ABSTRACT:
A side wing blade assembly for a vehicle, comprising an elongated blade, an articulated coupling between the front end of the blade and the vehicle, and an articulated attachment system to connect the rear end of the blade to the vehicle. The articulated attachment system includes a pair of vertically spaced apart and generally parallel arms, each of these arms including one end universally mounted to the rear end of the blade and another end universally mounted to the vehicle. A fluid ram having one end connected to the vehicle and another end slidingly engaging one of the arms is used for raising the blade off the ground toward a retracted position. Stops are provided on the arm receiving the fluid ram in order to limit the sliding movement thereon, forcing the fluid ram to act as a dampener as a result of an excessive upward movement of the blade caused by an impact on an obstacle.
