Wow, 1000' drive sounds like a tall order for any GT. That said, the 3 most important things are going to be traction, traction, and traction. If you don't already have any, get some rear suitcase, or wheel weights, possibly both, to go with the tire chains. I ran 4, 42# suitcase weights on a CC 2185 with chains pushing a 40" blower years ago for my 300' driveway. Never had any traction issues despite my living in upstate NY. Can you say "lake effect snow"?
What sort of snowfalls do you get where you live? With a small plow, you may have to hit the drive a few times during a storm while the depth is only a few inches, rather than waiting until it's over.
