Yeah... When I was doing house solar (big ground mount 15.9kW system), I really beat the hell out of myself trying to finish with a rental jackhammer in a day.

Yeah... When I was doing house solar (big ground mount 15.9kW system), I really beat the hell out of myself trying to finish with a rental jackhammer in a day. I was drilling the holes and the auger was bouncing off the hardpan, so I rented a jackhammer... and it was an electric beast, not a light pneumatic version. Anyway, I got it done in a day of pounding, but I was not in good shape the next few days. Having low stress of getting it done is nice. Also, depending on the area you live and the community you're part of, that sort of thing may just go into the general rotation of "Oh, yeah, I've got one of those." I'm borrowing someone's portable cement mixer right now for deck footings, a friend up north has my auger, I've got his subsoiler... in rural areas, useful tools tend to just wander around, and as long as people have a vague sense of where they might be, it's not a big deal.
