Abstract: A device for disseminating spreadable material, such as fertilizer pellets or powders, consisting substantially of a frame (1) that is pulled or carried, a storage holder (3) for that material, a dosage mechanism (4) fitted beneath the holder (3) and a reciprocally driven spreading pipe (12) connected to the mechanism (4) wherein on either side of the vertical longitudinal plane the spreader pipe (12) is provided with a surface for instance formed by a longitudinal rib (22) guiding the spreadable material, said surface enclosing an angle .alpha. with the vertical and extending at least over a part of or over the whole length of the pipe (12) so obtaining an even spread of the material and in particular a symmetrical spreading pattern.
