<P>PROBLEM TO BE SOLVED: To provide an antitheft device for a working vehicle having a high antitheft effect. <P>SOLUTION: The antitheft device for a working vehicle includes: a setting means 91, which sets an antitheft mode; operation detection means 85, 86, which detect the operation of outriggers; and a control means 90, which, when the antitheft mode is set and the operation detection means 85, 86 detect the operation of the outriggers 24, 25, changes over at least one of changeover control valves 51-54 for a working device to a position other than a neutral position III. The supply of pressure oil to the changeover control valves 55, 56 for the outriggers is cut off, so that hydraulic actuators 38, 39 for the outriggers cannot be operated. The outriggers 24, 25 can be maintained in a grounded state and the working vehicle 1 can be maintained in a state of being unable to run, so that a theft by making the working vehicle 1 run can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
