Sažetak

The difference in draft force is analyzed for six different passes during longitudinal plowing of the plot. The force is measured indirectly using four strain transducers. Values of the force are obtained by calculation after previous calibration and then measurements in the experimental field. The strain readings on the sensors installed on the outside of the tractor lower links are used. Similar values are obtained on the other two sensors installed on the inside of the links. The biggest difference is observed between the first and second pass, respectively, the second and third one for which the value of effect size amounts to 0,824 and 0,835 respectively. The study highlights draft force in the function of soil resistance as an exceptionally important parameter in the analysis of agricultural soil and suggests the expansion of current routine in precision agriculture mapping.
