You have to try to plan for the worst case plowing scenario, and get whatever would handle that. Might be more cost up front, but when you’re in the middle of that worst case scenario, you’ll be thanking yourself.
Example - I’m in the northeast (central NY). If we are about to get hit with either lake effect or a Nor’Easter, there is likely going to be alot of wind (blowing and drifting). It’s pointless to plow with the storm, because the wind will fill everything back in right away. If you’re making snowbanks/piles, it will be even worse because the banks will cause worse drifting.
In those cases, I wait until the storm seems to be winding down to plow. I am comfortable with that, because I know the equipment that I have can handle it.
