Objetivou-se, com este trabalho, analisar o desempenho operacional de semeadora-adubadora Marchesan Cop Suprema, equipada com quatro fileiras, com espa&ccedil;amento 0,90 m, em fun&ccedil;&atilde;o de tr&ecirc;s tipos de preparo do solo: convencional (ara&ccedil;&atilde;o e duas gradagens), reduzido (escarifica&ccedil;&atilde;o com rolo destorroador) e semeadura direta, em &aacute;rea anteriormente semeada com milho (<em>Zea mays</em> L.), em dois espa&ccedil;amentos (0,90 m e 0,45 m). Os resultados indicam que a exig&ecirc;ncia de pot&ecirc;ncia, for&ccedil;a de tra&ccedil;&atilde;o e rota&ccedil;&atilde;o do motor, na opera&ccedil;&atilde;o de semeadura, n&atilde;o foram influenciadas pelo preparo do solo e cultivo do milho. A patinagem dos rodados do trator apresentou diferen&ccedil;as, sendo menor na semeadura direta e maior no preparo convencional e reduzido. </span></span></span></p> <p style="margin-bottom: 0cm; font-style: normal; font-weight: normal; line-height: 120%; text-decoration: none;" lang="pt-BR" align="JUSTIFY"><span style="color: #000000;"><span style="font-family: Times New Roman,serif;"><span style="font-size: small;">PALAVRAS-CHAVE: <em>Zea mays</em> L.; semeadura; capacidade operacional; patinagem; m&aacute;quinas agr&iacute;colas.</span></span></span></p>
