摘要： In one aspect, the present subject matter is directed to a method for maintaining a desired amount of residue coverage in a field during a tillage operation. The method includes generating, with a computing device, an available residue map that includes an amount of available residue at each location of the field using a yield map and/or crop biomass. The method also includes generating, with the computing device, a desired residue coverage map that includes a desired amount of residue coverage for each location within the field. Further, the method includes determining, with the computing device, an amount of residue that needs to be incorporated into the surface of the field based on the available residue map and the desired residue coverage map. Moreover, the method includes generating, with the computing device, a prescription map for the field based on a correlation between a tillage parameter of one or more ground-engaging tools of the implement and the amount of residue that needs to be incorporated into the surface of the field. In addition, the method includes controlling the tillage parameter based on the prescription map during the tillage operation to maintain the desired amount of residue coverage at each of the locations in the field.

摘要： In a crop harvesting machine there is provided a pair of hydraulic float cylinders or springs for a header such as a rotary mower relative to a self-propelled vehicle, where a float spring force is controlled to provide a predetermined lifting force is provided to the header. The spring force is varied in response to detection of ground speed to decrease the lifting force at higher ground speeds. A position sensor is used to generate an indication of movement and/or acceleration. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. In order to reduce static friction so that the system can react quickly, an arrangement is provided for causing relative reciprocating movement in an alternating wave pattern between the piston and cylinder.

摘要： An agricultural working machine, in particular a tractor, has at least one agricultural working unit for working a crop field including a multitude of useful plants, and a camera system which includes a 3D camera. The camera system is configured for generating with the 3D camera 3D information regarding the crop field by recording stereoscopic image pairs along two different viewing axes. The viewing axes proceed from optical centers of the 3D camera, which are connected to each other by a baseline that is inclined relative to the horizontal.

摘要： In one aspect, a method for automatically controlling a height of an implement of an agricultural work vehicle relative to a ground surface may include monitoring, with one or more computing devices, the height of the implement relative to the ground surface. The method may also include determining, with the one or more computing devices, an implement height error by comparing the height of the implement with a predetermined target height. The method may also include calculating, with the one or more computing devices, a proportional signal based on the implement height error raised to a power greater than one. The method may also include adjusting, with the one or more computing devices, the height of the implement relative to the ground surface based on the proportional signal.

摘要： An agricultural vehicle includes a frame and a plurality of suspension assemblies coupled to the frame. The plurality of suspension assemblies configured to together increase or decrease a vertical distance between the frame and a surface supporting the agricultural vehicle. The agricultural vehicle also includes a plurality of wheels. One wheel of the plurality of wheels is coupled to each suspension assembly, and at least two wheels of the plurality of wheels are movable about a steering axis. The agricultural vehicle further includes at least two actuators. Each of the at least two actuators is coupled to a respective suspension assembly of the plurality of suspension assemblies and is configured to move one of the at least two wheels.

摘要： A system is suitable for connecting multiple implements to a three-point hitch of mobile machinery for controllable side-shifting movement of the connected implements. The system comprises first, second and third apparatuses, each apparatus comprising a first framework, a slidable second framework laterally slideable relative to the first framework, at least one connector supported by the slidable second framework for connecting the slidable second framework to one of the implements, and at least one driver connected to the first framework and the slidable second framework for driving the slidable second framework laterally back and forth relative to the first framework. The second apparatus is attached to one side of the first apparatus and the third apparatus is attached to the other side of the first apparatus.

摘要： An implement control system includes an automatic control valve assembly configured to utilize fluid from a supply conduit to cause a cylinder to raise a ground engaging tool relative to a soil surface and to utilize the fluid flow from the supply conduit to cause the cylinder to lower the ground engaging tool relative to the soil surface while an automatic control mode is active. The implement control system also includes a controller configured to control the automatic control valve assembly based on a position of the ground engaging tool relative to the soil surface to control the position of the ground engaging tool relative to the soil surface while the automatic control mode is active. The controller is also configured to deactivate the automatic control mode in response to fluid pressure within a first manual control conduit exceeding a threshold pressure.

摘要： A remotely positionable stabilizer wheel arrangement for a towable agricultural implement utilizes an electronic control unit that receives an input signal indicative of a desired position of the stabilizer wheel, and/or a desired depth of penetration of tillage tools operatively attached to the front and rear of the implement frame, to automatically control an electrically powered linear actuator of the remotely positionable stabilizer wheel arrangement to position and hold the stabilizer wheel at the desired position of the stabilizer wheel.

摘要： A seed planting unit of an agricultural implement may include a wheel support arm having an upper portion and a lower portion. A wheel may be rotatably supported by the lower portion of the wheel support arm, the wheel configured to contact the soil surface to define a penetration depth setting for the ground engaging tool relative to the soil surface. A depth stop member may be provided in operative association with one of the support structure or the wheel support arm. A depth adjustment member may be selectively axially movable relative to the other of the support structure or the wheel support arm to vary a relative distance between an abutment portion of the depth adjustment member configured to abut against the depth stop member and the other of the support structure or the wheel support arm to set the penetration depth setting for the ground engaging tool.

摘要： A harvesting system includes a header pivotably attached to a combine. The header includes a center section to which a left wing and right wing are pivotably attached. A wing locking system of the harvesting system includes first and second engageable states that enable dynamic wing behavior and reduce structural load. The first state corresponds to a harvesting configuration of the header in which the wings are allowed to pivot to allow the header to follow changes in terrain. The second state corresponds to a configuration in which the header is elevated relative to the ground. In the second state, the ability of the wings to pivot is minimized as compared to the first state, which allows the header to be maintained in a substantially fiat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.
