Hey smartguyz -
Sorry it took a while to get back. I saw your post this morning before work but didn't have time to respond.
Anyway - I too was concerned with the size. Well let me tell you, there is a difference in size, but the 2210 is much more maneuverable than the 332. I have the 62" deck on the 2210, and it trims closer than my 332. I was astounded by the turning radius of the larger machine. It will turn sharper than the 332. And with the added width of the 62" deck, your mowing turning radius is reduced even more. If it weren't raining out right now I measure it for you. Don't let the figure if 7.5' bother you. It can't be right or not comparing the same thing. Trust me, the 2210 turns sharper than the 332. When I first test drove the 2210, I just couldn't believe how tight it turns. As far as size, it is a little bigger, but not too big at all. The only thing that took a little getting used to is the ROPS. First time mowing with it I really took my time under trees etc. Then with a little trim job, get it to where I have no problem.
Best thing you can do is try one. If your dealer doesn't have one in stock, then its kind of hard.
My honest opinion - I just loved my 332, and had a very hard time thinking about parting with it. At first when I saw the 2210, I thought it was overkill for me. Thought about it for a week or so (sleepless nights!), and finally went for it. I've had it for over a month now, and have about 25 hours on it using it for mowing. I'm so glad I got it now. Also, I thought I'd never use the 3-point hitch and rear PTO, but got a brush hog for it last week to do some jobs.
All in all the 2210 is a fantastic machine, and is just like a "step up" from my 332.
Here's a photo of the 2210 and 332 side by side. Maybe it will give you a feel for the size difference. If I can answer any more questions, don't hesitate to ask.
Here's a link to a series of photos I took on delivery day, with my trusty old 332 going away.
