One or more techniques and/or systems are disclosed for harvesting cotton that includes an air duct for a cotton stripper having a first portion having a rear separation duct panel configured to separate non-cotton material from cotton material, wherein the rear separation duct has a planar lower wall. The air duct further includes a second portion movably coupled to the first portion, wherein the second portion has an opening configured as an inlet that receives the cotton material and the non-cotton material, and the second portion has an open floor portion. The planar lower wall of the rear separation duct panel extends to overlap with at least part of the open floor portion.

One or more techniques and/or systems are disclosed for harvesting cotton that includes an air supply system with a cotton flow accelerator having an air source and a nozzle having an inlet configured to receive air from the air source and an outlet configured to direct airflow pushing cotton away from a cross auger. The cotton flow accelerator further includes one or more ducts coupling the nozzle to the air source to form an air path therethrough, wherein the nozzle is coupled adjacent to the cross auger and directs the airflow to define a positive airflow at the cross auger.

A feeding system for an agricultural implement includes a hopper configured to receive agricultural crop material. An auger extending across the hopper is configured to meter the agricultural crop material from the hopper into a tapered passageway. A movable belt is disposed along one side of the tapered passageway and is configured to urge the agricultural crop material through the tapered passageway toward an outlet of the tapered passageway to form the agricultural crop material into a mat having a thickness substantially equal to a width of the outlet.

A method of harvesting an agricultural product includes guiding the agricultural product through a plurality of inlets in a first direction with a plurality of airflows, separating the agricultural product from the first plurality of airflows, directing the agricultural product to a cross-conveyor, conveying the agricultural product through the cross-conveyor from the plurality of inlets to an outlet in a second direction, and guiding the agricultural product through the outlet in a third direction with a second airflow. The first direction is substantially parallel to a travel direction, the second direction is crosswise to the first direction, and the third direction is substantially parallel to the travel direction. The agricultural product is conveyed through the cross-conveyor substantially without the first plurality of airflows, and the second airflow includes the first plurality of airflows.

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.

An air system (50) for an agricultural harvester (10) includes an air flow splitter component (52) configured to be coupled to the agricultural harvester (10). The air flow splitter component (52) has an inlet (56) configured to receive air and a plurality of air outlets (58) configured to distribute the air. The air system also includes a plurality of air flow paths (60). Each air flow path of the plurality of air flow paths extends from a respective one of the plurality of air outlets and is configured to extend to a corresponding drum (12) of the agricultural harvester. Additionally, each air flow path includes a discharge outlet (80) that is configured to be disposed between a bottom surface (81) of the corresponding drum (12) and a bottom disc (85) of a doffer (42) of the corresponding drum (12) while the air system (50) is coupled to the agricultural harvester.
