The trough of the trailer can be tilted electronically to the right and left. The existing remote control module can be used for this purpose. At the rear of the trailer, red and orange LEDs serve as taillights and turn signals. This item is powered by a supplied data cable from the trailer to the tractor. An additional battery with a charger is not required for operation. Please note: The model variant without its own power supply has only been available since January 2012. If you have an older version of the model, it still has its own power supply.
