There are more than one Dearborn front plow blade that mounts to the underbelly framework. There is the snow plow blade, a dirt dozer blade, and a V snow plow. Yours appears to be the dirt dozer blade as there are no trip springs on the plow like the snow plow blade had and the sides of your blade appear straight like the dozer blade. The snow plow also had rounded side edges that cute a straight side edge when the blade is angled. I'm sure folks have used the dozer blade to move snow, but have to be careful not to hit an immoveable object and injure yourself or tractor since there are no made trip springs.
