ABSTRACT:
The present invention is directed to a method and apparatus for installing a utility conveyance. A tractor which includes sensors, a plow locator and a monitor system is presented. The sensors are used to locate demarcation points, which identify the boundaries of a right way or a preexisting utility conveyance. The plow locator is used to determine the location of a plow relative to a preexisting utility conveyance. Sensing information produced by the sensors and plow location information produced by the plow locator are communicated to the monitor system. A visual representation of the demarcation points and the position of the plow relative to the demarcation points is displayed on a screen associated with the monitor system. As such, a tractor operator may navigate an engineered path and install a utility conveyance.
