I don't hammer ground stakes very often, but every other time I hammer with a pipe nipple/cap and a hammer with a jack. What a workout! Not to mention broken joints. I used a Harbor Freight demo hammer, which to be honest isn't very heavy. But the HF hammer and this drive adapter got the job done quickly and with minimal fuss, and I had both bars flush with the slope in about 20 minutes. I wish I had known about this tool in years past!
