PURPOSE:To prevent the danger of falling down and reduce the radius of turn by providing an Ackermann type steering function for either of front and rear wheels installed onto the chassis of an articulate type agricultural working car. CONSTITUTION:A chassis 1 is equipped with an articulate type steering function for the steering in bendable ways, in the horizontal direction, having the bendable part 4 of the chassis 1 as center. Rear wheels 3 are equipped with an Ackermann type steering function which can independently steer a rear axle 6. When the chassis 1 is turned by the articulate type steering function, front wheels 2 and rear wheels 3 are set so as to turn through a nearly equal locus around the turning center 0. Therefore, the radius of turn can be reduced, and the chassis does not turn easily. Front wheels 2 may be equipped with an Ackermann type steering function. |
