Economic requirements for modern agricultural machinery keep increasing due to the high demand and the strong global competition in the production of food products and biomass products. In order to put themselves in an optimal position on the market, producers keep asking for more and more efficient machinery systems that combine a high power of impact with the best possible quality of work while generating low costs. This requirement profile results in innovation pressure on the manufacturers of such modern agricultural machinery. The new developments and innovations in the area of agricultural engineering can currently be separated into two categories. On the one hand are mechanical developments of the machinery systems. Due to the high technical standard of the systems, these developments are subject to an evolutionary process and focus on detail optimisations and enhancements of machinery systems that are already known. Revolutionary new mechanical developments can also be found but are a minority. Due to the growing dimensions of the machinery, the limits of the legally and structurally possible are already tested, especially in Europe. As the European market has a share of approximately 33 % in the global production volume of about 80 billion Euro for agricultural machinery and tractors, the beginning of the end of the growth on the European market has a significant global impact despite the expected share decrease in the coming years due to global economy developments. On the other hand, the innovations in agricultural engineering are nowadays primarily marked by developments in the fields of electronics, sensor technology and software. The focus lies here on the consideration of an agricultural machine or machinery as a complete mechatronic system, with the aim to optimise the existing work process by enhancing it with intelligent functions with regards to efficiency, precision, environment and cost. Motivation in agricultural engineering for this course of action derives from the drivers often not being able to use the full potential of an agricultural machine system due to the increasing complexity of agricultural machinery and the required know-how. For seasonal machines in particular, the yearly re-learning of the machine usage and the lack of concentration at the end of a season reduce the degree of exploitation and productivity. Automatisation or semi-automatisation of work processes liberates the driver from continuous or frequent intervention and enables him to monitor the superior work process, while the respective machine function is kept in optimal operation mode by controls. As a result, mistakes by the driver can be reduced to a minimum. Against the background of this partly limited growth, this course of action makes it possible to increase performance significantly while maintaining the size of the machinery, thereby meeting the above-mentioned requirements of the agricultural producers for agricultural engineers. Moreover, this normally generates cost benefits because the identical performance increase of an existing machine system is easier to put into practice this way than by mechanical enhancements. The described machine-internal work-process optimisation is enhanced by adding innovative data management systems that link the complete overall operating process with public and corporate sources of information and thereby enable new possibilities of field and operation management. If used consistently, this enables mapping and optimising the complete process and operating chain from farming to the end customer in a networked structure.
