The system has a particle distribution controlling autonomous module (35) for controlling opening and closing operations of a particle supplying device. The module includes a reception unit for receiving opening and/or closing control signals delivered by a guide bar (32). The module includes a conversion unit for converting the control signals into opening and/or closing commands of actuators (36-1, 36-2) such that the actuators are controlled by the control signals generated by the guide bar. An independent claim is also included for a method for automatic distribution of particles for an agricultural machine.
