The topic of the paper is the analysis of the use of semi-active cabin suspension for agricultural vehicle. A magnetorheological damper is located in the cabin suspension with the aim of improving the comfort perceived by passengers. The entire control system design is outlined, with a focus on the experimental activity. An analysis of the suspension performances without control is proposed in order to highlight the potential trade-off of the system. The control of damping may overcome this trade-off as experimentally evaluated.
