Abstract

A feedback assembly for a harvester includes a chassis, at least one rod coupled to the chassis, and at least one tine rotatably coupled to the at least one rod. The at least one tine defines an elongated body including a linear section extending from the at least one rod, and an angled section extending at an angle from the linear section. The at least one tine configured to hang substantially perpendicularly relative to a direction of travel of the harvester when in a non-actuated position and configured to rotate away from the direction of travel of the harvester when in an actuated position.

First claim

The invention claimed is:

1. A mower, comprising:
a chassis;
a cutterbar connected to the chassis;
a feedback assembly connected to the chassis rearward of the cutterbar, the feedback assembly comprising:
at least one rod coupled to the chassis; and
at least one tine rotatably coupled to the at least one rod, the at least one tine defining an elongated body comprising a linear section extending from the at least one rod;

at least one sensor coupled to at least one of the chassis or the-at least one rod, the at least one sensor configured for detecting the quality of operation of the at least one blade assembly by detecting at least one of a rotational position or magnitude of rotation of the at least one tine relative to the at least one rod.

2. The mower of claim 1 , wherein the at least one rod is fixedly coupled to the chassis.

3. The mower of claim 1 , wherein the at least one tine is configured to hang substantially perpendicularly relative to a direction of travel of the chassis when in a non-actuated position.

4. The mower of claim 1 , wherein the at least one tine is independently rotatable relative to the at least one rod.

5. The mower of claim 1 , wherein the at least one tine is configured to rotate away from a direction of travel of the chassis when in an actuated position.

6. The mower of claim 1 , wherein the tine includes an angled section that extends from the linear section in a direction away from a direction of travel of the chassis.

7. The mower of claim 1 , wherein the elongated body of the at least one tine comprises an elongated rod defining a uniform diameter.

8. The mower of claim 1 , wherein the linear section defines about 75% of an overall length of each tine, and the angled section defines about 25% of the overall length of each tine.

9. The mower of claim 1 , wherein the angle between the angled section and the linear section is from about 15 degrees to about 45 degrees.

10. The mower of claim 1 , wherein the at least one tine is aligned rearward of the intersection of at least one of diverging discs or converging discs of the cutterbar.

11. The mower of claim 1 , wherein the at least one sensor comprises at least one or a combination chosen from: an optical sensor, a photoelectric sensor, or a rotary potentiometer.

12. The mower of claim 1 , further comprising a seal disposed over the at least one sensor.

13. The mower of claim 1 , further comprising a housing disposed over the at least one rod, the at least one tine rotatably disposed relative to the housing.

14. The mower of claim 1 , wherein the at least one rod comprises a left-hand rod and a right-hand rod connected at a central support, the at least one tine comprises a left hand tine and a right tine and the at least one sensor comprises a left hand sensor and aright hand sensor, wherein the left hand tine is coupled to the left hand rod, the right hand tine is coupled to the right hand rod and the left hand sensor positioned to determine the position of the left hand time and the right hand sensor positioned to determine the position of the right hand tine.

15. A harvester, comprising:
a frame;
first and second wheels rotatably coupled to the frame;
a cutterbar connected to the frame and defining a cutting width; and
a feedback assembly positioned rearward of the cutterbar, the feedback assembly

comprising:
a chassis;
at least one rod coupled to the chassis and extending across the majority of the cutting width; and
at least one tine rotatably coupled to the at least one rod, the at least one tine defining an elongated body comprising a linear section extending from the at least one rod, and an angled section extending at an angle from the linear section;
at least one sensor configured to detect at least one of a rotational position or magnitude of rotation of the at least one tine relative to the at least one rod.

16. The harvester of claim 15 , comprising at least one conditioner rotatably coupled to the frame.

17. The harvester of claim 15 , comprising a lifting assembly operably coupling the feedback assembly to the frame, wherein the lifting assembly comprises an actuator configured to control the vertical position of the feedback assembly relative to a ground surface.

18. The harvester of claim 15 , wherein the at least one cutterbar assembly comprises at least one blade assembly rotatably coupled to the frame.

19. A harvester, comprising:
a frame;
a plurality of cutting assemblies connected to the frame and defining a cutting width;
a feedback assembly for detecting the quality of operation of at least one of the plurality of cutting assemblies, the feedback assembly comprising:
a chassis connectable to the frame;

at least one rod coupled to the chassis rearward of the plurality of cutting assemblies and extending across a majority of the cutting width; and
at least one tine rotatably coupled to the at least one rods;
wherein the at least one tine is configured to hang substantially perpendicularly relative to a direction of travel of the frame when in a non-actuated position; and

wherein the at least one tine is configured to rotate away from the direction of travel of the chassis when in an actuated position;
at least one sensor configured to detect at least one of a rotational position or magnitude of rotation of the at least one tine relative to the at least one rod.
