Patent ID: 8880302

Claim:
A working vehicle: a hydraulic actuator; an operating member configured to operate the hydraulic actuator; a pilot valve configured to output pilot pressure in conformance with operation of the operating member; an actuator control valve configured to control the hydraulic actuator in conformance with the pilot pressure input thereto; a lock member configured to be switched between a lock position and a release position; an operation console configured to move together with the lock member, the operation console supporting the operating member and the lock member; a lock valve configured to be switched between a release condition in which a supply of pilot pressure to the actuator control valve is allowed, and a lock condition in which supply of pilot pressure to the actuator control valve is shut off; a lock valve switching unit configured to switch the lock valve from the lock condition to the release condition when the lock member switches from the lock position to the release position; an elapsed time detection unit configured to detect an elapsed time from when the lock member switched from the lock position to the release position; a first time determination unit configured to determine whether or not the elapsed time is greater than or equal to a first predetermined time; a pilot pressure determination unit configured to determine whether or not the pilot pressure is greater than or equal to a predetermined pressure; a second time determination unit configured to determine whether or not a continuous time duration during which the pilot pressure is greater than or equal to the predetermined pressure is less than or equal to a second predetermined time; and an error operation monitoring unit configured to allow switching over of the lock valve by the lock valve switching unit, in a case that the pilot pressure becomes greater than or equal to the predetermined pressure when the elapsed time is greater than or equal to the first predetermined time, the error operation monitoring unit being configured to switch the lock valve to the lock condition in a case that the pilot pressure becomes greater than or equal to the predetermined pressure and the continuous time duration is greater than the second predetermined time when the elapsed time is less than the first predetermined time, and the error operation monitoring unit being configured to allow switching over of the lock valve by the lock valve switching unit in a case that the pilot pressure becomes greater than or equal to the predetermined pressure and the continuous time duration is less than or equal to the second predetermined time when the elapsed time is less than the first predetermined time.
