Various authors, establish that soil compaction is considered the greatest environmental problem caused by conventional agriculture, it is the type of degradation that is most difficult to locate and understand, because it shows no obvious marks on the ground surface. To know the intensity of the passes and their effect on the compaction or cone index of the tractor machine assembly during the agricultural cycle of corn, with the conventional and minimum tillage technologies, each tractor was equipped with a DGPS signal receiver when entering to the cultivation field, to monitor traffic in all tasks, and the data were recorded with a frequency of 2 s. The width of the tires was measured by observing the footprint reflected on the ground with an air pressure of 140 kPa. In traditional tillage with disc plows 91.15% was covered and in total it was 384.83% of the surface. In the minimum tillage technology with the multi-plow 36.95% was covered and in total it was 170.08%. Being ostensibly less in this technology than in traditional tillage. Regarding the cone index (Ic) in tillage with disc plows after sowing, the Ic exceeded 3 MPa after the depth of 12.5 cm, while with multi-plow, 80% of the data is below them. 3 MPa, coinciding with the Ic after harvest in both cases.
