Tractors play an important role in Indian agriculture; it is used for agricultural operations and as a common means of transportation in rural areas. It exposes the drivers and workers sitting on fenders to whole body vibration. which results into back pain, spine degeneration and even spine disc problems. Keeping this in mind a study was carried out to measure the whole body vibration on driver and fender seat with fully loaded double axle tractor-trailer under different operating conditions. Vibration was measured on two terrains (Asphalt, Farm), at three speed (10, 12, 14 km/h on asphalt terrain and 4, 5, 7 km/h on farm terrain, as per ISO-5008 (1979)), in three directions (longitudinal, transverse, and vertical) using tri-axial accelerometers. Data was taken for 120 s each and analyzed using vibration meter and analyzer for three replications of each treatments. Vector sum of vibration and Health Guidance Caution Zone upper and lower limit were obtained for different operating conditions to know the health effect of vibration.
