Abstract

An agricultural implement includes at least one row unit having a plurality of support members, each of which is pivotably coupled to an attachment frame or another of the support members to permit vertical pivoting vertical movement of the support members, and a plurality of soil-engaging tools, each of which is coupled to at least one of the support members. A plurality of hydraulic cylinders are coupled to the support members for urging the support members downwardly toward the soil. A plurality of controllable pressure control valves are coupled to the hydraulic cylinders for controlling the pressure of hydraulic fluid supplied to the cylinders. A plurality of sensors produce electrical signals corresponding to predetermined conditions, and a controller is coupled to the sensor and the controllable pressure control valves. The controller receives the electrical signals from the sensors and produces control signals for controlling the pressure control valves.

Claims (19)

1. A hydraulic control system configured to control an up force and a down force relative to an agricultural implement, comprising:

a hydraulic cylinder housing a double-acting ram;

a first energy storage device and a second energy storage device coupled to the double-acting ram via a first controllable valve to control supply of pressurized fluid to the hydraulic cylinder;

a fluid sump coupled to the hydraulic cylinder to control return of pressurized fluid to the fluid sump;

an electrical controller operatively coupled to the first controllable valve to cause selective opening and closing of the first controllable valve and to thereby cause at different times selective application of the up force and the down force relative to the agricultural implement in response to or at least partially based on at least a GPS coordinate signal received from a GPS system.

2. The control system of claim 1 , wherein the GPS coordinate signal is indicative of a speed of the agricultural machine.

3. The control system of claim 2 , wherein the electronic controller is configured to cause the down force to be adjusted based on a soil-hardness signal indicative of a hardness of soil that the agricultural implement is traversing.

4. The control system of claim 2 , wherein the electronic controller is configured to cause at different times selective application of the up force relative to the agricultural implement.

5. The control system of claim 1 , wherein the electronic controller is configured to cause the down force to be adjusted based on a soil-hardness signal indicative of a hardness of soil that the agricultural implement is traversing.

6. The control system of claim 5 , wherein the electronic controller is configured to receive sensor signals from the agricultural implement and/or a ground-engaging tool to develop a graphical representation of a field.

7. The control system of claim 1 , wherein the electronic controller is configured to cause at different times selective application of the up force relative to the agricultural implement.

8. The control system of claim 1 , wherein the electronic controller is configured to form a soil condition map from at least the GPS coordinate signal.

9. The control system of claim 1 , wherein the electronic controller is configured to receive sensor signals from the agricultural implement and/or a ground-engaging tool to develop a graphical representation of a field.

10. The control system of claim 9 , wherein the electronic controller is further configured to provide an interactive map with GPS coordinate locations of conditions associated with the field.

11. The control system of claim 10 , in combination with a display configured to display the interactive map, the display optionally including a touchscreen and depicting a control panel relative to the touchscreen.

12. The control system of claim 11 , wherein the conditions include any one or more of soil compaction, moisture, in-field obstacles, or a condition related to soil fertility.

13. The control system of claim 1 , wherein the GPS coordinate signal is indicative of a position of the agricultural implement.

14. The control system of claim 1 , in combination with a plurality of row units of or coupled to the agricultural machine.

15. An agricultural machine comprising the control system of claim 1 .
