Abstract
A steering system for a four-wheeled vehicle which can rotate the front steering wheels unequally as the vehicle is turning in order to prevent excessive tire scuffing and which can provide a zero turning radius of the vehicle about its inside rear wheel. The two front steering wheels each has its own vertical pivot post. Standard roller chains are trained around eccentric sprockets mounted on the pivot posts and a drive sprocket which is rotatable by a manually operable steering member. Positive chain tauteners maintain the chains taut as the distance from the eccentric sprockets to the drive sprocket varies during turning.
