Hi, I'm Daniel Penselin, and this is how to dig fence postholes. The things you will need: gloves, a posthole digger and a water hose. First, spread the blades apart and plunge straight into the dirt driving as far as it goes. Wear glove for protection against blisters. Apply pressure by moving the two handles away from each other and lift the dirt caught between the clamshell blades and drop the load to the side, far enough away so it won't drop back into the hole. Rotate the blood in a circle and then repeat steps one and two. And now, you are ready to place your posts. And that is how to dig fence postholes.
