Makita's ground rod attachment was $20 at a local mom-and-pop hardware
store. Lowe's didn't carry it, but the people working there at least knew
enough about what I wanted to send me to the right place.
It sinks 8' rods into hard clay with plenty of rocks with almost no
mushroom-heading. If you encounter a house-sized boulder (plenty of those
around here!) you're in trouble, but I guess you would be no matter what.
Rental places gave me a puzzled look when I asked about ground rod
attachments. My plan was to by the attachment myself and rent the hammer
drill. But, I ended up just buying both. The Makita unit is quite capable
for this purpose and was under $600 new.
