Abstract
An agricultural machine comprises a carrier vehicle and an attachment is disclosed. The attachment is pivotably guided on the carrier vehicle about an axis extending in the direction of travel of the carrier vehicle. To the right and left of the axis, a support wheel is connected to the attachment via a damped, compressible arm. A control circuit is configured to decide whether a pivoting motion of the attachment about the axis is or is not desirable and, in the case that the pivoting motion is desirable, the arm that is compressed by the pivoting motion is switched from a strongly dampened compressible state to a substantially undampened state.
Claims20
An agricultural machine comprising:
- a carrier vehicle and an attachment that is pivotably guided on the carrier vehicle about an axis extending in a direction of travel of the carrier vehicle;
- at least two support wheels connected, via respective dampened compressible arms, on both sides of the axis to the attachment;
- at least one sensor configured to generate sensor data indicative of operation of the attachment;
- and
- a control circuit configured to:
- determine, based on the sensor data, whether to modify a pivoting motion of the attachment;
- responsive to determining to modify the pivoting motion of the attachment:
- determine a change to compressibility of one of the compressible arms;
- and
- send at least one command to change the compressibility of the one of the compressible arms in order to change its compressible state.
An agricultural carrier vehicle for use in combination with an attachment, the attachment being pivotably guided on the agricultural carrier vehicle about an axis extending in a direction of travel of the agricultural carrier vehicle, the agricultural carrier vehicle comprising:
- a control circuit configured to:
- receive, from at least one sensor, sensor data indicative of operation of the attachment, the attachment including at least two support wheels connected, via respective dampened compressible arms, on both sides of the axis to the attachment;
- determine, based on the sensor data, whether to modify a pivoting motion of the attachment;
- responsive to determining to modify the pivoting motion of the attachment:
- determine a change to compressibility of one of the compressible arms;
- and
- send at least one command to change the compressibility of the one of the compressible arms in order to change its compressible state.
