I can say from first hand experience that grain scoops are not necessarily the most practical snow shovels. The blades are usually too big to fit where you need to reach and when full of snow too heavy for most people to move easily.

Also, the plastic models are too flimsy for firm snow and ice and the the aluminum blades eventually crack. The aluminum blades can be cut down to remove extra material, making the blade more rigid and functional. If weight is a concern this is an option; although, for a vehicle shovel weight isn't a real concern.

A sturdy, inexpensive D-handle flat edged, transfer or spade type shovel works great. It can break through tough snow or ice, clear snow from under the vehicle and will last for years.

Supplement this with a sturdy snow shovel, like those carried by back country skiers, for lighter duty work moving snow and you are set.
