More Information
Summary:A work vehicle includes a drive unit, a fan motor, a fan configured to be driven by the fan motor, an overrun state detecting unit configured to detect an overrun state of the drive unit, and a control unit. The control unit is configured to control a rotational speed of the fan to reach a first fan rotational speed by increasing the rotational speed of the fan when a detection value detected by the overrun state detecting unit becomes greater than or equal to a first threshold. The control unit is configured to control the rotational speed of the fan to reach a second fan rotational speed higher than the first fan rotational speed when the detection value becomes greater than or equal to a second threshold greater than the first threshold.
