Abstract

A wheel adjustment system for an agricultural implement includes a controller having a processor and a memory. The processor is configured to receive a first signal indicative of a ground speed of the agricultural implement, receive a second signal indicative of a desired position of a wheel of the agricultural implement, receive a third signal indicative of a current position of the wheel of the agricultural implement, and output a control signal to adjust a position of the wheel of the agricultural implement based on the first signal, the second signal, and the third signal, wherein a rate of adjustment of the position of the wheel varies based on the first signal.

First claim

The invention claimed is:

1. A wheel adjustment system for an agricultural implement, comprising:
a controller having a processor and a memory, wherein the processor is configured to:
receive a first signal indicative of a ground speed of the agricultural implement;
receive a second signal indicative of a desired position of a wheel of the agricultural implement;
receive a third signal indicative of a current position of the wheel of the agricultural implement; and
output a control signal to adjust a position of the wheel of the agricultural implement based on the first, second, and third signals, wherein a rate of adjustment of the position of the wheel varies based on the first signal.

2. The system of claim 1 , wherein the processor is configured to receive a fourth signal indicative of a weight of the agricultural implement, and the rate of adjustment of the position of the wheel varies based on the fourth signal.

3. The system of claim 2 , comprising a load cell configured to be coupled to the agricultural implement, wherein the load cell is configured to monitor the weight of the agricultural implement and to provide the fourth signal to the processor.

4. The system of claim 1 , comprising a seat switch configured to be coupled to a seat of the agricultural implement, wherein the seat switch is configured to monitor an operator's presence in the seat and to provide a fourth signal indicative of the operator's presence in the seat to the processor, and the processor is configured to block adjustment of the position of the wheel of the agricultural implement if the fourth signal indicates that the operator is not present in the seat.

5. The system of claim 1 , wherein the processor is configured to receive a fourth signal indicative of a height of a boom of the agricultural implement, and the rate of adjustment of the position of the wheel varies based on the fourth signal.

6. The system of claim 1 , wherein the processor is configured to cause a multi-colored indicator to illuminate with a first color during adjustment of the position of the wheel and to illuminate with a second color, different from the first color, when the current position of the wheel corresponds to the desired position of the wheel.

7. The system of claim 1 , comprising a touchscreen display that is configured to enable an operator to input the desired position of the wheel.

8. The system of claim 7 , wherein the touchscreen display is configured to provide numerical indications of the desired position of the wheel and of the current position of the wheel.

9. The system of claim 1 , wherein the rate of adjustment increases proportionally with speed while the agricultural implement travels between 0.5 and 5 miles per hour.

10. The system of claim 1 , wherein the controller is configured to provide a speed control signal to a speed control system of the agricultural implement to limit the ground speed of the agricultural implement during adjustment of the position of the wheel.

11. The system of claim 1 , comprising a position sensor integrated within an actuator that is configured to drive the wheel laterally relative to a frame of the agricultural implement, wherein the position sensor is configured to provide the third signal to the processor.

12. A wheel adjustment system for an agricultural implement, comprising:
a controller having a processor and a memory, wherein the processor is configured to:
receive a first signal indicative of a ground speed of the agricultural implement;
receive a second signal indicative of a desired position of a wheel of the agricultural implement;
receive a third signal indicative of a current position of the wheel of the agricultural implement;
receive a fourth signal indicative of a weight of the agricultural implement; and
output a control signal to adjust a position of the wheel of the agricultural implement based on the first, second, third, and fourth signals.

13. The system of claim 12 , wherein the control signal causes a rate of adjustment of the position of the wheel to vary based on the first and fourth signals.

14. The system of claim 12 , comprising a load cell configured to be coupled to the agricultural implement, wherein the load cell is configured to monitor the weight of the agricultural implement and to provide the fourth signal to the processor.

15. The system of claim 14 , wherein the processor is configured to receive a fifth signal indicative of a height of a boom of the agricultural implement, and the control signal varies based on the fifth signal.

16. The system of claim 12 , wherein the processor is configured to cause a multi-colored indicator to illuminate with a first color during adjustment of the position of the wheel and to illuminate with a second color, different from the first color, when the current position of the wheel corresponds to the desired position of the wheel.

17. A method of operating a wheel adjustment system for an agricultural implement, comprising using a controller having a processor and a memory to:
receive a first signal indicative of a ground speed of the agricultural implement;
receive a second signal indicative of a desired position of a wheel of the agricultural implement;
receive a third signal indicative of a current position of the wheel of the agricultural implement;
receive a fourth signal indicative of a weight of the agricultural implement; and
output a control signal to adjust a position of the wheel of the agricultural implement based on the first, second, third, and fourth signals.

18. The method of claim 17 , comprising, using the controller, varying a rate of adjustment of the position of the wheel based on the first and the fourth signals.

19. The method of claim 17 , comprising, using the controller, instructing a multi-colored indicator to illuminate with a first color during adjustment of the position of the wheel and to illuminate with a second color, different from the first color, when the current position of the wheel corresponds to the desired position of the wheel.

20. The method of claim 17 , comprising, using the controller, varying a rate of adjustment of the position of the wheel proportionally with the ground speed of the agricultural implement while the agricultural implement travels between 0.5 and 5 miles per hour.
