The major issue of safety in agricultural production is the safe operation of the agricultural machinery and the safety of its operators. This phenomenon is relevant in the mountains and under mountains areas, where to which most European countries belong including Slovakia. The routing of machinery is very often on sloped and uneven ground. For this reason, the most cases of accidents are vehicles overturning. The dynamic forces acting on the vehicle are causing the overturning of the vehicles and causing the operator injuries and property losses and ecologic damage to the natural environments. Research on the processes of overturning, behavior of the dynamic factors during the ride, preventing accidents, developing the mathematical models, and verification of the experimental measurements are the main topics of this book.
