Abstract: A folding door or gate arrangement and method of operation thereof for a mobile cotton harvesting machine including a tiltable cotton module builder. In one embodiment, folding door or gate arrangement includes primary and secondary folding door segment pivotal between a folded or closed position in at least partially closing relation to an open end of the module builder and an unfolded or open position at least substantially parallel to a floor thereof, and a door driver arrangement connected between the primary door segment and the secondary door segment including a pivoting link element that facilitates pivotally moving the secondary door segment while the module builder is pivoted to an unloading position without exerting binding or potentially damaging loads against the door segments or the drivers to provide a straight inclined path for unloading or loading cotton onto of from a surface lower than the module builder.

Abstract: A method for forming a cotton module on a mobile cotton harvester, including the steps of: (a) removing cotton from cotton plants as the harvester is moved across a cotton field; (b) conveying the removed cotton into a cotton receiver structure including a plurality of surfaces of known extent defining and substantially enclosing an interior space; (c) distributing the cotton in the cotton receiver structure substantially evenly with respect to a selected one of the surfaces of the receiver structure; and (d) periodically compacting the cotton in the cotton receiver structure substantially evenly against the selected one of the surfaces by forceably moving a compacting element having an extent only marginally smaller than the extent of the selected one of the surfaces against the distributed cotton and toward the selected one of the surfaces.
