Cotton picker bar lubricant seal

摘要

A grease reservoir is provided for the wear surfaces between a cotton harvester picker bar and its journal support in the picker drum. The reservoir is formed by upper and lower resilient seals acting to retain grease within the wear area and prevent entry of contamination into the reservoir area. A grease repository is further provided at the upper portion of the reservoir to assure lubrication of the vertical wear surfaces during harvesting operations and to extend periods between required maintenance.
