Contoured Cable Roller Abstract A log skidder has a fairlead with a main guide roller having a special contoured surface to prevent grooving of the surface of the guide roller, to prolong cable life, and to assist in evenly winding the cable on a winch drum. The special contoured surface of the guide roller includes a pair of shaped or rounded shoulders at the side extremes which are aligned with the side rollers in a way that a cable passing over the main guide roller in contact with one of the side rollers receives a downward and inward centering force component which moves the cable toward the midportion of the main guide roller.
