Abstract
An articulated work vehicle has front and rear frames coupled. The work vehicle includes a hydraulic actuator driven by hydraulic pressure to change a vehicle body frame angle of the front frame with respect to the rear frame, a lever rotatable to change the body frame angle, a control valve that controls a flow rate of oil supplied to the hydraulic actuator, and a controller. The controller sets a target angle of the vehicle body frame angle with respect to an input angle of the lever, and controls the control valve such that an actual angle of the vehicle body frame angle matches the target angle of the vehicle body frame angle.
