A harvester having a harvesting structure for harvesting crop and a crop receptacle for receiving harvested crop. The harvester comprises a crop conveying fan configured to operate at a fan speed to facilitate transfer of harvested crop from the harvesting structure to the crop receptacle. A control system for controlling the fan speed based on crop mass flow comprises a crop mass flow feedback device that provides a crop mass flow feedback signal indicative of crop mass flow. A controller is in communication with the crop mass flow feedback device and is configured to automatically lower the fan speed when the crop mass flow feedback signal indicates a lower crop mass flow and automatically raise the fan speed when the crop mass flow feedback signal indicates a higher crop mass flow.

A series-parallel hybrid power cotton picker includes a series-parallel hybrid power system; the series-parallel hybrid system includes an engine, a gearbox, a coupling device, a differential, a generator, battery, a main controller, a walking motor controller, a picking motor controller, a fan motor controller, a packing motor controller, a cotton collection motor controller, and a conveyor motor controller; the engine can transmit the power to the coupling device through the gearbox, and the coupling device couples the power of the engine and the walking motor, and then transmits the power to the wheels through the differential. The present disclosure achieves mechanical decoupling between the various working systems of the cotton picker through distributed electric drive, solving the problems of multiple components, long paths, and inability to adjust operating parameters in real time in traditional cotton picker transmission systems.

An outlet assembly for a row unit of an agricultural harvester includes an input portion configured to be coupled to a frame of the row unit. The input portion includes an inlet configured to receive agricultural product and an outlet configured to expel the agricultural product. The outlet assembly also includes an output portion having an inlet configured to receive the agricultural product from the outlet of the input portion and an outlet configured to direct the agricultural product into a duct of an air-assisted conveying system. The output portion and the input portion are at least selectively coupled to one another and configured to at least selectively rotate relative to one another.
