Modern controlling and guiding of combine harvesters

The beginning of the 70-ies in the last century was marked by the implementation of more complex informational systems on universal combine harvesters. Automatic machine guidance was implemented, as well in order to relieve the driver, especially in combine harvesters operating at high working speeds. There is a difference between controlling and measuring instruments and the instruments for the automatic regulation and guidance. Information technology and electronics in measuring instruments as well as the use of computers in combine harvesters make possible the follow: measuring of the harvested area, control over the grain loss, control over the grain yield in the whole harvested area as well as in some particular parts. Further they enable the carting of the area according to the yield, frequency control and the encumbrance of the important axes, also guiding a combine harvester to its most optimal permeable level, connecting to a satellite way of guidance, registering engine troubles in order to fix them on time and getting the right information about the timely servicing of combine harvesters. Except for the above mentioned features big capacity combine harvesters show some other possibilities such as: possibility to establish a connection with other computers in order to get the information needed, automatic guidance of a combine harvester maintaining the direction of moving possibility for the automatic regulation of the mass flow through the harvester as well as some other possibilities since such instruments have been developed and constantly built in new kinds of harvesters. Finally it is the system of controlling a combine harvester by a satellite positioning. Lately some researches have been performed considering the equipment in use GIS- for the automatic (robotized) controlling of a combine harvester. Such kind of combine harvesters have not yet been used in our domestic agriculture and some effort should be made to implement them in the exploitation.
