A combimachine for harvesting of small sized trees; Pienpuun keraeilykaatoon perustuvan harvennuskoneen kehittaeminen

Abstract

The goal of the project was to develop a combimachine suitable for the harvesting of small sized trees in first thinning. The use of such a machine could considerably decrease harvesting costs in first thinning. The basic idea with the combimachine is, that the same machine both fells the trees and transports the timber to roadside storages. A forwarder was equipped with a lightweight felling device, which also can do the crosscutting and loading. When harvesting undelimbed timber the forwarder could be equipped with a load-compressing device. During the spring 1995 a trial was made with a combimachine in a first thinning stand of pine. An ordinary forwarder was equipped with the `Naarva-grapple` a device for felling, crosscutting and loading. The aim was to test how the felling device is working, to examine time expenditure for two different working methods and to collect data for the further development of the machine. The trial showed a need to add a delimbing feature to the Naarva-grapple. The need for delimbing is based on the fact, obtained during the trial, that productivity in transport of delimbed timber was over 30 % higher than in transport of undelimbed pieces.
