What technique to do you to plow in your irrigation lines. Just starting my first (my house) and trying to get a plan together. Thought was to design, layout head placement with marking flags (visual reference), dig out heads, valve, "Ts", joints", etc... with a post hole digger. Then I would plow from hole to hole, make connections, etc.... done. What techniques do you use with the virbrating plow. Looking for thing to watch out for as well as time savings tricks. What about pulling wires, 2-3 pipes at once, cross-overs, etc....?
