martytim,
That's a loaded question. Here you will find no end to the ways we can spend your money! /forums/images/graemlins/grin.gif As for the tasks listed, all of the JD products from the sub-CUT's and up will work; it is just a factor of how much time and money you want to spend at it.
A 2305 sub-CUT, or a left over 2210, would work. The blower would be either a 46" single-stage or a 47" 2-stage. I might be leaning to the 47" for the drifts you describe, but it also depends on what type of surface your driveway has. The blower and front hitch/upstop etc required will set you back about $3K MSRP (this cost would go up on larger machines). These tractors can run a LX-4 (48") brush hog or a 62" mid mount mower, or a 72" rear discharge finish mower.
If you wanted to move up in size (10 acres is 10 acres, and there is no limit to the tasks you can find on it) Deere is still purging their inventory of 4010/4110/4115 tractors (the series is being replaced with the 2520 and the yet to be released 2320). These could be great choices too.
Recently released is the 3203. A hydrostatic variant of the time proven 790. It will not accept a midmount mower or a front blade/blower (you can get rear mount blowers for this machine, but you've got to want to crane your neck behind you).
After that, the 3x20 series and the 4x20 tractors are really nice!
