A plow is supported for movement with respect to a frame of a vehicle with a lifting cylinder and a rolling cylinder. The lifting cylinder and the rolling cylinder are pivotally connected with respect to each other by a bracket that is pivotally supported by the frame. By this connection, the rolling cylinder can freely rotate with the bracket, thus increasing the plow displacement in both a raised and lowered position without adversely affecting the aggressivity of the plow while grooming terrain.
