Various factors affect the performance of mobile agricultural machinery, including the impact of the operator and external loads. The analysis of these factors is an urgent task, since the identification of patterns of their occurrence allows, if not to eliminate the cause, then to predict the malfunction and adjust the equipment of service centers. Various methods and criteria are used to assess the resource of machine units: an approximate assessment of reliability characteristics was carried out on the basis of statistical material on the submitted failures of 180 machines (NΣ=180), which was the result of incomplete resource tests; differential equations were compiled using the Lagrange method. During the resource tests and according to the results of operation, material was collected on the failures of the undercarriage units of the combine and breakdowns of their parts. The developed model of the combine allowed to perform an amplitude and frequency analysis of the chassis of the chassis system when driving on country roads and to assess the smoothness of the machine and the working conditions of the operator. In addition, it allows you to rationally choose the speed at which over-resonant or pre-resonant ranges of operation will be provided.
