Abstract: A vertically adjustable and rotatable moistener column for a cotton picker row unit. The moistener column includes rotating base structure permitting the column to be rotated between a normal operating position and a service position wherein access to the pad supports and moistener pads is facilitated. The rotating base includes indexing structure for firmly securing the moistener column in either the operating or the service position and for facilitating rotation of the column between positions after moving the column vertically.

Abstract: An automatic lubrication distribution system includes a conduit system for supplying equal volumes of grease to each of a plurality of row units, the row units each supporting a manifold which is connected to the conduit system and proportions the grease received therefrom to simultaneously supply first and second grease receiving areas having substantially different grease volume requirements. The distribution system, from the supply pump to the grease receiving areas, is completely passive and reqiures no control valves, flow dividers or metering pumps.

Abstract: A cotton picker row unit includes tandem drum structure for harvesting cotton from one side of a row of cotton. A front drum trash slot directs trash and cotton discharged from the front drum into the row and permits the rear drum to pick the discharged cotton. Fore-and-aft spaced discharge doors are located on the side of the unit and are connected so that cotton from the rear door is combined with that from the front door. The combined cotton is conveyed through a single duct to the basket. The tandem drum and side door structure provide a narrow row unit configuration, and a plurality of identical units are spaced on a harvesting frame forwardly of the drive wheels for picking narrow row cotton.

Abstract: A moistener pad including two sets of apertures extending diagonally from corner to corner of the pad to define X-shaped pattern which provides a uniform distribution of moistening fluid to the fins. One set of apertures is located between a first set of adjacent pairs of fins, and the other set of apertures is located between a second set of adjacent pairs of fins.

Abstract: Cotton suction doors for a cotton picker are rotationally molded from cross-linked polyethylene. Support and guide structure automatically direct the door structure to the operating position alongside the discharge openings in the row unit. The door structure includes two individual compartment structures which are movable in sequence and interlock with each other and with nozzle structure and duct structure to provide a compact and lightweight arrangement which is easy to attach to and remove from the row unit.

Abstract: Row unit support structure for a cotton harvester facilitating easy transverse adjustment of the row units on a support frame for servicing the units and/or changing the location of the units for differing row widths. The support frame includes a horizontal rail supported in generally cantilever fashion from the lift structure on the harvester, and individual row units are suspended for independent transverse adjustment on the rail by a roller assembly connected generally over the center of gravity of each unit. An additional roller attached at the upper rear of the unit runs on a second rail rearwardly and below the first rail to stabilize the unit. Removable pins lock each unit in position along the support frame. To adjust for different row widths or to move the units laterally for inspection or maintenance, the pins are removed and the units are rolled along the frame.

Abstract: Jet post assemblies providing both structural support and an air curtain over the floor panel structure of the cotton discharge compartment to increase the cotton-handling capacity of the compartment and prevent clogging in damp, high yield cotton. Air is bled from a nozzle located on the cotton-conveying duct and channelled through upright structural posts connected to the floor panel structure. Lower outlets in the posts direct air over the floor panel structure. The air preserves the kinetic energy of the doffed cotton and positively directs cotton to the discharge opening.

Abstract: A meter assembly for a grain drill or seeder or similar implement. The meter assembly is hinged at one end to the implement and held in place by over center latches. To inspect and service the meter assembly and to empty the material containers, the latches are released allowing the meter assembly to swing down. The meter is driven by a pair of gears which automatically disengage when the meter assembly swings away from the latched working position and engage when the assembly is swung back to the working position. Removal and replacement of chains and bolts are eliminated to increase serviceability of the meter assembly.
