Furthermore, when the traveling locus of the harvesting machine 1 evaluated by the traveling evaluation unit 51 is divided into an actual work traveling locus and a non-working locus, an efficiency can be obtained by comparing and evaluating the actual working traveling locus or the non-working locus and fuel consumption. Can create an index for a typical work run. The distinction between work and non-work is determined, for example, by detecting the on / off state of a mowing clutch or the like.

  The device operation evaluation unit 54 statistically evaluates the number of operations and the operation time of the travel operation device 10A and the work operation device 10B based on the travel information and work information. This evaluation result serves as an index for determining whether traveling or work is efficient. Further, the number of operations and the operation time are accumulated in the database server 6 including past data, and such operation device maintenance data is derived. Operating equipment maintenance data is recorded for each work machine 1 and used for maintenance services by a maintenance company.

  The harvest evaluation unit 55 extracts the harvest information indicating the harvest amount and quality of the harvest from the work information sent from the work machine 1 and performs the statistical evaluation on the harvest amount and quality to obtain the harvest evaluation data.
