WOW talk about a loaded question,, Its easy spending other peoples money,, so lets start
A BX with a 60 inch deck r4 tires and a push blade will go maybe 14 k
A B with uses a lot of the same drive components with the same set up maybe 18k, if you go for a cab model the price jumps to like 20k, and the sky is the limit
So to try and answer your question allow me to expound from my experiences with the BX. I mow 5+ acres push snow and keep the drive way in good shape, tow, push and do things one would not think this little tractor should/can do. I don't know what else you plan to do but cutting on steep banks along a pond or creek is not a good idea no matter what brand of tractor you use. I/we have a non descript 48 inch tiller and the BX2360 does a grand job,,, Now another thing do you have lots trees with over hanging limbs the new ROPS I think are like 7 foot high and the next larger size have taller ROPS though they will fold down for storage, NOT WHILE RUNNING,,
Im sure guys with the B model will chime in but which ever you choose go to the dealer drive it around ask him to bring one over to try out and see if it will do what your wanting to do.
And remember pictures when you get your new beasty we loves tractor porn
