I am sure it will work...Only problem I see is that you are running over the snow with your tires, packing it down and then trying to scrape it.
If I get snow I'll let you know.... For now it works great on the rock drive. And flipping it around I get a better push in reverse when needing to up root catus.A rear blade is nice if you have to level out a gravel driveway. But, is the rear blade you're talking about the same rear blade that is used for moving dirt and gravel in driveways.
I'd get it if it's reasonable. Nice to clear close to the garage door, or just for the added weight. Makes the machine abit longer though.
