ABSTRACT:
An apparatus for installing cable underground is disclosed herein along with its method of operation. The apparatus utilizes a power driven land vehicle and a cable laying plow blade supported by and for movement with the vehicle in a way which places a bottom end portion of the blade in the ground so as to plow through the soil. A supply of cable is also supported on and movable with the vehicle along with a cable feed arrangement cooperating with the blade for laying a continuous length of the cable from its supply into the ground at a fixed depth relative to and along the path of the plow blade. The feed arrangement itself includes a feed shoe which makes it easy to bring up to ground level intermittent sections of the cable as the latter is installed and without withdrawing the plow blade. These spaced above ground cable sections serve as terminals for ready access to the buried cable.
