Abstract

Plastic hoods and dividers are provided for use with row crop heads. The hoods and dividers are single walled and self-supporting. The single-walled hoods and dividers are preferably manufactured through a rotational molding process wherein a non-stick coating, such as polytetrafluoroethylene, is attached to portions of the mold.
