I've been doing installs for about 2-1/2 yrs now and only about 12 jobs. I've always used a trencher. I have found that I spend a lot of time covering ditches and the yard looks like it went through surgery. What about the vaibratory plow? How can I get 5-6 runs of 1" sch20 pvc in one ditch with a plow? What do some of you more experienced guys find more user friendly and time saving?
