A spreader for spreading granular and/or powdery materials having a hopper and rotary distribution members with ejection blades on plates located below the hopper. The areas covered by the two distribution members can be adjusted so that they substantially coincide with one another. In some embodiments, the orientation of the ejection blades on the plates can be adjusted. Material flows to the distribution members through feeding means that include outlet openings and ports that can be in register with the openings. Also, displacers or closing members for affecting this flow can be positioned near the outlets at the lower portion of the hopper. A transmission, including change speed gears, can be connected through endless flexible members, i.e., ropes or belts to the shafts mounting the distribution members.
