FOUR WHEEL STEERING MECHANISM A vehicle having a frame and front and rear pairs of wheels that are pivotal to steer the vehicle. A mower deck is operatively carried beneath the vehicle frame and between the front and rear pairs of wheels. A linkage mechanism operatively couples the front and rear pairs of wheels for transmitting pivotal motion therebetween. The linkage mechanism includes a first swing member swingably carried by the frame and coupled with the first rod member for swinging about a vertical axis as the front wheels pivot. A second rod member couples the first swing member with a second swing member that is carried by the frame for pivotal motion about a generally horizontal axis. A third rod member couples the second swing member with the rear pair of wheels. The longitudinal axis of the second rod and the pivot axes of the swing members are arranged at approximately ninety degrees to each other, and thereby provides clearance for other vehicle components located between the mower deck and the vehicle.
