All advice and observations above are right on. In particular, I'd second snrub's recommendation to pay attention to the seat suspension, even if you have a good back. My next upgrade for my present CUT (compact utility tractor) will be a new seat arrangement. My back holds up to 8 hours of running small or large chainsaws, but put me on my Ford 1720 for a few hours of logging or snow plowing, and I'm stiff and sore.
If you like to research the internet, you might try tractorbynet.com for info about sizing, brands, dealers, pics, advice, DIY projects, on and on. IMHO, that forum approaches Pondboss in usefulness.
And, do your best to keep the tractor out of deep water. But come to Pondboss for help if you need to retrieve it...
