  • shut-off elements are used to prevent the introduction of granular material into individual outlets, so that no granular material is deposited onto the agricultural area via the row units connected to the outlets, e.g. row-related seed coulters and/or seed coulter modules of the spreading machine.

  • shut-off elements When using shut-off elements, air removal is regularly required in the distribution devices in order to prevent an interruption in the pneumatic material conveyance due to back pressure. To ensure air removal, the shut-off elements can be provided with air removal recesses. However, the air discharge recesses of the shut-off elements known from the prior art regularly tend to become dirty and blocked, so that the amount of air that can be discharged decreases with increasing duration of use. The increasing contamination ultimately leads to increased back pressure, which impairs the pneumatic conveyance of the material.
