Abstract
A cotton cleaner for cleaning cotton harvested by a cotton stripper comprises grid bars, a saw drum, and a buffer ring. The saw drum is positioned in proximity to the grid bars and rotatable about an axis of rotation of the saw drum for saw teeth of the saw drum to remove cotton from harvested cotton plant material that passes between the saw drum and the grid bars. The buffer ring is supported by and disposed around the saw drum such that an outer diameter of the buffer ring is greater than an outer diameter of the saw teeth for contact of a grid bar of the grid bars with the buffer ring upon deflection of that grid bar toward the saw drum.
