摘要： A work vehicle steering control apparatus comprises a vehicle body (11), front wheels and rear wheels both of which can be steered respectively; a front-wheel steering cylinder (92) and a rear-wheel steering cylinder (94); a steering dial (72); a steering actuation controller (50); and a steering angle detector. The steering actuation controller (50) is configured in a manner such that when a steering operation is performed, and when the steering angles of one set of wheels are less than a predetermined angle (θ1), the controller (50) controls the steering actuator to steer only the one set of wheels in response to the directional-change steering operation. When the steering angles of the one set of wheels are equal to or more than the predetermined angle, the controller (50) controls the steering actuator to steer the other set of wheels in a direction opposite to steering direction.
