Don't know about a trencher Nuru, but a lot of folks are using a sub-soiler as a cable plough. Depending on your voltage/codes you may be able to do this fairly cheaply. Sub-soilers are inexpensive (<$100) and you can weld a "J" tube on the back side to feed the cable through. Of course you will be limited on depth so I wouldn't use this for 110V but for cable, phone or low voltage lighting it should work just fine. At least that's my plan /w3tcompact/icons/smile.gif
