  • Patent number: 6644003
    Abstract: A leaf vacuum and mulching implement for attachment by three-point-hitch to a farm tractor and driven by mechanical connection to the tractor's power tack-off unit (PTO). The implement utilizes a broad vacuum deck having polymeric skirts in near proximity with the ground and a floating three-point-hitch system for lifting the vacuum deck and allowing it to follow the ground contour. High velocity fans blow debris collected by the vacuum deck to a unique, rotating, multifaceted, conical shredding rotor prior to directional dispersion.

  • Patent number: 6616527
    Abstract: Yield monitor apparatus and methods for a forage processing machinery are provided. The yield monitor measures a forage yield by variously measuring a forage impingement force, a forage volume flow, a forage volume increment accumulation, or a forage processing machinery drive load. The yield measures an impeller speed. The yield monitor may generate a yield amount, with the yield amount capable of being stored and displayed to a forage processing machinery operator. Alternatively, the yield monitor may generate a groundspeed control signal that is used by the forage processing machinery to control a forage processing machinery groundspeed or other forage processing machinery parameters.

  • Patent number: 6615569
    Abstract: A control system for an agricultural harvester having a frame and a header. The header attaches to a feeder which connects the header to the harvester, and header to feeder attaching point has a position which is adjustable relative to the frame. In at least one mode, when an operator raises the feeder above a predetermined height, the control system automatically levels the header to the frame of the harvester, even though the header was being operated manually in a lowered position. The control system includes a feeder housing limit switch that indicates when the operator raises the feeder above a predetermined height. When operating in the automatic centering mode, the header tilt control module compares the centering signal and the balance signal to automatically level the header relative to the frame of the harvester.

  • Patent number: 6615570
    Abstract: A system for harvester header height and tilt control includes a sensor, such as a crop edge detector, mounted on the harvester for predicting ground contour of an area a substantial distance in front of the header for generally the entire width of the header. An on-board processor calculates the desired header height and tilt for that area in advance of the harvester reaching the area. The early ground contour measurements enable faster and smoother header height adjustments requiring reduced hydraulic power. The predicted contour also facilitates early compensation for the effects of abrupt header attitude changes resulting from harvester ground wheels or tracks riding on that contour. The system can be used to maintain header height a preselected distance below the crop heads to reduce harvester throughput.
