DOWNLOAD EBOOK →Production rates, skidding costs, and soil disturbance were compared for two partial-cut units-one with preplanned skid trails and winching and one conventional unit-harvested with a Caterpillar D-7F. For the unit with preplanned skid trails and winching, production was 11 percent less, and skidding cost per unit volume was 29 percent more than for the conventionally harvested unit. However, only 4 percent of its area was in skid trails, compared to 22 percent of the conventionally harvested unit. Total cycle time with winching was a function of skidding distance, skid trail slope, number of logs per turn, volume per turn, number of winching cycles, and the average winching distance.
