The success of the establishment of a crop depends on several factors and the seeders press wheels should be capable to improve the contact soil-seed to promote good seed germination. The present work had as objective to study the influence of three models of press wheel, under different load levels on soil physical characteristic, in a projected sowing assay lane for this purpose. The experiment was carried in the municipal district of Uberaba, with, 3 blocks and four replications. The models of press wheels 1 and 2 presented better coefficients of correlation for the equations gotten in the diagrams pressure-deformation than the equation gotten with press wheel 3.
