Abstract
A work vehicle includes a motor associated with selectable movement of a frame by a first operator control. The frame structurally carries a cab structure and a manipulating structure associated with an implement for performing work. The manipulating structure is selectably movable by a second operator control located in the cab structure. All control functions associated with positioning the implement with respect to three different rotational axes are manipulable using the second operator control.
Claims20
A work vehicle comprising:
- a frame supporting a manipulating structure coupled to an implement;
- an operator control, wherein rotation of the operator control about each of three control axes is configured to cause corresponding rotation of the implement about a respective one of three different rotational axes via a first hydraulic circuit and a second hydraulic circuit, the three different rotational axes comprise a first axis, a second axis, and a third axis, the first hydraulic circuit is configured to control pitching movement of the implement about the first axis, and the second hydraulic circuit is configured to respectively control tilting and yawing movement of the implement about the second and third axes;
- wherein the operator control is configured to manipulate all control functions associated with positioning the implement with respect to the three different rotational axes by controlling the first and second hydraulic circuits and without utilizing a switch to toggle between the tilting and yawing movements.
A work vehicle comprising:
- an operator control configured to move an implement of the work vehicle, wherein rotation of the operator control is configured to position the implement with respect to three different rotational axes via a first hydraulic circuit and a second hydraulic circuit of the work vehicle, rotation of the operator control about a first control axis is configured to cause a corresponding pitching movement of the implement about a first rotational axis via the first hydraulic circuit, rotation of the operator control about a second control axis is configured to cause a corresponding tilting movement of the implement about a second rotational axis via the second hydraulic circuit, rotation of the operator control about a third control axis is configured to cause a corresponding yawing movement of the implement about a third rotational axis via the second hydraulic circuit, and concurrent rotation of the operator control about the second and third control axes is configured to cause a concurrent tilting and yawing movement of the implement about the second and third rotational axes via the second hydraulic circuit.
A control system for a work vehicle comprising:
- an operator control configured to manipulate all control functions associated with positioning an implement of the work vehicle with respect to three different rotational axes, wherein the operator control comprises:
- a first continuous arm that extends from a first end to a second end that is configured to be disposed proximate to a frame of the work vehicle;
- and
- a second continuous arm that is nonrotatably coupled to the first end of the first continuous arm, and the second continuous arm extends generally orthogonally to the first continuous arm;
- wherein rotation of the second continuous arm about three control axes is configured to cause corresponding movement of the implement with respect to the three different rotational axes via only two hydraulic circuits, a first hydraulic circuit is configured to control pitching movement of the implement about a first axis of the three different rotational axes, and a second hydraulic circuit respectively is configured to control tilting and yawing movement of the implement about a second axis and a third axis of the three different rotational axes.
