Abstract

Tree cutting is the most important component that affects all stages of harvesting. Tree cutting is included felling, cross-cutting, delimbing and topping. This study was carried out in the northern forests of Iran (Hyrcanian Forests) near the Caspian Sea in the Neka Chob Company, in order to evaluate subsections of tree bucking. The main goals of this study were time study of tree bucking, estimating and measuring productivity and costs of chainsaw as well as identifying regression model of tree bucking time. Multivariate Regression of bucking time was a function of tree diameter and tree length. Hourly production of chainsaw bucking was16.88m3/h (4 trees per hour). There was found a negative relationship between tree diameter and tree bucking cost per production unit, so that when the tree diameter was increased the cost of tree bucking was being decreasing exponentially.
