Abstract

The efficiency of Timberjack C450 WHEELED SKIDDER was evaluated using cut-to-length method in Shafarood forests in Guilan province. In this study, the elemental times and effective factors on turn time were identified while 41 turns being studied. The effective factors included skidding distance: volume per turn, percent slope of SKID TRAIL, winching number of logs per turn. Tree species were recorded. Main results after data analyses can be summarized as follows:The MODEL OF SKIDDING TURN TIME as a dependent variable is a function of the independent variables skidding distance, volume per turn, winching distance, and the number of logs per turn. To production either with or without delays were 10.56 and 13.38 cubic meters per hour respectively. FAD model of machine cost was used being estimated at 290422 rails per hour. Based on this, the production cost with and without delay times were 32995 and 26653 rails per cubic meter respectively: Delay times count the most, next to times taken in either loaded or unloaded travel. The cost of sleidding per turn was linearly related to either of skidding or winching distances, as well as linearly related to increase in volume of log per travel turn.
