Abstract
Snowplow blades can be immediately varied in length at one or both ends by providing extensions of the same shape as the blade, which extensions carry studs which are received in sockets, preferably lengthwise of the back of the blade. The studs are pinned in the sockets for quick and easy fastening and removal.
