Abstract

A harvesting apparatus includes a crop conditioning element and an associated hood for conditioning crop material. The hood is moveably mounted to a frame of the harvesting apparatus, at a position located above the crop conditioning element. The hood is moveably mounted to the frame for movement toward and away from the crop conditioning element to adjust a gap therebetween. A swathboard is attached to and moveable with the hood. The swathboard is moveable relative to the hood between a plurality of operating positions. The swathboard is operable to maintain its position relative to the hood during movement with the hood toward and away from the crop conditioning element to form a consistent swath while moving the hood relative to the crop conditioning element to adjust the gap therebetween.

First claim

What is claimed is:

1. A harvesting apparatus for an agricultural machine, the harvesting apparatus comprising:
a frame;
a cutting mechanism coupled to the frame and operable to cut crop;
a crop conditioning element coupled to the frame and positioned relative to the frame at a location rearward of the cutting mechanism for receiving crop from the cutting mechanism;
a hood moveably mounted to the frame above the crop conditioning element for movement toward and away from the crop conditioning element;
an adjustment mechanism attached to and moveable with the hood;
a swathboard attached to and moveable with the hood during movement of the hood toward and away from the crop conditioning element, wherein the swathboard is rotatably attached to the hood for movement about a swathboard axis relative to the hood between a plurality of operating positions of the swathboard; and
wherein the adjustment mechanism includes a connecting link attached to the swathboard and operable to rotate the swathboard relative to the hood about the swathboard axis between each of the plurality of operating positions of the swathboard, wherein the connecting link is configured to maintain each of the plurality of operating positions of the swathboard relative to the hood during movement of the hood toward and away from the crop conditioning element.

2. The harvesting apparatus set forth in claim 1 , wherein the adjustment mechanism includes a handle rotatable about a handle axis.

3. The harvesting apparatus set forth in claim 2 , wherein the adjustment mechanism includes a support bracket interconnecting the hood and the handle, wherein the support bracket is fixedly attached to the hood and rotatably supports the handle.

4. The harvesting apparatus set forth in claim 2 , wherein the connecting link extends between and interconnects the handle and the swathboard.

5. The harvesting apparatus set forth in claim 4 , wherein the connecting link is attached to the handle at an upper connection location that is radially offset from the handle axis, and wherein the connecting link is attached to the swathboard at a lower connection location that is radially offset from the swathboard axis.

6. The harvesting apparatus set forth in claim 2 , wherein the adjustment mechanism includes a position plate defining a plurality of notches, with the handle engaged with a respective one of the plurality of notches to position the swathboard in a respective one of the plurality of operating positions.

7. The harvesting apparatus set forth in claim 6 , wherein the position plate is attached to and moveable with the hood.

8. The harvesting apparatus set forth in claim 1 , further comprising an actuating system interconnecting the frame and the hood, wherein the actuating system is controllable to move the hood toward and away from the crop conditioning element.

9. The harvesting apparatus set forth in claim 8 , wherein the actuating system includes a multiple linkage system having a plurality of links interconnected for moving the hood.

10. A crop conditioning system for a harvesting apparatus, the crop conditioning system comprising:
a crop conditioning element;
a hood moveable toward and away from the crop conditioning element to define a gap therebetween;
an adjustment mechanism attached to and moveable with the hood;
a swathboard attached to and moveable with the hood during movement of the hood toward and away from the crop conditioning element, wherein the swathboard is rotatably attached to the hood for movement about a swathboard axis relative to the hood between a plurality of operating positions of the swathboard;
wherein the adjustment mechanism includes a connecting link attached to the swathboard and operable to rotate the swathboard relative to the hood about the swathboard axis between each of the plurality of operating positions of the swathboard, wherein the connecting link is configured to maintain each of the plurality of operating positions of the swathboard relative to the hood during movement of the hood toward and away from the crop conditioning element.

11. The crop conditioning system set forth in claim 10 , wherein the adjustment mechanism includes a handle rotatable about a handle axis.

12. The crop conditioning system set forth in claim 11 , wherein the adjustment mechanism includes a support bracket interconnecting the hood and the handle, wherein the support bracket is fixedly attached to the hood and rotatably supports the handle.

13. The crop conditioning system set forth in claim 11 , wherein the connecting link extends between and interconnects the handle and the swathboard, wherein the connecting link is attached to the handle at an upper connection location that is radially offset from the handle axis, and wherein the connecting link is attached to the swathboard at a lower connection location that is radially offset from the swathboard axis.

14. The crop conditioning system set forth in claim 11 , wherein the adjustment mechanism includes a position plate attached to and moveable with the hood, wherein the position plate defines a plurality of notches, with the handle engaged with a respective one of the plurality of notches to position the swathboard in a respective one of the plurality of operating positions.

15. A crop conditioning system for a harvesting apparatus, the crop conditioning system comprising:
a crop conditioning element;
a hood moveable toward and away from the crop conditioning element to define a gap therebetween;
a swathboard attached to and moveable with the hood, wherein the swathboard is operable to maintain an operating position relative to the hood during movement with the hood toward and away from the crop conditioning element;
wherein the swathboard is rotatably attached to the hood for movement about a swathboard axis between a plurality of operating positions relative to the hood;
an adjustment mechanism attached to and moveable with the hood, wherein the adjustment mechanism is coupled to the swathboard and operable to rotate the swathboard relative to the hood and about the swathboard axis between each of the plurality of operating positions; and
wherein the adjustment mechanism includes a handle rotatable about a handle axis, and a connecting link extending between and interconnecting the handle and the swathboard, wherein the connecting link is attached to the handle at an upper connection location that is radially offset from the handle axis, and wherein the connecting link is attached to the swathboard at a lower connection location that is radially offset from the swathboard axis.
