摘要：
Viewed in the direction of travel, fertiliser coulters and swivel-mounted seed coulters 13 are arranged at coulter arms 40 on the frame 6 of a pneumatic precision seed drill. Between them there is a working device designed as a roller 15, which is designed for the re-compaction of the soil thrown up by the fertiliser coulter 12, the pre-compaction of soil between the working device 14 and seed coulter 13, and as a depth guidance roller for the precision seed drill.
