Driving Ground Rod with a Bottle of Water
Here is one that most people don't know about. It works as long as you don't hit any rock.
Get a bottle of water. Take your ground rod and jab it into the ground a few inches. Pour a little water in the hole. Insert rod and start working it up and down. The water will lube it up and it will start going down. You can do it with one hand. When it starts getting tight, pull out and add water, go again. Repeat and driven.
You can do it with less than 16 oz of water in the right clay type soil. I've done it a bunch of times with smooth ground rounds, never tried rebar, the ribs might make it a little tougher, but I bet it still works.
I've won bets on this one several times. :thumbup:
