I built a cable layer with a long sweep elbow of 2 inch metal conduit strapped to the back of a subsoiler. Pulled it with my Ford 2000. Buried lots of direct burial UF cable. Would easily handle putting in irrigation pipe. Might not have enough traction with a cub cadet unless your soil was very soft, so you might want to rent a 4wd sub compact or larger tractor with a cat 0 or 1 hitch.
