PURPOSE:To make the four-wheel steering practicable through a simple mechanism by enabling the direction of steering of the front and rear wheels to be decided automatically according to the changing-over position of a select lever. CONSTITUTION:A change lever (G) is linked to hydraulic cylinders (I) for steering the front and rear wheels (A). The hydraulic cylinders are operated in such a manner that, when a select lever (G) is in the low position, the front wheel and the rear wheel are steered in the opposite direction, and then, when the select lever is in the second position, the front wheel and the rear wheel are steered in the same direction, and further, when the select lever is in the drive-third position, the rear wheel is fixed as it keeps straight on. |
