摘要：
The invention relates to centrally adjustable positioning elements for devices for piling up, collecting or cultivating soil or mulch, which according to the weight of the device can be applied on top, on the bottom, or linearly. The positioning elements each have toothed segments having a plurality of teeth which are connected to chain link-type pinions that are fixed in the adjustment direction but are flexible and rotatably mounted. The chain link-type pinions are designed to be flexible, displaceable or pivotable in such a manner that upon rotation of the chain link-type pinions through 180° the toothed segments and hence the devices are offset by the amount of one tooth spacing and changed in the working position thereof, and at the same time the chain link-type pinions are moved to and fro by half the tooth spacing.
