ABSTRACT:
A plow assembly includes a pair of plow wings which are pivotally mounted at opposite ends of a center plow. Each of the plow wings may pivot between a forwardly angled position and an aligned position. The plow assembly may pivot a trailing plow wing in response to the center plow being urged or angled toward that side of the vehicle. The plow wings may be oriented in their forwardly angled position until the center plow is at least substantially urged or pivoted toward its angled position or toward a position between the center position and the angled position. The trailing plow wing may be pivoted or urged to its aligned position in response to the center plow being substantially urged or pivoted toward its angled position or toward a position between its center position and its angled position.
