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.

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.

A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

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.

A residue handling system for an agricultural harvester includes a chopper that is positionable within a straw hood of the combine harvester and a seed mill that is mounted directly to the chopper. The chopper has projecting elements for chopping straw within the straw hood as the chopper rotates. The seed mill includes a rotatable rotor that is at least partially positioned within a concave. The rotor and the chopper are connected or unitized so as to rotate together.

An agricultural harvesting machine includes crop processing functionality configured to engage crop in a field, perform a crop processing operation on the crop, and move the processed crop to a harvested crop repository, and a control system configured to identify a weed seed area indicating presence of weed seeds, and generate a control signal associated with a pre-emergence weed seed treatment operation based on the identified weed seed area.

A residue collector is operable to receive residue from a combine harvester during a training harvesting operation. The residue collector includes a residue separator for separating the processed residue into a first portion and a second portion based on a property of the processed residue; one or more weight sensors for directly or indirectly determining the weight of the first portion and the second portion; and a controller configured to determine a quality factor for the processed residue based on the determined weight of the first portion in relation to the weight of the second portion.

An agricultural residue depositing apparatus includes a human-controllable mobile vehicle that is capable of generating agricultural residue and depositing it on a ground surface over which the mobile vehicle is moveable. The vehicle includes an interface device that is capable of generating one or more output that is interpretable by a human operator. The apparatus include sensors of agricultural residue deposited by the mobile vehicle and processors to which the sensors are operatively connected. The processors are additionally operatively connected to the interface device such that the interface device generates one or more outputs, based on one or more signals generated by the one or more sensors, of or relating to agricultural residue deposited by the mobile vehicle. The processors are capable of adding human-interpretable augmentation to the outputs indicating one or more parameters of or relating to the deposition of residue.

A spreader system for use in an agricultural harvester having a threshing system and a cleaning system. The spreader system includes a chopper for the chopping of straw from the threshing system and a chaff spreader system and a straw spreader system. The chaff spreader system is configured to receive a flow of chaff from the cleaning system; and the straw spreader system is configured to receive a flow of straw from the chopper. The chaff spreader system is configured to emit a chaff airflow stream in a first flow path, and the straw spreader system is configured to emit a straw airflow stream in a second flow path. The first flow path and the second flow path intersect at a place of confluence apart from the chaff spreader system and the straw spreader system.

A spreader system of an agricultural vehicle for spreading crop residue over a field includes a first spreader device including a plurality of first paddles configured to rotate about a first axis to define a first spread path; and a second spreader device including a plurality of second paddles configured to rotate about a second axis to define a second spread path. The second spreader device and the first spreader device are located side-by-side. The spreader system further includes deflector that include a first deflector portion for deflecting the first spread path and a second deflector portion for deflecting the second spread path. The spreader further includes a deflector driver connected to the deflector. The deflector driver is configured to move the first deflector portion and the second deflector portion of the deflector in a direction generally parallel to the first axis or the second axis in an oscillating pattern.
