This study examines the vibrations produced by mini tractor under different vibration isolation pad at different speed. A digital vibration meter VB-08201HA was used to measure vibrations generated by mini tractor. The vibration levels of tractor on plane surface of seat resting plate in X, Y, and Z directions were measured in acceleration (m/s2 ) at 1250, 1500 and 1750 rpm of tractor with the use of Thick ribbed natural rubber isolation pad (T-1), Thin ribbed natural rubber isolation pad (T-2), cork pad (T-3), thin ribbed natural rubber isolation pad with neoprene rubber sheet (T-4) and without anti vibration rubber pad (T-5). As per results, minimal level of vibration in longitudinal direction ( m/s2) was found by the use of thin ribbed natural rubber isolation pad with neoprene sheet. In lateral direction, maximum vibration reduction was found under thick ribbed natural rubber isolation pad ( m/s2 ). In vertical direction, minimum levels of vibration were found under cork pad ( m/s2 ). As per review of literature vertical vibrations are most sensitive to the operator. Therefore use of the cork pad for control of the vibration in the tractor seat is recommended.
