A road vehicle has wing-plow attachments and a brush cutter mounted as a wing plow to the wing-plow attachments. The brush cutter has an elongated frame and a series of cutting discs mounted in line along that frame. The wing-plow attachments comprise a wing-plow mast having a first raisable connection and a wing-plow push bar having second raisable connection. The elongated frame is connected at both ends thereof to the first and second raisable connections respectively, such that both ends are independently adjustable in height by the wing-plow mast and the wing-plow push bar.
