The invention relates to a seeder for scattering seeds and/or fertilizers. Said sowing machine comprises a frame (1), a storage container (9), seed coulters and depth control rollers (8) that are associated with the seed coulters and are mounted in an inclined manner in relation to the direction of travel. Each seed coulter (7) is associated with two depth control rollers (8) which, when viewed from above, are positioned in an inclined position which opens out into a V shape in the direction of travel for controlling the depth of the seed coulters (7) in the earth and for at least partially reintroducing the earth that is thrown by the seed coulter (7) from the sowing furrow to the side back into the sowing furrow. The aim of the invention is to produce a seeder with depth control rollers (8) having an essentially reduced risk of obstruction and without scraper elements. The depth control rollers (8) comprise, at least in the external radial area (20), a holding disk (8) that is configured as an annular disk such that, respectively, the rod-shaped support and compression elements (21) are arranged at a distance in relation to each other, in the at least approximately axial direction in each of the external radial areas (20) of the annular disk (19). |
