We get lots of snow around here and although I don't know of anybody who uses a boxblade as a complete snow-removal tool, there are people(myself included in the upcoming winter) who leave them on to compliment a FEL, or front blower. It can be used to grade with, as a rear weight, or to back in and pull snow out of tight areas. There might be other uses to during the winter, but those are the ones I am planning to use it for.
