Descrição: dc.descriptionThis work had as objective to evaluate the performance of mechanisms of cutting of the no-tillage seedrills in different vegetable coverings and applied vertical loads. The experimental design used was in randomized blocks and factorial scheme 3 × 4, with four replications. The trials were accomplished with three different mechanisms of culting of the straw (plane disc, corrugated disc and wavy disc), using four different vertical loads (750, 1500, 2250 and 3000 N). All treatments were accomplished in five straw coverings (corn, sorghum, triticale, black oats and radish). The results showed that larger the amount of dry matter covering the soil, higher the demand of horizontal and vertical forces. The wavy disc promotes the largest values of area of mobilized soil and requires large horizontal force, vertical force and horizontal force per area of cutting depth of discs (specific force). The treatment with plane disc required higher values of the horizontal forces per area of mobilized soil and of vertical force in the corn and sorghum coverings.-
