走行手段と、を設けたことを特徴とする、 作業車輌における制御装置。[Claims for Utility Model Registration] The actuator is configured to actuate one actuator in response to the operation of the speed change lever, disconnect and connect the main clutch, and operate the continuously variable transmission to the speed increasing side or the decelerating side. When an abnormal value is detected in the detection means that detects the operation angle of the gear shift lever or the amount of operation of the actuator, the alarm/cutoff means outputs an operation signal to the alarm buzzer and alarm lamp based on this, and also operates the actuator. The work vehicle is configured to output a signal and forcibly disconnect the main clutch, the vehicle comprising: a drive enable switch that switches the running body to a drive ready state; and when the drive enable switch is operated, the an alarm buzzer stop means for stopping an alarm buzzer; and based on the operation of the travel enable switch, the actuator, which has been operated to the fully stowed position by the alarm/disconnect means, is extended, the main clutch is connected, and the travel aircraft is moved. A control device for a work vehicle, comprising: a traveling means for traveling at a predetermined speed.
