Users of agricultural tractors are exposed to high level of vibration and working more than the allowable time which causes damaging different part of the body and consequently decreasing efficiency and quality of work. This book helps to evaluate the performance of different subsoilers working at different depths and also quantify the effect of the tractor-subsoiler system on tractor ride vibration. The book provides the comparison of vibration data with the ISO standard permissible limits to find safe limiting working hours. Documentation /database of different subsoilers' performance helps to work-out the schedule of safe/harmful exposure limits determination.
