    Description

    This paper documents the results of a study to determine the cost and productivity of two tree-bucking and product-sorting methods used by West Virginia loggers harvesting three to four types of roundwood products. The methods include manual chainsaw bucking and bucking with a hydraulically powered chainsaw slasher. Results show that chain saw bucking of trees averaging 53ft³ produced 2,155ft³/productive hour. This compares to 1,109 ft³/productive hour for mechanized bucking of trees averaging 33 ft³. Utilization levels below 50 percent for each method indicate that both were capable of greater production with increased felling and skidding production, and that added product sorting would not limit system output or increase harvesting cost Results also include regression equations for estimating bucking and sorting time per skidder turn as a function of turn and tree attributes. The results should be useful to logging planners and managers considering multiproduct harvests.
