Stop in for a cup of coffee

When I did the hops field I rented a bobcat with a drill on it best thing ever! Bet they rent out cheaper than that will though.......
I knew a guy that brought his over and did most of the post hole for my deck
was cheap 125 for the day and fuel, punched 50 or so holes and about a food down it is all shale/rocks no way I was doing 4' for each pole by hand.
I still had to hand dig for the ones by the house. 4 ft... had to be same depth as foundation.
We did some fencing for ostriches years back. Auger went down 18” and stopped. Pulled it up and look in hole, its like a shiny ceramic bowl. The clay around here can be miserable. Throw in a cup of water and 15 minutes later good to go another foot.
This time of year is best, the clay is still pretty wet.
Same deal here with clay. Didn't stop the auger, but looks like a clay pot when you get 12 to 18 in.
