Trying to relate the soil tillage methods with some of their effects in Haplustox, it was installed in the municipal district of Uberaba/MG, a research using a completely randomized experimental design in factorial array with five treatments and four replications. The treatments were composed by the soil tillage: chisel plow, rotary tiller, moldboard plow, disk harrow and disk plow. They were appraised: soil mobilized area, elevation area, medium thickness of the mobilized layer, roughness index and the alteration of the roughness of the soil. It was verified that the chisel plow provided larger roughness index of the soil being framed in the conservationist method disaggregating less the soil, collaborating with the smallest soil losses for erosion.
