Now he had the means to develop other ideas in logging machines. [12][10] There was a research suggested that productivity has a significant positive relationship with the tree size which means the larger stem size, larger tree height or larger diameter at breast height (DBH) results in a high productivity of the feller buncher. It runs parallel to the Andes Mountains, extending from Morro de Arica in the north to Taitao Peninsula, where it ends at the Chile Triple Junction, in the south. However, they cannot handle wet or loose soil, or slopes above 25%. The plane of the saw is transverse to the axis of the vertical support.
