The present invention relates to a system for controlling the operation of an agricultural implement (1) using a tablet computer (14), where the interaction with the implement is done via one or more graphic user interface on the tablet computer. The tablet computer is coupled to a communications module (4) which in turn is coupled to an electronic terminal (2) which controls the operation of the implement. The communications module (4) manages the transmitted data between the tablet computer and the electronic terminal and the positioning units or sensor units coupled to the system. This significantly reduces the costs for the farmer as the operation of the implement and any applications associated with the implement is managed by the tablet computer. The tablet computer allows the farmer to plan and document the work by using the tablet computer, and to use it for other purposes, such as navigation, emails or the like.
