Abstract

A system for monitoring the displacement of a ground engaging tool of an agricultural implement includes a controller of the system may be configured to monitor a magnitude of a displacement defined between a current position of a ground engaging tool of the implement and a predetermined ground engaging tool position. The controller may also be configured to initiate a first control action when it is determined that the magnitude of the displacement of the ground engaging tool exceeds a first threshold displacement value. Moreover, the controller may further be configured to initiate a second control action when it is determined that the magnitude of the displacement of the ground engaging tool exceeds a second threshold displacement value, with the second threshold displacement value corresponding to a greater displacement relative to the predetermined ground engaging tool position than the first displacement threshold value.

First claim

What is claimed is:

1. A system for monitoring the displacement of a ground engaging tool of an agricultural implement, the system comprising:
an implement including a frame and a ground engaging tool pivotally coupled to the frame, the ground engaging tool configured to be biased to a predetermined ground engaging tool position relative to the frame;
a sensor configured to detect a parameter indicative of a current position of the ground engaging tool relative to the frame; and
a controller communicatively coupled to the sensor, the controller being configured to:
monitor a magnitude of a displacement defined between the current position of the ground engaging tool and the predetermined ground engaging tool position based on measurement signals received from the sensor;
initiate a first control action when the magnitude of the displacement of the ground engaging tool exceeds a first threshold displacement value; and
initiate a second control action when the magnitude of the displacement of the ground engaging tool exceeds a second threshold displacement value, the second threshold displacement value corresponding to a greater displacement relative to the predetermined ground engaging tool position than the first displacement threshold value.

2. The system of claim 1 , wherein the controller is further configured to initiate a third control action when the magnitude of the displacement of the ground engaging tool falls below the first threshold displacement value, the third control action being associated with increasing a ground speed of the implement.

3. The system of claim 1 , wherein the first control action corresponds to presenting an interface element within a user interface displayed to an operator of the implement that provides the operator with a visual indicator associated with the displacement of the ground engaging tool and the second control action corresponds to updating the interface element when the displacement of the ground engaging tool exceeds the second threshold displacement value.

4. The system of claim 1 , wherein the first control action corresponds to presenting an interface element within a user interface displayed to an operator of the implement that provides the operator with a visual indicator associated with the displacement of the ground engaging tool and the second control action is associated with reducing a ground speed of the implement.

5. The system of claim 1 , wherein the first control action corresponds to presenting an interface element within a user interface displayed to an operator of the implement that provides the operator with a visual indicator associated with the displacement of the ground engaging tool and the second control action is associated with adjusting a down pressure exerted on the ground engaging tool.

6. The system of claim 1 , wherein the controller is configured to identify a time period across which the displacement of the ground engaging tool exceeds at least one of the first threshold displacement value or the second threshold displacement value and compare the identified time period to the threshold time period.

7. The system of claim 1 , wherein the sensor comprises a rotary sensor coupled to one of the frame or the ground engaging tool and a sensor linkage coupled between the rotary sensor and the other of the frame or the ground engaging tool, the rotary sensor being configured to detect an angle between the frame and the ground engaging tool, the angle being indicative of the current position of the ground engaging tool relative to the frame.

8. The system of claim 1 , further comprising:
a fluid-driven actuator configured to adjust a down pressure exerted on the ground engaging tool based on a fluid pressure associated with the fluid-driven actuator.

9. The system of claim 8 , wherein the sensor comprises a pressure sensor configured to detect the fluid pressure associated with the fluid-driven actuator, the fluid pressure being indicative of the current position of the ground engaging tool relative to the frame.

10. The system of claim 1 , wherein the controller is further configured to generate a field map that visually identifies the monitored displacement of the ground engaging tool relative to the first threshold displacement value and the second threshold displacement value for a field traversed by the implement.

11. A method for monitoring a displacement of a ground engaging tool of an agricultural implement, the ground engaging tool being normally biased to a predetermined ground engaging tool position relative to a frame of the implement, the method comprising:
monitoring, with a computing device, a magnitude of a displacement defined between a current position of the ground engaging tool and the predetermined ground engaging tool position;
initiating, with the computing device, a first control action when the magnitude of the displacement of the ground engaging tool exceeds a first threshold displacement value; and
initiating, with the computing device, a second control action when the magnitude of the displacement of the ground engaging tool exceeds a second threshold displacement value, the second threshold displacement value corresponding to a greater displacement relative to the predetermined ground engaging tool position than the first displacement threshold value.

12. The method of claim 11 , further comprising:
initiating, with the computing device, a third control action when the magnitude of the displacement of the ground engaging tool falls below the first threshold displacement value, the third control action being associated with increasing a ground speed of the implement.

13. The method of claim 11 , wherein initiating the first control action comprises presenting an interface element within a user interface displayed to an operator of the implement that provides the operator with a visual indicator associated with the displacement of the ground engaging tool and initiating the second control action comprises updating the interface element when the displacement of the ground engaging tool exceeds the second threshold displacement value.

14. The method of claim 11 , wherein initiating the first control action comprises presenting an interface element within a user interface displayed to an operator of the implement that provides the operator with a visual indicator associated with the displacement of the ground engaging tool and initiating the second control action comprises reducing a ground speed of the implement.

15. The method of claim 11 , wherein initiating the first control action comprises presenting an interface element within a user interface displayed to an operator of the implement that provides the operator with a visual indicator associated with the displacement of the ground engaging tool and initiating the second control action comprises adjusting a down pressure exerted on the ground engaging tool.

16. The method of claim 11 , further comprising:
identifying, with the computing device, a time period across which the displacement of the ground engaging tool exceeds at least one of the first threshold displacement values or the second threshold displacement value; and
comparing, with the computing device, the identified time period to the threshold time period.

17. The method of claim 11 , further comprising:
generating, with the computing device, a field map that visually identifies the monitored displacement of the ground engaging tool relative to the first threshold displacement value and the second threshold displacement value for a field traversed by the implem
