ABSTRACT:
An improved picker bar assembly for a cotton harvester includes a thin cylindrical sleeve which is pressed onto the upper end of the picker bar. The sleeve has an inner diameter which is smaller than the outer diameter of the upper end, a lower portion defining the journal area between the picker bar and the picker drum head, and an upper area which mounts the cam arm. The sleeve increases the shear and bending strength and fatigue life of the upper portion of the picker bar, particularly adjacent the grease hole which communicates lubricant between the hollow interior of the picker bar and the journal area.
