Abstract

An agricultural working vehicle includes a working tool, a drive assembly for raising and lowering the working tool and a control element that is deflected from a neutral position in different directions. A speed (v) at which the drive assembly moves the working tool is a continuous function of a deflection (a) of the control element.

Claims

1. An agricultural working vehicle, comprising:

a working tool (1),

a drive assembly for raising and lowering the working tool (1), and a control element (12) that is deflected from a neutral position (0) in different directions,

wherein a speed (v) at which the drive assembly moves the working tool (1) is a continuous function of a deflection (α

) of the control element (12).

2. The agricultural working vehicle according to claim 1, wherein the control element (12) is rotatable about an axis (16).

3. The agricultural working vehicle according to claim 2, wherein the control element (12) has a corrugated circumferential surface (17).

4. The agricultural working vehicle according to claim 2, wherein the axis (16) is oriented transversely to the direction of travel of the working vehicle.

5. The agricultural working vehicle according to claim 2, wherein the working tool (1) is raised upwardly, in the direction of travel via deflection of an exposed surface (17) of the control element (12) or both, and is lowered via deflection of the surface (17) opposite the direction of travel and/or downwardly.

6. The agricultural working vehicle according to claim 1, wherein the control element (12) is disposed on a multifunctional handle (6).

7. The agricultural working vehicle according to claim 6, wherein the multifunctional handle (6) comprises a gripping surface (9) oriented to support at least a portion of the palm of a driver'"'"'s hand resting in an operating position and wherein the control element (12) is reachable by a finger of the hand resting in the operating position.

8. The agricultural working vehicle according to claim 7, wherein a surface (18) of the multifunctional handle (6) adjoins an exposed surface (17) of the control element (12) in a flush manner.

9. The agricultural working vehicle according to claim 1, wherein the control element is fixed in the neutral position via locking means (20, 21, 22).

10. The agricultural working vehicle according to claim 1, wherein an interval (−

ε

, +ε

), in which the speed of the working vehicle (1) is zero, extends on either side of the neutral position (0).

11. The agricultural working vehicle according to claim 1, wherein the agricultural working machine comprises a combine harvester or a forage harvester.
