What is the best way to dig the trenches, by hand or a with a machine?
The easiest way to dig trenches is with a machine, but you can put the system in a section at a time by hand if you like exercise and you have a strong back. Even if you use a machine, you will need to dig some of the trench ends and tight places by hand. You will dig most of the backflow hole by hand, and will occasionally trim off corners and remove rocks the trencher couldn’t dig out.
