I live just a bit under the butt of the North Pole, so I deal with huge amount of snow most of the time (12" and up), last week storm bring 40 cm of snow (16") with accumulation up to 3' my QA42A can't deal with that. Here what I learn over the year :
1-For slushy snow a blade or a loader are what you need
2-For up to 8" of dry snow anything can be use.
3-For bigger accumulation you need a 2 stage or a loader.
I like to push snow each side of my drive way and use the 2 stage to clear it after, it work for me!
