An agricultural vehicle including a chassis and a header connected to the chassis. The header includes a frame and a plurality of row units connected to the frame. Each row unit includes at least one gathering chain having a plurality of protuberances affixed thereto and a rotational path, and at least one hood connected to the frame. The header also includes a down crop gatherer mounted to the at least one hood and having a rotational path, and a drive unit mounted to the at least one hood, operably connected in between the at least one gathering chain and the down crop gatherer. The drive unit is configured for translating a respective movement of each protuberance as the plurality of protuberances rotate with the at least one gathering chain to drive the down crop gatherer.

The disclosure relates to agricultural systems. The systems have stalk sensor assemblies and/or data visualization systems. The stalk sensor assemblies are configured for assessing the size and other characteristics about crops, such as corn and other grains entering an agricultural implement, such as a harvester. The stalk sensor assemblies may use an estimation of the stalk perimeter to establish stalk size and therefore further features about the crop. The visualization system utilizes data from the stalk sensor assemblies to calculate and display relevant information about the crop.

A header for an agricultural vehicle includes: a header frame; a first deck plate carried by the header frame; a second deck plate carried by the header frame, the first deck plate and the second deck plate forming a gap therebetween defining a gap width and a width direction; a rotatable tube carried by the header frame and connected to at least one of the first deck plate and the second deck plate such that rotation of the rotatable tube adjusts the gap width; and a spring fixed to the rotatable tube and having at least one end captured by the second deck plate such that a force directed in the width direction acting on the second deck plate produces a spring force in the spring.

A system for modifying a row unit of a harvesting head, the system including at least one cutting disk, a right angle gear set configured for being drivingly connected to the cutting disk, and a drive shaft between a row unit gear box and the right angle gear set. The system may drive two counter-rotating cutting disks that can be positioned either at near the rear or the front of the row unit. A method for modifying the row unit includes removing existing stalk rolls and housings, installing a cover plate over a gearbox to which the housings were mounted, removing existing trash knives, drilling holes in the row unit frame for mounting the cutting disks, installing the cutting disks.

Systems, methods and apparatus for detecting stalks processed by a combine harvester, for measuring stalk diameters, and for displaying harvest metrics and yield data to a user based on stalk locations and stalk diameters.

A row crop header for an agricultural machine harvesting a crop having stalks, such as corn. The row crop header includes a frame, a first crop row divider mounted to the frame, and a second crop row divider mounted to the frame and spaced from the first crop row divider to define a space therebetween. A row unit is disposed at the space, wherein the row unit includes a deck assembly defining a gap, the deck assembly including a compliant deck configured to adjust the gap based on contact with the stalks of the crop. The compliant deck includes a plurality of overlapping plates having edges defining the gap where the edges are configured to move responsively to varying diameters of stalks. Crops are separated from the stalks upon contact with the overlapping plates. A gathering chain moves the separated crops toward a collector.

A stalk roll mountable to a header of an agricultural combine for rotation about a rotation axis during processing of plant stalks has an annular drum with detachable blades. The stack roll has a plurality of circumferentially spaced flutes extending in an axial direction of the rotation axis of the drum and projecting radially outwardly from the drum. The flutes define mounting surfaces along lengths of the flutes. A plurality of blades are attachable to the drum with multiple of the plurality of blades being attachable to the mounting surface of a common one of the flutes. Mounting hardware is configured to removably connect the blades to the mounting surfaces of the flutes.

In one aspect, a system for operating an agricultural harvester may include a sensor assembly configured to detect a parameter indicative of an operating line of the harvester. The system may also include a controller configured to monitor the operating line of the harvester based on measurement signals received from the sensor assembly when the harvester is operated in a first operating mode. The controller may also be configured to determine a differential between the operating line and a predetermined guidance line of the harvester. Furthermore, the controller may be configured to update a stored correction value based on the determined differential. Additionally, when the harvester is switched from the first operating mode to a second operating mode, the controller may be configured to adjust a location of the predetermined guidance line based on the stored correction value.

In one aspect, a system for operating an agricultural harvester may include a sensor assembly having a base member pivotably coupled to a first row divider of the harvester. The sensor assembly may also include first and second arms extending outwardly from the base member along opposite sides of a centerline of the first row divider. The system may further include a controller communicatively coupled to the sensor assembly. The controller may be configured to monitor the distance between the first and second arms based on measurement signals received from the sensor assembly. Furthermore, the controller may be further configured to switch the harvester from a first operating mode to a second operating mode when it is determined that the monitored distance has exceeded a predetermined distance threshold.

A header of a combine harvester is provided. The header includes a belt conveyor configured to direct a movement of harvested crop material toward a feederhouse of the combine harvester. The belt conveyor is located adjacent an inlet of the feederhouse. The belt conveyor includes at least one protrusion extending radially from the belt conveyor that helps direct movement of harvested crop material toward the feederhouse.
