A combine and combine conversion for collecting agricultural plants in a manner that separates various parts of the plants for collection or disposal. A combine is provided with an improved system for collecting and cleaning seed of an agricultural material such as cannabis while collecting lightweight chaff, such as trichomes, and returning stalks back to the agricultural field. The system provides for rapid conversion of a combine to seed and chaff collection and back again.

A combine harvester includes a cleaning shoe, which has a chaffer, a sieve below the chaffer, a blower configured to direct air rearward and upward through the sieve and the chaffer, and an air channel assembly defining a plurality of longitudinal air channels positioned to receive air from the blower under a forward end of the sieve and deliver the air to a position rearward along a length of the sieve. The air channels are spaced such that the air channel assembly defines free paths between adjacent air channels such that grain falling downward through the sieve does not obstruct rearward air flow through the air channels.

A method and system of a pneumatic conveying system for moving separated grain and small plant material to an onboard storage tank or out of the combine harvester. The pneumatic conveying system having a gateway for introducing the material into an air flow channel, and with a diverter valve or an airlock directing separated grain and small plant material to the tank or outside of the harvester.

A combine crop trash removal system for mounting to a combine corn harvester using hydraulically driven air blowers coupled to the combine header control system for reduction and/or removal of stalks, leaves, dirt and dust type material from accumulating on the combine feeder house and obscuring the operators view of the operating combine header during operation of the combine harvester for corn picking. The air blower may also be driven electrically or pneumatically. The operator of the combine harvester controls the crop trash removal system from the operator cab of the combine harvester.
