Abstract

A depth control system for an agricultural implement includes a single pivot lever. Additionally, the depth control system is mounted to the single pivot lever. Further, the depth control system includes a gauge wheel pivotally coupled to a frame of the agricultural implement. The control system controls a height of the gauge wheel relative to the frame via movement of the single pivot lever while the gauge wheel is coupled to a front pivot gauge wheel assembly. Furthermore, the depth control system is configured to control the height of the gauge wheel relative to the frame via movement of the single pivot lever while the gauge wheel is coupled to a rear pivot gauge wheel assembly.

Claims

1. An agricultural implement, comprising:

a frame configured to selectively couple to a front pivot gauge wheel assembly and a rear pivot gauge wheel assembly;

a depth control system comprising;

a single pivot lever directly rotatably coupled to the frame;

a depth controller mounted to the single pivot lever, wherein the depth controller is configured to selectively interact with the front pivot gauge wheel assembly and the rear pivot gauge wheel assembly, and the rear pivot gauge wheel assembly and the front pivot gauge wheel assembly are each configured to selectively couple to the frame on opposing sides of an axis of rotation of a gauge wheel;

wherein the depth control system is configured to control a height of the gauge wheel relative to the frame via movement of the single pivot lever while the front pivot gauge wheel assembly is coupled to the frame and the depth controller is configured to interact with the front pivot gauge wheel assembly, and the depth control system is configured to control the height of the gauge wheel relative to the frame via movement of the single pivot lever while the rear pivot gauge wheel assembly is coupled to the frame and the depth controller is configured to interact with the rear pivot gauge wheel assembly.

2. The agricultural implement of claim 1, comprising a rear pivot rocker while the single pivot lever is coupled to the rear pivot gauge wheel assembly.

3. The agricultural implement of claim 2, wherein the rear pivot rocker is configured to interact with the gauge wheel.

4. The agricultural implement of claim 1, comprising a linkage system while the single pivot lever is coupled to the front pivot gauge wheel assembly.

5. The agricultural implement of claim 4, wherein the linkage system comprises a linkage system actuator and the linkage system actuator is configured to interact with a front pivot actuator to control the height of the gauge wheel relative to the frame.

6. The agricultural implement of claim 1, wherein moving the single pivot lever in a first direction results in increasing the height of the gauge wheel relative to the frame while the depth controller interacts with the front pivot gauge wheel assembly, and moving the single pivot lever in the first direction results in decreasing the height of the gauge wheel relative to the frame while the depth controller interacts with the rear pivot gauge wheel assembly.

7. The agricultural implement of claim 1, comprising a peg system and a spring, wherein the spring is configured to engage the single pivot lever with the peg system.

8. The agricultural implement of claim 1, wherein the depth controller comprises both a rear pivot rocker and a linkage system.

9. The agricultural implement of claim 8, wherein the rear pivot rocker and the linkage system are each independently removable from the depth controller.

10. The agricultural implement of claim 1, wherein at least one opener disc coupled to the frame of the agricultural implement remains stationary relative to the frame of the agricultural implement while the gauge wheel is movable relative to the frame of the agricultural implement.

11. A system for positioning a gauge wheel of an agricultural implement, comprising:

the gauge wheel pivotally coupled to a frame of the agricultural implement; and

a depth control system mounted on the frame of the agricultural implement, wherein the depth control system comprises;

a single pivot lever directly rotatably coupled to the frame of the agricultural implement; and

a depth controller comprising a rear pivot rocker, a linkage system, or a combination thereof, mounted to the single pivot lever, wherein the depth controller is configured to selectively interact with a rear pivot gauge wheel assembly and a front pivot gauge wheel assembly, the rear pivot gauge wheel assembly and the front pivot gauge wheel assembly are configured to selectively couple to the frame on opposing sides of an axis of rotation of the gauge wheel, the rear pivot rocker is configured to selectively interact with the rear pivot gauge wheel assembly to control a first height of the gauge wheel based on a position of the single pivot lever while the depth controller comprises the rear pivot rocker and the gauge wheel is coupled to the rear pivot gauge wheel assembly, and the linkage system is configured to selectively interact with the front pivot gauge wheel assembly to control a second height of the gauge wheel based on the position of the single pivot lever while the depth controller comprises the linkage system and the gauge wheel is coupled to the front pivot gauge wheel assembly.

12. The system of claim 11, wherein the front pivot gauge wheel assembly comprises a gauge wheel pivot in front of the axis of rotation of the gauge wheel.

13. The system of claim 11, wherein the rear pivot gauge wheel assembly comprises a gauge wheel pivot behind the axis of rotation of the gauge wheel.

14. The system of claim 11, comprising a peg system configured to receive the single pivot lever and to maintain the single pivot lever in a depth position.

15. The system of claim 14, wherein the single pivot lever maintains engagement with the peg system via a spring.

16. The system of claim 11, wherein the single pivot lever is disposed behind the gauge wheel, relative to a direction of travel of the agricultural implement.

17. A depth control system for an agricultural implement, comprising:

a single pivot lever directly rotatably coupled to a frame of the agricultural implement;

a rocker coupled to the single pivot lever; and

a linkage system coupled to the single pivot lever comprising a linkage system actuator and a linkage system arm;

wherein the rocker and the linkage system are each removable from the single pivot lever, the single pivot lever is configured to pivot to control the rocker and the linkage system, the rocker is configured to selectively interact with a rear pivot gauge wheel assembly to control a depth at which an opener disc generates a furrow while the rocker is coupled to the single pivot lever and the rear pivot gauge wheel assembly is coupled to the frame of the agricultural implement, and the linkage system is configured to selectively interact with a front pivot gauge wheel assembly to control a depth at which the opener disc generates the furrow while the linkage system is coupled to the single pivot lever and the front pivot gauge wheel assembly is coupled to the frame of the agricultural implement, wherein the rear pivot gauge wheel assembly and the front pivot gauge wheel assembly are configured to selectively couple to the frame on opposing sides of an axis of rotation of a gauge wheel.
