We have about 8 acres, mostly swamp, but mow about 2-3 acres of hilly grassy areas with groups and single trees interspersed (not at all a golf course style lawn) and our dealer talked me up out of the BX and down out out a bigger B, so we got the
B2320.
It isn't a zero turn by any means, but even with a 60" MMM and our grassy areas being fragmented by groups of trees, it gets into some pretty tight spaces and is quite nimble on the slopes too.
We never feel like we're going to roll it over. Especially with loaded tires and a well weighted ballast box.
If it was only about what it could lift, pull, or dig, I'd want a bigger tractor, but for the compromise of mowing and moving stuff-brush, logs and fallen trees, rocks, gravel, dirt, and more things than you (or I) could think of in advance, I would get the
B2320 again.
It really is in kind of a sweet spot for the mix of enough lift, pull and push capacity, maneuverability, mowing quality, fuel economy, and features.
It's even going to lift my AC unit up to my 2nd-ish story window this weekend to get ready for summer- did I mention what a back, and other of my worn out old body parts it has/is saving from failure?
For your size property, I'd go with the B for the ground clearance and weight. My first tractor, I went to the dealer for a BX. He convinced me to get the
B7500 for just those two reasons and I only had 2 acres. I now have 66 acres and an
L5240 but couldn't do without the B. As far a stability, I set the rear wheels all the way out and it has never given me reason to pucker.
