I've got 2.5 acres of residential property that I maintain with a
B7610. The work is mostly mowing and snow removal. The properties are heavily obstructed with trees and the lawns are a bit rough. Although I considered a BX at the time, I'm quite happy I went with the B. For the tree studded lawns, the B is almost too big; but it's done a fine job for 4 seasons now. For snow removal, it's almost too small...particularly when the covering to be removed is over a foot; still it gets the job done.
Since I've got larger Kubotas (see sig.), I've tried using them to remove heavy snowfalls. Their size and lack of HST make them quite inconvenient in my cramped quarters. I'm about as well off sticking with the
B7610 and putting up with its smaller bites and slower pace.
As to B-series tippiness, I haven't experienced it. Maybe it's because I have the rears filled (turf tires) or because The
B7610 does let you set the rear tires wider (not all Bs will). Still, mine are set at bucket width so it's not like they're way out there. I think it may be more a matter of experience. With many sidehill hours on high-wheeled Ag tractors, my tippiness alarm system is less sensitive than some.
I will say that the filled turf tires on the B give me amazing traction in snow. I expected serious problems and having to use chains. That's not been the case at all. The 7610 is quite agile in snow and gives up nothing but wheel diameter and ground clearance to my larger L and MX with R1s.
If your lawns are rough, you might appreciate the larger rear tires of a B-series. The smaller BX rears can give you a rough ride over the bumps. Having to slow down to keep from being bounced around may not be the best use of the tractor's capability. The
B7610 is fine on my rough lawns, but I didn't enjoy the jostling it gave me on an even rougher hayfield. The B's larger tire diameter and greater ground clearance also makes it less likely to become hung up in deep packed snow.

P.S. I'd get an old 4WD pickup with a blade to remove snow from that 1/4 mi. driveway. It'll be warmer and probably faster.
