Abstract: A self-propelled harvesting machine includes an internal combustion engine and an electronic control arrangement that is coupled to the internal combustion engine and that is provided as input the rotational speed of the internal combustion engine and that can be provided with information as to whether the harvesting machine is in operation on public roads or in a harvesting operation. The control arrangement provides as input during the harvesting operation in an automatic operating mode the rotational speed of the internal combustion engine as a function of the situation in a harvesting operation of the harvesting machine as controlled by the control arrangement. In addition, the internal combustion engine can be operated in an efficient operating mode at a local minimum of the specific fuel consumption.

Abstract: A harvesting machine combination for the utilization of harvested plant remains is provided and includes a combine with an outlet for harvested crop remains, a self propelled forage harvester that includes a conveyor to take over the harvested crop remains from the outlet of the combine, a discharge arrangement for the harvested crop remains, an engine for the drive of the conveyor and a container to take up the harvested crop remains delivered by the discharge arrangement. The combine is equipped with a transmitting arrangement for the transmission of position data and/or operation direction and speed data of the combine. The forage harvester is equipped with a receiving arrangement that interacts with an automatic steering and speed input arrangement of the forage harvester that can be operated on the basis of the data received by the receiving arrangement in order to permit the forage harvester to follow the combine automatically.

Abstract: An opener assembly includes a single opener disk rotatably supported from a drawbar and angled approximately five degrees from the forward direction to define a shadow area behind the trailing surface of the disk. A material placement boot and delivery tube are supported adjacent the trailing surface substantially entirely within the shadow of the disk and have profiles conforming to the furrow profile. The boot and the outlet portion of the tube also lie within the periphery of the disk for protection. The tube has an upper portion with a round cross section which changes to an elliptical cross section towards the outlet to remain within the shadow while retaining high throughput capabilities. First and second wheels are supported on opposite sides of the disk to urge soil downwardly behind the outlet of the delivery tube immediately after the material is deposited.

Abstract: A row cleaner device for a furrow forming row unit includes a support arrangement with a parallel linkage having a single acting hydraulic cylinder connected between upper and lower links. The cylinder extension is controlled by a hydraulic circuit to provide adjustable down pressure to maintain consistent operation of the cleaner devices in varying ground conditions. A tensioning device such as a spring extending generally parallel to the cylinder acts to retract the cylinder. A blocking valve can be closed to maintain the cleaner device in the raised position and can lock the cylinder in any desired extended position. An energy storage device such as a spring compressed between the cylinder and one of the links permits limited vertical movement of the linkage without change of cylinder extension to protect the device and accommodate obstacles and ground surface irregularities in the path when the cylinder is locked in position.

Abstract: A shallow-toothed clearing disk pivotally supported from the upper end of the opener drawbar assembly. A four bar linkage is connected to the forward end of the drawbar by a bracket which includes at least one link and corresponding pivot structure located above the drawbar to increase trash clearance and reduce trash build-up. The shallow rounded gullets between pointed teeth provide good disk depth control and trash penetration while reducing soil penetration and soil disturbance. The gullets also hold and prevent sliding of trash away from the clearing influence of the angled disk. The disk effectively clears trash to the side of the opener opposite the gauge wheel to assure optimum depth gauging for the opener. The gear-type structure is capable of operating over a wide range of down pressures and loads while breaking any existing crust in the cleared path with little soil disturbance.

Abstract: A combination seed and fertilizer opener having separate placement includes a first angled flat disk with a gauge wheel arrangement providing an initial furrow for a first material such as fertilizer. A second opener disk, smaller than the first and concave rather than flat, includes an edge that projects forwardly along the trailing side of the first disk to a forwardmost edge location adjacent the hub of the first disk. The hub of the concave disk is very closely adjacent the trailing edge of the large disk. A tube and boot assembly terminates within the concavity of the second disk near the rear periphery of the first disk. The concave disk forms a seed furrow to receive seed or second material from the tube and boot assembly. The front of the concave disk runs in undisturbed soil but is sufficiently close to the fertilizer furrow to press and cover the fertilizer. The second disk concavity also prevents excessive soil throw.

Abstract: A pair of angled disks supported by a four bar linkage from the upper end of the opener drawbar assembly clears trash from a narrow area in front of the opener. The four bar linkage has a virtual center located on or close to the center of the opener disk for good cleaning wheel tracking and for permitting the clearing disks to be spaced closely to the opener disk without interference between the disks. The clearing disks can rock vertically to follow ground contour and prevent excessive digging and soil movement. Shallow teeth on the disks also reduce soil penetration and soil disturbance.
