The present invention relates to a hydraulic steering device for an agricultural vehicle. The hydraulic steering device comprises a steering pump, an automatic steering unit, a manual steering unit, a manual changing unit, an automatic blocking unit and an automatic maintaining unit to control the automatic blocking unit. The manual changing unit blocks passage of the working fluid supplied from the steering pump when the automatic steering is performed in a state in which the manual steering is not performed and causes the working fluid supplied from the steering pump to pass in both cases when the automatic steering is not performed in the state in which the manual steering is not performed and when the manual steering is performed. The manual steering unit changes the traveling direction of the agricultural vehicle using the working fluid supplied from the steering pump when the manual steering is performed.
