Abstract: A working machine is frontally provided with a structure for removably supporting an implement. The implement which is removably supported is a frame which transversely shiftably mounts two forwardly projecting lifting tines. An electrically powered adjusting device mounts the lifting tines to the frame. An electrical cable which provides electrical service from the working machine to the adjusting device includes a two-part connector the parts of which are automatically plugged together and separated as the frame is mounted to and demounted from the working machine. A locking device is provided for mechanically fixing a selected position to which the lifting tines have been adjusted.
