In a sowing machine with a seed box (17) and two or more rows of coulters (25), these are divided in a direction perpendicular to the direction of travel into a plurality of sections with their respective carrier frames (21), which are so suspended from a carrier beam (15) as to be movable up and down independently of each other. This enables all the coulters to penetrate into the ground in substantially the same depth, even if the surface of the ground is not quite plane. |
