Agricultural tractor operators are frequently exposed to intense vibrations, especially during tillage operations, which can lead to discomfort, fatigue, and long-term health issues. This research presents an integrated approach to improve operator ride comfort through a combination of advanced suspension and seat technologies. By developing and validating a dynamic model of a tractor-implement system, and by employing intelligent controllers—namely, PID and fuzzy logic-based strategies—this study evaluates their effectiveness in reducing vibrations. The passive suspension system is replaced with a semi-active MR (magnetorheological) damper, tuned via real-time control algorithms. Both simulation and experimental results show that the fuzzy-controlled MR seat significantly reduces root mean square (RMS) acceleration values, offering up to 78% improvement in comfort over traditional systems. The outcomes suggest that this integrated control and hardware modification strategy can serve as a foundation for next-generation agricultural vehicles prioritizing ergonomics and operator well-being.
