Rick,
In my case I used a sledge hammer and a large break bar. i screwed the anchor
in as far as possible, hit it with the sledge and turned it again. I proceeded
that way until the anchor was in deep enough. Each anchor took about 15 minutes
(manual labor).

I have a 50' Roan 25G tilt over tower that I installed using 8" MILSPEC
Anchors. http://milspecanchors.com . Pull out resistance is 9,000 pounds in
hard pan soil. They will drive through or around granite and sandstone rocks
which are common in northern Arkansas. Using an electric jack hammer took
less than 2 minutes to drive each anchor. You can use the same tool to
drive your ground rods while you are at it.

Thanks for posting that website. Lots of stuff to choose from.
Could you point us to the actual "8" MILSPEC" part you used?
You mention using a jack hammer to drive it. Are you referring
to the arrow head type? AKA "duck bill". As opposed to screw in; I
don't know how you use a jackhammer to install a screw in type.
BTW, please, make and model of jackhammer and bit used.
Here we have not just hard pan, but cemented hard pan, however
zero rocks.
