ABSTRACT:
An improved picker bar assembly for a cotton harvester. The assembly includes a cast arm with an extension which is press fitted over a hollow aluminum picker bar. The extension projects downwardly into the picker bar drum head to provide the wear surface for the picker bar journal and to distribute a greater proportion of picker bar loading to the arm. The spindle drive shaft bearing is located in the cam arm rather than within the picker bar to thereby permit utilization of a larger and higher capacity bearing.
