I think you mean one of these. It is has a long handle and a circular head. It is as heavy as a sledge hammer and is swung much like one. Take pretty much the same energy output as using a sledge hammer. https://permies.com/t/118383/a/83616/thumb-Earthship-hammer.JPG
Or you can do the job with a pneumatic backfill hammer. But that requires a large compressor to provide the air to drive it. Of course you then need a big generator to power the compressor. Here is a video of how that tool is used. The person who created the video and is building the house said he spent 2K to buy the tools needed to pack the tires this way.https://www.youtube.com/watch?v=y8LwovQ4DCk
I vote for this power tool other than it would further destroy my body. It is a young mans job to pack tires, they have the strength, stamina and can take that kind of physical abuse to their joints....for a while.
