Description: Continuous time and motion study techniques were used to develop productivity and cost estimators for the skidding component of ground-based logging systems, operating on steep terrain using preplanned skid roads. Comparisons of productivity and costs were analyzed for an overland random access skidding method, verses a skidding method utilizing a network of preplanned designated bladed skid roads. Productivity levels decreased while costs increased as the amount of winch line cable needed to be pulled to choke logs increased. Although estimated skidding costs were higher when the designated skid roads were used, the increased costs may be offset by a reduction in adverse stand and site impacts, and a reduction in the safety hazards often associated with ground-based skidding on steep terrain.

Keywords: Ground-based harvesting, harvesting costs, productivity
