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 ...
Cut-to-length logging is the process of felling, delimbing, bucking, and sorting (pulpwood, sawlog, etc.) at the stump area, leaving limbs and tops in the forest. Mechanical harvesters fell the tree, delimb, and buck it, and place the resulting logs in bunks to be brought to the landing by a skidder or forwarder. This method is routinely ...
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.

Timberjack is a manufacturer of forestry machinery for both cut-to-length and whole tree logging, and was a subsidiary of John Deere from 2000 to 2006. History
Limbing can happen at the stump in log/tree length systems and cut-to-length systems or at the landing in whole-tree logging. Chainsaw limbing. When the tree is lying on the ground, branches may be storing enormous potential energy through mechanical strain. When a branch is cut, often with a chain saw, this energy can be released suddenly and ...
Trunks which are cut down for making lumber are generally called logs; if they are cut to a specific length, called bolts. The term "log" is informally used in English to describe any felled trunk not rooted in the ground, whose roots are detached. A stump is the part of a trunk remaining in the ground after the tree has been felled, or the ...
