Moving tractors and mobile systems around the soil results in excessive compaction, causing multiple negative consequences. The results of the influence of the running mechanism of tractors and mobile systems on changes in soil compaction and cone resistance at penetration at a depth of 0-35 cm in sunflower production are presented in the paper. The resistance to cone penetration into the soil was measured on the track and between the tracks of the tractor wheels and the mobile systems in the inner part of the parcel and at headlands in the germinating and harvest stages of sunflower, by the Eijkelkamp pentrologer. Combining the possibilities according to given criteria, the results were obtained based on which we used numerical interpolation and created eight topographic maps showing penetration resistance in eight characteristic cases. The obtained results indicate that at a depth of 0-5 cm in the sunflower germinating phase by 32.86% the soil compaction was less between the tracks than in the track of the tractor wheels, while at a depth of 30-35 cm the compaction was less by 22.53%. In the harvest phase at 0-5 cm of depth between the wheels the compaction was less by 14% than in the track of the wheels of tractors and mobile systems, while at 30-35 cm the difference was 21.53%. Similar differences in soil compaction were observed in the other variants tested.
