Did you ever wonder what snow-swept Mainers did before snowplows? It turns out that Maine was a leader in developing ways to get rid of snow. Initially, communities recruited armies of shovelers.
This was followed by two contradictory methods. One was to pack the snow down so that traffic could travel on it. Teams of horses or oxen (and tractors later) would pull heavy logs or heavy wooden rollers over the snow to make it as hard as rock.
The other was for the animals or tractors to pull a “snowplane,” a contraption that looked like a huge carpenter’s plane made of wood and a blade with side funnels; it would shave the snow off roads and dump it onto the roadsides.
As trucks with strong engines developed in the 1900s, a conceptual breakthrough happened: Why not push a plow rather than pull it? The credit for inventing, patenting, and building large truck and tractor plows with internal controls goes to Don A. Sargent of Bangor, Maine.
