Given the limited information I'm hearing:
- I want to mow, ~60 inch deck
- I want a snowblower, probably front mount
- I want to put it in my garage
- I'm upgrading from a Husqvarna
Therefore, I say BX2380 or B2601. LX is likely bigger than you need, they're really sized for a 72 inch deck. You're putting it in the garage so you can't have a cab.
Get the BX if you're mostly mowing and snowplowing, and not much else. Get the B if you want to run the loader a bit and have some rough territory you want to drive it in, or do driveway maintenance. They're about the same length/width, the B is quite a bit taller with bigger wheels and more ground clearance. If you want something that's a bit bigger than a ride-on, the BX is it. If you want something that's more of a tractor, the B is it.
You want to mow and a MMM is the right way to mow most of the time, so don't pay attention to those who say it's a pain to take the MMM off. It's not that bad, it's easier on a B than a BX, and the B comes with a drive over deck (that doesn't auto attach). The BX drive-over deck is more fiddly and it tries to auto attach. Rumour has it that the auto attach goes out of alignment and is then annoying, my BX never had drive over so I can't say that from personal experience.
Any of the Kubota models will meet your needs - BX, B, LX, even an L if you're OK with rear mower and rear snowblower. But the BX and B are really the right machines for someone stepping up from a ride-on.
