| The objective of this study was to evaluate the operating performance of crop residue cutting discs with distinct cutting edges in the no-tillage system, in relation to the travel speed of the tractor/tool holder set. The experiment was carried out in an experimental area, the soil classified as Paleudalf. The experiment consisted in a factorial arrangement of 4x4, totaling 16 combinations of treatments and three replications, composed by the interaction of the factors: crop residue cutting discs (plain flat disc, wavy disc, rippled disc, and helical wavy disc coulter) and travel speed (1.11; 1.67; 2.22 and 2.78 m s-1). It was used a mobile tool holder structure for the coupling of the active organs, which was pulled by a farm tractor. For the collection... |
