An agricultural working vehicle has a plurality of working assemblies, at least one control unit for influencing the setting parameters of the working assemblies, a memory unit, and at least one display unit, and it is configured such that even an untrained operator may optimize the setting parameters of the working assemblies in a rapid, reliable manner. An expected change in the function and/or the working result of individual working assemblies or a plurality of working assemblies is depicted in the display unit in a manner that depends on how an operator influences individual setting parameters of the working assemblies.
