"... it takes a lot of HP to pull." My experience on a heavy clay soil is that it takes a number of passes to break things up. The clay resists penetration better than a prededominately sand soil. The disk in clay is initially cutting into the top few inches of soil (less resistance). On sand the disk will easily cut down and penetrate farther meaning you're moving more soil and encountering more resistance moving that soil. Clay will powder and flow around the disk like water.
I'm using a similar disk (Leinbaugh) made out of tube steel. To be fair, I haven't used the disk behind my 30 hp L3710 Kubota. I've always used the 60 hp Ford 5600.
I suspect part of the answer is how fast you want to get the penetration. if you do it in a number of passes you can get by with less hp. If you want to do it with fewer passes, you'll need more hp.
