Thanks for all the suggestions. I feel like I'm in between a normal household lot and a real rural lot size. I've got more concrete than normal at around 6000-7000' of concrete area, but I don't have all the needs of a big rural lot because I'm just under 2 acres.
I'll probably use some combination of BPTactical's suggestion of waiting until it melts and my existing Honda 28" 2-stage snowblower. In reality, snow tends to melt pretty quickly around here. The only thing I'll really need to clear is the driveway and even that isn't truly a necessity because it's flat and I drive an SUV in the winter.
The big 3500' of concrete by the outbuilding can just take its time melting. It faces west and has a pretty unobstructed view of the afternoon sun so it'll melt fairly quickly anyway.
I'll probably just tough it out this winter and see what tractor weaponry I end up acquiring before next winter season. I was really hoping someone would just tell me that the Walker mowers are fantastic with a plow blade and I'd end up buying that attachment. Oh well. I'd rather know before I spend $$ on the Walker blade.
Thanks again!
