Two lumberjacks at work on a tree on the Atherton Tableland, Queensland, Australia, 1890–1900A completed undercut in aSugar Pine tree in Madera County, California around 1911.[1]
Felling is the process of cutting down trees,[2] an element of the task oflogging. The person cutting the trees is alumberjack. Afeller buncher is a machine capable of felling a single large tree or grouping and felling several small ones simultaneously.[2]
In hand felling, anaxe,saw, orchainsaw is used to fell a tree, followed up bylimbing andbucking in traditional applications. In the modern commercial logging industry, felling is typically followed by limbing andskidding.
Afeller-buncher is a motorized vehicle with an attachment which rapidly cuts and gathers several trees in the process of felling them.
Incut-to-length logging aharvester performs the tasks of a feller-buncher, additionally doing the delimbing and bucking. When harvesting wood from a felled tree, the recommended methods should be followed in order to maximize wood recovery. The suggested trend is to make deeper cuts and smaller openness when performing undercuts.[further explanation needed][3]
Theundercut ornotch cut is the guiding or aiming slot for the tree and is a V-shaped notch placed on the side of the tree in the direction of intended fall.[4]
Theback cut orfelling cut is made on the opposite side of the tree of the undercut and is cut through the base of the tree severing the “hinge” holding the tree up.[4]
The Tongue and Groove cut is a type of cut that uses the tree as its own guide for where it will fall. This is commonly used by loggers when they need precision in their drop
This was an experiment conducted regarding felling trees and the continuous felling of trees in boom-corridors which might lead to an increase in harvester productivity. An efficient way to do this would be to use felling heads which would increase efficiency and fall time.[6]
