• and
• including an attaching bracket located at the forward end of the cover structure, and wherein the housing includes a mating forward bracket receiving member, and means for maintaining the bracket in the bracket receiving member when the cover structure is attached.

• wherein the plastic cover includes a hollow portion separating the inner wall from the outer wall;
• and
• wherein the outer wall includes a top portion which slopes downwardly to funnel loose cotton outside the housing into the housing and the inner wall includes a surface directing the cotton along the length of the stripper rolls downwardly towards the respective augers for reduced cotton loss.

In a cotton harvester having a main frame supported for forward movement through a field of cotton planted in parallel rows, a row unit for stripping cotton from a row of plants, comprising:

• and
• wherein the row unit housing includes at least one auger trough extending below the augers and having at least one boundary which is planar and extends generally the length of the augers for facilitating cotton stalk breakage, the auger trough including forwardly located upright slots and fore-and-aft extending slots located rearwardly of the upright slots.

In a cotton harvester having a main frame supported for forward movement through a field of cotton planted in parallel rows, a row unit for removing cotton from a row of plants and delivering removed cotton and plant debris rearwardly,

• a row unit frame assembly supported from the harvester main frame and defining a row-receiving area;
• fore-and-aft extending harvesting and conveying structure supported by the frame assembly;
• a fore-and-aft extending housing cover removably supported by the frame assembly for generally containing removed cotton in the housing, the housing cover comprising a nonmetallic outer surface sloping inwardly and downwardly toward the row-receiving area and an inner surface located between the outer surface and the harvesting and conveying structure and being generally concave in the downward direction for directing removed cotton towards the conveying structure;
• wherein the housing cover comprises a plastic structure having a double wall construction with first and second walls defining the outer and inner surfaces, respectively;
• and
• wherein the first end portion includes a first bracket member located therein, and a mating bracket member supported by the frame assembly for receiving the first bracket member, and wherein frame assembly includes means for supporting the second end portion.

Row unit housing structure for a cotton harvester row unit having a fore-and-aft extending frame assembly with a drive support panel and defining a row-receiving area and cotton removing and conveying structure adjacent the row-receiving area, the housing structure comprising:

• a unitary plastic member removably connected to the frame assembly above the cotton removing and conveying structure and having an inner wall and an outer wall and first and second fore-and-aft spaced end portions;
• the outer wall having a first shape with an upper fore-and-aft extending portion sloping toward the row-receiving area, and a forward upright portion opening towards the row-receiving area;
• the inner wall having a second shape differing substantially from the first shape and located generally below but offset from the upper fore-and-aft extending portion, the inner wall being concave in the downward direction;
• and
• end portion support structure comprising ledge structure connected to the drive support panel, and further including a movable upper panel located above the ledge structure and having a confining position for retaining the second end portion on the ledge structure with the inner wall above the cotton removing and conveying structure, and a release position for permitting the second end portion to be lifted from the ledge structure to facilitate removal of the plastic member from the frame assembly and thereby provide generally unimpeded access to the cotton removing and conveying structure.
