Working device diagnostic system, agricultural machine, agricultural work support system

Abstract

A working implement diagnostic system includes a weight sensor to detect the weight of a working implement connected to a traveling machine body of an agricultural machine that travels in an agricultural field, and a controller configured or programmed to diagnose the working implement based on a change in the weight of the working implement. An agricultural machine includes a working implement diagnostic system, a traveling machine body, and a connector to connect a working implement to the traveling machine body. An agricultural work support system includes the working implement diagnostic system, an agricultural machine, and a management server including a database accessible from outside. The agricultural machine further includes a communicator to wirelessly communicate with the management server. The controller transmits a result of diagnosing the working implement to the management server via the communicator. The management server receives the diagnosis result and stores the diagnosis result in the database.
