We get trucks for lots of projects but they won’t sit around and wait on us to position 200 fence posts. The only good thing is we have a mixer for the skid steer that will handle 16 bags at once.

Mixin concrete in a wheelbarrow aint so bad! Especially for fence posts. You just need a good supply of water near by. It gets a little tiring when you set something bigger like antenna towers and you mix about 45 bags at time and as fast as you can.
WoW!! Your mixer will hold 16 bags. I have a stand alone mixer that will hold 4 bags and it's a real PITA if you don't have a helper. Helper either tips the mixer or holds on to the wheelbarrow.

To set fence posts, we put the mix in dry. Pack it down to keep the post straight and come back after a week. If in the dry part of summer, we will pour water in the hole. I have had post last 15 + years set in concrete.
