Hi Gary,
I used this method a few years back and found that it worked very
quickly.
They call that a female thread adapter, but the hose barb is a male.
One of our new school graduates must have written the description as in
the past it simply would have been called a male hose adapter.

If you use an appropriately sized female garden hose repair coupler,
such as
http://www.homedepot.com/p/Ray-Padula-Metal-5-8-in-Garden-Hose-Female-Thread-Repair-with-Stainless-Steel-Clamps-RP-RIFR-6/205167514
and pound it into a piece of appropriately sized EMT, you'll have the
all that you need. I (lightly) held the EMT in a vice and inserted
the nipple end of the coupler into the EMT. I inserted a ratchet
socket into the female hose end of the coupler and used a hammer to
tap the back of the socket so as to drive the nipple end into the EMT.
To install the ground rod, you simply turn on the water supply and
start driving the 10' stick of EMT into the soil till you reach the
desired depth. Turn off the water supply, remove the EMT and drop
your ground rod. Once I had the rods at the desired depth, I once
again used water to back fill some of the soil that was pushed up out
of the hole by the water. Since I'm in central Florida & the soil is
pretty sandy, I found that refilling the hole around the ground rod
works pretty well as there's a lot of resistance by the ground rod to
being pulled back out by hand after back filling.
I just took a picture of a 1/2" ground rod sitting along side a 10'
piece of 1/2" EMT with the female repair coupler attached and I placed
it on my web site at http://www.w4abc.com/hydrogroundrod.html

I used to live in NE Illinois and in southern Louisiana and that's
exactly how I did my long grounding rods. No stones at all to run
into. Here in Connecticut it took a lot of effort to find exact
placement for my HI-Z Rx array, the soil is one big rock with a thin
surface layer dirt on top. Get a few inches down & hit solid.
