ABSTRACT:
The present invention comprises one or more anti-drift stabilizers mounted on the leading edge of a snow plow's blade. These stabilizers are mounted at an angle that is in the same direction as the angle of the snowplow in relation to the plow truck. As snow or other media is channeled to one side of a plow blade it exerts a force in the opposite direction thus tending to cause a plow to want to knife or drift in a direction opposite where the snow or other media is being deposited by the blade. As snow or other media passes over the surfaces of the stabilizers it exerts pressure that is opposite to, and counteracts the knifing action created at the emptying end of the plow by the accumulation of snow. The result of this is that the plow can be operated safely without the need to make constant corrections for the knifing and without the added danger of the inattentive operator being pulled from the roadway or into oncoming traffic and causing property damage or personal injury.
