Distribution members (3, 4) of a spreading device are disposed close to each other. The distance (67) between the points of closest approach of the distribution members (3, 4) may be 2 centimetres. The outside diameter of each distribution member may be 35 centimetres. Flow of material to a distribution member (4) of a spreading device is controlled by delivery means (86). The delivery means (86) comprises dosing plates (82, 83, 84, 85) which are independently displaceable relatively to each other and to the bottom (81) of a hopper of the device. The dosing plates (82, 83, 84, 85) and the bottom (81) have openings which cooperate with one another in an adjustable manner which makes it possible to adjust the position of the delivery of material to the distribution member (4) both in radial and circumferential directions, and to adjust the size of the or each delivery orifice. |
