A method, using an autonomous, unmanned device and a control device, includes the steps of automatically harvesting feed crop in a part of a crop field by means of the autonomous, unmanned device; automatically loading the harvested feed crop directly into a storage space provided on the autonomous, unmanned device without said harvested feed crop contacting the soil; choosing a destination location from a feeding location and a stationary crop processing location; automatically transporting the harvested feed crop from the crop field to the chosen destination location by means of the autonomous, unmanned device; and automatically unloading harvested feed from the storage space of the autonomous, unmanned device at the chosen destination location.

A grain bin aeration system has inlet ducting in communication with the hollow interior of the storage bin adjacent a perimeter of the storage bin and exhaust ducting in communication with the hollow interior of the storage bin at a central location within the storage bin. A first portion of the inlet ducting is directed to the top end of the bin so that aeration flow therethrough is directed downwardly through the material in the storage bin to the exhaust ducting. A second portion of the inlet ducting is directed to the bottom end of the bin so that aeration flow therethrough is directed upwardly through the material in the storage bin to the exhaust ducting.

Aspects of the disclosure relate to temporary storage systems for the temporary storage of agricultural grain products. The temporary storage systems include an enclosing retaining wall comprised of a plurality of free-standing wall sections. The enclosing retaining wall can include multiple free-standing wall sections arranged in a circular, oval, or substantially rectangular shape. Each free-standing wall section includes one or more corrugated panels coupled with one or more support structures. The support structures can be constructed from a rigid material and include ground supports, which permit the free-standing wall sections to maintain a predetermined angle based on the angle of repose of the agricultural products stored. Each corrugated wall panel includes a plurality of perforations and a plurality of corrugations configured to provide ventilation to the grain product, while maintaining the necessary rigidity to retain the loads imposed by the granular material.

A grain aeration system facilitates thorough and efficient aeration of grain within a grain bin. The system includes a grain bin having a top vent and a bottom vent. A stand is positioned within the grain bin. A duct includes a loop section supported on the stand and an extension extending from the loop section out through the bottom vent in the grain bin. The duct has a duct wall and a plurality of perforations extending through the duct wall. A blower drives air flow out of the bottom vent creating air flow into the grain bin through the top vent and into the duct wherein the blower is configured to aerate grain positioned within the grain bin.
