On the basis of a parametric finite element model of the supporting structure of a trailed wide-grip sowing complex ATD 18.35, taking into account the mechanical properties of materials of metal structures, characteristics of dynamic effects in the sowing mode, the most dangerous combinations of loads for individual elements of the supporting structure are determined, recommendations for rational design are suggested. The calculated symmetrical scheme of the supporting structure with more than 600 constituent elements was loaded, including a possible asymmetric load. Data on the loading of the spatial frame of the supporting structure were previously obtained as a result of a wide field experiment carried out in the field.
