  • Patent number: 10779457
    Abstract: An agricultural tractor having an auxiliary control station located outside of the tractor cab. The auxiliary control station is used for the actuation of tractor components, e.g. hydraulic cylinders, when an operator is outside of the cab. The auxiliary control station has a user interface which allows the external controls of the auxiliary control station to be reassigned to operate different actuatable elements of the tractor, thereby providing for increased ease-of-use of the tractor when an operator is outside of the cab.

  • Patent number: 10687470
    Abstract: A grain cleaning system in a combine harvester including a frame, a chaffer sieve, and a lower sieve. A clean grain chute is located under the lower sieve to catch grain falling therefrom and is inclined to direct the caught grain to a clean grain trough. A tailings return chute is disposed under the clean grain chute and is configured to direct tailings to a tailings collection trough. A multi-configurable plate is mounted to the frame and positioned under a rear portion of the chaffer sieve. The plate is moveable between different operating positions. In a first operating position the plate is configured to guide material incident thereon to the tailings return chute. In a second operating position the plate is configured to guide material incident thereon to the clean grain chute.

  • Patent number: 10661800
    Abstract: A drivetrain for an agricultural vehicle and method for controlling the same. The drivetrain includes first and second driven axles with a variable pivot angle hydraulic motor connectable to drive the first axle through engagement of a first clutch mechanism. A further motor is connected to drive the second axle. In operation, the pivot angle of the variable pivot angle hydraulic motor is reduced with variation in a vehicle parameter value, such as transmission ratio or ground speed, to a point at which the pivot angle reaches zero at a first parameter value. With the pivot angle at zero and parameter value continuing to vary due to the drive of the further motor, the first clutch mechanism is disengaged at a second parameter value, with the first and second parameter values separated by an interval determined at least partly by an operating characteristic of the first clutch mechanism.

  • Patent number: 10645879
    Abstract: A combine harvester having a grain pan arranged to catch a crop stream, the grain pan being driven in an oscillating manner to convey the crop stream rearwardly to a rear edge. A cleaning unit including a fan for generating a cleaning airstream which is directed under the rear edge. The grain pan includes a floor profile which defines a transverse profile comprising ridges and troughs. The troughs provide a plurality of longitudinal channels, wherein the ridge-to-trough height increases in the direction of conveyance. Crop material conveyed by the grain pan experiences channels that deepen towards the rear edge of the pan.

  • Patent number: 10571196
    Abstract: A cooling package for a vehicle, such as an agricultural tractor, having a heat exchanger with a fan providing air flow and a charge air cooler assembly that airflow is routed through multiple times in order to cool a compressed charge of air. As the temperature rise experienced by the cooling airflow is relatively minor compared to the initial temperature of the compressed charge of air, the airflow is initially routed through an outlet-side portion of the charge air cooler to cool the compressed charge of air towards the outlet side of the charge air cooler, and subsequently routed through an inlet-side portion of the charge air cooler to cool the compressed charge of air towards the inlet side of the charge air cooler.

  • Patent number: 10526031
    Abstract: A fender assembly for a tractor, as well as a tractor having such a fender assembly. The fender assembly is constructed as first and second fender parts, connected via a rail. The rail has a partial spiral or helical shape. As a result, the second fender part is moveable on the rail along a path substantially parallel to a portion of the circumference of a wheel of the tractor, in a direction downwardly and outwardly relative to the first fender part. This provides a fender assembly allowing for improved access to tractor components located inboard of the fender assembly, as well as allowing for ease of access to the second fender part for an operator standing on the ground adjacent the tractor.

  • Patent number: 10512203
    Abstract: A tractor control system, which controls an operating condition of an implement attached to the tractor. The control system includes a sensing means providing a force signal which indicates the pull force necessary to pull an implement in a desired position; a control which receives the force signal; and means for measuring at least one parameter associated with the tractor mode and/or the implement mode and the implement position is adjusted to a new position when the force signal varies. The control system includes pre-determined values associated with certain tractor and/or implement modes. A measured parameter is compared with a pre-determined parameter value and if the measured parameter would result in an undesired movement of the implement, the force signal is deactivated, or the response to the force signal is deactivated to prevent undesired movement of the attachment.

  • Patent number: 10448574
    Abstract: A compression roll housing for an agricultural machine, having a side panel provided with at least one elongated aperture for receiving a shaft of a compression roll and allowing movement of the shaft within the aperture. The housing is provided with a cover plate which rotates about an axis parallel to the shaft and is provided with an indentation to partially surround the shaft. Movement of the shaft, such as along a longitudinal axis of the aperture, causes the plate to rotate to provide a cover across the aperture to prevent the escape of any material from the housing.
