US Patent 7591087 Flow divider for snowplow wings

A snowplow assembly may include a snowplow mechanism having a frame and a pair of wings that are adapted to move independently. The snowplow assembly may also include a hydraulic system that has a first cylinder for use in moving the first wing, a second cylinder for use in moving the second wing, a pump system for use in providing hydraulic fluid to the first and second cylinders, and a flow divider that causes the first wing and the second wing to move at substantially the same time and substantially the same speed regardless of the disparity of loads on the first and second wings.
