I should have been more descriptive about the tool I used, mine was a rotary
hammer drill by Hilti, with a special attachment. The attachment is easy to
find and usually the rental shop will have one. I was getting confused with
my UK description:)

Hi Howard,
I also have very hard compacted clay. I used an impact hammer with a
special attachment designed for ground rods. I borrowed mine, but you can
rent them cheaply. It took all of about five minutes each rod to drive
down.

My soil is very, very hard clay which makes it a perfect tower base... in
fact we had to jack hammer it out to build the base...
... Strong constructions workers hitting the top of the 8' ground rods with
Sledge Hammers they were able to drive 1 in about 4 feet and one about 5
feet... neither is deep enough....
Any suggestions on what mechanical or power tool to use to drive ground rods
further into the ground. Plus I want to put in a few more....
