In order to develop the correct automated equipment, the demands and condi-tions for their use must be comprehensively defined. The initial development of the equipment, therefore, should be investigated closely in connection with the process of the different plant types and rows. A method to determine the average level was used to generate a control signal for an automated machine. Laser sensor as well as two different ultrasonic sensors were tested in static and dynamic studies. Contrary to a laser sensor, which delivers an almost permanent signal, the ultrasonic sensor only provides intermittent test values. he characteristics of the developed test device were analysed at the begin-ning of the control period. The main factor which effects the behaviour of an automated side drive proves to be the speed. Other parameters, for example the type of soil or its condition, play a secondary role. A model controller was developed on the basis of analysis of simple control s2ructures. A mathematical drive model, which describes the theoretical drive run of the test device, was used as the basis for the model controller. he economical examination of the implementation of an automated drive device is realised with a model calculation with two different farm sizes. Two differ-ent machines and four different crops were taken into account in the model trial. The trail only covers the implementation in the automated weed control. By both types of activity, the implementation of an automated device proved to bring economical advantages in comparison to traditional methods.      «
