I've got about the same amount of clearing you'd have to do.
For me, in south central PA, the snows justifying a snow blower are few and far between.
However, other then using the FEL to back drag snow away from the garage doors and vehicles, the only other use it gets for snow removal is making piles.
As far as removal from the drive, I use a back blade which is a fairly cheap implement. I angle the blade about 30° and operate the tractor in reverse gear. This works well if you ensure you plow no more then 10" ± 1".
If I could get a great deal on a 3PH type blower (at an auction or something like that), I might do it...but for 150 to 250 feet, I'd just plow first.
For my circumstances, there's better ways to spend the $1200 or more then a rear snow blower.
