Zusammenfassung:The manufacture of agricultural machinery should follow the criteria that specify the existence and standardization of components and security systems, so as to make them safe. The aim of this study was to establish a checklist to classify agricultural tractors according to a safety index. The list was obtained through literature review and by checking norms and articles on Components and Security Systems (CSSs) that must be present on tractors in order to provide proper security. These CSS were grouped to form a checklist obtained by the Mudge diagram, whose function was to pair CSSs according to their relevance in order to organize them hierarchically. Subsequently, a spreadsheet with weighted CSSs was applied to 31 tractor models of 5 different brands, enabling the determination of their safety ratings by the addition of values of each CSS. A CSS checklist allowed obtaining a safety index listing tractors by the level of safety offered by each of them, thus enabling the tractor buyer to choose the one that offers lower risk of accidents in its use. Keywords: risk of accidents, mechanized farming, Mudge diagram. A fabricacao de maquinas agricolas deve obedecer as normas que especificam a existencia e padronizacao de componentes e sistemas de seguranca. No entanto, as marcas e modelos de tratores nao possuem os mesmos componentes e sistemas de seguranca em seus produtos. Sendo assim, o objetivo deste trabalho foi estabelecer uma lista de verificacao para classificar os tratores agricolas de acordo com um indice de seguranca. A lista foi obtida levantando-se os Componentes e Sistemas de Seguranca (CSS's), que devem estar presentes nos tratores agricolas. Estes CSS's foram agrupados em ordem crescente de importancia formando uma lista de verificacao, obtida por meio do diagrama de Mudge, cuja funcao e relacionar aos pares os CSS's, a fim de hierarquiza-los. Apos a planilha com os CSS's ponderados foi aplicada a lista de verificacao a 31 modelos de tratores agricolas de cinco diferentes marcas, possibilitando o estabelecimento dos seus indices de seguranca, por meio do somatorio dos valores de cada CSS' presente. A lista de verificacao dos CSS's permitiu a obtencao de um indice de seguranca, que relaciona os tratores, em funcao do grau de seguranca que cada um oferece, possibilitando ao responsavel pela selecao do trator a escolha daquele que possua menores riscos de acidentes na sua utilizacao.
