Abstract: In the Republic of Serbia, despite a certain decrease in the number of accidents with tractors in the period 2010-2020., the number of injured and killed people is still high. In previous analyzes of the causes of accidents with tractors, the reports were formally reduced to the following: the operator was under the influence of alcohol; unsafe and unsuitable driving on terrains with ups and downs as well as rural and forest roads; malfunctions of controls for: braking, steering, transmission (switching on and off to save fuel), malfunction of tires, etc.; malfunctions and lack of light signaling; failure to establish the necessary ballast in relation to the required stability of the tractor, especially when moving uphill and down slopes; exploitation of a tractor without a cab or a safety frame; weak distraction, non-observance of traffic regulations, tractor driving by minors etc. In this paper, stability was considered when the tractor was moving up a slope, as well as when moving on a side slope through the balance of forces and factors that affect stability, i.e. the angle of inclination at which the tractor could potentially overturn. Those data obtained by analyzing the forces acting on the tractor are very important from the aspect of safety during exploitation in agrotechnical and transport-specific conditions.
