A blower spreader for agricultural spreading material consists of a drawn or semi-mounted container with a bottom inclined in the manner of a ridge roof on both sides of the longitudinal axis of the vehicle, a plurality of spreading tubes which extend on both sides transversely to the longitudinal axis of the vehicle and each terminate at a different distance at spreading orifices and which are combined in groups, and a blower loading the spreading tubes with conveying air, the bottom having, at each of its two lowest points, a number of outflow orifices corresponding to the number of spreading tubes on one side, under each of which outflow orifices an injector of a spreading tube is arranged. The metering of the quantity of spreading material takes place via a number of continuously adjustable slides corresponding to the number of groups of spreading tubes. An axis-parallel rotating or oscillating agitator is arranged respectively above the outflow orifices in the region of the lowest points of the bottom.
