I realize that this thread has gone a bit cold but thought I'd add to it in case someone else comes along.
The topography matters a LOT, as does the general condition of the ground.
I've currently got a Kubota B7800 that has been used WAY past what I'm sure it was intended to do (I push myself very hard, anything that I use needs to be able to keep up with me!). 40 acres which were/are mostly brush and trees, lots of wet ground with smatterings of HUGE ruts from logging skidders (almost 2' deep), but otherwise pretty level. I've nearly high-sided my tractor in the ruts: the wort ones have been painstakingly box-bladed down (small tractor = a lot of time/work). While this tractor does have HP, it's light. Wasn't until about a year ago that I had ballast put in the rears. I'd usually be stringing along a field mower or the box blade: the later is heck-for-stout and is great ballast. I can lift a fair amount of weight in the loader (with good ballast), but, going over smooth, dry ground is one thing, going over wet and uneven ground (I recently made the mistake of trying to cross a small ditch with the loader maxed out and I missed hitting it at an angle and dropped both front wheels in and that was that!). Bigger tractor means bigger wheels and more stability. If people were nuts like me then maybe they can get away with smaller tractors, but if you're sane then a bigger tractor is your better bet. Go at least 40 hp.
I'm now in the market for something in the 50hp range. It's a tough decision. What isn't tough to decide, however, is whether I keep my B7800. It stays with me until the day I die:

So, 35hp could be enough, until it isn't. And when that point happens you start risking safety. Generally one will always find limits. The idea is to not bump into them with any real regularity. For those rare cases in which more power is required then just go out and rent it (or hire it out). Bigger machines = bigger operational costs; and when you get them stuck (last summer I stuck an 9k lb excavator in a place where my tractor has safely been in- go figure, more GP with the tractor than that tracked rig, so not really sure what went wrong here- I was able to get it out with a manual cable puller and my truck; I later rented an 18k lb excavator and I made sure that I didn't get close to ANY soft ground as there wouldn't have been any way that I'd have been able to get it out!).
35 -40HP is enough if you buy a hevy underpowered tractor Like a L39 Kubota, some Kioti's, or certain Mahindras, but what your getting is a heavy tractor with a small motor.
If you do field work, get some HP with the size.
