  • Patent number: 6640529
    Abstract: 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.

  • Patent number: 6612381
    Abstract: A disc gang is provided that is suitable for use as part of a multifunctional seedbed preparation implement or in a standalone disc harrow. The disc gang is configured to permit a gang angle of the disc gang to be adjusted to accommodate differing soil conditions and/or to obtain different tillage characteristics. The disc gang may include a frame mounted on a mainframe of a primary tillage implement such as a cultivator. The frame includes a main beam mounted on the implement's mainframe and a disc support beam connected to the main beam and supporting a plurality of rotating discs. The gang angle can be infinitely adjusted through a designated range by pivoting one end of the disc gang about a vertical pivot axis while permitting another end portion of the disc gang to slide along a support surface for that end.

  • Patent number: 6606956
    Abstract: A mechanical overload member apparatus for use with a planter apparatus including a coulter bar and coulter/fertilizer units mounted thereto, the coulter bar pivotally mounted to the underside of a wheel supported carrier frame designed for transport in a transport direction where a hydraulic cylinder is linked between the frame and the bar for moving the bar between a ground clearing transport position and a ground engaging position where the frame, cylinder and frame form a linkage path, the overload member linked within the linkage path such that a draft force applied to the bar in a direction opposite the transport direction causes a secondary force on the member and, when the secondary force exceeds a threshold force, the overload member failing and thereby rendering the linkage path non-rigid.

  • Patent number: 6604353
    Abstract: An elevated drawbar for a grain cart that can be attached to the rear end of an agricultural combine above the crop residue discharge opening. The elevated position of the grain cart drawbar allows the crop residue to be discharged under the drawbar. The crop residue can therefore travel unobstructed from the combine's discharge opening to the ground.

  • Patent number: 6581534
    Abstract: A pneumatic agricultural particulate material delivery system for delivering agricultural particulate material to a growing medium is disclosed. The delivery system includes a particulate material supply chamber, a furrow opening device configured to create a furrow in the growing medium, a plurality of tubes providing an interior passage extending from the particulate material supply chamber to an outlet proximate the furrow opening device and a pneumatic pressure source pneumatically coupled to the interior passage to supply pressurized air to the interior passage to move material within the interior passage. The plurality of tubes includes an end-most material delivery tube providing the outlet. The end-most material delivery tube includes a plurality of openings extending therethrough in communication with the interior passage. In one exemplary embodiment, the plurality of openings are louvered so as to extend at a downward angle towards the outlet.

  • Patent number: 6561535
    Abstract: An apparatus for linking first and second power ports on a variable length tongue assembly where the distance between the ports varies as a function of the degree to which the tongue assembly is extended, the apparatus including a receiver member that defines a receiver space for receiving the cable when the tongue assembly is in a retracted position, a flexible power cable that links the first and second ports together and that forms at least one curve proximate the first cable end and that is convex toward the receiving space, and a guide member that restricts bending of the cable between the curve and the second end such that, upon retracting the tongue assembly, the cable is forced into the receiving space and into a stowed position, at least one embodiment includes a sheath member that further restricts cable bending.

  • Patent number: 6557646
    Abstract: An agricultural tillage implement employing a series of apparatus to perform one-pass primary tillage is disclosed. A cutting disk is the first apparatus that works the field. These disks cut the residue laterally (across the machine) and mix the majority of the residue throughout the disk tillage profile. Additional conditioning occurs by knocking residue/stalks over into a prone position with large cast spools between each disk for quicker decay. Next, chisel plow units work the soil to fracture and loosen the soil, providing proper soil aggregate size and air pore space relationship throughout the shank tillage profile. The last apparatus to work the field is a set of leveling disks, or a combination of leveling disks and a rotary reel/drag harrow. The function of these will provide is to reduce clod size and leave the soil level and smooth enough to allow one-pass secondary tillage in the spring.

  • Patent number: 6527205
    Abstract: An agricultural particulate material delivery system for delivering metered agricultural particulate material to a growing medium includes first and second compartments adapted to contain different agricultural particulate materials, a material meter having an interior and a flow switching mechanism between the first and second compartments and the meter. The flow switching mechanism is actuatable between a first position in which the flow switching mechanism supplies material from the first compartment to the interior of the meter, a second position in which the flow switching mechanism supplies material from the second compartment to the interior of the meter and a third position in which the flow switching mechanism stops the supply of material from both the first and second compartments to the interior of the meter.

  • Patent number: 6517465
    Abstract: A method for controlling the drive mechanism of a utility vehicle having a power take-off shaft, where the drive mechanism including an engine, a transmission, a power take-off shaft clutch and a controller, operates the drive mechanism in a careful and economical manner. The method of controlling the engine includes the step of issuing an instruction for engaging the power take-off shaft clutch at a low rotational speed of the engine so that the power take-off shaft clutch is engaged in a controlled manner. If the rotational speed of the engine is above a threshold, the rotational speed is automatically reduced before the engaging the power take-off shaft clutch. After fully engaging the power take-off shaft clutch, the rotational speed of the engine is automatically increased until reaching of the rotational speed of the engine required for the nominal rotational speed of the power take-off shaft.

  • Patent number: 6513313
    Abstract: A support structure for a divider of an agricultural corn head that includes a first tension member that is pivotally attached to a second tension member. A stop is provided which prevents the lines of tension of the first and second tension members from aligning. The tension assembly can therefore buckle upwards when an object underneath the support structure is struck. A lateral support for the divider is also provided with a clearance opening for the tension assembly. The divider can be rotated rearward into a transport or a service position and securely locked in place. A shipping position is provided in which the support structure can be rotated rearward by disconnecting the tension assembly.
