Abstract

In one aspect, a system for controlling ground-engaging tools of an agricultural implement may include first and second ground-engaging tools configured to perform first and second operations, respectively, on a field as the agricultural implement is moved across the field. Furthermore, a controller of the disclosed system may be configured to determine a first value of a field characteristic based on the received sensor data and adjust an operating parameter of the first ground-engaging tool based on the determined first value. After adjusting the operating parameter of the first ground-engaging tool, the controller may be configured to determine a second value of the field characteristic based on the sensor data and adjust an operating parameter of the second ground-engaging tool based on the determined second value.

First claim

The invention claimed is:

1. A system for controlling ground-engaging tools of an agricultural implement, the system comprising:
a first ground-engaging tool configured to perform a first operation on a field as the agricultural implement is moved across the field;
a second ground-engaging tool configured to perform a second operation on the field as the agricultural implement is moved across the field, the second ground-engaging tool being of a different type than the first ground-engaging tool;
a sensor configured to capture data indicative of a field characteristic of the field; and
a controller communicatively coupled to the sensor, the controller configured to:
determine a first value of the field characteristic based on the data captured by the sensor;
adjust an operating parameter of the first ground-engaging tool based on the determined first value;
after adjusting the operating parameter of the first ground-engaging tool, determine a second value of the field characteristic based on the data captured by the sensor; and
adjust an operating parameter of the second ground-engaging tool based on the determined second value.

2. The system of claim 1 , further comprising:
a third tool configured to engage the soil as the agricultural implement is moved across the field, the controller being further configured to:
after adjusting the operating parameter of the first ground-engaging tool, adjust an operating parameter of the third tool based on the determined second value of the field characteristic.

3. The system of claim 1 , further comprising:
a third tool configured to engage the soil as the agricultural implement is moved across the field, the controller being further configured to:
after adjusting the operating parameter of the second ground-engaging tool, determine a third value of the field characteristic based on the data captured by the sensor; and
adjust an operating parameter of the third tool based on the determined third value of the field characteristic.

4. The system of claim 1 , wherein the controller is further configured to:
adjust the operating parameter of the first ground-engaging tool based on a ground speed of the agricultural implement in addition to the determined first value of the field characteristic; and
adjust the operating parameter of the second ground-engaging tool based on the ground speed of the agricultural implement in addition to the determined second value of the field characteristic.

5. The system of claim 1 , wherein the controller is further configured to:
adjust the operating parameter of the first ground-engaging tool based on a draft load applied to a work vehicle by the agricultural implement in addition to the determined first value of the field characteristic; and
adjust the operating parameter of the second ground-engaging tool based on the draft load in addition to the determined second value of the field characteristic.

6. The system of claim 1 , wherein the controller is further configured to:
after adjusting the operating parameter of the second ground-engaging tool, determine a third value of the field characteristic based on the data captured by the sensor; and
adjust a ground speed of the agricultural implement based on the determined third value of the field characteristic.

7. The system of claim 1 , wherein the first ground-engaging tool comprises one of a disk, a leveling blade, a shank, or a basket and the second ground-engaging tool comprises another of the disk, the leveling blade, the shank, or the basket.

8. The system of claim 1 , wherein the first ground-engaging tool comprises a leveling blade and the second ground-engaging tool comprises one of a disk or a shank.

9. The system of claim 1 , wherein the field characteristic comprises at least one of residue coverage, soil clod size, soil levelness, or compaction layer depth.

10. A method for controlling ground-engaging tools of an agricultural implement, the agricultural implement including a first ground-engaging tool configured to perform a first operation on a field as the agricultural implement is moved across the field, the agricultural implement further including a second ground-engaging tool configured to perform a second operation on the field as the agricultural implement is moved across the field, the second ground-engaging tool being of a different type than the first ground-engaging tool, the method comprising:
determining, with one or more computing devices, a first value of a field characteristic of the field based on received sensor data;
adjusting, with the one or more computing devices, an operating parameter of the first ground-engaging tool based on the determined first value;
after adjusting the operating parameter of the first ground-engaging tool, determining, with the one or more computing devices, a second value of the field characteristic based on the received sensor data; and
adjusting, with the one or more computing devices, an operating parameter of the second ground-engaging tool based on the determined second value.

11. The method of claim 10 , wherein the agricultural implement further includes a third tool configured to engage the soil as the agricultural implement is moved across the field, the method further comprising:
after adjusting the operating parameter of the first ground-engaging tool, adjusting, with the one or more computing devices, an operating parameter of the third tool based on the determined second value of the field characteristic.

12. The method of claim 10 , wherein the agricultural implement further includes a third tool configured to engage the soil as the agricultural implement is moved across the field, the method further comprising:
after adjusting the operating parameter of the second ground-engaging tool, determining, with the one or more computing devices, a third value of the field characteristic based on the received sensor data; and
adjusting, with the one or more computing devices, an operating parameter of the third tool based on the determined third value of the field characteristic.

13. The method of claim 10 , further comprising:
adjusting, with the one or more computing devices, the operating parameter of the first ground-engaging tool based on a ground speed of the agricultural implement in addition to the determined first value of the field characteristic; and
adjusting, with the one or more computing devices, the operating parameter of the second ground-engaging tool based on the ground speed of the agricultural implement in addition to the determined second value of the field characteristic.

14. The method of claim 10 , further comprising:
adjusting, with the one or more computing devices, the operating parameter of the first ground-engaging tool based on a draft load applied to a work vehicle by the agricultural implement in addition to the determined first value of the field characteristic; and
adjusting, with the one or more computing devices, the operating parameter of the second ground-engaging tool based on the draft load in addition to the determined second value of the field characteristic.

15. The method of claim 10 , further comprising:
