Tree harvester (Click for video) 6-wheeled Valmet harvester Small 4-wheeled Rottne harvester Timberjack harvester John Deere harvester in SwedenA harvester is a type of heavy forestry vehicle employed in cut-to-length logging operations for felling, delimbing and bucking trees.
When a suitable place to buck the tree is located the cut is made. Significant value may be lost by sub-optimal bucking. [5] Local market conditions will determine the particular length of cut. It is common for log buyers to issue purchase orders for the length, diameter, grade, and species that they will accept.
The remaining part of the tree's diameter is for the back cut, which weakens the tree structurally enough for it to fall without splintering and other unwanted effects. There are three types of directional felling notches that are most commonly used in the logging and arboriculture industries by chainsaw operators.
Cut-to-length logging (CTL) is a mechanized harvesting system in which trees are delimbed and cut to length directly at the stump. [1] CTL is typically a two-man, two-machine operation with a harvester felling, delimbing, and bucking trees and a forwarder transporting the logs from the felling to a landing area close to a road accessible by ...
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. [4] 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. [4]
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with shelterwood and seed tree harvests , it is used by foresters to create certain types of forest ecosystems and to promote select species [ 1 ] that require an abundance of sunlight or grow in ...
