Sugar cane harvester having an arrangement for steering the crop dividers and topper mechanism together with the wheels

A self-propelled chopper cane harvester is equipped with a front frame section including opposite sides which are each mounted for pivoting about a respective upright pivot axis. Respectively mounted to the opposite sides of the front frame section are front wheels and row dividers. A steering cylinder is mounted for pivoting the frames to opposite sides of a straight ahead position to thereby effect steering of the front wheels. A topper mechanism is mounted so as to pivot or turn in response to the steering of the harvester.
