A sensor system for actuating the lifting of a steerable axle of a wheeled vehicle includes at least one proximity switch mounted on a first structure of the wheeled vehicle and at least one magnet mounted on a second structure of the wheeled vehicle, wherein at least one of the first and second structures pivots relative to the other structure. When at least one of the first and second structures moves to a predetermined position relative to the other structure, the at least one proximity switch and the at least one magnet are aligned in close proximity, thereby activating the proximity switch to, in turn, actuate a lift mechanism for the steerable axle.
