Abstract: There is disclosed an assemblage for laying an underground cable. This assemblage includes a movable but stationarily operated power plant, a digging tool and a cable laying tool. The digging tool and the cable laying tool are connected to the power plant so that they can be extended from the power plant to a selected distance and are then pulled back to the power plant. While being so pulled back the digging tool digs a trench and the cable laying tool feeds cable to be laid into the trench as the same is being formed. A brake is mounted on the cable laying tool and co-acts with the same so as to avoid slack in the cable while the same is being laid.
