摘要

The agricultural machine (10) has spacers (30a-30n,32a-32n) that are connected with mounted series units (28a-28n). The access units (34,36) are provided with connection ports which are connected with selectable configurations. The respective connection port is formed such that the control units (46,50) are electrically connected only with the spacers in the selected configurations according to the mounted series units.
