This device comprises a tank for the product to be spread, a pump inserted in a conduit connecting the tank to a spreader system, a regulating valve actuated by a driver. An electronic system controls the driver as a function, on one hand of the speed of the vehicle and, on the other hand, of reference data. The regulating valve is inserted in a regulating conduit which is connected in parallel with the pump. The electronic system comprises a regulator including a microprocessor which is, on one hand, connected to data encoders for encoding data relating to the amount of product to be spread per unit area and to a parameter relating to the type of spray nozzles to be chosen for said spreader system and, on the other hand, connected to at least one interface circuit connecting the microprocessor to a speed detector and a pressure detector and to an interface circuit connected with said valve.
