ABSTRACT:
A snowplow leveling system is described for use on a standard plow mounting structure having a reversing table mounted to a plow blade system and rotatably mounted on a support frame. The support frame is pivotally mounted about a horizontal axis onto a motor vehicle which has an elevatable lifting point. The snowplow leveling device is mounted on the support bar of the reversing table. The leveling device may include two slider mechanisms mounted on support tracks located on opposite ends of the support frame of the reversing table. Positioning struts hingedly connect the slider mechanisms to the support frame. Additionally, a lifting chain connected at each end to the slidable mechanisms and in the middle to a lifting hitch attached to the support frame aids in maintaining the leveling position of the snowplow system of the present invention.
