HARVESTER TRANSPORT PREPARATION

A harvesting platform is connected to a combine for movement with the combine over the ground surface. The harvesting platform includes a cutter bar that cuts a crop being harvested, and a reel that presses the crop against the cutter bar during harvesting. The cutter bar moves between a cutter bar harvesting position and a cutter bar transport position, and the reel moves between a reel harvesting position and a reel transport position. A controller receives a first signal from a user via a user interface, sends a second signal to the cutter bar to move the cutter bar between the cutter bar harvesting position and the cutter bar transport position in response to the first signal, and send a third signal to the reel to move the reel between the reel harvesting position and the reel transport position in response to the first signal.

FLEXIBLE HEADER WITH SECTIONAL HEIGHT ADJUSTMENT
20200375107 · 2020-12-03 ·

A flexible harvesting header (40) having multiple sections supported by support arms (74), with the height of each arm being adjustable in response to a changing load. Load sensors (504) at first ends of the arms sense loads and generate electronic load signals. Hydraulic cylinders (80) at second ends of the arms are actuatable to raise and lower the first ends. A controller receives the load signals, determines whether actuating one or more of the hydraulic cylinders (80) is warranted due to a changing load, and if so, changes a hydraulic pressure to raise or lower the first ends to offset the changing load. Actuation may be warranted if the changing load exceeds a predetermined value. Further, the entire flexible cutter bar (68) may be raiseable in response to an electronic raise signal, and the controller may actuate all of the hydraulic cylinders (80) to raise the front ends of all of the support arms (74).

METHOD FOR CONTROLLING THE HEIGHT OF A HARVESTING IMPLEMENT RELATIVE TO THE GROUND AND RELATED HEIGHT CONTROL SYSTEMS
20200375106 · 2020-12-03 ·

In one aspect, a method for automatically controlling a height of a harvesting implement of an agricultural vehicle relative to a ground surface includes receiving height data from a plurality of height sensors spaced apart relative to the harvesting implement with a known spatial relationship and analyzing the height data in combination with position data associated with the known spatial relationship of the plurality of height sensors to establish a correlation between the height data and the position data. In addition, the method includes determining at least one control output for controlling an operation of a height cylinder and a tilt cylinder provided in operative association with the harvesting attachment based on the established correlation, and controlling the operation of the height cylinder and/or the tilt cylinder based on the control output(s) to adjust the vertical positioning and/or the lateral tilt of the harvesting attachment relative to the ground surface.

GANG ARM GAUGE WHEEL HEIGHT CONTROL FOR CROP HARVESTING DEVICE

A harvesting head for an agricultural harvester including a center frame section that is pivotally coupled to each of a left frame section and a right frame section. The elevation or height of the center frame section is determined by setting a height of the inner gauge wheels of the left and right frame sections. A gauge assembly for each of the left and right frame sections includes a linking member that spans between and operatively connects to outer and inner gauge wheels. The gauge assemblies are operably connected to the left and right frame sections to adjust an elevation of the outer and inner gauge wheels relative to the linking member to thereby adjust the elevation or height of the frame section when actuated by an actuation mechanism.

Floatation Adjustment Device

An eccentric mount is used to adjust floatation force applied to a cutter bar of a pull type mower when the cut height of the cutter bar is changed. The eccentric mount is rotated to increase or decrease the tension on springs suspending the cutter bar. The eccentric mount is calibrated to adjust incrementally in relation to the position of the skid shoes to provide a floatation force to the cutter bar appropriate to the cutter height as determined by the spring shoe setting.

Floatation Adjustment Array for Harvester and Methods of Using the Same
20200352102 · 2020-11-12 · ·

A header floatation system that includes a floatation mechanism which includes a first end and a second end opposite the first end, a first floatation adjustment array which includes at least a first contact point, a floatation mechanism mount which includes at least a second contact point, and a floatation mechanism fastener. The first end of the floatation mechanism can be mechanically linked to the floatation mechanism mount. Either the first floatation adjustment array or the floatation mechanism mount can include a third contact point. The floatation mechanism fastener can be positioned adjacent to, on, or through at least the first or second contact points aligning contact between the floatation mechanism mount and the first floatation adjustment array.

Draper header for harvester providing floatation to gauge wheels

A draper header for a harvester useful for providing hydraulic lifting and lowering of ground wheels. Hydraulic cylinders are capable of being actuated to independently lower and raise the ground wheels of the header while using the floatation pressure from the lift cylinders of the harvester. First and second hydraulic cylinders are fluidically coupled to a charge pressure of the harvester, the charge pressure providing a floatation pressure to position first and second ground wheels at a lowered operation mode and a raised operation mode.

POSITION CONTROLLED GAUGE WHEELS ON A HARVESTING MACHINE HEADER THAT MOVE WITH A FEEDER HOUSE MOVE COMMAND

A header has a position controlled gauge wheel that is controlled using a position actuator. The position actuator is locked when the gauge wheel is in a selected position, relative to a mainframe of the header. An operator input, changing the position of the header, is detected and the position actuator is unlocked to accommodate movement of the header, based on the detected operator input signal.

Wing locking with hydraulic blocker valve

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 flat configuration while minimizing the amount of dynamic load imparted by the header on the combine during non-harvesting transport of the header.

Orificed check valve in wing circuit

A wing locking system for a harvesting header is provided. The wing locking system includes an accumulator, a fluid cylinder operably attached to a wing of the harvesting header, a hose fluidly connecting the accumulator and the fluid cylinder, and a valve operably disposed between the accumulator and the fluid cylinder. The valve includes a first selectable position configured to permit a first fluid flow rate between the accumulator and the fluid cylinder and a second selectable position configured to permit a second fluid flow rate from the accumulator to the fluid cylinder. The first fluid flow rate is greater than the second fluid flow rate.
