It depends on your soil. At this QTH, I have had limited success using a 70
pound jack hammer. Make sure that you can buy a ground rod adaptor for the
hammer that you purchase.

Hi gang,
I am in the market for a rotary or demo hammer for remodeling work. I am
looking at tools that deliver 7-10# percussive force (10-14 joules).What is
the
size recommendation for a rotary or demo hammer for driving ground rods? I'm
sure that soil conditions play a large part but what is the minimum that
will
drive a ground rod in a timely manner? It would be nice to have a use for
the
tool once the work is done.
Tnx es 73,
Jim W5QM
