Abstract:
A plow system includes a mounting structure configured to mount at a vehicle, with a center plow pivotally attached at the mounting structure. The center plow is pivoted in a first direction responsive to actuation of a first actuator and is pivoted in a second direction responsive to actuation of a second actuator. A first plow wing is pivotally mounted at a first end of the center plow and a second plow wing is pivotally mounted at a second end of the center plow. Responsive to pivoting of the center plow to a first fully pivoted orientation toward a first side of the vehicle, the first and second plow wings both pivot to a forward orientation. Responsive to pivoting of the center plow to a second fully pivoted orientation toward a second side of the vehicle, the first and second plow wings both pivot to a rearward orientation.
