The present invention relates to an agricultural vehicle, which comprises: a storage tank which stores operating oil; a working machine line pump which is connected to the storage tank to supply the operating oil to a working machine; a working machine line which connects the working machine to the working machine line pump; a steering line pump which is connected to the storage tank to supply the operating oil to a steering unit; a steering line which connects the steering unit to the steering line pump; a drain line which has one side connected to the working machine line and the other side connected to the storage tank; a sequence valve which is provided in the drain line to selectively open and close the drain line; and a pilot line for the sequence valve, which connects the sequence valve to the steering line, and is connected to the working machine line downstream of the connection part between the drain line and the working machine line in the form of passing through the working machine line. When the working machine is not driven, the operating oil flowing through the working machine line is recovered to the storage tank via the drain line, thereby preventing the occurrence of heat and noise as the operating oil circulates through the working machine line.
