Chuck,
I went through this about a number of years ago. Here' we have a lot of
shale about 4 feet down. I typically use a sledge hammer to get the rods
in. Once, I rented a Bosch electric jack hammer (60 lbs as I recall) and
ground rod driver. Most of them still wouldn't penetrate the rock. So, I
cut them off at ground level with a hack saw, and just put more in the
ground.
