A method and means for pulling a length of fiber optic cable through an underground conduit is described wherein a lead puller is positioned at the exit of the conduit and one or more booster pullers are positioned at intermediate positions along the length of the conduit upstream from the exit thereof. The booster puller pulls the cable from the cable entry to the intermediate location and the cable is then fed downstream into the conduit with the lead puller being simultaneously operated to pull the conduit from the intermediate location to the exit. The lead and booster pullers each have a pair of hydraulically operated pinch wheels mounted thereon which may be selectively series connected or connected in parallel to achieve either maximum speed or maximum torque.
