Abstract

Evaluation of new technologies in agricultural machinery guidance is very important and can help producers choose the right equipment for their applications. At present, comparison between different guidance systems has been typically based on the amount of a guidance error (i.e. deviation of the vehicle from the desired path). Accuracy of a distance between two adjacent passages, it means the precise pass-to-pass continuation of a particular operation in a field, when using satellite navigation depends on many factors. For instance received DGPS signal accuracy, the steering system precisions of the whole tractor-tool unit as well as human factor are the most important ones. Without using the satellite navigation during a field job, a tendency to passes overlapping was found out. It means that the real width of a machine passage was smaller than full machine’s working width (pass-to-pass overlapping) due to the operator’s poor pass-to-pass continuation estimation. Working width was the most influential factor in this case. Generally, it is possible to say that the GPS based navigation systems utilization is possible for almost all mechanized field operations. Nowadays, new possible applications of those systems are dealt with, regarding mainly soil protection from erosion and compaction. Machinery passages in a field are for current agriculture practices inevitable but their ordering is usually random. Concerning total field area affected by machinery passages, the following facts were found out during comparison of three different farming systems. The system with ploughing showed up to 88.2% of total area covered with wheel passages (counting all operations in the field during one year), conservation tillage system showed 65.2% of the area affected and no-till system revealed 42.7% of the area run by machinery wheels. To sum up the results, the experiment revealed enormous intensity of agriculture machinery passes in fields which could be a potential risk for good soil conditions. Following from that, the navigation and better accuracy of machinery passages in fields can help in further development of system for soil compaction protection.
