Today my wife and I buried almost 2000' of wire for our underground dog fence using something I cobbled together out of a cheap Amazon subsoiler, some conduit, and a few hose clamps. Worked like a champ The dog fence company quoted me $2200. The first photo is stopping to splice the wire after the first 1000' roll ran out.

I sharpened the leading edge of the subsoiler and it cut through some pretty hefty roots without a problem but if I had to do it again I'd buy a better quality subsoiler that mounted directly to the 3 point quick hitch instead of having the intermediary Chinese receiver. The receiver mount isn't made to take the kind of forces involved in cutting roots and I had to stop midway through and straighten it out on the hydraulic press and re-weld it.
