Abstract
A work vehicle includes a monitoring device which monitors the surroundings of the work vehicle; an alarm device which outputs an alarm on the basis of a monitoring result of the monitoring device; a posture detection unit which detects whether an operator sits on an operation seat of the work vehicle and is in an operation posture for operating the work vehicle; and a control unit which controls the alarm device on the basis of the result of detection by the posture detection unit. Based on detection by the posture detection unit that the operator is in the operation posture, the control unit causes the alarm device to output an alarm based on the monitoring result of the monitoring device, and based on detection by the posture detection unit that the operation posture of the operator is released, the control unit causes the alarm device to stop outputting the alarm based on the monitoring result of the monitoring device.
