<P>PROBLEM TO BE SOLVED: To provide an exhaust gas post-treatment device of a working vehicle capable of properly performing control concerning exhaust emission control such as reducing agent injection control and warning control in the exhaust gas regulated area , and in the exhaust gas unregulated in which the precursor of the reducing agent such as an urea aqueous solution is difficult, stopping the control and enabling an operator to perform comfortable work, even if the working vehicle comes and goes between an exhaust gas regulated area and an exhaust gas unregulated area. <P>SOLUTION: When the hydraulic shovel vehicle is moved to the exhaust gas unregulated area, a controller 42 determines that the vehicle body is in the exhaust gas unregulated area, makes urea water injection control inoperative, brings an engine and a hydraulic system in normal operation, and turns off monitor warning, based on position information detected by a GPS device 43. <P>COPYRIGHT: (C)2009,JPO&INPIT |
