I'm putting a water project in on the farm. It's got to be buried 2 ft deep. I'm going to rent a ditcher. One of my rental ditcher options will make the trench four and a half to five inches wid,e the other is six inches wide. How do I fill in the ditch after I've laid the pipe? With a shovel, or a hoe? So I just have to walk the whole mile and then step on top of it after I filled it? The ditch is through tall native grasses like little blue stem. Is this going to be a problem either for the ditcher or for refilling? I'm going to rent a ride on ditcher. Obviously I have no idea what I'm doing so any practical advice is welcome.
