PURPOSE:To provide easy operation of a differential lock device and eliminate the need for a differential locking pedal by actuating the differential lock device by means of a change-over valve which is controlled by a manually operated switch and makes a self-holding action. CONSTITUTION:Differential lock devices 15, 16 are driven by a change-over valve 22 and said valve 22 is actuated by a switch 24. Turning the switch 24 on makes a relay L hold by itself. The holding state of the relay L may be released by operating brake pedals 25, 26 or a handle 27. Since the self-holding feature of the relay L makes the change-over valve 22 maintain its operation, the differential locks may proceed with its action even if the switch 24 is released. |
