2Similarly, when using a one-grip harvester to produce tree-lengths or delimbing in the. cycle time to travel to the tree, cut and delimb it, and cut the stem to length was about minutes per tree (range: shrubremover.bar to minutes).

Also, with inexperienced operators hang-ups, trees felled on top of the machine, broken components, etc.

This is consistent with similar sitesas reported by the operator where to trees are harvested per day. Several factors that may influence the productivity of the harvester include tree size, species (hardwood or softwood), branchiness andlor size of branches,Cited by: The cut-to-length method is a modern, nature-friendly logging method.

In the cut-to-length method, trees are harvested in the forest with equipment developed for the purpose, which makes the method effective and environmentally friendly.

The cut-to-length method is often thought of as a Nordic logging method. May 25, Harvesting systems. Shortwood (also known as cut-to-length): Trees are felled, delimbed, and bucked to individual product lengths directly in the stump area and then transported to the landing or roadside. Primary transportation is usually by a forwarder, although cable skidders are sometimes used. during the observation of seven wholetree and five cut-to-length operations.

All - operations were carried out in high density, small diameter wood stands common to Maine and this region. In addition to time, tree volume and residual stand damage data was collected.

Results of this study present a new model for feller-buncher harvesting. Apr 24, As the name of the method suggests, the trees are cut to lengths already in the terrain. The operator of the harvester, with some help from a computer, decides the lengths and he also decides which log goes where. (We wrote about this at shrubremover.bar a while ago in the kent county maryland tree removal permit Swedish Forestry #6).

He puts the different assortments in piles for the forwarder to pick up. Dec 02, The system under investigation was a classic CTL combination of a harvester and a forwarder: the former was tasked with felling, delimbing and cross-cutting the trees into m logs, with length tolerance ± m, and a minimum small-end diameter of 7 cm over bark; the latter would separately haul the logs and the logging residues to the roadside landing shrubremover.bar by: 1.

Block width was 15 m or 5 tree rows, which was considered the best work frontage for the harvester. Therefore, block length was 20 trees or 40 m, resulting in m2block surface area. In the proposed conguration, the harvester had ecient access to all trees in ve rows in front of the shrubremover.bar by: 1.
