Tree Cutting and Felling: How the Cuts Actually Work
A tree does not fall where you want it by luck. It falls where the cuts send it. This guide explains the notch cut, the back cut, and the hinge, so you understand what a professional crew is doing and why direction control matters so much on mountain ground.
The notch cut sets the direction
Felling starts with a notch cut on the side the tree should fall toward. The cutter removes a wedge of wood, usually about one fifth to one quarter of the trunk's diameter deep. The open face of that notch aims the fall like a gunsight.
There are three common notch styles:
- Open-face notch. A wide mouth of 70 degrees or more. It keeps the hinge working almost until the tree is on the ground, which gives the most control. Most modern training teaches this cut.
- Conventional notch. A 45-degree mouth with a flat bottom cut. Faster to make, still accurate, but the hinge breaks earlier in the fall.
- Humboldt notch. The angled cut comes from below, so the wedge is taken out of the stump instead of the log. Loggers favor it on slopes because it saves trunk wood and helps the tree jump clear of the stump.
The back cut releases the tree
The back cut comes in from the opposite side, an inch or two above the bottom of the notch. It does not meet the notch. The cutter stops early on purpose, leaving a strip of uncut wood between the two cuts.
The hinge is the whole trick
That strip of uncut wood is the hinge. About a tenth of the trunk's diameter, it bends as the tree goes over and steers the fall into the notch's aim, the same way a door swings on its hinges. Cut the hinge too thin and the tree can twist or set back. Cut through it and the tree is free to fall in any direction, including at the cutter.
Why this is not a weekend project: a leaning trunk, hidden rot, wind, or tension in the wood can override a perfect notch. Professionals read the lean, use wedges and ropes, plan two escape routes, and know when a tree must come down in pieces instead of one cut. On the steep, tight lots common around Asheville and the Western North Carolina mountains, most trees near a house are climbed and dismantled section by section, not felled at all.
When felling is the wrong tool
Whole-tree felling needs a clear landing zone longer than the tree. In a yard with a house, lines, a road, or a neighbor's fence inside that zone, a crew removes the tree from the top down instead. See our tree removal guide for how that works and what it costs.
Hiring for cutting work in the Asheville area
Ask any crew how they plan to control the direction of the fall, and whether they carry liability insurance. A good outfit answers both without hesitation. In Asheville, Burnsville, and the surrounding mountains, we recommend Restoration Treeworks — insured, local, free estimates: (828) 989-7766.
