A blade assembly and a vehicle including the blade assembly is disclosed. The blade assembly includes a main body vertical blade portion and a pair of wings pivotally mounted at the ends of the main body. A hydraulic cylinder attached to each wing pivotally moves each wing relative to the main body, the cylinders being operatively connected in series. Each wing is configured to rotate through a range of rotation substantially equal that of the other wing but includes a different radius of rotation than the other wing.
