Abstract

Tree cutting is the most important component that affects all stages of harvesting. Tree cutting is included felling, cross-cutting (bucking), delimbing and topping. This study was carried out in the northern forests of Iran (i.e. Hyrcanian Forests) near the Caspian Sea in the Neka Chob Company, in order to evaluate subsections of tree felling. The main goals of this study are time study of tree felling, estimating and measuring productivity and costs of chainsaw as well as identifying regression model of tree felling time. Multivariate Regression of felling time was a function of tree diameter, distance among felling trees and air temperature. Hourly production of chainsaw felling was 44.61 m3/h (8 trees per hour). There was found a negative relationship between tree diameter and the Tree felling cost of production unit, so that when the tree diameter was increased the cost of Tree felling was being decreasing exponentially.
