Abstract
By accurately detecting defects in the control valve, we provide a work vehicle with high operational efficiency. [Solution] A work vehicle comprising a machine body, a hydraulic actuator supported by the machine body, a control valve that controls the supply of hydraulic fluid to the hydraulic actuator, a control device that controls the control valve, and a state detection sensor that detects the state of the hydraulic actuator. The control device determines a malfunction of the control valve based on the deviation value, which is the difference between the measured value output from the state detection sensor and the target value of the hydraulic actuator.
