  • Such an embodiment has the advantage that unintentional loosening or falling of the attachment tool from the attachment tool device, for example. Due to incorrect operation, can be avoided because the securing device secures the attachment tool regardless of the locking state of the locking device on the attachment tool device. Even with an undesirable by incorrect operation unlocking the locking device in example.
  • a excavator arm raised attachment tool means injury hazards are significantly reduced in this way, since the attachment tool not, at least not completely, can be solved by the attachment tool. This contributes to the safety during operation of attachments with replaceable attachments.
  • the attachment tool device can be, for example, a cultivation compressor.
  • the attachment tool may in particular be a compactor plate.
  • the attachment tool device can have an unbalance generator, in particular when configured as a mounted compressor.
  • the unbalance generator may include a hydraulic motor connected to a hydraulic port.
