This article is devoted to the analysis of the kinematic and aerodynamic characteristics of the model of the working bodies of the haulm topper. The problem of removal of lodged tops of vegetable crops was investigated on the basis of finite element analysis of the model. Obtaining data on the density and air flow rates inside the casing of the topper is an urgent task. The aim of the work was to analyze the air flow rates and air pressure during the operation of the topper. The Solidworks FlowSimulation package was used to build and simulate a numerical model of the working bodies. Numerical modeling of the haulm-removing organ obtained maps of the distribution of velocities and pressures in the cutting zone of the haulm. Average values of air flow velocity (12-30 m/s) and pressures inside the casing (1.5-2 kPa) ensure the rise of the haulm to the cutting zone of the knives.
