AI summary

An agricultural machine for reducing harvesting loss during a harvesting operation includes: front ground engaging mechanisms coupled to a front axle, a chassis supported above the ground by the front ground engaging mechanisms, a cutting head located forward of the front ground engaging mechanisms and configured to harvest crop in a worksite, an image sensor, and a controller operatively coupled to the image sensor. The image sensor captures images of a field of view, which includes an area rearward of the front axle. The controller receives data corresponding to the images from the image sensor, determines the amount of grain shown in the images, and adjusts an operational characteristic of the agricultural machine based on the amount of grain determined to be shown in the images.
