Agricultural machinery is machinery used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed.

Method for controlling agricultural machine systems

For controlling several agricultural machine systems during operation on a territory, based on a reference line, an optimized route for working the territory is determined for the particular machine system, and the particular machine system is driven along this route. The reference line is determined by recording a reference path that was driven along with a first machine system, and the first machine system is controlled based on this reference line with consideration for the working conditions of the first machine system. This reference line is also transmitted by the first machine system to at least one second machine system, which is controlled based on this reference line of the first machine system and with consideration for the working conditions of the second machine system. A corresponding control system for controlling several agricultural machine systems during operation of a territory is also described.
