How do you get a ground rod to 6 feet ?

The soil in central Texas is called Caliche with a lot of clay, CaCO3 & shale. Attempting to drive in a ground rod yielded only a mushroom on top & blisters on me. Local tool rental place has concrete bits, but maximum length of 18 inches. Possibly longer bits are available in a larger city. Renting a back hoe is out. Any suggestions appreciated.

Nobody I ever heard of... but it sure works nice. Rick, I see on Hilti's web site he TE-76-ATC, and its accessories include a TE- Y driving shank and a series of adapters TP-TKS ground rod driving adapters for different diameters. Hilti BTW are suppliers of expensive quality tools to the construction industry, you probably won't find their tools in home handyman stores. The tool you rented is a little lighter than the one I used, and that is probably why driving times were a little longer. My Hitach PH-65 machine with home made driving adapter will drive a 16mm diameter 2.4m earth rod into dry clay in less than a minute. Pleased it worked for you. It is the way to go, isn't it! The numbers above might help people looking to rent a device.
