Abstract

A system includes an agricultural vehicle, a rear-mounted mower coupled to the agricultural vehicle by a rear hitch, a front-mounted mower pivotably coupled to a front hitch of the vehicle by a pivot member and at least one pivot-adjustment mechanism, and a control system configured to control the front-mounted mower. The control system includes processing circuitry configured to obtain a steering angle signal from a sensor, assign a value to the signal, determine if the value exceeds a first threshold, and responsive to determining that the value exceeds the first threshold, transmit a first instruction to adjust the at least one pivot-adjustment mechanism from a first position to a second position.

Claims (48)

1. A system comprising:

an agricultural vehicle;

a rear-mounted mower coupled to the agricultural vehicle by a rear hitch;

a front-mounted mower pivotably coupled to a front hitch by a pivot member and at least one pivot-adjustment mechanism, the front hitch removeably coupled to the agricultural vehicle; and

a control system configured to control the front-mounted mower, the control system comprising processing circuitry configured to:

obtain a signal from a sensor, the sensor configured to determine a steering angle of the agricultural vehicle;

assign a value to the signal;

determine if the value exceeds a first threshold;

responsive to determining that the value exceeds the first threshold, transmit a first instruction to adjust the at least one pivot-adjustment mechanism from a first position to a second position;

execute the first instruction by adjusting the at least one pivot-adjustment mechanism from the first position to the second position;

responsive to the value not exceeding the first threshold, determine if the value exceeds a second threshold;

responsive to determining that the value exceeds the second threshold, transmit a second instruction to adjust the at least one pivot-adjustment mechanism from the first position to a third position; and

execute the second instruction by adjusting the at least one pivot-adjustment mechanism from the first position to the third position.

2. The system of claim 1 , wherein the at least one pivot-adjustment mechanism is a hydraulic piston and cylinder mechanism.

3. The system of claim 1 , wherein the sensor is communicably coupled to a steering mechanism of the agricultural vehicle to measure the steering angle of the agricultural vehicle.

4. The system of claim 1 , wherein the sensor is communicably coupled to the processing circuitry by a universal control module (UCM) of the agricultural vehicle.

5. The system of claim 1 , wherein the processing circuitry is communicably coupled to the at least one pivot-adjustment mechanism by an international organization for standardization bus (ISOBUS).

6. The system of claim 1 , wherein the first position is a neutral position, the second position is an extended position, and the third position is a retracted position.

7. The system of claim 1 , wherein the second position adjusts the front-mounted mower to a position perpendicular to a direction of travel of the agricultural vehicle.

8. A control system comprising processing circuitry configured to:

obtain a signal from a sensor, the sensor configured to determine a steering angle of an agricultural vehicle;

assign a value to the signal;

determine if the value exceeds a first threshold;

responsive to determining that the value exceeds the first threshold, transmit a first instruction to adjust at least one pivot-adjustment mechanism pivotably coupled to a front-mounted mower from a first position to a second position;

execute the first instruction by adjusting the at least one pivot-adjustment mechanism from the first position to the second position;

responsive to the value not exceeding the first threshold, determine if the value exceeds a second threshold;

responsive to determining that the value exceeds the second threshold, transmit a second instruction to adjust the at least one pivot-adjustment mechanism from the first position to a third position; and

execute the second instruction by adjusting the at least one pivot-adjustment mechanism from the first position to the third position.

9. The control system of claim 8 , wherein the at least one pivot-adjustment mechanism is a hydraulic piston and cylinder mechanism.

10. The control system of claim 8 , wherein the sensor is communicably coupled to a steering mechanism of the agricultural vehicle to measure the steering angle of the agricultural vehicle.

11. The control system of claim 8 , wherein the sensor is communicably coupled to the processing circuitry by a universal control module (UCM) of the agricultural vehicle.

12. The control system of claim 8 , wherein the processing circuitry is communicably coupled to the at least one pivot-adjustment mechanism by an international organization for standardization bus (ISOBUS).

13. The control system of claim 8 , wherein the first position is a neutral position, the second position is an extended position, and the third position is a retracted position.

14. The control system of claim 8 , wherein the second position adjusts the front-mounted mower to a position perpendicular to a direction of travel of the agricultural vehicle.

15. A method comprising:

obtaining, by a processor, a signal from a sensor, the sensor configured to determine a steering angle of an agricultural vehicle;

assigning, by the processor, a value to the signal;

determining, by the processor, if the value exceeds a first threshold;

responsive to determining that the value exceeds the first threshold, transmitting, by the processor, a first instruction to adjust at least one pivot-adjustment mechanism pivotably coupled to a front-mounted mower from a first position to a second position;

executing, by the at least one pivot-adjustment mechanism, the first instruction by adjusting the at least one pivot-adjustment mechanism from the first position to the second position;

responsive to the value not exceeding the first threshold, determining, by the processor, if the value exceeds a second threshold;

responsive to determining that the value exceeds the second threshold, transmitting, by the processor, a second instruction to adjust the at least one pivot-adjustment mechanism from the first position to a third position; and

executing, by the at least one pivot-adjustment mechanism, the second instruction by adjusting the at least one pivot-adjustment mechanism from the first position to the third position.

16. The method of claim 15 , wherein the at least one pivot-adjustment mechanism is a hydraulic piston and cylinder mechanism.

17. The method of claim 15 , wherein the sensor is communicably coupled to a steering mechanism of the agricultural vehicle to measure the steering angle of the agricultural vehicle.

18. The method of claim 15 , wherein the sensor is communicably coupled to a processing circuitry by a universal control module (UCM) of the agricultural vehicle.

19. The method of claim 15 , wherein the first position is a neutral position, the second position is an extended position, and the third position is a retracted position.

20. The method of claim 15 , wherein the second position adjusts the front-mounted mower to a position perpendicular to a direction of travel of the agricultural vehicle.
