This work machine (1) is provided with a controller (20) that includes: a first memory unit (20MA) for storing work machine information (MI), the first memory unit (20MA) being enabled for rewriting the stored work machine information (MI); and a processor (20C) for collecting the work machine information (MI) and allowing at least one type of work machine information (MI) to be stored in the first memory unit (20MA) when trigger information is generated to start storage of the work machine information (MI) in the first memory unit (20MA). The controller (20) can externally vary the pre-trigger data number of the work machine information (MI) collected by the processor (20C) prior to the trigger information, and/or the post-trigger data number of the work machine information (MI) collected by the processor (20C) after the trigger information, and/or the time interval for collecting the work machine information (MI). |
