A first wing is pivotally connected to a leading edge of each plow board and a rear wing is pivotally attached to a trailing edge of each plow board. Each of the first wings includes an inner and an outer flap which is independently rotatable about a substantially vertical hinge line at the leading edge of each plow board. Each of these rear wings includes an inner and outer flap which is independently rotatable about a substantially vertical hinge line at the trailing edge of each plow board. Suitable devices are provided for rotating the flaps. Ballast passing gates are provided in the main plow board adjacent their leading and trailing edges at the bottom of each plow board.
