I am having the same project starting about Tuesday of next week. Going to bury PVC pipe for irrigating flower beds in our front yard. I intend to use my subsoiler to dig a trench. Then turn it around and mount it on the tractor with the point angled the wrong way. Kinda like trying to push it thru the ground in reverse. I have a piece of angle iron I intend to mount to the subsoiler that will keep the pipe from slipping off to the side. Wife driving very slow and me feeding the pipe. Hopefully it will work. All I have to do is get the pipe half a foot or so below ground level as there will be cutoffs to drain the water at low points and I will use a compressor to blow it out in the fall.
Wish me luck and keep this thread up so we will know how each other's projects come out.
