8" Wide ???
How many pipes were you laying in that trench?
Now I'm only a homeowner with the only experience I've got is installing my own irrigation system. I can tell you that I was able to dig at a rate of about 10' per hour when I only had to dig 12" deep, 4" wide. That time does not include removing the sod, laying pipe, or backfilling. It was in rocky clay soil, but the soil was moist (going was MUCH slower during the dry season).
In several places, I hand trenched. I was doing such a terible job at restoring sod that I just decided to hack it
