The disclosure relates to a crop merger system for a harvester. The system includes a frame, first and second rollers mounted to the frame, and a belt disposed over the first and second rollers. The system includes a motor operably coupled to and configured to rotate the second roller. The system includes a controller configured to electronically receive as input a desired speed of the belt. The system includes a sensor configured to detect a measured characteristic associated with the crop merger system, and electronically transmit the measured characteristic to the controller. The controller is configured to determine a measured speed of the belt based on the measured characteristic, and if the desired speed and the measured speed are unequal, the controller is configured to regulate the motor to adjust a speed of the belt to be substantially equal to the desired speed.

An agricultural vehicle with a header including multiple row units each include a feed/snapping unit and a chopping unit. The header further includes a first power transmission shaft for driving the feed/snapping units, and a second power transmission shaft connected via a drivetrain to a drive at the agricultural vehicle. Each chopper unit includes a safety clutch and is connected via the safety clutch to the second power transmission shaft. At least one torque sensor is provided for the second power transmission shaft, drivetrain, or drive, which torque sensor is operationally connected to a torque fluctuation monitor configured to recognize a predetermined change in torque fluctuation indicating a safety clutch slip. The torque fluctuation monitor is operationally connected to a user interface for signaling the safety clutch slip.

A prescribed feedrate of material through the mobile harvesting machine and an actual feedrate of material through the mobile harvesting machine are detected, and a feedrate difference between the prescribed feedrate and the actual feedrate is identified. Wheel slippage of the mobile harvesting machine is also detected. Based on the feedrate difference between the prescribed feedrate and the actual feedrate and based on the detected wheel slippage, a speed control signal that controls speed of the mobile harvesting machine is generated.

A forage harvester has multiple working elements for carrying out a crop handling process, a drive system which is divided into a main drive train that includes mechanically driven working elements, and an auxiliary drive train that includes hydraulically driven working elements, a driver assistance system which comprises a memory for storing data and a computing device for processing data stored in the memory, as well as a graphical user interface. The working elements consist of at least one adjustable crop handler, at least one actuator system for adjusting and/or actuating the crop handler, and a control unit for controlling the actuator system. The working element is designed as an automatic adjuster whose mode of operation can be optimized by the driver assistance system. The driver assistance system feeds a throughput-proportional load signal, which can be determined by at least one sensor system, to the particular automatic adjuster.

In a draper harvesting head having a frame, a left side conveyor supported on the frame, a right side conveyor supported on the frame, a central conveyor supported on the frame and disposed between the left side conveyor and the right side conveyor, and a reciprocating knife fixed to the front of the frame and extending laterally across the frame, a method of controlling slippage between an endless conveyor belt of one of the left side conveyor and the right side conveyor and a crop mat carried on the endless conveyor belt is provided, including determining a speed of the endless conveyor belt and a speed of the crop mat; comparing a difference in the speed of the endless conveyor belt and the speed of the crop mat with a first threshold speed difference; and changing the speed of the endless conveyor belt based upon the step of comparing.

A sickle cutting system is mounted on a header for forward travel over ground having a standing crop thereon and includes a cutter bar with a plurality of knife guards and two opposed sickle bars driven in opposite phase with a drive system for driving the sickle bar through repeated cycles of reciprocating movement from start-up of the system through to a shut-down. The drive system includes a control device responsive to the sensor signals from both of the first and second drive systems for advancing or retarding one of the first and second drive systems so that a number of sensor signals obtained from the first drive system is continually maintained so as to be substantially equal to a number of sensor signals obtained from the second drive system to maintain the sickle bars in opposite phase.

A method for operating a harvester may include initially operating the harvester in a discharge harvesting mode such that harvested crops are conveyed to a distal end of an elevator of the harvester and subsequently discharged from the harvester through a discharge opening defined by a storage hopper located at the distal end of the elevator. The method also includes reducing an operating speed of the elevator and blocking the discharge opening defined by the storage hopper upon receipt of an operator input associated with operating the harvester in a storage harvesting mode. Additionally, the method includes actively adjusting the operating speed of the elevator based on a crop flow parameter of the harvester as the harvested crops expelled from the distal end of the elevator are being stored within a storage volume of the storage hopper.

A user device, that is remote from a combine harvester, communicates with the remote harvester to receive contextual information indicative of machine settings on the combine harvester. Remote view and control logic receives the contextual information from the combine harvester, along with image or video display information generated from an image capture device (such as a video camera or other image capture device) on the combine harvester. The contextual information is displayed, along with the video or image information on the remote user device.

In one aspect, a system for adjusting operating parameters of an agricultural harvester based on estimated crop volume values may include an image capture device configured to capture one or more images of the crop materials standing within the field prior to the crop materials being harvested by a harvester. The system may also include a controller communicatively coupled to the image capture device. The controller may be configured to estimate a crop volume value associated with a quantity of the crop materials transferred through the harvester based on the one or more images captured by the image capture device. Additionally, the controller may be further configured to initiate a control action associated with adjusting an operating parameter of the harvester based on a magnitude of the estimated crop volume value.

A harvesting machine includes a main frame having a main actuator; a cutting frame having a crop guiding surface including a plurality of slots extending in a direction of travel of crop over the crop guiding surface and a plurality of knives pivotally mounted below the crop guiding surface; an outer frame being pivotable around a common pivot axis and being connected to the actuator; an inner frame having a plurality of operating units, and a selector mechanism configured to selectively engage one or more of the plurality of operating units. The outer frame includes an axis for pivotally holding a plurality of levers, each lever being pivotally connected to an operating unit of each knife. Guides are provided for lateral movement of the crop guiding surface with the plurality of knives from an operating position into a servicing position and vice versa.
