Abstract
A method of pulling electrical cable through an underground tubular conduit includes providing a backhoe with a boom and positioning the backhoe outside of the electrical housing building. The operator mounts a pulley to the end of the boom and inserts the boom into an open portal. The operator mounts a take-up reel to the backhoe and reeves the pull line through the pulley and around the take-up drum. Rotating the backhoe wheel will pull the electrical cable secured to the pull line through the conduit. The take-up drum utilizes inner and outer support flanges and drum bolts for extending through holes provided in the backhoe wheel.
