Arrangement for harvesting timber

摘要

An arrangement for harvesting trees consisting of a portable articulated grapple suspension and an independent cutting and delimbing unit comprising a main frame resting on the ground and a tree-engaging frame pivotally mounted to said main frame. The portable suspension is attached to a motor vehicle and employed to cut down trees and transport them to the independent cutting and delimbing unit. The portable suspension is moved to position the tree in contact with the tree-engaging frame, which pivots on the main frame to align itself with the tree. Thereafter, trimming arms and guide rollers of the tree-engaging frame engage the tree, while the tree is pulled through said frame by the motor vehicle, to delimb the tree. If desired, a cutting saw on the tree-engaging frame may be actuated to cut the tree into one or more sections.
