A snow-plowing apparatus provided with a snow-removing member detachably attached to an end of a holding rod of a hand-pushed mower, in which an engine and a wheel are attached to a frame, having a detachable rotation transmitting portion, to which a mowing blade is attached and rotational driving force of an engine is transmitted, on the end of the holding rod extending from the engine forward and downward. The snow-removing member is provided with a snowplow rotating body rotated around a horizontal axis through the rotation transmitting portion to plow and shoot the snow. The snowplow rotating body is composed of three short rotating bodies. Each of the short rotating bodies has four snow-plowing blades disposed in peripheral direction with a predetermined pitch. And, the snowplow rotating body is composed of the three short rotating bodies mounted on a shaft body as the snow-plowing blades are dislocated one another in the peripheral direction.
