You’re standing in the backyard looking up at a dead oak. It’s leaning. Maybe it’s dropping limbs on your shed every time the wind picks up. Your first instinct is to grab the chainsaw and start hacking away, but honestly, that is exactly how people end up in the emergency room. Or worse. Cutting down a tree—felling, if we’re being technical—is a high-stakes physics experiment. If you don't respect the weight of the wood, the wood won't respect you.
I’ve seen DIYers think they can just "notch it" and hope for the best. It doesn't work that way. A medium-sized tree can weigh several tons. When that much mass starts moving, it doesn't care about your plans or where your truck is parked.
Before we even talk about the blade hitting the bark, you have to understand the How to cut down trees basics that professionals live by. It isn't just about the saw. It’s about the lean, the wind, the species of the tree, and having a literal escape plan for when things go sideways. Because they do. Often.
Assessing the lean and the "Dead Man" limbs
The first thing you do isn't starting the engine. You walk around the tree. Look up. Is the crown heavier on one side? Trees rarely grow perfectly straight, even if they look like it from the kitchen window. If a tree leans ten degrees to the north, you are going to have a massive fight trying to make it fall south. Gravity is a relentless jerk.
You also need to look for "widowmakers." These are dead branches hanging loosely in the upper canopy. The vibration of your chainsaw is often enough to shake them loose. They call them widowmakers for a reason; they come down fast and silent. If you see huge, dead limbs dangling 40 feet up, you might want to put the saw down and call a certified arborist. Seriously. It’s not worth a cracked skull.

Check the trunk for rot. If you see mushrooms growing out of the side or big holes where woodpeckers have been partying, the internal structure is compromised. A rotten tree is unpredictable. You might start your back cut and have the whole thing "chair-back" or split vertically, which is a nightmare scenario called a barber chair.
The Gear: More than just a sharp chain
You need a chainsaw that actually fits the job. Trying to take down a 24-inch diameter trunk with a little 14-inch electric saw is a recipe for a bind. You’ll get stuck. Then you’ll have a stuck saw and a half-cut tree, which is a structural disaster waiting for a breeze.
- Chaps are non-negotiable. Chain-saw chaps are made of ballistic fibers (like Kevlar) designed to clog the sprocket and stop the chain instantly if you slip.
- Eye and ear protection. You need to hear the tree "talk." Wood makes a specific cracking sound right before it goes. If your ears are ringing from the engine, you might miss the signal to run.
- Felling wedges. These are plastic wedges you hammer into the cut to keep the tree from sitting back on your bar. They are cheap. Buy four.
The Notch: Precision matters more than power
When you're ready to learn how to cut down trees, the notch is your steering wheel. This is the chunk of wood you remove from the side of the tree facing the direction you want it to fall.
The most common mistake? Making the notch too shallow. You want that notch to go about one-fourth to one-third of the way through the trunk.
There are different styles, but the "Open-Face" notch is generally the safest for beginners. You make a top cut downward at about a 70-degree angle, and then a bottom cut that is perfectly horizontal. This creates a wide "mouth." The beauty of the open face is that the tree stays attached to the stump longer as it falls, giving you more control until it’s almost on the ground.
Don't just hack a triangle out. Use the sights on your chainsaw—most pro saws have a line on the casing—to aim exactly where you want the tree to land. If you aim for the gap between the garden and the fence, make sure that line is pointing right at it.

The Hinge: The only thing keeping you safe
This is the part everyone messes up. You do NOT cut all the way through the tree. If you do, the tree becomes a loose cannon. It can slide off the stump, kick back, or spin in mid-air.
You need a hinge.
The hinge is a strip of uncut wood—usually about an inch thick—between your notch and your back cut. Think of it like a door hinge. It guides the tree down. As you perform your back cut (which should be level with or slightly above the corner of your notch), you must stop before you hit the notch.
If you cut through the hinge, you lose all steering. The tree will go wherever the wind or the lean takes it.
Why the "Barber Chair" is terrifying
Imagine a tree that is leaning heavily. As you start your back cut, the internal tension is so high that the tree splits vertically before you finish. The back half of the tree kicks straight back at head height while the top falls forward. It happens in milliseconds. To avoid this on leaning trees, pros use a "bore cut" where they stab the saw through the middle of the trunk and cut toward the back, leaving a "trigger" of wood to be cut last. It’s an advanced move. If you aren't comfortable with it, don't touch a leaning tree.
The Escape Route: Know where you're going
Before the first chip of wood flies, clear two escape paths. They should be at 45-degree angles away from the back of the tree. Never just walk straight back. Trees can kick off the stump and fly backward.
When that tree starts to moan—and it will make a distinct "crack-crack-pop" sound—finish your cut, pull the saw out, set the chain brake, and walk away. Don't stand there and watch it fall like you're in a movie. Look up as you walk to make sure no limbs are falling on you from behind.
Actionable Steps for a Successful Felling
If you are going to do this yourself, stop and follow these specific steps. No shortcuts.
- Clear the base. Remove all brush, rocks, and trip hazards within a six-foot radius of the trunk. You need clean footing.
- Sound the wood. Hit the trunk with an axe. A hollow "thud" means rot. A sharp "ring" means solid wood. Rot means you should probably call a pro.
- Check the wind. If the wind is gusty or blowing opposite your intended fall direction, go back inside and watch TV. Do not fight the wind.
- Set your wedges. Once your back cut is deep enough, drive a wedge in. This ensures that even if the tree leans back, it won't pin your saw.
- The "Look Up" Rule. Every time you stop the saw, look up. Things change. Branches shift.
Honestly, the best advice on how to cut down trees is knowing when you're out of your league. If the tree is within 1.5 times its height of a power line, a house, or a neighbor's property, the DIY savings aren't worth the insurance claim. Organizations like the International Society of Arboriculture (ISA) have directories of people who have the rigging gear to take trees down in pieces. Sometimes, the best way to cut down a tree is to write a check to someone who has the right insurance.
If you do go for it, keep your chain sharp. A dull chain makes you push harder, which makes you tired, and tired people make mistakes. Cut slow, think fast, and always have an exit.
Next Steps:
- Inventory your safety gear: Ensure you have chaps, a helmet with a face shield, and sturdy boots.
- Measure the height: Use the "stick trick" (holding a stick at arm's length to estimate fall distance) to ensure your drop zone is actually clear.
- Check local ordinances: Some municipalities require permits even for trees on private property, especially if they are certain species or sizes.
