PROBLEM TO BE SOLVED: To provide a pilot hydraulic system controller responding to the low pressure of the pilot hydraulic system. ;SOLUTION: The pilot hydraulic system controller comprises a pilot controller valve 20 for controlling flowing of hydraulic fluid for actuating first hydraulic system valve, a pilot controller lockout valve 40, and a detent control circuit 50 selectively supply power to a detent solenoid coil 64 connected to the pilot controller valve. The detent control circuit comprises a switch means 60 which selectively disables the detent solenoid coil when the pilot controller lockout valve is actuated to disable hydraulically the pilot controller, such that the detent solenoid coil will not operate the pilot controller valve when the pilot controller valve is hydraulically disabled.;COPYRIGHT: (C)1997,JPO
