I don't agree with this. What takes me 4 hours to clean up with the fel I can do in about an hour with the snow blower. And the snow is gone. Like I don't have to push it any where.
I usually like to pack down about 3-4" before I use the blower. If it get's icy in spring I just run my diamond tooth harrows in reverse and it chews up the ice enough that there is good traction.
I can definitely plow my driveway a faster than I can blow it. But, it certainly depends on what equipment you have, and how much snow you get.
If I had a paved driveway and was inclined to use a blower, I would definitely want an enclosed cab. And, that's not practical for me with the amount of snow we have been getting this decade. I wouldn't be able to justify the cost.
The disc harrow sounds like a neat trick. I spread some sand in critical areas, if it gets icy.
