A folding rear cross system for a harvesting device having a harvesting direction and a discharge includes first and second substantially linearly aligned reversible endless belt sections, positioned near the discharge and oriented transverse to the harvesting direction. Each belt section has an inboard end disposed in overlapping relationship with the inboard end of the other. A lifting device is attached to selectively lift and lower the first and second reversible endless belt sections to reverse the overlapping relationship.

A system for monitoring an extractor fan of an agricultural harvester includes an extractor fan having a shaft configured to be coupled to a rotational drive source for rotationally driving the shaft, a fan hub coupled to a lower shaft end of the shaft such that rotation of the shaft rotationally drives the fan hub about a fan hub axis, with the fan hub extending between an upstream side and a downstream side along the fan hub axis, and fan blades coupled to and extending radially outwardly from the fan hub. The system further includes a sensor that generates data indicative of acceleration of the extractor fan. Additionally, the system includes a computing system that determines an acceleration of the extractor fan based at least in part on the data, and determines whether the extractor is imbalanced based at least in part on the acceleration of the extractor fan.
