Agricultural pneumatic distributors for seed or fertiliser are to ensure that the distribution material is discharged uniformly in a preselected density on an area of farmland, irrespective of whether travelling lanes for a tractor are to be kept free or not or, for other reasons, some of the spreaders connectable to a distributor head (6) of the distributor are not required. For this purpose, there are provided on the distributor head (6) return conduits (6a-6A) which guide excess distribution material either into a feed conduit (5) serving to convey said material, or into a collecting container. The excess distribution material is thereby either returned to the distribution operation or can be brought out of the collecting container into the supply container (1) of the distributor, and the supply container (1), including the metering device and the conveying blower, can be mounted approximately in the front region of a tractor independently of the rest of the distributor. <IMAGE> |
