7. A work vehicle configured to include an engine mounted on a travelling machine body; an exhaust gas purification device arranged in an exhaust gas path of the engine; and a driving operation display device configured to display a driving operation situation of the travelling machine body and to be capable of executing regeneration control, in which particulate matter in the exhaust gas purification device is removed, comprising:
a regeneration switch configured to light up to prompt the regeneration control of the exhaust gas purification device to be executed,
a maneuvering column in which the driving operation display device is arranged in a control position and in which the regeneration switch is arranged outside the driving operation display device,
an engine controller configured to control drive of the engine, and
a driving operation display controller configured to control display operation of the driving operation display device,
wherein the controllers are electrically connected to each other, and
when a cumulative drive time of the engine has passed in a prescribed time or longer, a regeneration control request warning is displayed on the driving operation display device,
only when the regeneration switch is manually operated after display of the regeneration control request warning, the regeneration control of the exhaust gas purification device is started,
wherein the work vehicle is further configured so that when the driving operation display controller receives regeneration control request output of the engine controller, the driving operation display controller causes the driving operation display device to display the regeneration control request warning, thereby requesting a manual operation of the regeneration switch, and
wherein the regeneration switch is configured to start the regeneration control of the exhaust gas purification device when the regeneration switch is successively operated for a longer period of time than an operating time during which it can be determined whether an operation for the regeneration switch is based on the manual operation of an operator or based on operational errors.
