The aim of this study was the identification of accident scenarios and causes by analysing existing accident reports of recognized agricultural occupational accidents with tractors, self-propelled harvesting machinery and materials handling machinery from 2008 to 2010. As a result of a literature-based evaluation of past accident analyses, the narrative text analysis was chosen as an appropriat...

Recently, the issue of machine condition monitoring and fault diagnosis as a part of maintenance system became global due to the potential advantages to be gained from reduced maintenance costs, improved productivity and increased machine availability. The aim of this work is to investigate the effectiveness of a new fault diagnosis method based on power spectral density (PSD) of vibration sign...

Agricultural work injury data are less available than data for other industries, so an overview of existing data is provided. Agriculture has the highest annual work death rate of all industries, 52 per 100,000 workers, which is five times the combined rate for all industries. Tractor-related injuries are the leading types of fatal injuries; injuries involving agricultural machinery, animals, a...

The conventional load-sensitive hydraulic drive chassis system for agricultural machinery uses a combination of engine and pump, which cannot adjust the control strategy according to working conditions. It does not meet current trend energy-saving emission reduction. To this end, an electro-hydraulic machinery, permanent magnet synchronous motor quantitative is proposed. A variable LS different...

Nearly all modern off-road agricultural machinery are powered by petroleum, primarily diesel fuel. Equipment manufacturers work to improve fuel efficiency of their equipment to provide better value to their customers. Benefits of reducing petroleum use include lower operating costs, improved operational efficiency, improved energy security, and environmental benefits. Agricultural tractor testi...

Statistics on the machinery performance are essential for farm managers to make better decisions. In this paper, the performance of all machineries in five sequential operations, namely bed forming, stone separation, planting, spraying and harvesting in the potato production system, were investigated during one growing season. In order to analyse and decompose the recorded GPS data into various...

Testing agricultural operations and management practices associated with different machinery, systems and planning approaches can be both costly and time-consuming. Computer simulations of such systems are used for development and testing; however, to gain the experience of real-world performance, an intermediate step between simulation and full-scale testing should be included. In this paper, ...
