A seat suspension mechanism providing a vertical range of cushion travel to a tractor seat when fluid is supplied to the mechanism. The suspension mechanism includes a linkage assembly movable through a predetermined path of travel for securing the seat to the frame and a damper assembly operable in combination with the linkage assembly for regulating the cushion travel of the seat. The present invention further includes an automatic seat stop mechanism connectable to the suspension mechanism for limiting the movement of the linkage assembly and the seat upon cessation or interruption of fluid flow to the seat suspension mechanism.
