A spreading implement has a container with ports that lead into an air chamber pressured by a blower device. Delivery ducts communicate with the chamber and ports to receive material from an ejector disc rotatably mounted adjacent the ports. The ducts extend horizontally from the ports in a direction transverse to the direction of travel. The ducts have outlets that are spaced apart from one another and each outlet comprises a movable spreading member located adjacent the outlet end. The spreading members can be flexible hoses or pivotable discs that are rockable by a common driving mechanism or the members can be bladed or rotatable nozzles so that during operation material is spread over a wide area by each spreading member.
