Tractor Options? Float pos. on hydraulics and MFWD

Number one is running our twin hay merger. Minimum HP requirement for it is 100 HP but we pull alot of hills and want something that could handle a triple-pickup merger if need be--HP requirement for that is 130 HP
THE TRACTOR MUST HAVE HYDRAULICS THAT HAVE A 'FLOAT' POSITION! Our Case 1370 doesn't, the 4840 does. The 4840 is a bit oversized for what we're using it for.

Running a round baler.

Light Tillage--Disking with a 12' or so disk.

And some other additional, smaller stuff (TMR perhaps)

What I was wondering is, can we get into something that would fill these roles, has MFWD, and won't constantly be breaking down, for under $30,000 or is that just wishful thinking?

My uncle is running a 5250 Case IH that is turned up to 130-150 HP and that seems to be something that we could do as well, and keep the cost down, but I was wondering if that much power going through a 115 HP tractor from the factory will just tear the heck out of the transmission and PTO. Does anyone have experience with this? We won't be doing any heavy pulling with it, and no heavy PTO work to speak of, but will these tractors take that kind of HP without killing themselves?

Also, I was looking at the Case 2294 and 2096. Do either of these tractors have the Float position on the hydraulics? Is the motor on the 2294 Case, while the 2096 is the 5.9 Cummins? How is the fuel efficiency of these motors? How would they compare to a new tractor, as far as fuel efficiency?

Thanks guys!
