8" is a guess of the top of my head. I had a few narrow shovels, and a few regular ones. The most pipes I had to lay was 4 of 1"poly, so 4" may of worked. But if I factor in sod removal and re-filling the trench, your 10 feet an hour MAY be 6 feet an hour net. Therefore, I am not to surprised at the 4 feet an hour I got from 2 uninspired workers that also had to dig around some tree roots by hand. ( long story there, involving a demanding homeowner )
I happy with my numbers now.
