  Ergonomic Assessment of Self-Propelled Machinery Seats for Agricultural Workers
  Author(s): Gajendra Singh*, VK Tewari, Smrutilipi Hota and Chanchal Gupta
  
  Excessive vibrations in self-propelled machinery engaged in agricultural farm operations cause mechanical failures and subject the operators to discomfort. Laboratory tests were carried out in a completely randomized design in a factorial arrangement (type of seat×engine, speeds×subject) with a view to evaluate the self-propelled machinery seat ergonomically. Various performance parameters like 1/3rd octave band vibration acceleration, Working Heart Rate (WHR), Oxygen Consumption Rate (OCR), Energy Expenditure Rate (EER) were measured during the operation of self-propelled machinery with different types of seats (SM-1 to SM-5) and statistically analyzed. The 1/3rd octave band vibration acceleration of self-propelled machinery was found to be lowest with SM-5 seat i.e. 0.983, 0.646, 1.019 m/sec2 and highest with SM-1 seat i.e. 4.21, 2.77 and 9...
