A seat suspension system includes a rigid support plate angled downwardly and pivoted to a supporting vehicle at the plate's forward end. A bucket seat is connected to the plate by hand screws that extend through slots in the plate to provide leg room adjustment. One end of the coil spring is adjustably attached to the seat support plate by a connector extending through a slot in the plate to provide forward and rearward adjustment, independent of the seat adjustment, thereby comfortably supporting operators of different heights and weights between about 100 and 400 pounds. A safety interlock switch prevents operation of the tractor unless an operator is in the seat, and a latch is provided to latch the seat in an inclined position when the tractor is not in use.
