1. An agricultural system for determining crop loss of an agricultural harvester, the agricultural system comprising:
a support beam extending along a lateral direction between a first lateral end and a second lateral end of the support beam, the support beam being positioned at a material-other-than-grain (MOG) outlet of the agricultural harvester;
one or more impact sensors supported on the support beam, the one or more impact sensors comprising a first impact sensor supported on the support beam proximate the first lateral end of the support beam and a second impact sensor supported on the support beam proximate the second lateral end of the support beam, the second impact sensor being spaced apart from the first impact sensor along the lateral direction, each of the one or more impact sensors being at least one of a vibration sensor or an acoustic sensor, each of the one or more impact sensors generating data indicative of a magnitude of vibrations of the support beam in response to each crop impact of a plurality of crop impacts on the support beam between the first and second lateral ends, the magnitude of the vibrations of the support beam being indicative of a crop impact location of each crop impact of the plurality of crop impacts on the support beam between the first and second lateral ends, the plurality of crop impacts being caused by crop leaving the agricultural harvester through the MOG outlet; and
a computing system communicatively coupled to the one or more impact sensors, the computing system determining the crop impact location of each crop impact of the plurality of crop impacts on the support beam between the first and second lateral ends based at least in part on a comparison of the data from the first and second one or mere impact sensors.
