  • Patent number: 5137117
    Abstract: The present invention relates to a lubrication system for an agricultural implement such as a cotton harvester having a plurality of harvesting units mounted thereon. Each harvesting unit of the cotton harvester includes a harvesting mechanism whose operation is facilitated by supplying lubricant thereto. The lubrication system preferably includes an on-board grease reservoir with a constant displacement pump assembly having an input connected to the reservoir and an output for providing lubricant under pressure to the harvesting mechanisms of each harvesting unit. The pump assembly is operated under the influence of a controller which operates the pump for a preselected period of time thereby causing preselected amounts of pressurized lubricant to be provided to the harvesting mechanism of each harvesting unit.

  • Patent number: 5105609
    Abstract: A system for mounting and supporting harvesting units on a forward end of a cotton harvester frame to allow them to be slidably moved relative to each other and laterally along an elongated tool bar structure. The tool bar structure is pivotally connected to the cotton harvester frame by a lift assembly. The harvesting units hang in a cantilevered fashion from and are independently connected at their rearward edges to the tool bar structure by a slide support structure which facilitates visibility of the harvesting units from a cab region of the harvester. The slide support structure maintains a non-rotatable and non-point contact relationship with laterally elongated generally flat support surfaces defined between opposite ends of the tool bar structure whereby substantial surface area contact is provided between each side support structure and the support surfaces on the tool bar structure.

  • Patent number: 5090184
    Abstract: A system for controlling the elevation of a harvesting unit of a cotton harvester relative to a ground surface. The control system includes a valve assembly whose position controls operation of a lift mechanism connected to the harvesting unit and which is operated by a ground contour sensor assembly carried by the harvesting unit. Harvesting unit elevation is correlated with the extent that the ground contour sensor assembly moves relative to the harvesting unit. The ground contour sensor assembly includes a shoe with a ground engaging surface wherein such surface is movable vertically relative to the harvesting unit and also is pivotable sideways about a fore-and-aft extending axis thereby enhancing ground contact of the sensor assembly with the ground contour.

  • Patent number: 5077960
    Abstract: A latching mechanism for a laterally movable harvesting unit of a cotton harvester. The latching mechanism includes a latching pin which is associated with the harvesting unit for movement therewith and which is resiliently biased in two opposite directions. The latching pin is endwise movable along a generally straight line path between a locked position whereat the pin inhibits lateral movement of the harvesting unit and a released position whereat the pin allows lateral movement of the harvesting unit. A handle, which is selectively movable between locked and released positions, is connected to and moves the latching pin between corresponding positions. The resiliency of the latching pin allows movement of the handle between positions while facilitating consequent movement of the latching pin between corresponding positions.

  • Patent number: 5062316
    Abstract: An apparatus for controlling the position of an operating handle includes a plate which couples such operating handle to a device such as a hydraulic valve. The plate includes a detent notch, a shoulder and a control surface. An auxiliary lever is mounted for pivoting movement between a first, engaged position and a second, disengaged position and is maintained in either position by a compression spring. Such compression spring exhibits toggling movement as the lever is moved between positions. The lever includes a pin for engaging the detent notch when the lever is in the first position and the handle is thereby retained in a predetermined position. When the pin is in contact with the control surface and with the shoulder, the handle is retained in an operating position. Movement of a stop mechanism to a position which does not obstruct handle movement also permits the operating handle to move to a "float" position.

  • Patent number: 5058685
    Abstract: An apparatus for mounting a dozer blade for vertical and angular movement relative to a frame of a wheeled implement. The mounting apparatus a mounting mechanism which allows the dozer blade to be mounted close to the wheels to either end of the implement and which permits angular movement of the blade about a generally vertical axis and vertical movement of the dozer blade about a generally horizontal axis. The mounting apparatus further includes a linearly distendable driver which extends laterally across the frame of the implement and a linkage mechanism which improves angling moments and maximizes the driving force imparted to the blade upon extension of the driver. The linearly distendable driver and linkage mechanism operate in combination and in a closely confined area adjacent to the implement frame for effecting extended angular movement of the dozer blade.

  • Patent number: 5053960
    Abstract: A microprocessor-based electronic control system for a powershift transmission having at least one proportional actuator, such as a solenoid-operated proportional valve, is disclosed. The controller operates a plurality of on-off solenoid valves and the solenoid-operated proportional valve to provide operator-selected gear shifts in both forward and reverse directions having controlled clutch engagements achieved by modulations of clutch engagement pressure by the proportional valve. The key parameters associated with the gradual clutch engagement are all easily varied by the controller, most under program control during operation, to provide for optimized clutch engagements for smooth gearshifts. The key parameters include: fast-fill clutch delay, initial clutch engagement pressure, rate of increase of clutch engagement pressure, and the length of the reduced pressure clutch engagement interval.
