Snow pusher

They do this by being constructed with a curved moldboard that lies perpendicular to the direction of travel and a sidewall at either end that keeps the snow contained.

Initially, they were not produced by manufacturers, but they were recognized as a good idea by snow removal professionals who either welded their own or contracted to have them fabricated.

For a long time, the most common snow pusher design was to take a septic tank or other large steel cylinder and cut it in half, then build a mounting system on the back to attach it to a machine.

Though the snow pusher might seem like a simple product, there are many variations across the industry in areas such as moldboard height and angle, sidewall support system (post, wedge, or unsupported), trip edge system, shoe thickness, and rubber cutting edge quality, to name a few.

They employ a tripping system to allow them to pass over obstructions such as uneven pavement or raised manhole covers.

Also, rubber edges generally contour the ground much more effectively than steel because they flex over humps and into dips.
