  • Patent number: 6584919
    Abstract: An all wheel steer variable load carrying tractor vehicle which is particularly suited for towing crop input implements, the front section of which comprises a cab and engine the back section of which comprises several storage containers for carrying bulk crop inputs. The storage containers are releasably attached to the vehicle and can be changed based on the type of crop inputs applied and any implements towed by the vehicle. The vehicle is equipped with low impact tracks to increase maneuverability. The vehicle may also be equipped with a combination of high flotation tires or tracks to minimize soil compaction. A delivery system in combination with a control system coordinates the movement of the crop inputs from the vehicle to places located off the vehicle.

  • Patent number: 6230091
    Abstract: A variable flow spray nozzle system for delivering a plurality of crop inputs over an agricultural field using a spray boom having a plurality of release zones. Each release zone on the boom is has multiple nozzle modules, and each nozzle module is individually controlled and capable of variable flow. A control system in communication with each nozzle module and a positioning system, such as a GPS system, controls the application of multiple crop inputs so that the crop inputs are applied at a variable prescriptive rate. Thus, it is possible to vary the flow of crop inputs along the length of the boom as well as in a direction substantially transverse to the direction of the boom.

  • Patent number: 6198986
    Abstract: A pre-charged multi-variable rate crop input applicator implement comprising a plurality of crop input storage reservoirs located on the implement. The reservoirs on the implement are charged with crop inputs from a remote source. The crop inputs are released from the reservoirs on the implement to the field. Since the reservoirs are pre-charged with crop inputs, the time it takes for a crop input to reach the ground is negligible, making the implement particularly suited to precision farming applications. An accompanying control system controls the rate of discharge of crop inputs at each dispensing point on the implement allowing multiple crop inputs to be applied at a variable rate and at the desired prescriptive mix.

  • Patent number: 6122581
    Abstract: An improved mobile agricultural products application system including a multi-variable rate dispensing system particularly adaptable for use in site-specific farming, wherein selected discrete crop input delivery information unique to selected on-board crop input storage devices, and/or crop input transport systems, and/or crop input dispensing points is combined with anticipated field reference point data obtained with a machine positioning system, e.g. "Dead Reckoning", GPS, and/or radar, and a computer, to direct independent functioning of selected on-board storage devices, material transport systems, crop input release mechanisms and/or dispensing point mechanisms to ensure stored crop inputs are released and combined to vary a prescription of delivered crop inputs in a direction substantially transverse to the direction of machine travel as the crop input applicator machine(s) travels over a predetermined geographic land area.
