Abstract

An articulated work vehicle includes a hydraulic actuator, a control valve, a joystick lever, and a first link mechanism. A front frame is linked to a rear frame. The hydraulic actuator is configured to be driven by hydraulic pressure and configured to change a steering angle of the front frame with respect to the rear frame. The control valve is configured to control flow of fluid supplied to the hydraulic actuator. The joystick lever is disposed in a cab provided on the rear frame. The joystick lever is configured to be operated by an operator. The first link mechanism is disposed below the cab. The first link mechanism is configured to transmit an operation of the joystick lever to the control valve.
