The BH130 Smart Backhoe does more than just turn an indicator light on in the cab; although it does that, too. The first step is attachment recognition. The D3 host machine recognizes that there is a BH130 attached to the machine. This activates a dedicated machine display to allow options for the BH130 to be selected. And as a Smart attachment, the BH130 allows for pattern change. That is, the existing machine joysticks are re-purposed to perform functions on the attachment.
