“…Additionally, is important to highlight the accidents majority happened in daytime period, bearing in mind in Brazil the sun rises at 6a.m and sets at 6 pm, which has not influenced operator's visibility. Macedo (2015) argues that the bulk of incidents' events happen in both the afternoon and the morning, in this sequence, highlighting the crashes that happen when the operators' shift is almost finished, event usually due tiredness. The weather conditions at the moment the episode happened is illustrated in Figure 5.…”

Minas Gerais state has the largest road network within Brazil on which thousands of vehicles travel daily. Due the increasing in the number of tractors in Brazil, traffic incidents may have also increased. Therefore, the present work aimed to characterize accidents involving tractors in Minas Gerais federal highways through the following indicators, event type, crash causes, time of the day in which the episode occurred, drivers age, climatic conditions and the road the case happened by analyzing Traffic Accident Reports (TAR). The incidents' information was provided by the Federal Highway Police (FHP) through TAR questionnaires. The total data set in the present work is composed by 148 TAR forms in Minas Gerais State between January, 2008 and September, 2011. The results were submitted to the chisquare test at 95% probability. The events' profile indicates collision as the main crash type, lack of attention as the main cause and the time period that has the most occurrences was 09:00 to 11:59 time period. Additionally, the group aged 25 to 30 years old were involved in the highest number of episodes, in good climatic conditions and the Brazilian Federal road BR-381 had the most evidenced cases.

“…Apesar de concebidos como força de trabalho e projetados para a operação em atividades agrícolas, essas máquinas necessitam realizar deslocamentos de uma área para outra, fazendo o uso não só de estradas da propriedade, como também de vias públicas [7][8][9][10][11][12][13]. Entretanto, quando os tratores agrícolas trafegam nessas vias, caracterizam-se como veículos lentos por trafegarem, geralmente, a uma velocidade entre 15 km.h -1 e 20 km.h -1 , muito inferior à velocidade atingida por outros veículos [9]. No Brasil, onde não existe sinalização regulamentadora, a velocidade máxima das vias urbanas varia de 30 km.h-1, em vias locais; a 80 km.h-1, em vias de trânsito rápido.…”

O crescente uso de máquinas agrícolas, especialmente de tratores, na busca pela ampliação da superfície dominável, intensificou também a propensão a acidentes com essas máquinas. Assim, o objetivo desse estudo foi calcular a evolução da quantidade de veículos por quilômetro das rodovias brasileiras, no período de 1970 a 2015 e inter-relacionar com os dados de acidentes envolvendo tratores agrícolas, nas vias públicas. Para esse estudo foi considerada a frota brasileira de veículos convencionais e de tratores nesse período de 45 anos (1970-2015), bem como a extensão em quilômetros, de rodovias brasileiras. No último ano analisado (2015), foi observado um total de mais de 1,72 milhões de quilômetros de vias e 43,5 milhões de unidades de veículos em circulação. Se comparado aos 1,13 milhões de quilômetros e 2,5 milhões de veículos, em 1970, o crescimento de 52,21% e 16,8 vezes, respectivamente, demonstram a acentuada intensificação do tráfego. Em concomitante, também se elevou a circulação de tratores em vias públicas, o que aliado a velocidade das vias, bem como o tipo e a largura das mesmas, elevaram, por sua vez, a ocorrência de acidentes. Dentre os acidentes, as colisões traseiras em tratores são destaque, com maiores índices evidenciados. Apesar do número de acidentes ser menor, a gravidade dos mesmos apresenta de 5 a 8 vezes mais fatalidades, em comparação aos acidentes com veículos. Assim, a evolução se apresentou positiva, com acréscimo na intensificação do tráfego nas rodovias brasileiras, porém como consequência, há a elevação, também, da ocorrência de acidentes com tratores nesta condição.

“…The agricultural tractor is the most important source of power in the agricultural environment, contributing to the development and technological advancement of the Agricultural Production Systems (APS), as the only way to guarantee the gains of scale that are observed in the global Agribusiness. However, the tractor is also a source of risk of accidents and injuries to workers (Schlosser et al, 2002, Hoy, 2009, Macedo et al, 2015, Casazza et al, 2016, Lleras et al, 2016. Springfeldt (1996) and Khorsandi et al 2017 reported that within accidents involving agricultural tractors the primary cause is tractor rollover, Murphy & Yoder (1998) mention that rollover accounts for a third of total fatalities involving agricultural workers.…”

Studies conducted by the international labor organization have shown that operations involving agricultural machinery are among the three activities with the highest risk of accidents to workers. Among the possible causes, rollover is the most common, accounting for 33% of fatal accidents. Despite this, there are standards that provide for the use of safety devices to ensure the physical integrity of the operator, among these equipment stand out rollover protection structures, which can be foldable or not. In this sense, the objective of this study was to perform an ergonomic study in order to analyze the torque required for lowering and lifting a foldable rollover protection structure attached to an agricultural tractor, developing instrumentation for validation of the efforts required to operate the structure and comparing the results obtained with the values recommended by the Standard (CODE 6-OECD). When torque values were above those recommended by the standard, a set of torsion springs was used as solution to torque reduction. After further testing, the effectiveness of the solution was verified. Furthermore, it was observed that the angular speed of the bar does not have a significant influence on the torque required to lift the bar.
