Abstract
A snowplow whose blade is joined means of at least two links disposed one over the other to an implement plate which can be fastened to a vehicle plate of a working vehicle has a system which assures the proper operation of the blade even when it passes over obstacles. This system permits an upper and lower link to be raised over obstacles and to tilt the links due to the fact that the upper link or links are made so as to be able to elongate against the action of a spring force.
