It's an interesting challenge to sort through all the product positioning hype and factual info to make the best decision. Two weeks ago, I was on a
B7500 that I really liked. It and the BX felt spartan, but real solid as if I could never damage it. However, I didn't feel like the orange machines were as responsive as the 400 series I own and the new X series and 4110 I tried. The comfort and responsiveness was definately less at a gut level for me.
When I operated the 2210 including use of the 210 loader and 62C deck, it seemed to bridge the gap between the comfort and convenience of the X series and my 400 series garden tractor and the "industrial" feel of the Kubotas. So the 2210, albeit a bit more expensive than a similarly equiped BX, was the best tractor for my needs and my gut feel.
Deere actually calls the 2210 an "Advantage" tractor which is
their way of saying it is an economy spec tractor. I believe
they position the tractor this way so as not to diminish
their efforts to promote the 4X10s as the premium CUTs on the market. However, the 2210 specs are close, indeed, to the BX which is their way of maintaining what
they believe is their competitive advantage. Essentially, they are telling me and other consumers that, if we really want a cheap sub-compact like the BX, they have one too. But if you really want the best of the best, move up to the 4X10 series.
FWIW, I don't feel the BX and the 2210 are "economy" tractors at all and each have their advantages. I will agree with Cowboydoc that you can do a one-stop comparison of all the different sizes, varieties, and perceived "luxury" levels at one dealership now. If I could have three tractors of my choice right now I'd have and X495 for mowing, a 4115 for light loader, landscaping, and snow removal, and a Kubota Grand L for leveling small buildings, trees, and for moving my share of the County around wherever I want it to be.
