Has anyone ever seen anything like a post hole digger with a different attachment that can be used for tilling amendments into 200 gallon above ground pots?
/ 3 point or skid steer post hole digger/mixer for large pot tilling?
Why not gently tip the posts over on soft ground, using the tractor FEL, mix in the amendments with the FEL, tip the pots back up with the FEL and refill with amended soil?
Or you could use nylon slings suspended from the bucket to tip and refill the pots.
In either case the mix would be more thorough.

I’m pretty sure it would just spin the pot around. If they are fabric and you held them in place somehow (which would be very dangerous doing by hand) they would probably rip apart.
