A tensioning bar assembly for a tensioning assembly of a drive system of an agricultural machine includes a longitudinal bar having a top end, a bottom end, and a threaded portion. An attachment device is coupled to the top end to attach to a tensioning arm. A compression spring is located around a portion of the longitudinal bar. A first spring retainer engages with and retains a first end of the spring. A first locking nut fits to the threaded portion of the bar and retains the first spring retainer longitudinally in place relative to the bar. The longitudinal bar is rotationally freely coupled to the attachment device to permit free axial rotation of the bar about its longitudinal axis relative to the attachment device, and an engagement head is attached to and located at or proximate the bottom end of the longitudinal bar for engagement with a tool.

A threshing state management system includes an image capture unit 80 that captures an image of a threshed material threshed by a threshing apparatus, a state detection neural network 72 that outputs a threshing processing state in the threshing apparatus based on image input data generated based on the captured image from the image capture unit 80, a parameter determination unit 73 that determines a control parameter of the threshing apparatus based on the threshing processing state, and a threshing control unit TU that controls the threshing apparatus based on the control parameter.

An agricultural harvester includes an IC engine, a grain tank, and a fluid cooling system for at least one component onboard the agricultural harvester. The fluid cooling system has a cooling package positioned between the IC engine and the grain tank. The cooling package includes a housing, and a plurality of cooling units arranged in a side-to-side manner within the housing, transverse to a fore-aft direction of the harvester.

An agricultural harvester with crop residue spreaders distributing crop residue laterally. Each crop residue spreader has a plurality of radially extending bats rotatable within a housing for directing residue from an axially directed inlet radially outward through an outer outlet. The housing has an outer wall with a height that increases axially in a uniform fashion around the periphery to minimize if not eliminate recirculation of residue to the inlet.

Disclosed is an articulated harvesting combine of a forward power processing unit (PPU) and a rear grain cart, wherein the PPU carries dual axially mounted engines with oppositely opposed crankshafts with one toward the rear grain cart and the other engine away from the rear grain cart, there being no comingling of flywheel output power flow between the two engines.

Described herein are methods and harvesters for adjusting settings of a harvester. In one embodiment, a computer Implemented method includes capturing, with at least one image capture device that is located on the harvester, images of a field view of an unharvested region to be harvested, analyzing the captured images to determine crop information for a crop of a harvested region that is adjacent to the unharvested region, and adjusting settings or operating parameters of the harvester for the unharvested region based on the crop information for the crop of the harvested region.

A combine harvester includes a feederhouse mounted to a chassis adapted at a front end to support a crop gathering header, a duct mounted on the feederhouse that is connected to a crop conveying passage of the feederhouse via a set of suction openings, a set of vent openings in the duct, each of the vent openings having a respective closure element movable between an open position and a closed position, and a fan arranged within the duct that can be operated in a first direction to create a suction airflow to extract dust from the crop conveying passage and discharge the dust through the duct, and in a second direction to create a blowing airflow to open the closure elements and vent air through the vent openings.

A residue spreader for receiving crop residue from a residue chopper of a combine harvester and for spreading crop residue onto the ground. The spreader includes a spreader body having an inlet and an outlet side, and left and right groups of deflectors, each deflector pivotally mounted on the spreader body in juxtaposed position and configured to laterally deflect the crop residue between the inlet side and the outlet side. The deflectors within each group are coupled together for pivoting movement in unison. A distribution actuator has an actuator body and an actuator element and the actuator body is mounted to the spreader body. The actuator element is coupled to both the left and right groups of deflectors by respective pivoting links. The actuator body is adjustably mounted to the spreader body. An adjustment actuator is connected to the actuator body to control movement of the actuator body with respect to the spreader body to adjust a spread width.

An agricultural harvester includes one or more actuators configured to move a crop unloading tube of the harvester relative to a frame of the harvester. Additionally, the agricultural harvester includes a sensor configured to capture data indicative of a presence of the crop receiving vehicle within a crop unloading zone of the agricultural harvester. Moreover, the agricultural harvester includes a computing system communicatively coupled to the sensor. As such, the computing system configured to determine when the crop receiving vehicle is present within the crop unloading zone based on the data captured by the sensor. In addition, when it is determined that the crop receiving vehicle is present within crop unloading zone, the computing system is configured to control an operation of the one or more actuators such that the crop unloading tube is moved relative to the frame from a current position to a predetermined crop unloading position.
