1. A system to detect grain loss of a harvester during harvesting operations, comprising:
a first pan and a second pan, the first pan magnetically supported on the harvester above a ground surface by a first electromagnet, the second pan magnetically supported on the harvester above the ground surface by a second electromagnet, the first electromagnet being electrically isolated from a power source while magnetically supporting the first pan on the harvester, the second electromagnet being electrically isolated from the power source while magnetically supporting the second pan on the harvester;
a signal controller arranged to generate a release signal when triggered by a user;
a signal receiver responsive to the generated release signal to electrically connect the first electromagnet with the power source and releasing the first pan to the ground surface while the second electromagnet remains electrically isolated from the power source and remaining magnetically supported on the combine harvester;
the signal receiver responsive to the generated release signal to electrically connect the second electromagnet with the power source and releasing the second pan to the ground surface.
