Abstract
  • This project was one of several studies conducted during the summer of 1981 that were part of the Smallwood Harvesting Research Program administered through the Department of Forest Engineering, Oregon State University. The study looked·at the feasibility of falling and yarding whole trees as a combined activity in a cable thinning operation. This approach was compared with conventional thinning where the two activities occur as seperate and distinct operations. Field trials utilizing both methods served as the basis for evaluation. These trials were conducted in a young growth stand of Douglas-fir located on the Paul Dunn forest some 12 miles northwest of Corvallis, Oregon. The crew used in the felling and yarding activities consisted of forest engineering students working for the school forest. They had been logging with a Koller K-300 yarder throughout the summer. This was the same machine that was used for yarding in this project. The hot-yarding technique involves the use of a swing operation to remove trees from the landing. A John Deere 440 rubber tired skidder with an experienced operator was employed for this. The regular crew performed all other felling and yarding operations. A 11 settings in this study required the use of one intermediate support for the skyline. A Koller, one ton capacity, self clamping carriage was utilized in the yarding operations.
