I made a tool to drive in ground rods. It's two parts. First is a 3 foot length of 1.5" pipe. The second is an axle from a 1 ton truck that fits nicely into the pipe. Once the ground rod is at a point where it's difficult to hammer down, I slide the pipe about a foot over the rod. Then I slide the axle down the pipe as hard as possible. What it does is act like a guided 16 pound sledge hammer. The pipe keeps the axle from sliding off. I've driven in a dozen or more rods with it. I think I've even broken some deeply buried rocks or forced them aside. It really works well.
