Abstract
A guide rod assembly is mounted on the front end of a tractor with the guide rods closely adjacent the front wheels and the crop rows to transmit steering signals to a steering guidance system. The pair of guide rods pivot from a downwardly extending parallel position upwardly toward a raised closed collapsed transport position. When the guide rods reach a horizontal position, continued upward movement by the lift arms cause the guide rods to pivot inwardly toward each other to a collapsed transport position eliminating interference with the steerable tractor front wheels.
