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... |

Contact with tractor moving parts is one of the most frequent causes of accidents with agricultural machinery. Thus, the present study aims to verify the presence of PTO master shield and its dimensional specification, in new Brazilian agricultural tractors, according to ABNT NBR ISO 500-1 (2016) standard. Was evaluated 43 agricultural wheeled tractors models, with power above 36,8 kW, distributed in seven dealers located in Santa Maria, RS. Data collection was based on the visual verification of the presence or absence of PTO master shield (NR 31, 2013), as well as it dimensional variables (ABNT NBR ISO 500-1, 2016) verified through the use of measuring tape. Regarding the presence, 100% of the analyzed models contained the PTO master shield. Regarding... |

O processo de semeadura representa um dos mais importantes fatores que podem contribuir para o estabelecimento de uma cultura. Além disso, visando proteger as sementes e plântulas em seus estádios iniciais, tornou-se comum o tratamento fitossanitário na pré-semeadura,que pode alterar a rugosidade e o coeficiente de atrito das sementes com os mecanismos das semeadoras. Assim, avaliou-se a distribuição longitudinal de sementes de soja com diferentes tratamentos fitossanitários em diferentes densidades de semeadura. Através de um delineamento bifatorial (4x4), avaliou-se os espaçamentos aceitáveis, múltiplos e falhos, conforme as normas da ABNT, e determinou-se também a acurácia e precisão da distribuição de sementes em quatro modalidades de tratamento (SP,... |
