ABSTRACT:
A log skidder has a pair of upper and lower rollers mounted rearwardly of a towing winch to receive a cable therefrom. In normal operation, the cable is solely guided over the upper roller whereas during the ascent of a steep grade, for example, the cable is further received under the lower roller to substantially decrease the tipping moment arm imposed on the log skidder.
