The subject of the study is a motocultivator whose construction is designed for soil cultivation on small-scale private farms. Magnitudes – variables and constants that characterize the statics and dynamics of the motocultivator are identified. The motion equations are derived based on the corresponding body simplifications that move in the vertical-longitudinal plane with two degrees of freedom. The computerized simulation model of the dynamic system was developed using the Vemsim software. The numerical solution has been obtained. After analysis the relevant conclusions are made to improve the sustainability of the motocultivator movement within the required controllability.
