The article continues the exposition of results obtained in research an agricultural machine for processing soil, designed with applications including exploitation. MCLS complex cultivator was working processes instruments intended soil processing. is a modulated (it can work three widths: 1, 2, and 4 m, tractors different powers) that to use wide range bodies.
 experimental data structure width 1 m their within framework theory random vibrations are presented this article. analysed as supports active body. As result, main characteristics exposed: distribution function, average value, autocorrelation, frequency spectrum. These general regarding used several critical design, execution, exploitation some subassemblies assemblies machines type. are: estimating probability occurrence dangerous load peaks, counting selecting peaks produce fatigue accumulation material bodies, identifying design deficiencies or defects regime, effects on quality All outcomes comprised pursue well-known objectives modeling machines: safety at work, increasing optimizing energy consumption, productivity, all broad context obtain compromise situation
