Hand felling

In hand felling, an

axe An axe ( sometimes ax in American English; see spelling differences) is an implement that has been used for millennia to shape, split and cut wood, to harvest timber, as a weapon, and as a ceremonial or heraldic symbol. The axe has ma ...

saw A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and mov ...

chainsaw A chainsaw (or chain saw) is a portable gasoline-, electric-, or battery-powered saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. It is used in activities such as tree felling, limbing, bucking, pru ...

limbing Limbing or delimbing is the process of removing branches from a standing or fallen tree trunk. In logging, limbing follows felling. Limbing plays a role in fire prevention by removing branches from live trees that can otherwise serve as part of ...

in traditional applications. In the modern commercial logging industry, felling is typically followed by limbing and skidding.

Feller buncher

A feller-buncher is a motorized vehicle with an attachment which rapidly cuts and gathers several trees in the process of felling them. In

cut-to-length logging Cut-to-length logging (CTL) is a mechanized harvesting system in which trees are delimbed and ''cut to length'' directly at the stump. CTL is typically a two-man, two-machine operation with a harvester felling, delimbing, and bucking trees and ...

a harvester 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.

Types of cut

The ''undercut'' or ''notch 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. The ''back cut'' or ''felling 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.

Boom-corridor experiment

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.
