainsaw is usually the primary tool.

Chainsaw Selection and Maintenance

If you don’t own a chainsaw, consider renting one. If you do, ensure it’s: (See Also: How to Clean a Cat Tree From Fleas: A Complete Guide)

Appropriate Size: For most fallen trees, a chainsaw with a bar length of 16-20 inches is suitable. Larger trees might require a more powerful saw with a longer bar.
Sharp Chain: A dull chain is dangerous. It requires more force, increases fatigue, and can lead to kickback. Learn how to sharpen your chain or have it done professionally.
Properly Tensioned Chain: The chain should be snug but still able to be pulled by hand with gloves on.
Full of Fuel and Bar Oil: Ensure your saw is adequately lubricated and fueled before you start.

Other Useful Tools

Felling Wedge(s): Plastic or aluminum wedges used to control the direction of a cut and prevent the saw from binding.
Axe or Hatchet: Useful for clearing smaller branches or splitting smaller pieces of wood.
Cant Hook or Peavey: For rolling or moving logs.
First-Aid Kit: Always have one readily accessible.
Gloves for Handling Wood: Thicker work gloves to protect your hands from splinters.

The Cutting Process: Step-by-Step

Once you’re geared up and have assessed the situation, it’s time to start cutting. The key is to work methodically and be aware of the forces at play within the wood.

Understanding Wood Tension

Fallen trees are rarely just lying passively. Gravity and the way the tree has landed create tension and compression zones within the wood. Cutting incorrectly can release this tension suddenly and dangerously.

Compression Zone: This is where the wood is squashed. It’s usually on the underside of a bent log or where the log is resting on an obstruction. Cutting into a compression zone from the top can cause the wood to pinch the saw blade.
Tension Zone: This is where the wood is stretched. It’s usually on the top side of a bent log. Cutting into a tension zone from the bottom can cause the wood to spring apart, potentially trapping the saw or causing kickback.

The Basic Cutting Technique: Bucking

The process of cutting a felled tree into smaller sections is called bucking.

Clear the Work Area: Remove any debris, rocks, or brush from around the log you intend to cut. Ensure you have a stable footing.
Identify Stress Points: Look at how the log is supported. Are there any obvious bends or areas where the log is under pressure?
Make Your First Cut (The “Relief Cut”):
- If the log is supported at both ends and sagging in the middle: Cut 1/3 of the way through from the top (compression side). This is your scoring cut or blaze cut.
- If the log is supported in the middle and sagging at the ends: Cut 1/3 of the way through from the bottom (tension side). This is your undercut.
This initial cut relieves some of the internal pressure.
Make the Second Cut (The “Through Cut”):
- If you made a top cut first, now make a cut from the bottom, meeting the first cut.
- If you made a bottom cut first, now make a cut from the top, meeting the first cut.
The goal is to cut through the log without pinching the saw.
Use Felling Wedges: If you’re worried about the saw binding, or if the log is particularly large or under significant stress, insert a felling wedge into the cut as soon as there’s enough space. This will help keep the cut open.
Cut in Sections: Work your way along the log, cutting it into manageable lengths. For firewood, 16-20 inch lengths are common.

Advanced Bucking Techniques for Specific Situations

Sometimes, a fallen tree presents more complex challenges than a simple sag.

Situation 1: Log Supported at One End

If the log is resting on the ground at one end and elevated at the other:

From the elevated end, make a top cut about 1/3 of the way through.
Then, make a bottom cut that meets the top cut.
As you cut, insert wedges into the top cut to prevent pinching.

Situation 2: Log Supported at Both Ends

This is the classic sagging log scenario: (See Also: Grow a Mediterranean Gem: How to Care for an Olive Tree…)

Start by making a top cut on the underside of the sag, about 1/3 of the way through.
Then, make a bottom cut from the top side, meeting the first cut.
Use wedges generously in the top cut to keep it from closing.

Situation 3: Log Resting on Obstructions

If the log is resting on rocks, stumps, or other logs:

Identify the obstruction and where the log is being compressed.
Start by making a top cut about 1/3 of the way through, just past the obstruction.
Then, make a bottom cut that meets the top cut.
It’s often best to cut the log into sections before the obstruction, then cut the section with the obstruction.
Do not cut directly into the obstruction itself.

Situation 4: Large Diameter Logs

For very large logs, you might need to:

Make a top cut about 1/3 of the way through.
Make a bottom cut, but stop about 2-3 inches short of meeting the top cut. This creates a hinge.
Insert wedges into the top cut and drive them in to prevent the saw from binding.
Complete the cut from the top, or carefully make the final cut from the bottom if safe.

Limbing the Fallen Tree

Once the main trunk is bucked into sections, you’ll need to remove the branches (limbing).

Work from the base to the top of the trunk.
Cut branches on the “away” side of the trunk whenever possible. This prevents the saw from getting trapped if the branch is under tension against the ground.
Be aware of branches resting on the ground or other objects. These will be under compression and can pinch your saw. Cut them from the top first, then from the bottom if needed.
Use a “pulling” motion with the saw, rather than pushing.
Keep your body balanced and avoid overreaching.

Dealing with Difficult Wood

Some wood types or conditions require extra care.

Rotten or Punky Wood

Rotten wood is often soft and can crumble. It’s also unpredictable.

Use a sharp chain and be prepared for the wood to break apart unexpectedly.
Avoid cutting too deeply into severely rotten sections in one go.
Be extra cautious with kickback, as rotten wood can snap.

Green Wood vs. Dry Wood

Green wood is heavier and can be more prone to pinching. Dry, seasoned wood is lighter but can be harder. (See Also: Master Vertical Ribbon: How to Put Ribbon on a Christmas…)

Knots and Burls

Knots can be incredibly hard and may cause your chain to deflect. Be prepared for this and maintain a firm grip.

Moving the Cut Sections

Once you have your manageable pieces, you’ll need to move them. This can be as challenging as the cutting itself.

Use a cant hook or peavey for rolling logs.
Consider a log arch or skid if you have many sections to move.
For smaller pieces, a wheelbarrow or garden cart can be helpful.
Never try to lift logs that are too heavy on your own. Get help!

Post-Cutting Tasks

You’ve done the hard part! Now, what to do with the wood?

Firewood: If you plan to use it for firewood, allow it to season (dry out) for at least 6-12 months, depending on the wood type and climate. Stack it properly to allow for air circulation.
Mulch: Smaller branches and bark can be chipped to create mulch for your garden.
Composting: Wood chips and smaller pieces can be added to your compost pile.
Disposal: If you can’t use the wood, check with your local waste management for disposal options, such as chipping services or designated drop-off sites.

Chainsaw Maintenance After Use

Don’t forget to clean and maintain your chainsaw after a big job.

Clean the air filter.
Check and clean the chain brake.
Inspect the chain and bar for wear or damage.
Sharpen the chain if necessary.
Store the chainsaw properly according to the manufacturer’s instructions.

Learning and Improving

Every fallen tree is a learning experience. Pay attention to what worked well and what didn’t. If you’re unsure about a particular situation, it’s always better to err on the side of caution or seek advice from experienced loggers or arborists. Proper chainsaw safety courses are also highly recommended for anyone who plans to use a chainsaw regularly.
