@Darkmeep you do know that hardhats are for if it things FELL on you but, think about it, where does the dirt go that once filled that hole? ON THE GROUND, and what is used to move that dirt? and what is used to move the dirt? a
trencher which can potentially drop the dirt on somebody(whether it's a malfunction, human error or something), have you ever had a giant pile of dirt fell on you?
