Abstract: A cable pulling machine in which all of the operative mechanisms are mounted on a trailer for portability. The machine has an internal combustion engine driving a hydraulic pump supplying fluid pressure to a hydraulic motor on a winch spool which holds a length of line for pulling cable through a conduit. The trailer has, at its distal end, a pair of splayed legs allowing the trailer to be backed over-top of the job site conduit so as to position a boom mounted on the trailer to have the boom free end positioned over the conduit. The boom is adjustable for angle of incidence with respect to the ground for achieving a proper pulling angle. The ends of the splayed legs have adjustable jack rods for leveling the trailer.
