Cotton picker moistener supply system

1. Field of the Invention A moistener supply system for a cotton picking machine including a cleaner injection system that supplies cleaner to the system from a location remote from a water tank or other source of water. The outlet of the cleaner injection system preferably is positioned at a location that assures good mixing of the cleaner with the water before the resultant moistener is dispensed onto the moistening pads. Cleaner flow rate preferably is slaved to the water flow rate in order to maintain a generally constant cleaner concentration in the moistener in the absent external intervention. The cleaner flow rate can also be adjusted independently of the water flow rate to vary the cleaner concentration to meet the needs of the prevailing operating conditions. The cleaner concentration adjustment may be effected manually, automatically, or a combination of both.
