This work addresses the design and experimental evaluation of a passive suspension system on the handlebar of a two-wheel tractor to reduce vibrations affecting the hand-arm-shoulder of the farmer. The existing handlebar element is analyzed and evaluated via numerical and experimental modal analysis to determine a proper passive suspension system based on gas shock absorbers attached on both sides of the main base of the handlebar support. Finally, the dynamic response of the proposed low-cost suspension system is evaluated by means of experimental modal analysis to quantify the overall damping injection with the proposed solution.
