Spreader for granular or powdered material, including a tank for the material to be spread, supplying two spreader members, located in the same horizontal plane and driven rotationally in opposite directions about substantially vertical axes so that the two spreader members spread the material over two sectors which substantially coincide, characterised in that the vertical planes 70 and 71 parallel to the median plane 29 of the machine and passing respectively through the axes of rotation 72 and 73 of the spreader members 3 and 4 pass through orifices 66 and 68 in the bottoms of the hoppers of the tank 2 through which orifices the material is brought to the spreader members 3 and 4, which are identical but symmetrical to one another with respect to a vertical plane 29 located between the said spreader members 3, 4 and extending in the direction of forward travel 195 of the machine, the ejection vanes of one spreader member being offset with respect to those of the other ejector member. <IMAGE>
