A. If the belt tries to pack wet heavy snow between the belt cogs and gear cogs it will cause the belt to over tension and the belt may snap. This is only a problem if your belt drive cover is off while riding, or you have broke your deflector and it is off completely.
The new belt drive deflector for 2017 has a lip that locks in the belt drive cover, and it has been thickened in key areas and is made out of a new stronger material, plus it keeps snow 100% out of the belt drive assembly.
We have had customers ride in light powdery snow with no cover and not have an issue, but we do not recommend that. However if you are in a jamb and need to ride out with no cover or deflector, just ride out following in a buddies track.
Always make sure the belt area is clean and the drive cover is secured properly.
