Rent a skid steer with a front post hole digger. Your issues will go away.
A three point digger is for sandy loam and loose soils. I've built many miles of fence in red clay.

I'm with you now, I didn't realize this was a mechanical/three point. Like Dennis said, a skid steer will give the down pressure needed. How many holes have to be dug? Oops I see you said 30-40

Look and see if the cutting edge is on the bottom side of the bit. It is normally that way so it does not grab in normal soil. On harder holes like clay it is better some times to have the cutting edge ground from the top and at a sharper angle. That way is almost feeds its own cut ( for lack of a better description). If you modify your bit then It can wear out pretty quick so the last one I did I made the cutting tip out of 1/2 bar and welded it on.

Yeah the local Great Plains has a hydraulic QA mounted digger I can rent for $75/day. I'll just need to get hoses and couplers to run from my rear remote to the loader.

Hmmm so maybe flip the teeth over?

We have ours set up so we can stick a tpost in the back and have it sticking horizontal straight out the back and one person hang off of it or sit on it when it gets low enough. We have to do this with almost every hole we dig.
