To assess the quality of the agricultural operation performed, the "degree" of straightness of the trajectory of the unit is of great importance. That is why a number of concepts and evaluation indicators are introduced in the scientific literature to assess the trajectory of the movement of aggregates. One of the main concepts that characterize the quality of the trajectory of the unit is the stability of the motion in question. Stability of movement is a rather broad concept. In relation to mobile agricultural units, the stability of movement should be considered in the plane of the field surface and in the longitudinal-vertical plane relative to the field surface. The slope of the terrain has a particularly significant effect on the stability of the movement of agricultural units in the field plane. By the stability of motion in the plane of the field, we mean the preservation by the unit of a given direction of movement. [1-5] During operation, a number of disturbances act on the agricultural unit, tending to deflect it from the given direction of movement. If we assume that the tractor controls are blocked, then in order to maintain the original course, the unit must have a lot of inertia, but this will help only with small impacts and with the ideal condition of the tractor chassis. Usually, under the influence of random disturbances, the unit, having traveled some distance, deviates from the given direction. Playing a certain role in maintaining the original motion, the inertia (mass) of the unit cannot be a decisive factor in this matter.
