Not sure about drive efficiencies etc, but I handle a 50" Deere 450 tiller behind my 455 which is 22 engine HP. Now I am told this is also possibly over-rated compared to a CUT.
I have the tines about worn out, in my 7+ years of operating it, and I LOVE it. The only repair was the "hook" for the gate chain and the gate chain. Tilling in rocky or rooty soil has the tiller jumping all over the place and the chain stretched and the fork slot bent until it wouldn't hold the chain. I'd suggest being able to cover wheel tracks so that it cuts in nice. They don't run deep over packed, or moist soil, or when a lot of lofty organic matter is in place. I first cut my skid shoes narrow for gardens, but later took them off. It runs deeper this way. You may want to run a bead of hard face on the side boards if worried about wearing away.
When tilling, I find that I can go as fast as I want in most cases. If I go fast enough to load the engine hard, it's too fast for the tiller to do a nice job. We are in heavy nasty, bally clay here. When tilling sod, I sometimes get pushed around by the tiller trying to hold it back as it has a lot of thrust. The only time it REALLY works the engine is if I'm in super wet soil and start to get stuck. I drop the tiller for the thrust and floor the hydro. /forums/images/graemlins/shocked.gif
If you can rent or borrow one to try that would be my suggestion.
I'm pretty sure my 455 would handle a 55" unit so long as the little cat 0 3 point could lift it. For reference, the 47" 2 stage blower DOES ride the engine down hard...
Single pass can be done if soil is dry enough, but to get good results you'll need to go slow. Where you lift you will leave a hole. On the non overhang side you will not be deep so you may want to reverse the direction on the final pass. The non overhang side will leave a wheel track.
The tines will move soil somewhat towards the non overhang side. For this reason when I make my final pass across the end of a garden, I run the overhang to the outside. Without cleaning up in the non overhang side you will leave wheel tracks.
