A Running Skyline System for Harvesting Small Logs

A prototype skyline yarder, mounted on a John Deere JD 640* cable skidder, has been developed for harvesting small logs from thinnings. The objective was to advance technology through the development of a low cost, high performance system to solve major economic and environmental problems in managing young forests. Logging tests indicate that this type of system can make a significant contribution for solving these problems. Several manufacturers are currently engaged in developing yarders based on this concept.
