I also agree that you are better off renting or hiring out for your sump removal and going without the backhoe on the tractor and using those funds to go bigger or get implements that you will use to maintain the property.
I moved onto 2 acres with ~1.5 that needed clearing / landscaping. I chipped away at it for years with a 20 hp tractor that weighed ~4000 pounds with loader, brush cage filled tires and me. It was marginally heavy enough for landscaping with the bucket but did not have enough hydraulic power.
I later went to a 45 hp tractor that is ~6500 pounds but with ~3x the loader lift capacity and ~5x the curl force on the loader. This second tractor seems very appropriate for the landscaping and occasional tree removal / stump removal / rock removal that I do with it.
If you do have an occasional stump to remove, a 40-60 hp tractor with a set of heavy duty forks is actually a decent tool for ripping out trees and forks are useful for lots of other things and are not expensive. A stump bucket is also inexpensive and can dig footers, trenches, and also remove trees / stumps. I wouldn't remove an acre of woods this way but for the occasional stump after the main area is cleared these methods work fine. Below are some pictures of what you can do with forks and a stump bucket. I'm always using them and they aren't a lot of money.
I also appreciate the larger tractor in big snow storms. You can clear just about any snow with a 20 hp tractor with loader, but it may take a while. With the much better loader capacity on the larger tractor, I was able to put a huge bucket on the loader and it's night and day in deep snows. We recently had a 30+ inch storm and I did 9 driveways in the time my neighbors smaller tractor with loader did 1.
Check out all the brands near you in different size frames. Using JD for size reference only - you could get a lot done with anything form the 2000 series size to the 5000 series size. But the different size machines will do things at different rates and there will always be things that no matter what tractor you get, it just wont be big enough to handle it. That will happen a lot more with the 2000 series size than the 5000 series size. I'm not recommending a specific size. Just go out and test drive them. You'll get a feel for what is comfortable to operate - but don't buy that one. But the next bigger one (or even 2 sizes up). They shrink when you take them home and shrink again once they get a few hundred hours on them.
