In known rocky areas I have found that you should drive them in on an
angle. It gives them a chance to deflect. I found driving them into
soil filled with river rocks to be much easier when slanted.

I found that really difficult to drive rods would tend to bend when
hit really hard with a sledge so... I cut a couple lengths of tubing,
one about a foot and the other a couple feet. They are sized to let
the rod go inside easily, a tight fit is not required. With one of
these over the ground rod where it would bend it doesn't bend and it
keeps the force of the blows aligned with driving the rod, keeping it
"in column" and not being wasted flexing or bending the rod.
I have also used an electric "demo" (demolition) hammer with a rod
driving bit and with patience could drive rods where hammering was
nearly impossible. I climb up a ladder to balance the electric demo
hammer on the rod. I don't have to support the hammer just balance it
and experiment with applying down force or just letting the hammer's
weight do the job. Sometimes one works better than the other.

effective. The clay and sandstone here is terrible. More than likely
the one that I borrowed wasn't big enough - although it was pretty
darn substantial.

Go rent a hammer drill and purchase a ground rod adapter for installing
ground rods.
Makes quick work of installing an 8' ground rod.
I had 5 ground rods installed in less than 30 minutes. We have clay and
cliche here in the Amarillo panhandle.

I live in Kansas in an area that has some of the worst clay that I have
ever had to deal with.
It's sticky gooey terrible stuff, sticks to everything like epoxy!
Trying to drive eight-foot ground rods's in the ground is near
impossible,
I think the stickiness just builds to a point where it's near
impossible
even using a 10 pound sledge.
So my question is would several 4 foot rods placed approximately 4 feet
apart be satisfactory?
Thanks for your thoughts and inputs.

Jeff
