Equip rental companies, at least in Virginia, rent impact hammers and the
fitting for Grd Rods. I have gone this route on two occasions and drove 36 8ft
rods each time. Its less expensive than buying a hammer that you probably won't
use very often, but it will also accomplish the job and let you test a
particular brand befor you buy.
Good luck,
