  • Publication number: 20230240169
    Abstract: An agricultural machine having an auxiliary vehicle with a driver's workplace, an agricultural vehicle with a loading ramp for transporting the auxiliary vehicle and a control unit. The agricultural machine is operable in a combined configuration in which the auxiliary vehicle is placed on the loading ramp or in a separated configuration in which the auxiliary vehicle is removable from the loading ramp. The driver's workplace has a human machine interface for controlling a manual driving function of the agricultural vehicle and a manual driving function of the auxiliary vehicle. The control unit is configured to disable the manual driving function of the auxiliary vehicle if the combined configuration of the agricultural machine is present and to enable the manual driving function of the auxiliary vehicle if the separated configuration of the agricultural machine is present.

  • Patent number: 11110771
    Abstract: There is described a wheel axle for an agricultural vehicle such as a combine harvester. The wheel axle has at least one wheel suspension (32a) arranged to maintain a wheel axle parallel to the supporting surface, through use of a linkage arrangement (36, 38, 40) which is pivotally coupled to the axle frame (30). The configuration of the wheel suspension allows for the wheel axis to passively follow the surface profile, as any loads transmitted through the wheel carrier act to level out the wheel suspension to align with the underlying surface. As the wheel axle is adjusted to lie parallel with the underlying surface, accordingly the ground-contacting surface area of the associated wheels is maximised.

  • Patent number: 10986776
    Abstract: In a grain unloading system for a combine harvester a grain bin includes a frame, the frame has a floor with a trough. An unloading auger is disposed at least partially within the trough. An auger cover at least partially covers the auger. The auger cover has a hat for a top portion of the auger cover and a pair of gates movable between the hat and locations on the floor that are proximal to the trough. A gate adjustment structure is coupled to the pair of gates to move the pair of gates relative to the auger. A control system is coupled to the gate adjustment structure and configured to control the gate adjustment structure.

  • Patent number: 10932410
    Abstract: An unloading system for a combine harvester having a belt-driven unloading auger assembly and a spill saver door mounted proximate to a discharge end of the unloading auger assembly. Engagement of the belt drive is controlled by a first hydraulic cylinder. Opening of the spill saver door is controlled by a second hydraulic actuator. The first and second hydraulic cylinders are hydraulically connected in parallel.

  • Publication number: 20200178468
    Abstract: A fan unit for a combine harvester cleaning unit having at least two fan wheels, each fan wheel being enveloped by a fan wheel housing having at least one inlet segment and at least one outlet segment extending tangentially from the fan wheel housing, each outlet segment being connected to a common channel section and each vertical side wall of an outlet segment adjacent another outlet segment is inclined toward the vertical side wall of the adjacent outlet segment. This construction has as an advantage that it allows for improved flow characteristics of the air exiting the outlet thereby permitting better separation of MOG and grain in the sieves of the cleaning unit of which the fan unit is a part.

  • Patent number: 9788486
    Abstract: A grain header has a frame with a cutter bar affixed to the frame. A sub-frame is pivotably coupled to the frame and a mower cutter bar is coupled to the sub-frame. A swather is coupled to the sub-frame and arranged rearward relative to the mower cutter bar. A deflector is disposed between the cutter bar and the mower cutter bar. The deflector is moveable between a raised position in which the deflector permits crop material cut by the mower cutter bar to pass onto the swather, and a lowered position in which the deflector inhibits crop material cut by the mower cutter bar from passing onto the swather.

  • Patent number: 9446658
    Abstract: An agricultural tractor comprises an engine and a cooling package supported in front of a cab. The cooling package comprises a radiator and fan disposed between the engine and cab, the radiator having a major surface which is aligned longitudinally so that an airflow forced through the radiator by the fan is generally transverse with respect to the tractor's forward direction of travel. The orientation of the radiator provides for a narrower front end installation which improves the driver's field of view and relaxes limitations on steering angles and cooling package size.
