Felling of trees is among the most typical jobs carried out during logging and arboricultural operations. It is a hard and potentially hazardous operation that requires the sawyer (chainsaw operator) to know trees, be fit, and be trained in tree felling operations.
The most typical technique used in felling a tree is a multi-step process that initially involves the creation of an open-faced notch in the trunk. In appropriately executed cuts, the production of the notch positions the fixed load of the tree such that the sawyer, through making use of the back cut and the staying hinge, can reliably manage the direction the tree will fall. However, mistakes made during felling can result in property damage or major injury/death to the feller or spectators.
Safe felling operations start with correct inspection of the tree and of the conditions in an area 2.0 times the height of the tree to ensure it is devoid of individuals & residential or commercial property. The next step utilized in felling a tree is making three exact and tactical cuts. The graphic listed below illustrates a “conventional” notch, however other notch designs are used depending upon the situations of the cut. Sawyers should make informed decisions relating to the style of notch, in addition to the depth of each cut to securely and reliably fell trees.
These cuts must be done by a sawyer who has actually been trained and wears the suitable personal protective equipment like gloves, eye defense, hearing security, head security with face shield, chainsaw chaps, and steel-toed boots. The chainsaw selected for felling trees need to be the appropriate size (bar length) for cutting the subject tree and needs to be sharp and in good repair work. Having the proper equipment like tree felling wedges, taglines, and other tree felling gear may help in the effective and safe felling of trees.
The initial step in felling a tree is for the sawyer to look for a straight tree and has an equal size diameter that is free of bulges or irregular architecture. If the tree is leaning or has a slight lean the sawyer must utilize a level or a plumb line to figure out how much lean and what instructions it leans. The sawyer must prepare the felling operation in the direction of the tree’s existing lean. Trees with structural flaws are possibly dangerous candidates for felling. Trees with spiraling of the bark indicate spiraling of the interior wood grains, which might make it tough to manage the direction of the fall. Trees with dead branches or pockets of rotten wood are also difficult to fell by standard notch and drop operations. The sawyer needs to examine the base of the tree. If the base is hollow or one side of the tree has rotten wood, it might not be a suitable choice for felling operations because the rotten wood will impact the instructions that the tree falls.
If the course of the tree’s designated fall is clear of obstacles and targets, the next step is for the tree sawyer to determine. No persons or valued targets should be in the path of a tree being felled for a range of a minimum of 2.0 times the height of the tree from the subject tree’s base (see Drop Zone image).

The tree sawyer ought to make sure there are no obstacles like buildings, trees or other physical barriers that will block his/her to escape if the tree begins to fail without warning throughout the cutting operation. The tree sawyer ought to constantly presume that the tree will fall in EVERY possible instructions and take step to guarantee absolutely nothing can be damaged regardless of which method the tree falls.
A single error made throughout a tree felling operation can result in damage to home or serious injury or death to the tree feller or bystander. The safe felling of a tree consists of proper tree and website evaluation and conformance with relevant standards for work cutting and placing.
