ABSTRACT:
A spreader for granular and/or powdery material such as fertilizer comprises a hopper having two delivery parts. Distribution members are provided under the delivery parts for broadcasting material fed to them from the hopper. The distribution members are mounted on a carrier rigidly supported by the hopper. This construction results in a fixed position of the distribution members (3, 4) with respect to the delivery parts, regardless of deflections which may occur as a result of the weight of material in the hopper. The distribution members may be driven by a mechanical transmission from a power take-off shaft of a tractor, or by a hydraulic motor.
