ABSTRACT:
An underground cable installing apparatus is disclosed herein along with its method of operation. The apparatus utilizes a power driven land vehicle and an elongated cable laying plow blade supported by and for movement with the vehicle in a way which places a lowermost end portion of the blade in the ground with its cutting edge disposed in the direction of vehicular movement. As the blade moves through the ground it lays cable in its path from a cooperating cable feeding mechanism. In accordance with one operational feature of the apparatus provided herein, its plow blade is supported for movement relative to its vehicle between a number of different operating positions including positions in front of and behind the vehicle as well as various positions on either side thereof. In accordance with another feature, the cable itself is fed from a supply wound about a drum or reel which is supported in an adjustable fashion on the vehicle.
