Adding an axle and a couple of tires to your snow blade to push vehicles with.

A nice big J hook will snag just any brake line, cv joint or whatever. Lady friends KIAs have a little (PITA) trap door in the bumper, you open and screw in a supplied hook.

I remember a story about some good sumaritans pushing a guy free of being stuck in snow (by hand) and then getting sued because they damaged his car.
