A hydraulic device has a first pump, a second pump, an operating state detector configured and arranged to detect an operating state, a connection switching unit configured and arranged to selectively connect the second pump to either a first hydraulic oil line or a second hydraulic oil line, and a switching controller configured to control, based on the operating state detected by the operating state detector, a switching operation of the connection switching unit. The switching controller is further configured to inhibit the switching operation of the connection of the second pump when the detected operating state is such that at least one of clutches of a multi-stage transmission and a steering device is in a state transition or at least one brake of the steering device is being operated. |
