Abstract: O terraceamento com arados de discos ainda é prática comum em pequenas propriedades rurais, munidas de implementos e tratores de menor porte. O objetivo do trabalho foi avaliar o desempenho operacional e econômico de diferentes modelos de arados de discos comumente usados na construção de terraços em pequenas propriedades rurais. O experimento foi realizado com arados de discos e tratores em três pequenas propriedades rurais nos municípios de Botucatu-SP e Avaré-SP. O delineamento experimental utilizado foi o … Show more

“…The lowest Operating Cost in the construction of the terraces was obtained by the drag plow, followed by the reversible plow and the fixed plow. The values obtained by the reversible and fixed plows corroborate the results found by Correia et al (2018) who concluded that, regardless of the number of discs, the reversible plows provided greater operational efficiency and effective field capacity.…”
