I've got four new service upgrades to do in the next two weeks. The ground is frozen. Any good ideas on driving the ground rod past the freeze point?

You better be either a really good shot with a sledge hammer or use a simple fence post driver.

When I was in business, I had an electric demolition hammer to drive the ground rods into the soil. If the ground was frozen, we would use a hammer drill to get through the frost line, then drive the rod down. Here in northern NJ the frost can get as deep as 36". We had some long hammer drill bits.

everybody knows this is the best time of year for driving ground rods! the frozen ground is good for keeping the rods from going in TOO FAR!...lol!....

seriously, we have a driving attachment for our hilti that works pretty good....also, i've used an auger bit and extension before, then pour a little antifreeze, or even warm "water", down the hole...............

To all that use their roto hammers or demolition hammers to drive ground rods, do like gramps says and use an attachment. Driving the rod directly in your tool may not ever cause a problem, but, when it does, (I know from experience) it cost to repair the head.

lighthouse, mate,welcome to ECN.
What a huge idea that is, best I've heard yet,what sort of tip do you use for this?.
How prevalent is the Hilti in the US?, they are pretty big over here(NZ), for the serious contractors, we have Core-bits and all sorts of other attachments, but none to drive an Earth Rod.
Was the Hilti, an American invention?, just curious?, one thing I must say I'm glad that someone invented it.
It makes life so easy.
