Shooter,,, I have the BX 2360 same as the 70 just a couple years older,, get a push blade while your at it,, that will save you tons of time plowing snow too, Also the BX platform is very maneuverable while you cant do a some of things a B series will I have been very impressed with mine. If you recall the big snow we had about 5 years ago, that old gal pushed snow that was 3 feet deep along my ridge and never grunted. The 60inche deck is pretty tuff to beat, mine goes through black berry and wild rose and just keeps coming back for more, slow and easy is the key. I mow about 5 acres.
Just MHO for what your going to do ya might want to take a hard look at the BX platforms
