20220061213 · 2022-03-03 ·

A work vehicle includes a chassis, and a work implement movably coupled to the chassis and configured to perform a field-engaging function. The work machine also includes an actuator coupled to the work implement and configured to adjust a position of the work implement relative to a ground surface. The work machine further includes a controller in communication with an output device and a communication module. The controller is configured to monitor a location of the work machine via the communication module. The controller is also configured to load a field map from a field map database, the field map identifying at least one impact event comprising a geotagged location. The controller is further configured to display an alert via the output device in response to the location of the work machine approaching within a predetermined distance from the geotagged location.

CALIBRATION OF HARVESTING HEAD HAVING A GROUND FORCE SENSING SYSTEM
20230389469 · 2023-12-07 ·

A method for dynamically operating a header float system of an agricultural vehicle having a header movably mounted to a frame by an actuator and a flotation adjustment system that relies on ground-contact force measurement. The method includes: determining an initial zero value load sensor output signal representative of an initial position of the header raised out of contact with the ground surface, calibrating the sensor with the initial zero value, operating the header to process a crop material, detecting a subsequent position of the header out of contact with the ground surface, determining a subsequent zero value representative of the subsequent position of the header, and re-calibrating the sensor with the subsequent zero value. Also, an agricultural vehicle having a header operated as described above.

Systems and methods for adjusting a flexible cutter bar assembly
11234367 · 2022-02-01 · ·

An agricultural system includes an arm configured to rotate about a pivot joint and to support a portion of a cutter bar assembly, a fluid-filled biasing member slidingly coupled to the arm, an actuator coupled to the fluid-filled biasing member, a fluid pressure sensor configured to measure a fluid pressure in the fluid-filled biasing member, and a controller communicatively coupled to the actuator. The controller is configured to receive an input signal from the fluid pressure sensor indicative of the fluid pressure and to output an output signal to instruct the actuator to adjust a connection point between the fluid-filled biasing member and the arm based on the input signal.

Height control system for a front harvesting attachment

A height control system for a front harvesting attachment, comprising a frame, at least one crop pick-up device, and a ground-conforming cutterbar which is situated on a plurality of supporting arms that can pivot about a horizontal axis and are articulated on the frame. The supporting arms can be pivoted, originating from a desired position to be set before the start of a harvesting operation, between an upper end position, which delimits a deflection of the supporting arms in the direction of the crop pick-up device, and a lower end position, wherein the upper end position has a first clearance and the lower end position has a second clearance from the desired position, wherein the desired position can be adapted, during the harvesting operation, to changing harvesting conditions and/or operating conditions depending on a deflection of the cutterbar, in order to minimize the first clearance and maximize the second clearance.

DRAPER HEADER WITH AUTOMATIC REEL TO CUTTER BAR CLEARANCE

A draper header for harvesting crops includes a header frame with a middle frame section pivotally coupled between a pair of side wing sections. A cutter bar assembly extends across a front portion of the header frame and is flexible with the side wing sections for cutting the crops to be harvested. A pair of crop pick-up reels are rotatably supported by center and outer reel support arms for engaging the crops to be harvested. A sensing system is operatively coupled to the header frame for detecting when at least one of the side wing sections pivots downwardly relative to the middle frame section. When the sensing system detects that at least one of the side wing sections pivots downwardly past a predetermined pivot angle, a down-stop cylinder is actuated to raise the crop pick-up reels, thereby preventing contact of the crop pick-up reels with the cutter bar assembly.

Cutter head with automatic setting of the reel finger orientation

A cutter head for a harvester, with a cutterbar for cutting crop from a field, a reel with reel fingers which is disposed above the cutterbar, and a cross conveyor for transporting the cut crop to a rear discharge opening. The reel includes reel arms that can be driven about a rotating axis, reel finger carriers supported on the reel arms so they can rotate about the lengthwise axes of the arms, with reel fingers mounted thereon, and an externally powered actuator connected to an electronic control unit for adjusting the rotary angle of the reel finger carrier relative to the reel arms.

COMBINE HEADERS WITH FOLD UP CUTTERBARS
20210259153 · 2021-08-26 ·

A draper header includes a draper frame and a reel arm. The reel arm is coupled to a reel and pivotally coupled to the draper frame. The draper header further includes a cutterbar pivotally coupled to the draper frame. The reel arm and the cutterbar are configured to pivot about the draper frame to adjust a side profile aspect ratio of the draper header from a first aspect ratio to a second aspect ratio. A height of the first aspect ratio is less than a height of the second aspect ratio, and a width of the first aspect ratio is greater than a width of the second aspect ratio.

ADJUSTABLE AUTOMATIC FLEX ARM LOCKOUT
20210274706 · 2021-09-09 · ·

A cutter bar lockout mechanism for a header of an agricultural vehicle. The cutter bar lockout mechanism includes a shaft having a first end that is coupled to a frame of the header, and a second end that is positioned either on, within or adjacent a cutter bar support arm (arm) of the header. An upper stop is either mounted to the shaft or forms part of the shaft and is configured to selectively interact with an upper surface of the arm. A lower stop is either mounted to the shaft or forms part of the shaft and is configured to selectively interact with a lower surface of the arm. The shaft is movable relative to both the frame and the arm between an unlocked position and a locked position.
