I would have to agree with Tomd999's recommendation. For what you have in mind you will be kicking the snot out of a SCUT. The SCUT will be able to do alot of what you want, it's just when you get to the heavier digging, landscaping & moving / lifting of heavy large rocks.
Note that although you can dig to a certain depth with a FEL (approx 6" to 12") it's not very effective. Would need a backhoe to do any serious digging. To do any serious landscaping, digging etc, you need a heavier tractor.
I am currently using a 35HP tractor that weighs in close to 4,000 lbs when I include my counterweight on the back. The tractor performs beautifully for loader work & plowing. However, I am also right in the middle of a Project of moving large rocks for landscaping. Anywhere from 500 lbs to 6,000 lbs. Well, the capacity of the FEL is no where near what I need for this. So I ended up getting forks for the 3PH. Even here, after I subtract the weight of the forks I can only lift 1,600 lbs. The rock is sandstone so your getting quite a bit of rock for the weight. When you start looking at other rock (especially granite) your only looking at anywhere from 50 to 70% of the rock size for the same weight. So depending upon what kind of rock you have on your property, you may be surprised how heavy it is.
As the big three are priced much higher & generally have less lift capacity & weight, I would strongly consider a Kioti or Mahindra which offer much beefier tractors for the same size & have better lift capacity. The MT265B you were first looking at actually would do you very nicely. You know what they always say, go with your first instincts.
Buying power is always (normally) an issue & granted, implements are more bucks for larger size tractors. But if you go with a little more tractor now, & buy some of the other implements down the road I think you will obviously have a much more capable tractor & be happier in the long run.
Good Luck,
Vic
