Abstract of the Disclosures: An apparatus for spreading granular material, such as fertilizer, has a carriage on which there is mounted a vertical conveyer which comprises a vertical cylindrical housing and a conveyer screw rotatably mounted therein. The screw is rigidly connected at its lower end to an infeed cup and directly connected to a driving mechanism below the cup. The cylindrical housing and the screw wing of the screw extend down- wardly into the cup and the cylindrical housing has guide means conducting the material inwardly towards the screw blade of the screw. The material is supplied from a supply container directly down into the cup. At its upper end, the screw is non-rotatably connected to its spreader to which the granular material is conveyed via a discharge opening in the cylindrical housing and a distributor plate. The effective through- flow area of the distributor plate, as calculated per angular unit in the circumferential direction of the cylindrical housing, varies and is smaller at the be- ginning and at the end of the discharge opening of the cylindrical housing.
