hi! if you can specify which region/culture you're interested in, that will assist the appropriate historians to find relevant answers. In the mean time, here are some previous responses to get you started:

• Snow shovels, snow blowers, window ice scrapers--when and how were they invented?

• Before machines removed the snow from roads, what happened when the heavy snows came?

• Blizzards and snowstorms: How did people in your area of study survive harsh winters?

• How did Medieval cities deal with heavy snowfalls?

In addition to the earlier references, realize that a primary concern with snow removal today is in vehicle safety. Automobiles travelling at 100 kph don't generally track well in snow and ice.

In an age prior to motorized transport, when you got around by walking, by draft animal (horses, donkeys, oxen), or by sled, there was far less of a need to clear all snow. You'd still need to shovel clear building entrances, etc.

But the problem domain was different.
