Abstract: A vehicle is provided having a horizontal frame with two associated front wheels and two associated rear wheels wherein at least one set of associated wheels is rotatable about vertical axes by steering means. A cross shaft is mounted on the frame and rotatable about its axis in response to a steering input of an operator. A first shaft arm defining a first pivot is rotatable with the cross shaft, and a second shaft arm defining a second pivot is rotatable with the cross shaft. The second pivot has a radial spacing from the shaft axis equal to the radial spacing of the first pivot from the cross shaft, and the pivots are substantially symmetrical on opposite sides of a horizontal plane when the steering mechanism is in a neutral position. First and second steering arms are pivotable about the vertical pivot axes of the set of associated wheels to turn the wheels, and the steering arms define third and fourth pivots located on opposite sides of their associated vertical axes.
