Abstract
Abstract Hooking rules designed to increase average turn volume by limiting the minimum volume yarded per turn were tested with a small skyline cable yarder. The test was conducted on a steep-slope Appalachian hardwood site, harvesting fuelwood from logging residue. Average volume per turn yarded increased from 10.0 to 12.3 ft3, increasing yarder production from 121 to 156 ft3 per hour, and reducing yarding cost from $22.74 per hundred ft3 to $17.75 per hundred ft3. These results demonstrate the feasibility of applying a simple set of hooking rules to improve the efficiency of smallwood harvesting operations. North. J. Appl. For. 4:33-35, March 1987.
