I rented one last Fall for exactly the same thing. It was a Hitachi as I
recall. Not a huge device. For my soil, mostly clay, it was easy - much
easier than I thought it would be. I think it took maybe 30 minutes to do a
dozen 5/8 inch 8 foot rods.
You might look at what the local rental yard might rent you as sort of a
guide. Don't forget the ground rod adapter.
I did also look at buying one but from recollection (possibly faulty) most
were in the $300-400 range except at Harbor Freight which was less than
$200. I opted to rent one at about $40 day (one day from mid-Saturday to
early Monday morning).

Subject: [TowerTalk] rotary or demo hammer for ground rods
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
