In this manner and the bucket can be moved horizontally by means of the hydraulic cylinder Axis can be pivoted relative to the cantilever arm.
  • this is effective as a backhoe, which is aimed at the driver's cab of the excavator is or as a spoon, with which he directed away from the driver's cabin is.
  • the soil is directed towards the cabin is dredged, while in the second case the soil from the Cabin is dredged away.
  • the invention further relates to a tillage implement.
  • the object of the invention is to connect a soil tillage implement with a cantilever arm of a vehicle, in particular a compact excavator, to create that accomplished in a short time in a simple manner can be so that the functionality of the vehicle becomes clear can be increased.
  • the object of the invention is also a specially designed Soil cultivation device to be specified that can be easily and quickly converted can be.
  • connection of the type mentioned at the beginning in that it has an adapter that can be connected to the extension arm is, the adapter with a plug-in receptacle for different tillage devices or for a rotating device for different tillage devices is provided, as well as means for securing the connection of A-adapter and soil tillage implement or rotating device are provided.
