3 point ditch digger

Figured I would something like a straight shank ripper, then a guide for laying whatever I want, with wings and a roller to cover it up and roll it down. Might even use a coulter to cut the grass in front of the shank.

Anyone seen or built anything like this that may have some pointers?

I built one similar to what you're talking about for the back of my 2N.
I use it for loosening up the top soil so I can move it easier with the back blade.
It would work good for pulling a wire or tube like you need if you added a loop on the back of the foot.
The shank is a piece of scrap grader blade and the foot is a shur-nuff-real-mcCoy Caterpillar backhoe tooth. I can sink it down about 14"-16".
I would make a first pass without the pipe/wire attached to make sure you don't have any rocks etc in the way.
Have fun.
