Presented is an underground cable laying apparatus that leaves virtually no visible scar in the turf under which cable, wire, line, hose, etc. is laid. The apparatus utilizes a pair of angularly displaced turf slicing wheels to slice and separate the turf forming a slit into which cable may be laid.

Presented is an underground cable laying apparatus that leaves virtually no visible scar in the turf under which cable, wire, line, hose, etc. is laid. The apparatus utilizes a pair of angularly displaced turf slicing wheels to slice and separate the turf forming a slit into which cable may be laid. A cable guide tube and roller properly place the cable within the slit. A pair of turf closure wheels close the slit in close proximity to the release point of the cable to ensure proper placement of the cable. The slit in the turf is gently and completely closed over the cable, leaving virtually no visible scar within the turf to upset the aesthetic beauty of a lawn. Further, the configuration and rolling action of the turf slicing wheels ensures that other underground cables will not be damaged if inadvertently encountered.

What is claimed is: 1. An underground cable laying apparatus, comprising: a mounting yoke; a pair of angularly displaced turf slicing wheels rotatably coupled to the mounting yoke, the turf slicing wheels defining a forward contact area therebetween; a cable guide tube positioned aft of the forward contact area of the turf slicing wheels, the cable guide tube having a cable inlet and a cable outlet; and a cable feed guide mechanism positioned in proximity to the cable outlet, aft of the cable guide tube, wherein the cable feed guide mechanism is a guide wheel having a groove around an outer periphery thereof sized to accommodate the cable to be laid. 2. The underground cable laying apparatus of claim 1, further comprising a feed tube support extension member coupled to the cable guide tube in proximity to the cable outlet. 3. The underground cable laying apparatus of claim 1, further comprising a cable guide coupled to the cable guide tube and displaced from the cable inlet to aid in guiding cable into the cable inlet. 4. The underground cable laying apparatus of claim 1, wherein the cable guide tube is curved from the cable inlet to the cable outlet. 5. The underground cable laying apparatus of claim 1, further comprising a guide wheel cleaning mechanism operably connected to the guide wheel to remove foreign debris therefrom. 6. The underground cable laying apparatus of claim 5, wherein the guide wheel cleaning mechanism comprises a groove cleaning rod positioned within the groove of the guide wheel. 7. The underground cable laying apparatus of claim 6, wherein the guide wheel cleaning mechanism further comprises wheel edge scrapers positioned along either side of the guide wheel. 8. The underground cable laying apparatus of claim 1, wherein the mounting yoke includes at least one mounting receptacle. 9. The apparatus of claim 1, further comprising a turf closure assembly operably coupled to the mounting yoke and positioned relative to the pair of turf slicing wheels to close the slit in the turf opened thereby aft of the cable outlet. 10. The apparatus of claim 9, wherein the turf closure assembly comprises a pair of turf closing wheels angularly positioned relative to one another and laterally displaced from one another a distance greater than a lateral spacing at a trailing edge of the pair of turf slicing wheels. 11. An apparatus for laying cable under turf without leaving a visibly obvious scar in the turf, comprising: a mounting yoke having at least one mounting receptacle defined therein; a pair of turf slicing wheels rotatably mounted on the mounting yoke, the turf slicing wheels being positioned in a diverging relationship to one another and defining a forward contact area therebetween for opening a slit in the turf when the pair of turf slicing wheels is pulled therethrough; a cable feed tube positioned between the pair of turf slicing wheels and terminating in a cable outlet positioned to guide the cable into the slit opened by the pair of turf slicing wheels; and a cable feed guide mechanism positioned aft of and vertically downward of the cable outlet relative to a surface of the turf to position the cable within the slit in the turf and to protect an outer surface of the cable from scraping, wherein the cable feed guide mechanism is a guide wheel having a groove around an outer periphery thereof sized to accommodate the cable to be laid. 12. An underground cable laying apparatus, comprising: a mounting yoke; a pair of angularly displaced turf slicing wheels rotatably coupled to the mounting yoke, the turf slicing wheels defining a forward contact area therebetween, and being angularly displaced relative to one another along both a horizontal and a vertical axis of the mounting yoke; a cable guide tube positioned aft of the forward contact area of the turf slicing wheels, the cable guide tube having a cable inlet and a cable outlet; a turf closure housing pivotally coupled relative to the mounting yoke; a pair of angularly positioned turf closing wheels rotatably coupled to the turf closure housing; and a pair of closure assembly mounting arms fixably coupled to the mounting yoke; wherein the turf closure housing is pivotally coupled to the closure assembly mounting arms, and the turf closure housing includes at least one positioning member adapted to contact at least one of the closure assembly mounting arms to limit pivotal travel of the turf closure housing in at least one direction. 13. The underground cable laying apparatus of claim 12, further comprising a turf follower spring coupled between the mounting yoke and the turf closure housing. 14. The underground cable laying apparatus of claim 13, further comprising a spring tension nut positioned to vary a bias force supplied by the turf follower spring.
