Abstract
This study was conducted in clear cutting stands. For the whole-tree yarding operation, a tower-yarder based on excavator with a radio-controlled double clamp carriage was applied to analyze yarding productivity and cost. The productivity and cost of yarding operation was $6.2m^3/SMH$(machine utilization rate, 80.4%) and $13,705won/m^3$, respectively. Although the maximum yarding distance was longer than the previous studies, the setting up time of the tower-yarder was decreased as used straw line. The application of the radio-controlled double clamp carriage improved productivity and reduced costs. Based on the fuel log and growing stock($137.0m^3/ha$), the minimum production($m^3$) and area(ha) were $558.3m^3$ and 4.1 ha for Pinus rigida stands and $433.7m^3$ and 3.2 ha for Quercus mongolica stands, respectively. Based on the this study, it will be possible to select an efficient yarding machine by accumulation of data on minimum production and area for many machines in various harvesting sites.
