I plan on buying a tiller sometime before next spring. I have a Kubota L3800, 38 engine hp and 30 PTO hp. Any opinions about whether I should get a 72" or 60"? The rear wheels now measure 60" outside to outside, but in two weeks I will be installing 4"spacers on each rear wheel. Another question I have is about the working depth of the tiller. My initial brief research shows that some have a working depth of 8", some less. Any opinions on that point? It seems to me that the working depth would another factor, along with width, in determining the hp requirement. And more working depth seems better to me.
For your future tractor configuration, and considering your present HP, I'd focus on the 72" models. Working depth has a lot to do with soil type and condition. Also, If I want to go much deeper than 5 inches I have to rearrange how the 3 point linkages are pinned, just to allow the implement to drop that much. Pay attention to the resulting PTO shaft angle if you do this. Too much angle is not good for the joints when you're putting all that torque through them and throwing in the occaisional shock load from roots, rocks, submerged engine blocks, and whatever else the eye can't see.
