Current development trends are associated with the digitization of production processes and the interconnection of individual information layers from multiple sources into common databases, contexts and functionalities. In order to automatic data collection  of machine operating data, the farm tractors were equipped with monitoring units ITineris for continuous collection and transmission of information from tractors CAN Bus. All data sets are completed with GPS location data. Acreage of farm is 2,800 ha and a total of 26 monitoring units were installed since 2015. Data collection takes place continuously from switching-on to the switching-off of the tractor switchbox. Based on machine position information, it is possible to model the machine trajectory. The obtained data provides an overview of the time use of the tractors. These data are then compared with calculated models of optimal trajectory trajectories, based on the shape of the plot. A very small change in direction can be a significant reduction in riding length. With the changing of the azimuth by 1° the total length of rides was shorter about 577 m. An analysis of trajectories also reveals the locations of higher frequency and the accumulation of passes. During the season, some areas of the field are exposed to extreme loads. In terms of control data, there are important data about the working mode of the tractor and the level of the operator.  During machine operation, the fuel consumption, working speed and engine speed were monitored. The recording of the working mode reflects the variability of the environment and reveals the variability of the work which was done at the same time.
