Abstract

A control apparatus for an agricultural machine operatively arranged in an operator'"'"'s cab proximate an operator having a multi-functional handle. The multi-functional handle has a gripping portion with a plurality of control elements. The control elements are operatively arranged such that the operator can reach the control elements with one or two fingers while holding the gripping portion. A selection/transfer element is used to select control elements to perform a first and a second control function. A display unit is used to display the function symbols of the selected function.

Claims

1. A device for control of an agricultural machine which is arranged in an operator'"'"'s cab in proximity to the operator, including a multi-function handle comprising a gripping portion having a plurality of control elements, the control elements being so constructed and arranged that they can be reached reliably with one or two fingers of a hand of the operator resting on the gripping portion, the control elements serving to control a first function of a first element of the machine, the device further comprising:

one of the control elements of the multi-function handle having a selection element having another setting for control of at least one further function of a second element of the machine such that said multifunction handle controls said first function of said first work element when said selection element is in a first position and said multifunction handle controls said at least one further function of said second work element when said selection element is in a second position.

6. The control device of claim 1 further comprising:

a display, said display being in operative communication with said selection element and said display being configured to display a currently selected work element.

7. The control device of claim 1 wherein said selection control is a switch.

8. The control device of claim 7 wherein said switch is selected from the group consisting of:

a rotary switch, a sliding switch, a rocker switch, and a toggle switch.

9. The control device of claim 7 wherein said switch has at least two positions.

10. The control device of claim 1 wherein said selection control includes functional symbols associated with each position of said selection control, said functional symbols corresponding to a work element selection.

11. The control device of claim 1 wherein said selection control includes functional symbols associated with each position of said selection control, said functional symbols corresponding to a function selection.

12. The control device of claim 1, wherein said selection control is a knurled wheel.

13. The control device of claim 1, wherein said positions of said selection control are discerned by touch.

14. The control device of claim 1, wherein said control further comprises a stop.

15. The control device of claim 11 or 12, wherein said functional symbols are illuminated.

16. The control device of claim 1 further comprising a control panel, said control panel including at least one of said plurality of control elements.

17. The control device of claim 1 wherein said first functions controlling said first work element are operated with the same control elements as said further functions of said second work elements.

18. The control device of claim 1 wherein said first functions of said first work element are controlled with different control elements from said further functions of said second work element.

2. In an agricultural machine having a plurality of work elements, each of said work elements having separate functions, said separate functions being selectively operable by a control element, a control apparatus configured for location in an operator'"'"'s cab in a position proximate the operator, the control apparatus comprising:

a multifunction handle having a gripping portion;

a first control element on said multifunction handle;

at least one other control element on said multifunction handle;

each of said control elements being adapted to operatively connect with at least one of said plurality of working elements of the agricultural machine to control one of said separate functions of said one work element;

a selection element having a first position wherein said first control element is operatively connected with one of said working elements such that use of said first control element controls one of said separate functions of said one of said working elements; and

said selection element having a second position wherein at least one other control element is operatively connected with another of said working elements such that use of said at least one other control element controls another one of said separate functions of said another of said work elements.

3. The control apparatus of claim 2 wherein when said selection element is in said second position, said first control element is operatively connected with another of said plurality of working elements such that use of said first control element remotely operates said another of said plurality of work elements.

4. The control apparatus of claim 4 wherein when said selection element is in said second position, said first control element is not operatively connected with said one of said plurality of work elements.

5. In an agricultural combine having a cutter bar, a cutter bar table, and a reel, a multifunction control, said multifunction control comprising:

a handle, said handle being moveable between positions, said movement of said handle being adapted to operatively connect to control one of a plurality of functions of one of said cutter bar, said cutter bar table and said reel;

at least one control button on said handle, said control button being moveable between positions, said movement of said control button being adapted to operatively connect to control another of one of said plurality of functions of one of said cutter bar, said cutter bar table or said reel,

a selection control on said handle, said selection control being adjustable between a first, a second and a third position such that when said selection control is in said first position said movement of said handle controls a first function of said cutter bar and said movement of said control button controls a second function of said cutter bar, and such that when said selection control is in said second position, said movement of said handle or said control button controls a first function of said cutter bar table, and such that when said selection element is in said third position, said movement of said handle controls a first function of said reel and said movement of said control button controls a second function of said reel.

19. The multi-function control of claim 5 wherein said plurality of functions of said cutter bar includes moving said cutter bar up and down and turning said cutter bar on and off, adjusting a transverse tilt of said cutter bar, and adjusting a cutting angle of said cutter bar.

20. The multi-function control of claim 5 wherein said plurality of functions of said reel include moving said reel up and down and moving said reel forward and backward.

21. The multi-function control of claim 5 wherein said plurality of functions of said cutter bar table include adjusting a length of said cutter bar table.

22. The multi-function control of claim 5 wherein said multi-function control is adapted to operatively connect to a roller hold down device and said plurality of functions includes pivoting said roller hold down device.

23. The multi-function control of claim 5 wherein said multi-function control is further adapted to operatively connect to a grain tank pipe and said plurality of functions include swinging said grain tank pipe.

24. The multi-function control of claim 5 wherein said multi-function control is adapted to operatively connect to a feed unit and said plurality of functions includes stopping said feed unit and reversing said feed unit.
