“…This combination of factors dictates the operating posture, often resulting in prolonged periods of trunk rotation (Bottoms and Barber, 1978;Mehta and Tiwari, 2000). Vibration exposures within agriculture are also known to exceed the guidance for acceptable daily exposures (Sorainen et al, 1998).…”

We present a review of current expert opinion on the effects of combined exposures to trunk rotation and whole-body vibration, commonly experienced by operators of agricultural machinery. We evaluate the level of agreement between academic experts in the field of ergonomics, human response to whole-body vibration, and agricultural operators, on the effects of exposure to whole-body vibration (WBV) and trunk rotation. A total of 83 individuals responded to the paper-based questionnaire, that included questions on risk levels from individual and combined exposures, discomfort development, exposure duration limits and tasks within agriculture. The results showed that all groups considered exposure to WBV and trunk rotation as risk factors for the development of back pain. The experts were not in consensus regarding acceptable exposure durations, areas of discomfort experienced or recommendations for cab developments.Key Words: Agriculture; vibration; driving; trunk rotation; low back pain Practitioner summary: Trunk rotation combined with whole-body vibration are suggested causes for low back pain in exposed populations. The expert opinion on any possible interactions is explored through risk assessment models and recommendations for future practice. Designers should consider paying greater attention to operator's feedback on the machines they use, as this may include valuable insight to how to improve future developments.4

“…Although there are many epidemiologic studies reporting on acute injuries in agricultural populations [Lewis et al, 1998;Meyers, 1998;Lyman et al, 1999], few studies have investigated the relationships between cumulative exposure to physical stress and musculoskeletal disorders (MSDs). Because of the high physical strain associated with farming tasks, MSDs are common among farmers and agricultural workers [Nevala-Puranen et al, 1993Nevala-Puranen and Sorensen, 1997;Sorainen et al, 1998;Xiang et al, 1999]. Low back disorders are perhaps the most common MSD among farmers and agricultural workers [Xiang et al, 1999;Park et al, 2001].…”

“…Agricultural tasks that involved reaching overhead were considered a risk factor for shoulder disorders [Fulmer et al, 2002]. Whole-body vibration from tractor use has been associated with the risk of low back disorders [Sorainen et al, 1998]. Farmers involved with animal production showed a significant positive relationship with the risk of developing hip joint osteoarthritis [Thelin et al, 2004].…”

“…In addition, high fluctuations in the noise level can be identified depending on the specific type of work in progress, driver's skills, soil and weather conditions, different engine loads as well as vehicle speed. It is worth remembering that driving a tractor is associated with accompanying whole-body vibration (in old-generation tractors) which in synergistic influence with noise, can lead to damage to the vestibulocochlear organ [5][6][7][8][9]. Moreover, agricultural tractors are an important source of infrasound noise.…”

Introduction:The agricultural tractor is one of the most commonly used vehicles on farms and one of the most prominent sources of noise. This article presents an exemplary assessment of the audible and infrasonic noise levels in the cabins of selected modern wheeled agricultural tractors. Materials and Methods: Operator-perceived audible and infrasonic noise levels in the cabins were examined for 20 types of modern tractors during typical conditions of work. The tractors had been in use for no longer than 3 years, with rated power between 96 kW and 227 kW, designed and produced by world-renowned companies. Noise level measurements were performed in accordance with PN-EN ISO 9612:2011 (ISO 9612:2009. Results: Audible noise levels (A-weighted) ranged from 62.1 to 87.4 dB-A (average: 68.2 to 83.8 dB-A) for different work tasks. The factors influencing noise levels include performed tasks, soil, weather conditions and the skills of individual drivers. In spectrum analysis, the highest noise levels occurred at frequencies 250 Hz, 1 and 2 kHz. Infrasound noise levels (G-weighted) ranged from 87.3 to 111.3 dB-G. The driver-experienced exposure to infrasound was found to increase significantly when the vehicle was in motion. Conclusions: Average audible noise levels have no potential to adversely affect the hearing organ during tasks performed inside the closed cabins of the analysed modern agricultural tractors. Due to the relatively low audible noise levels inside the cabins of modern agricultural tractors, non-auditory effects are the only adverse symptoms that can develop. Modern agricultural tractors emit considerable infrasonic noise levels. All tractors introduced into the market should be subjected to tests with regard to infrasonic noise levels.
