ABSTRACT:
A long wearing plow blade which automatically overrides road surface irregularities and obstacles and returns to a snow-engaging position is provided which may be mounted on either the moldboard of a conventional snow plow or on the plow of the present invention. The improved snow plow of the present invention has a substantially horizontal deck trailing the plow blade. A vertically extending deflector baffle with a forwardly-extending upper lip which is integral with the deck guides snow to the side of the plow. The deflector baffle initially tangentially contacts snow being plowed, and in combination with the deck, results in a plow which is less susceptible to the formation of vision-obscuring clouds of snow and side slip when in use.
