A ground rod installation device and method as shown for pressing ground rods into the earth using hydraulic drilling equipment. The device has a plunger mechanism attachable to a Kelly Bar of the hydraulic drilling equipment utilizing a removable pin, a first cylindrical telescoping member through which the plunger is slidably attached, and a second telescoping member through which the first telescoping member is slidably attached. The ground rod is inserted into the fully extended telescoping members, placed above the desired location and driven into the ground without pre-drilling, pre-placing holes and in one substantially continuous drive stroke.
