  • Patent number: 5957497
    Abstract: A device for steering a wheel assembly in a riding mower has a steering sprocket nonrotatably connected to a rotatable steering column and a transmission chain which is flexible in the plane of the steering sprocket and extends over the steering sprocket and forms, on both sides of the steering sprocket, a rectilinear chain run. Two deflecting wheels arranged on both sides of the steering sprocket are positioned in a deflecting wheel plane turned around the respective chain run lines relative to the plane of the steering sprocket. Each of two transmission chains, which extend over the respective deflecting wheels between the free end of the respective chain runs and the wheel assembly, is, between the steering sprocket and the respective deflecting wheels, coupled by way of a link element to the chain, which is flexible in the plane of the steering sprocket, so as to form a straight line with the chain.
