Abstract: A narrow row harvesting unit for harvesting a crop planted in closely spaced rows. In a cotton picker, the crop removing portion of the unit includes a tandem drum arrangement. The unit includes first and second row receiving areas spaced on the order of twelve inches (30 cm) apart and separated by a narrow stalk lifter. The crop removing portion of the row unit provides transverse movement of a first row of the crop towards a second row of the crop behind the stalk lifter. In the cotton picker unit, a forward upright drum includes spindles projecting through a grid bar arrangement intercepting the first row of crop to move the plants laterally along grid bars into the main crop removing zone which is aligned with the second row. A cutter offset just ahead of the forward drum severs the plants in the first row, and a rotating column with plant engaging projections cooperates with the drum to direct the severed plants into the standing second row.

Abstract: A wheel motor disconnect includes a rotatable plate with sized apertures including locking detents. A depressor pin extends perpendicularly from the plate. The apertures are received over shouldered spacers or guides which are connected to the wheel hub. In the drive position, the plate is located at the outermost ends of the spacers, and the pin is offset from the spring-loaded drive shaft to allow the shaft to drivingly engage a reduction gear arrangement. To disconnect the drive, the operator urges the plate axially inwardly against the bias of the drive shaft so that the apertures slide inwardly along the spacers to move the shaft out of driving relationship with the reduction gear arrangement. The operator then rotates the plate in a first direction so smaller apertures move into the shouldered area and prevent the plate from moving axially outwardly.

Abstract: An improved down pressure arrangement for an implement such as a multi-section grain drill having fixed-height section frames with corresponding gangs of opener assemblies. The opener assemblies of each gang are yieldingly biased downwardly by a spring and bracket structure operably connected to a rockshaft. One rockshaft per gang is provided, and each rockshaft is controlled by a single down pressure adjusting cylinder. The cylinders are connected in parallel and to a pressure regulator to provide adjustable and uniform average opener down pressure across the width of the drill for more contant opener depth in irregular ground conditions. Tension links connected to the bracket structure permit the opener assemblies to be raised from a ground-working position to a transport position.

Abstract: Hitch structure for towing first and second implements forwardly one behind the other in a transport position and in a side-by-side relationship in a field-working position. The hitch structure includes an elongated rear hitch pivotally connected to a rear corner of the first implement by a 180 degree horizontally folding hinge and rockable by a rear hydraulic cylinder between a transport position wherein the rear hitch connector for the second implement is centered behind the first implement, and a field-working position wherein the connector is offset to one side of the first implement. A fore-and-aft extending forward hitch includes an aft end pivotally connected to the first implement at a location offset to the side of the implement and a forward connecting end attached to a towing vehicle.

Abstract: A seeding implement such as a minimum tillage drill including a pair of trailing transport wheels located inwardly of the outermost ends of the implement frame, one of the wheels being a combination transport-drive wheel mounted on a pivoting wheel frame with a portion of the implement frame extending rearwardly over the wheel frame to act as a stop member for maintaining the trailing wheels in a generally level condition during transport but permitting the combination transport-drive wheel to rock downwardly and stay in ground contact when the openers lift the machine on uneven terrain or in hard ground conditions.

Abstract: A fore-and-aft extending transport hitch frame carried on a pair of ground wheels supports the innermost ends of a pair of end wheel wing drills and tows a trailing end wheel drill between the wing drills. The wing drills are connected to rearwardly angled upright pivot structures on the hitch frame by hinged bracket structure which causes the innermost ends of the wing drills to lift as the drills are pivoted forwardly toward a transport position. The forward end of the hitch frame is lifted to raise the outboard ends of the wing drills for transport. During planting operations the ground wheels effectively act as the inboard end wheels for the wing drills. The wing drills can rock vertically about the bracket structure hinge for good flexibility in the field-working position.

Abstract: Agricultural hopper structure for containing two different granular materials such as seed and fertilizer. Two molded plastic containers are nested together and supported on a frame. The nested ends of the containers are concave and convex, respectively, to provide a symmetrical appearance while establishing unequal container capacity. The nested containers include a downwardly directed ledge structure freely resting on a corresponding upwardly facing load-bearing surface of the frame to reduce the number of fixed attaching points. The upper portions of the containers extend above the frame and have outwardly convex sidewalls. The hopper structure is fabricated by first nesting the containers and then lowering the nested containers onto the frame.

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.
