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 ...
Length measurement also can be used for automated cutting of the tree into predefined lengths. Computer software can predict the volume of each stem based on analysing stems harvested previously. This information when used in conjunction with price lists for each specific log specification enables the optimisation of log recovery from the stem.
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 ...
A tool that allows quality assessments of single trees or plots. Log grades to be specified and value specified by user. Output can be saved and printed. Able to estimate wood volume and log grades in a single tree, a plot of trees or the whole forest. The tool displays information graphically and has import and export data function.
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
The unit cost of the feller buncher is primary affected by the tree size and the tree volume. [10] The unit felling cost is lower when the tree size increased. For example, tree with 5 inches at DBH has the unit cost of $70 while tree with 15 inches at DBH has the unit cost of $12. As the cost of feller buncher is high, only large tree volume ...

A forwarder is a forestry vehicle that carries big felled logs cut by a harvester from the stump to a roadside landing for later acquisition. Forwarders can use rubber tires or tracks. [ 1 ] Unlike a skidder , a forwarder carries logs clear of the ground, which can reduce soil impacts but tends to limit the size of the logs it can move. [ 2 ]
