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 (2.49 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 (2.93 m/s2). In vertical direction, minimum levels of vibration were found under cork pad (6.52 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.
