I put in a 3/4" poly water line using a similar set up. I have a L2501 with loaded r4s. Never slipped or strained. Did the entire 200' at idle. They key is that you are not pulling the entire length of pipe through the "trench", you are cutting, and laying it in as you go. I think if you put 3" LONG radius elbow on the subsoiler, it would work nice. The size of the pipe has no bearing on how hard the tractor is pulling. Very key to not have a rocky rooted path. When you find a root, you have to pick up on the sub soiler to cut it. Rocks are another story. Another interesting note, I had no problem making turns(within reason). The feeder pipe can swivel off the back to help with this. The pipe on mine is a 2" regular radius electrical rigid 90. The hardest part is feeding the pipe. I threw my loader all the way up with the coil on the forks, and it uncoiled itself into the ground as I went. The TSC Chinese crap I bought is fine for the occasional job, but Rhino and others make a much better unit at a much higher price. As a side note, I own a brand new BH77 that I love using, but chose this option as it is much less invasive. After you lay the pipe, run over the earth zipper to zip it back together..real clean finish on sod, fast, and effective. Only down side is depth, can probably only get it down 24" on average.
