“…Interesting study examples for spatial variability are presented in (Jurado C. S., et al, 2012;Tekeste M., et al, 2005;Uzielli M., et al, 2005), and (Pieczyṅska- Kozlowska J., et al, 2021;Lu H., et al, 2022;Salgado R., et al, 2015;Zhang W., et al, 2015) for a property used in the characterization of soil resistance, namely the cone penetrometer test. A large number of works describe the variability of the tensile strength of agricultural machines intended for soil processing (Al_Neema K.A., et al, 2021;Al-Kheer A.Al-K.A., et al, 2011;Markinos A.). The random nature of the forces generated by the action of the working bodies of the soil processing machines is primarily motivated by the inhomogeneous characteristics of the soil (density, granular composition, physical composition, humidity, chemical composition, etc.…”

The investigation on the unpredictability of the distribution of traction resistance forces on the working bodies of a specific type of MCLS complex cultivator is presented in the paper. The validation of the random character of the force that loads the active bodies is used to indicate the mathematical model that must be followed for the research of the soil processing system. Also, the research results elucidate some hypotheses issued in the conception and design of the machine: the more intense load for the working bodies from the lines of working bodies located immediately after the tractor, the existence of working bodies that are constantly more intensively requested and the causes. According to the literature, it is to be assumed that the forces that demand the working bodies, the supports, and the machine frame have a random nature. The conclusions of the descriptive, inferential statistical study (which do not quantify the random intensity) are explained together with the results. The experimental loads are compared to some of the most random strings to produce a quantitative estimate of the random intensity. As a result, processes that use random functions and the entirety of their approach are recommended in mathematical modelling for further research

“…The authors [20] consider linear regressions formed with combinations of dimensionless parameters. The authors [26] present the results of the calculation of the coefficients of the classical calculation formula for the resistance force, given in [27], both on the direction of travel and on the vertical. The formula for calculating the soil tillage draft force assumes from the start that the exponent of the working speed is 2, as in the Goriacikin formula, [1].…”

In many cases, the influence of some of the characteristic parameters of some systems becomes important in relation to the influence of the other parameters, only when certain critical operating regimes are exceeded. These operating modes are often intangible in normal operation. In order not to endanger the system or to avoid the use of exaggerated power sources, the investigation of the influence of the parameters targeted in these critical operating regimes can be done by simulation, theoretical, experimental or mixed. The results are then subjected to a statistical analysis which may indicate a possible major change in the influence of some of the targeted parameters in the operation of the system. Specifically, the dynamic system considered is an agricultural machine for soil processing, consisting of a combinator and tractor. The simulation is done using a Goriacikin-type formula, which ensures complete theoretical control over the influence of the targeted parameters on the dynamic process of the machine. The parameters we focus on are working depth and working speed. The difference in intensity of the influence of each of the parameters is highlighted, trying an explanation for this difference. The explanations are useful for researchers who want to obtain information about the parameters whose influence on the functioning of the systems is small in the normal working regime but they can grow appreciably in the extra normal working regimes, even if for a short time.
