blade 10 comprises a transversally extending rigid snow deflecting body 12 which has a substantially concave shape body 12 constitutes the upper half of blade 10 and may be made preferably of steel or of any other material which provides the necessary rigidity on the back of body 12 channel 11 extends along the full length of body 12 to import further rigidity as best shown in fig4 and 5 a ground engaging bar 14 extends parallel to and below the snow deflecting body 12 the ground engaging bar 14 has approximately the length of body 12 and may be made of a steel tube 16 nested between the flanges of an angle iron 21 comprising a horizontal flange 20 adapted to slide on the ground and a substantially vertical flange 22 behind flexible skirt 38 as will be described below the ground engaging bar 14 is connected to the snow deflecting body 12 by four arms 24 each bent in the form of a semi circle in a plane perpendicular to body 12 arms 24 have a lower end welded or otherwise secured to tube 16 arms 24 are preferably fabricated from steel tubing the upper end of arms 24 is welded.
