  • Patent number: 10081340
    Abstract: A steering brake locking system for a vehicle, such as an agricultural tractor, has at least first and second adjacent steering brake pedals, and a locking pin arranged to selectively lock the pedals together. The locking pin and at least a portion of the first and second pedals are formed from a conductive material, such that an electrically conductive path is formed between the first and second pedals through the locking pin when the pin is used to lock the pedals together. The locking status of the pedals can be determined by measuring the electrical conductivity between the first and second pedals.

    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: 10023193
    Abstract: An agricultural vehicle and method of controlling the same are provided, the vehicle having a motive power unit providing a driving torque to at least one driven wheel and having at least one tire or track frictionally coupled with the periphery of the driven wheel. A vehicle operating parameter is controlled in dependence on the driving torque and a slippage characteristic relating the respective driving torque at which the frictional coupling between driven wheel and tire or track begins to slip for a range of vehicle operating parameter values. The operating parameter is suitably a tire pressure or track tension, and the control may involve reducing driving torque or increasing pressure/tension to prevent slipping.

  • Patent number: 9987581
    Abstract: There is described a HVAC pre-filter system for a vehicle. The pre-filter system acts to prevent relatively large or coarse debris from reaching a dedicated HVAC filter through the use of at least one pre-filter element, which is provided in at least one inlet/outlet connected to ambient air. The pre-filter system has an inlet to supply air to the HVAC system, and an outlet to allow for air to exit from a vehicle cab interior, and the inlet/outlet can be switched to be fluidly coupled with either the HVAC inlet or the cab outlet. Dependent on which inlet or outlet the inlet/outlet is coupled with, the flow direction in the inlet/outlet can be controlled. Accordingly, the pre-filter can be cleaned of accumulated dust and debris by reversing the direction of airflow through the inlet/outlet.

  • Patent number: 9883622
    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: 9864497
    Abstract: A method and system for assisting user selection of ballasting options for an agricultural vehicle when coupled to an agricultural implement. The user is presented with a selection menu of implement types, whereby each implement type defines operating ranges of discrete values for first, second and optionally third operational parameters of the vehicle, with the differing combinations defining a values subset. An optimal choice from the available ballasting options is made for each combination in the values subset, and a selection from the optimal choices based on prevalence or probability of occurrence is made and may be presented to the user. Operational parameters may include operating speed, loading due to implement weight and engine power.
