The soil in central Texas is called Caliche with a lot of clay,

Local tool rental place has concrete bits, but maximum

a larger city.
Renting a back hoe is out.
Any suggestions appreciated.

I have a Glen Martin ground rod driver (fashioned after a fence post
driver) that worked fine in Houston. In San Antonio, it only drives a
rod about one foot down, then muck... I ended up just driving a short
rod, mainly used as a connection post, and then I extended several
long, buried wires out from it.
