I've used plows on a 149 and an 1862, the plow does a great job.
I've spread topsoil with a blade and it worked great.
I prefer a blower for my cement drive, in a bad storm, the snow doesn't build up because I can throw it 25 feet or so.
I use weights and chains with both.
I've never had Ags on a Cub, I suspect the chains give more bite on packed snow.
