<p>The distributor has a retractable sowing element guide rail frame (2) for accommodating of a set of sowing elements (7) pivotably connected with the frame. The sowing elements are subjected with traction force by a tension spring (3) in a direction of a farmland (5). The sowing elements are pressurized with force directed against the traction force by the spring during retraction. The spring is used as a pressing rod for pressurization of the elements in a transport position and/or turning position against tractive impact of the elements in a working position.</p> |
