Work vehicle and abnormality notification method for work vehicle

A work vehicle comprising:

• travelling work state detection sensors to detect a travelling work state of the work vehicle to output detected signals indicating the traveling work state;
• a first calculator to calculate a position of the work vehicle based on positioning data;
• a first processor to determine that an early abnormality occurs when the detected signals satisfy a first condition, the work vehicle being in an early stage of trouble in travelling due to the early abnormality;
• a second processor to determine that an actual abnormality occurs when the detected signals satisfy a second condition which has a second threshold severer than a first threshold of the first condition, the work vehicle being in trouble in travelling due to the actual abnormality;
• an information generator to generate abnormality information including at least one of the early abnormality and the actual abnormality and including an abnormality occurring position of the work vehicle where the at least one of the early abnormality and the actual abnormality occurs;
• a first notifier to provide a notification of the early abnormality toward an outside of the work vehicle when it is determined that the early abnormality occurs;
• and
• a second notifier to provide a notification of the actual abnormality toward the outside of the work vehicle when it is determined that the actual abnormality occurs.
