Distributor machine, especially pneumatic fertilizer spreader, which has a supply container, equipped with outlet orifices, and metering wheels of variable rotational speed, for conveying the material trickling out of the outlet orifices into pipelines connected to at least one blower and provided with outflow orifices which are respectively arranged next to one another, as seen transversely to the direction of travel, and at a distance from one another, the spreading width of the ... by the spreading fans, which flow out through the outlet orifices and are generated by being blown against baffle bodies arranged in front of the outlet orifices, amounting to a multiple of the width of the supply container, whilst the discharge quantity is to be increased or reduced from the tractor seat, during the discharge of material, by a variation of the rotational speed of the variable metering wheels. So that, even in distributor machines of the generic type having a large spreading width of up to 24 m and above, the discharge quantity can be varied during the discharge operation in strip widths which are substantially smaller than the spreading or working width, provision is made for ensuring that the discharge quantity is to be increased and/or reduced from the tractor seat, during the discharge of material, segmentally in segments of the spreading width, preferably starting from a basic discharge-quantity value. |
